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:

1. 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
Cons

2. 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
Cons

3. 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).

 

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.

Pros
Cons

4. Ion exchange water filtration system

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.
