Buying a whole house water filtration system is one of the best things you can do for the long-term comfort and health of your family. Such a system removes the need for constantly using new countertop or refrigerator filters to clean your drinking water and also makes a great alternative to faucet based filtration systems.
Plus, it works not just for your drinking water, but for all the water your family and appliances use - as a result it also drastically improves your shower experience, since chlorine evaporates with the shower steam and is easy to inhale in large quantities.
But how does one go about choosing a whole house water filtration system? Aren’t there way too many things to consider? Well, there are quite a few variables, yes, but for your convenience, below we’ve reviewed some of the best whole house water filters we could find on the market right now. Check them out!
This RO whole house filter system is a great option and takes first place for people that are looking for a long-term solution for their water and plumbing concerns. It comes with 3 extra filter sets for even more convenience. The system works at 3 stages – the 1st one uses a Premium Quick-Connect 5 micron sediment filter that clears all the dust, dirt, silt, sand, rust and scale particles that are trapped here in a filter, thus greatly extending the life of the whole plumbing system.
The 2nd stage utilizes a Premium 10" GAC granular activated carbon filter that removes chlorine, radon, VOCs (volatile organic compounds) and other common chemicals. This filter also removes cloudiness, offensive odors, colors and unpleasant tastes, which makes it great for improving the quality of life of your whole family.
The 3rd stage uses a 10" Premium CTO carbon block filter that removes chlorine, VOCs (volatile organic compounds, including insecticides, pesticides and industrial solvent). This leads to a significant taste improvement, making your drinking water much healthier and tastier without the need for any countertop or other types of water filters.
The connections of this system are standard 3/4 inch inlet and outlet ports, making it suitable for all standard home plumbing systems. The filters need to be changed every ~3 months.
