Best Whole House Water Filter

Jump to Section

The best whole house water filter for your home is the one that meets all of your needs. There are many different types of whole house water filters, and they all have their pros and cons.

In this article, we'll take a look at the different types of whole house water filters and the pros and cons associated with them. We'll also talk about how to choose one that will work for you – let's get started.

Different types of house water filtration system

The main difference between whole house water filters is whether or not they remove fluoride from your water.

Let's have a look at some of these are the different types of filters to explore which one is best for you:

Whole house carbon block filter

This type of filter is installed on the cold water line entering your hot water tank and goes into effect as soon as you turn on a faucet in your home. This type of filter removes chlorine, sediment, particles that can clog up pipes, and odor – it's also known to reduce rust stains from toilets.

Pros: Very effective at treating both hard (high mineral content) and soft (low mineral content) water.

Cons: Does not remove fluoride from water, so you will still need a reverse osmosis or ion exchange filter if you want to remove fluoride from your drinking water. Sometimes this type of filter will not work on heavily contaminated water because it cannot keep up with the flow of water. This is especially true if your home has more than 4 people using it.

Granular activated carbon (GAC) filter

This is another type of whole house water filter that you can choose from. It works by removing chlorine and most odor and taste problems, though this one does not remove fluoride, either. The biggest benefit of a GAC system over other types of whole house water filters is that it doesn't require back-flushing like others do to restore capacity – instead, all you need to do is pump out the sediment occasionally. On average this type of filter lasts for two years before needing replacement.

Pros: Easy to install and doesn't require back-flushing after installation.

GAC effectively removes 99% of chlorine, heavy metals, hydrogen sulfide (rotten egg), and iron from your water. This type of filter can work for both hard and soft water. 

Cons: Does not remove fluoride from water, so you will still need a reverse osmosis or ion exchange filter if you want to remove fluoride from your drinking water. These filters are more expensive than other whole house water filters that do the same job. Also, they can let through bacteria sometimes because they are exposed to air while going through the filtration process.

GAC filters are good for large homes with a lot of people using the water, but can't keep up with smaller households or heavily contaminated water. If you have moderately contaminated water, these should work fine though. If your water is extremely hard and contains high levels of mineral salt, this type may clog too easily and become ineffective at filtering out minerals.

Reverse osmosis water filtration system [also known as “RO”]

This type of whole house water filter utilizes a special membrane to remove most impurities from your tap water – it effectively removes everything except fluoride (which means you will still need an ion exchange or reverse osmosis filter if you want to remove fluoride from your drinking water). 

Pros: Effective at removing nearly all impurities, including bacteria and viruses. This type of filter is very easy to install. You get great-tasting water from this system right away, though it does take a few hours for the water to be purified. This whole house water filtration method lasts for several years before you need to replace it.

Cons:Water treated with this filtration method can taste overly sweet, which may require some getting used to. Both the installation cost and the cost of replacement membranes are high. This filtration method is the most expensive type you can choose.

These filters can let through bacteria because they are exposed to air while going through the filtration process, so you need to install a powerful pre-filter (basically a screen) before installing this whole house water filter if you want to avoid bacterial infections in your household.

Ion exchange water filtration system [also known as “IX”]

Ion exchange uses resin beads to replace mineral ions and other dissolved solids that are found in hard water. This kind of whole house water filter effectively removes 99% of chlorine and heavy metals from the tap water and works for both soft and hard water with proper bead replacement. 

These whole house water filters are very effective at removing bacteria from the water, too, and only need to be replaced every 5-7 years. If your water is moderately hard or slightly contaminated, but not extremely hard or heavily polluted, this should work well for you. However, if your water is on the harder side or contaminated with heavy metals like lead or copper, a granular activated carbon (GAC) filter may be a better choice.

Pros: Effective at removing both chlorine and many other harmful contaminants that traditional filtration methods can't remove. Have no moving parts so they are reliable and will pump out great-tasting water for the length of their lifespan. 

Cons: The cost to install one of these is fairly high, though it does save money in the long run because they last for many years and don't need to be replaced very often. If your water is moderately hard or slightly contaminated, but not extremely hard or heavily polluted, this should work well for you. However, if your water is on the harder side or contaminated with heavy metals like lead or copper, a granular activated carbon (GAC) filter may be a better choice.

Sediment water filtration system [also known as “SED”]

A sediment water filter removes sediment from your water. Sediment can cause many problems in your home, but a good sediment water filtration system prevents this by eliminating the particles that carry additional harmful contaminants. Fluoride removal: Yes These whole house water filters are great for removing bacteria – they're very effective for even heavily contaminated or hard to treat water at reducing impurities, though they don't reduce fluoride levels in the water like other methods do. This type of whole house filtration is very efficient and only needs to be replaced about once every few years. They're also relatively inexpensive to install and have no moving parts.

Pros: This type of whole house filtration has no moving parts and doesn't need to be replaced very often. It's also the best choice for bathing because it does not remove healthy minerals from the water as most other filters do – only sediment or other impurities you don't want are filtered out. 

Cons: This type of filter will add a slight sulfur smell to your water, so if you have extremely sensitive taste buds this might not be the best fit for you. Also, this type of filter does not remove all fluoride from the water, which may be important if you have children in your household.

Moreover, since this type of filter does not remove chlorine from the water, if your home is connected to a municipal water supply that uses chloramine in its purification process you may still want to use an additional point of filtration – such as a reverse osmosis system – to remove any trace amounts of chloramine. Overall, though, sediment filters are excellent at removing impurities and contaminants that can cause health problems in your household.

FAE, or “Fluoride Attack Eliminator”

A fluoride attack eliminator (FAE) is a whole house filter that will help reduce the amount of fluoride consumed in your home's water.

Fluoride has been found to greatly increase the risk of both cancer and osteoporosis. At least 50% of Americans drink water from sources with excessive levels of this substance, which may be detrimental to one's health. A fluoride attack eliminator will remove much of the contamination in your drinking water, helping you avoid unnecessary exposure.

Pros: A fluoride attack eliminator adds an extra level of protection against the amount of fluoride consumed in your household's drinking water. It's also very affordable to install and maintain, which is a huge plus.

Cons: This type of filter is less effective at removing contaminants that can cause serious health issues, such as bacteria and heavy metals like lead or copper. Also, these filters are not recommended for homes with well water because they aren't designed for this – you should look into a reverse osmosis system if you have a well instead. 

Questions to ask before you buy your next home water filtration system 

Before you buy your next whole house water filtration system, ask yourself the following questions:

What kind of water quality do I have? 

Is it hard water, soft water or does my water contain a lot of dissolved minerals like calcium and magnesium?

This is important to ask because your water quality will determine which type of whole house filtration system is best for you – a hard water filter, soft water filter, or a combination of both. If your home's water is hard or contains high levels of dissolved minerals you'll want to purchase one that will remove these substances from the water – either on its own or in conjunction with another type of filtering system.

Water Quality

How would I like my drinking and bathing water to taste, look and feel?

If you're looking for sparkling clean-tasting drinking water this might be the most important question on this list because it will enable you to choose one that matches all three descriptions perfectly. Your next step should be reading reviews online about different systems and talking with people who have already installed one in their homes.

How much water do I use?

You may not want to consider this at first glance, since it's the most obvious question, but it's still worth asking because it will give you a better idea of just how much you're saving by installing a whole house filtration system. A more efficient system means less waste and lower utility bills for your household – which makes this a very important thing to think about.

Am I concerned with the health risks associated with drinking water impurities?

If the answer is yes, then you'll want to make sure you choose a whole house filter that can remove unwanted contaminants from your household's drinking and bathing water. This will help protect the ones you love from disease and illness caused by these impurities.

These are some important questions to ask before buying your next home water filtration system. You may want to print this off and keep it near your computer or in a notebook so that you can refer to it when shopping for the right filter.

Know the terms associated with whole house water filters.

You'll want to familiarize yourself with some of these common terms before deciding which type of filtration system is best for you and your household:

Components: This is simply a fancy way of saying parts or components. The more components your filter has, the better job it will do purifying your water – but this also means it will cost you more money up-front and in the long run. For example, a carbon block filter can remove contaminants found in drinking water much better than a traditional sediment filter because it contains three separate types of filtering media that work together to make sure they don't miss anything. However, this type does cost a little more. 

Sediment filters are much less expensive than carbon block filters, but they're also not as good at removing impurities.  

Point-of-use system: This type of whole house filter is designed to remove contaminants from the water supply at the point where it enters your home before going on to other parts of your home via the main water line.   

Inline system: An inline filtration system is attached directly to your main water supply and removes contaminants as the water passes through it. 

Point-of-entry system: The POU or POE filtering system sits outside by the curb and can be used for either private homes or businesses that have their water supply.

Centralized vs Decentralized Water Treatment Systems

Point-of-use/point-of-entry combo system: The POU/POE combo is a dual filtration system that serves the same purpose as the two by itself – removing contaminants from public or private wells, lakes, and other sources of municipal water. 

Carbon block filters: This type of filter uses carbon-based media to remove contaminants like chlorine and bad tastes and odors from your household's drinking water. Carbon block filters are designed for point-of-use systems that treat small amounts of water quickly (like drinking glasses) before putting it back into the main distribution system.   

Carbon sediment filters: These types of whole house water filters use activated carbon in their media to remove contaminants like chlorine and other impurities from both the drinking water and also any bathwater that's run through your house. 

Reverse osmosis filters: An RO filter is a type of point-of-entry system that uses reverse osmosis technology to purify large amounts of water quickly. You can combine an RO filter with another filtration system, such as softening or deionization, for a more complete solution in protecting your household from contaminants in their drinking and bathing water. 

Granular activated carbon (GAC) filters: These are similar to carbon sediment filters except they use granules instead of pellets. 

Fluoride removal filters: If you live in an area where the tap water contains fluoride, you might want to consider a filter that's designed specifically for removing this ingredient from your drinking water. 

Softening filters: These types of whole house filters use ion exchange technology or salt-free resins and chemicals to “soften” the hardness of your household's water. This process can also remove certain contaminants like lead, nitrates, and other harmful substances found in municipal city waters. 

Standard filters: In comparison to point-of-entry systems, these are less expensive types of whole house filters because they're generally not as good at reducing levels of contaminants.

You'll want to make sure that whatever type of system you buy matches the capacity of your household's water consumption. For instance, if you have a large family and the home is set up to supply each member with plenty of hot showers throughout the day, then you'll want to buy a system that has enough filtration media to handle this demand.  Speaking of showers, have a look at the best water softener shower heads you can buy in 2021.

You should also think about how much space you have around where the filter will be installed. A point-of-use or in-line system, for example, can take up very little room because it sits directly on top of your main water line and connects directly into the plumbing.

What is the ROI of installing a new, high-quality whole-house filtration system in your home?

Another thing to consider is the ROI – or return on investment – that you will get by installing a new, high-quality whole house filtration system in your home. 

The ROI for many of the best whole house water filters is very high, but some of them might not seem like they are worth the initial cost when compared to other options – let's take a look at why this isn't always true and how it could affect your decisions.

Let's start with replacement filter costs. Some of the best whole house systems won't require you to replace their carbon or sediment filter every year or even every two years because these types of components only need to be replaced after removing hundreds or thousands of gallons of contaminants from your drinking water over time.

The next thing to consider is that whole house water filtration systems can end up saving you money in the long run because of less energy and labor costs you would have if your system was functioning properly (considering how much time it takes to scrub mineral deposits off your shower tile, bathtub and taps).

You'll also find that after installing a good quality whole house system and having good-quality water at every tap in your home, your family will be less sick. This will result in higher productivity levels at work for anyone who's affected by these illnesses.

In all, many different ways of investing in a new high-quality whole house filter system can help you save money on utility bills – both now and in the future.

The ROI of each whole house water filter will vary depending on the number of contaminants it removes from your household's drinking water. So, one option that is often a good idea to consider when looking at ROI is something called payback – or the period needed for you to recover the initial cost of installing and maintaining your whole house system. 

Another thing to keep in mind is what kind of quality and performance you'll get out of each system you're considering buying. Factors such as how efficient each type of system is at removing different kinds of impurities will affect its ROI. Also, make sure you pay close attention to how long each type of system lasts because the longer they last, usually means less money needs to be spent on replacement filters.

Maintenance issues with a whole house water filter 

Let's now dive a bit deeper into maintenance issues with a house water filtration system. This might seem like a no-brainer, but one thing you'll want to do before making any purchase is ask yourself what backs up your house lines. If the water that backs up behind your pipes is clean and clear (and not yellow or green), then it's probably okay for your whole house system.

The other things you might need to consider are space issues, the total amount of flow required by your whole home, and which type of filtration system will be best suited for your family's needs. These types of considerations should help you narrow down all the choices that are currently available on the market today.

Next, you'll need to figure out where you want to install your new whole house water filtration system. You can choose between a basement, crawlspace, or above-ground location – just make sure you have easy access to the filter and that it's accessible in case of an emergency.

The next thing you'll need to consider is tap locations. Whether they're installed on sinks and baths or kitchen taps, each type of sink should be unique because it depends on how many people will use them every day, their volume, and how often they're used.

The last thing we'll talk about when it comes to maintenance issues with a whole-home filtration system is choosing the right kind of replacement filters. Choosing inexpensive replacement filters for your filtration system might seem like a good idea, but the truth is that doing so can lead to extra costs in the long run.

Common mistakes made when buying a whole house water filter system 

Now that we've taken a look at the different types of whole house water filters and how to choose one, it's time to take a look at some common mistakes made when buying a filtration system.

The first mistake is overestimating what the capabilities of each type of filter are. Some people think if they get a filtration system that removes chlorine or fluoride, then their water will be pure enough for them to drink without having to do anything else. The thing is though, that there are many other contaminants out there you might need to worry about also – including lead. This is why it's always important to read product reviews before making any purchases.

Also, another mistake people make is not choosing a whole house system because they believe it's too expensive. Commercial filters are inexpensive – as in, you can get a good RO (reverse osmosis) filter for your home for under $100.

Another common mistake people make is thinking that if they have a good point-of-entry filtration system then installing a whole-house water filtration system won't be necessary. Most points of entry systems indeed do an excellent job at filtering out chlorine and other contaminants from their specific water source like your sink or bathtub, but the truth is that there are still many other contaminants out there that should be considered when making this kind of purchase. 

Some experts even recommend installing a whole-home filtration system alongside your point of entry filtration system to improve overall water quality.

When buying a water filtration system for your home, don't make the mistake of thinking that it will solve all of your water issues. If you have hard water and use soap scum build-up in bathtubs or shower stalls then you'll still need to install an additional type of filter. 

This is especially true if you're planning on using any paint or cleaning products inside your home.

Another common mistake is not deciding on the type of filtration you want. All types of whole house water systems will provide you with fresh, clean drinking water – but only if they're properly maintained and installed by a company that knows what they're doing. If you plan on installing one yourself after reading this article, make sure to do some research before making any purchases.

Speaking of doing things yourself, here’s how you can make a DIY water filter system yourself if you’re up for it. This might be something alternative to consider.

Last but not least, many people just don't think about adding a system for filtering their hot water as well. This would be especially important if you use well water for your household because it contains tons of natural minerals that shouldn't be consumed in large quantities over time.

Aren't Water Softeners Enough?

Water softeners work by using ion-exchange beads to remove the hardness of the water. These beads are usually made from either sodium or potassium.

Water softener systems use a process called regeneration, which is basically what happens when you add more sodium and potassium ions into your water supply (to replace the calcium and magnesium ions taken out during the filtering process). This causes dissolved calcium and magnesium to build up inside your system's resin tanks over time.

How to Choose a Water Softener System

When this happens, you'll need to drain a lot of your water down so you can clean all that buildup out. This not only wastes a lot of perfectly good drinking water – but it also means that there isn't an operating water filter in place while this cleaning process is taking place.

For these reasons,  many experts recommend installing an additional whole house system during the same time that you install your water softener. This way you're getting the best of both worlds – great taste and clean drinking water.

How to Install a Whole House Water Filter System (and save $$$)

Installing a whole house water filter is not a difficult process if you have some plumbing experience. However, it's always a good idea to hire a professional to do the job because they'll know how to install everything correctly and make sure that it's working properly.

If you decide to install your house water filtration system yourself, these are the steps you need to follow:

  • Choose a location for the filter (usually it's installed right at your water meter) and cut a hole in your house's foundation.
  • Place the new filtration system inside this hole, connect all of its pipes and make sure that everything is connected properly.
  • Run electric and plumbing lines from your home's wall to the engine room where you'll place taps or faucets to serve drinking water.
  • Install an automatic shut-off valve at one end so that if there are any leaks or other problems they can be easily addressed.

Let's take a deeper look at each of these points.

Choose a location for the filter 

You'll need to choose a location for the filter's engine room, its electrical box, and the water shut-off valve. In most cases, you'll want to place your filters somewhere near or behind your home's main water meter. This means that installing your filter will be a lot less expensive than if you were to install it at some other location.

Cut a hole in your house foundation

This step is pretty easy if you have some basic carpentry skills. If not, then it's best to hire someone who knows what they're doing – this is where it's most important to hire a trained professional plumber or experienced handyman.

Place the new filtration system inside this hole

This can get complicated because you need to make sure that all of your pipes are connected properly and going in the right direction. You also need to make sure the water meter will be able to spin freely once everything is installed. Sometimes all of these pipes require a lot of rearranging just so they'll fit together correctly – so make sure you have some extra elbow room. This is important because it can be pretty dangerous to mess with pipes when they're under pressure and connected to a water supply.

Connect all of its pipes 

Usually, your engine house will have a few hoses attached to the bottom of it (for water access). Just connect these hoses to their respective places on the new filtration system and you'll be good to go.

Make sure that everything is connected properly

Sometimes, the pipes won't fit together quite right. This will keep you from being able to connect the whole thing properly. So, make sure all of your pipes are screwed into their correct places and verify that everything lines up correctly. This is a crucial step since everything needs to be leak-proof.

Run electric and plumbing lines from your home's wall 

This is also an important part of the process. You'll need to run piping inside walls so that everything will fit together properly. If you don't know what you're doing, then this could get complicated fast.  Installation of your water filtration system varies depending on which type you buy. The difference in installation costs usually comes down to the cost of running electric/plumbing wiring.

Install an automatic shut-off valve at one end

This step is simply to ensure that if there are any problems in your house's plumbing system, you'll be able to isolate the problems and get everything fixed promptly. For example, if you lose power or have some other problem with the filter tank, then this automatic shut-off valve will activate and shut down all water flow from your home so it doesn't leak out. Finally, you should have some kind of shut-off valve at the end where the filtered water will enter your home. This is an important safety precaution that can keep you, or a member of your family, from getting hurt.

(Optional) Attach it to a cleanout port

In most cases, this step won't even be necessary if you're doing everything right and there are no problems with your plumbing system. But I would install a cleanout port anyway in case something goes wrong down the road and you need one to replace pipes or filters along your entire house's water line.

Remembering to Change Your Filters

There are some things you need to be aware of when choosing to change the original filters with replacement filters. First, make sure they fit properly, and second, know what other elements they filter besides water. This will help ensure that your new whole house filtering system continues to work well and effectively for many years to come. Filters will need to be changed from time to time. This means that you'll need to know how often they should be replaced and make sure you remember when their replacement is due.

How Often to Change Water Filter?

Check the filter's packaging 

Simply check the instructions on your new filter. They will tell you exactly when it needs to be changed (for example, once every 6 months).

Take note of your water provider's recommendations

Some companies suggest changing filters more than once a year. So, if your provider says it should be changed more frequently than what the manufacturer suggests, then go ahead and change it more frequently.

If You Have Hard Water You'll Need to Change Filters More Often

The amount of time you keep your filter has a lot to do with the number of minerals and other particles that it will collect. If you have hard water, then your filters will need to be changed more often than someone who has soft water. This is because the filters in those homes are filtering out a lot less stuff overall.

If you're not sure whether or not your water counts as “hard,” then ask others who live where you do (besides plumbers). They should know what the term refers to, since some people get water from local springs, for example.

How to Change Filters in Your Whole House Filtration System

If you want to change your filters by yourself, then you'll need to know how to get your new filters properly installed. So, here are some steps that will help.

  • Make sure the water is turned off at both ends – This step can prevent a lot of leaks and messes around your house.
  • Remove the old filter – Usually, this is as simple as unscrewing it from its mountings and letting any remaining water drain freely out of a hole in the bottom. Then just set it aside for now.
  • Prepare the new filter – If there's any mineral build-up on the outside of the filter itself, then it's a good idea to use an old toothbrush or something to clean it off. This will ensure that you don't end up with all sorts of mineral deposits on your home's plumbing system and appliances. In addition, check out these further home improvement ideas and read up on them.
  • Screw the new filter back into place – If you have a whole house water filtration system that includes expandable mounts, then this step might take more muscle than one can muster. So, if you need an extra set of hands, then ask a friend or family member for help.

Find Out What's In Your Home's Water before Filter Installation

When thinking about what filter to buy, some people are tempted to just buy the cheapest one they can find. However, doing this might not be a good idea if your water is loaded with dangerous chemicals or lead. If you don't know what's in your water, then have it tested before choosing a filtration system.

Different tests will tell you about the type of contaminants and minerals present in your home's water supply.

  • A TDS meter will help show whether there are any dissolved solids like calcium or magnesium in your home's water.
  • An Aqua test will tell you how much sediment and hardness there is in your water.
  • An Acidity or Alkalinity test will let you know whether you have acidic or alkaline water.
  • A Chlorine test will show how much of the dangerous chemical there is in your home's water supply.

When you know what type of stuff is in your home's water, then you'll be able to buy a system that filters out those particular things. This will ensure that your whole house filter keeps working as effectively as possible for many years to come.

FAQs about the best whole house water filter

Do I need a refrigerator water filter if I have reverse osmosis?

If you have a reverse osmosis system, then the answer is no. If your water tastes or smells like chemicals, you should call a plumbing company to come and take care of the issue for you. If your water is over 150 parts per million (PPM) of hardness, then you should contact a plumber to help with the problem.

Also, you might not need a refrigerator water filter if you are having your fridge serviced annually by the manufacturer. If this is not something that happens at least once a year, then you may want to invest in a good quality filtration system.

Do I need to flush a new water filter?

Yes, you do. There are many different reasons why it's a good idea to flush out your home's plumbing after installing a water filter. 

First of all, flushing the system eliminates any sediment that might be at the bottom of the tank or in the pipes.

Another reason to flush is that there could be small bits of solid matter which could damage parts of your filtration system if they got into them.It also helps eliminate chemical buildup.

Another time when flushing can help you save money is by preventing excess water from getting wasted while waiting for hot water to heat up.

Do whole house water filters remove fluoride?

Only a few models of filtration systems can remove fluoride. If you have high concentrations of the chemical in your home's water supply, then you may want to look for a filter that is known to handle it properly.

Do whole house water filters remove nitrates?

Yes, most filters do a good job of removing nitrates from the home's water. However, this is not always an easy task, with so many different stages required for the best results.

You first need to use sediment and carbon filtration – these steps are needed to ensure that all large pieces of matter get filtered out. Then, some sort of reverse osmosis or distillation process will likely be necessary to take care of the nitrates.

Finally, a final step will be needed to make sure that all traces of fluoride have been removed as well.

Some filters can handle these stages on their own – these kinds of whole house water filter systems can help you get clean water at any time, while also saving you money. By using them regularly for drinking and cooking purposes, you'll lower your bills greatly over time. These types of high-quality filtration systems are normally very cost-effective when used on an ongoing basis.

How do you know if a water filter is bad?

There are a few different things to look for that could indicate problems with filtration.

If the water doesn't taste good, then this is one sign. It will also smell weird if there's something wrong.

Another thing you can try is putting some vinegar or orange juice in your drinking water and seeing how it comes out – if there are particles of sediment left behind, then that could mean that your filter needs to be cleaned or replaced.

 Eco-Friendly Water Filter at Home

You should also examine the strainer screen on the underside of your water sink. If there is any debris after you've used the system for a while, then this indicates problems with its performance.

Can bacteria grow in water filters?

Yes, bacteria can form on the insides of water filters. However, this doesn't mean that you have to throw the system in the trash and go find a new one. 

All you need to do is clean it out from time to time – this will help make sure that it's functioning correctly.

Is an old water filter better than no filter?

No, this is generally not true. An old filter may be used as a temporary measure while you save up enough money to buy a new one. However, it can't do the job of keeping your water clean and healthy for you.

A person doesn't have to go without clean drinking water in their home just because they don't want to pay full price for a whole house water filter system. There are many different types of high-end filters available today that cost less when bought from online stores.

This isn't always easy, but there are ways to figure this out. You will want to look at reviews for various models of filters on pages like

You may also want to consult with your friends who have experience with these products or even look up information online.

The best thing you can do is just shop around – compare whole house water filter prices from many different stores. There's no reason why you should pay full price when there are deals available. It comes down to how dedicated you are to saving money, but most people would rather save than spend frivolously.

What does POU mean?

POU stands for point-of-use – this is just another term that indicates a type of water filtration system.

Some people may also call these “water pitchers”. They take out impurities from drinking or cooking water, and they're often used as supplementary equipment on top of main filters.

A POU drinking water filter can be very useful, but it won't help with larger problems like those affecting your entire home. It's best to use whole-house filtration systems if you want to get the most out of the experience.

Do water filters get moldy?

Yes, all filters can get moldy. This is a problem with any filtration system, no matter what type it is.

If you have a whole house water filter and the water smells or tastes bad, then there's probably something wrong with your filter. It will also look brownish if this happens – this could mean that it needs to be cleaned or replaced.

You should take care of this as soon as you can because mold often grows in waterways that are untreated and unclean on an ongoing basis. If you're drinking moldy water for weeks at a time without realizing it, then you could end up getting sick from various diseases. The sooner you catch these issues, the better.

If the filter has been in service for a few months or years, it wouldn't hurt to just replace it. This will extend the life of your filtration system and improve its overall health. It's not expensive or time-consuming to do this.

Also, bacteria are often found on mold spores as well – you'll want to be careful about what types of water sources you use these filters with. If you can test out whether there are any bacteria present before using them, that would be ideal.

The best solution is just to remove the filter from the water source if there are even small traces of contaminants involved. 

How do I pick out the right filter for my home?

This is a common question that most people have – they don't know how to choose between these types of products.

There are plenty of different ways you can go about this. You may want to ask your friends and neighbors who use these filters at home or even consult with an expert.

The best thing you can do is shop around online and make sure that you get an idea of what's available on the market today. Many other filters like “pitchers” aren't recommended if larger problems are affecting your water sources – it will be better to replace those first.

The basic types of filters that you'll come across when shopping for trash reduction systems are the whole house, under the sink, countertop, and point-of-use units. 

A whole house filter is capable of removing contaminants from water before it reaches your home's piping network. It attaches directly to the main pipe where the water comes in. This is generally a more expensive system that can take a bit of time to install (possibly days).

Under-sink filtration systems work quite well for smaller homes – they screw onto the existing pipes underneath your kitchen or bathroom sink. For just one faucet these models could cost anywhere between $40 and $200 for the filter.

Countertop filters can be installed in a few minutes, they work just as effectively as under-sink systems, sometimes even more so. They're also much smaller than whole house filters – take these out of their boxes, attach them to your faucets, and you'll be good to go right away. 

Point of use water filters are much better than other types at removing contaminants from your water if there's only one source available. These are very portable, but that's a tradeoff for their inability to remove contaminants from multiple sources (like an entire home). For about $10-$20, you can get a filter that will attach to your water bottle or camping canteens.

These are all relatively inexpensive ways to make sure that the water in your home is safe and drinkable. 

With the right amount of knowledge, you should be able to find the best whole house water filter for your needs – on top of this, it's often very easy and quick to install one yourself. After it's installed these filters are quite affordable and they could easily save you thousands over time.

What happens if you don't change your whole house water filter?

Water filters do need to be replaced from time to time – usually about every 6 months or so.

The vast majority of whole house water filters come with indicators that will let you know when it's time for a new filter.

If your filter has an indicator, then you'll want to change it by the time listed. If not, then you will probably begin to experience issues before this date arrives but they won't necessarily be drastic. This is a good health and safety measure, but it's also important for protecting the performance of your water filtration system.

You may notice things like discolored water or strange smells coming out of your taps as problems start to emerge. It's important to change your filters before this happens and you should schedule it with your regular home maintenance.

You could also notice some changes in your home plumbing, like strange gurgling sounds when the water reaches certain fixtures upstairs.

This is how long-term use of a filtered system can hurt performance over time – plus, some contaminants may have already made their way into your drinking water. You don't want to let this happen, so be sure that you always change out your filters promptly.

There are some larger, whole-house systems with replaceable cartridges as well – these must be changed every several months or so to keep the water in your home healthy and drinkable. 

These filters should tell you how often you need to change them – most of them have color-coded indicator lights to make things easy.

When you begin to notice a yellow light, it's time for a replacement. These are generally pretty inexpensive (between $30-$50), but they must get replaced when needed.
