A whole house water filter is a filtration system designed to purify all the water entering your home. Installed at the main water supply, this system ensures that every faucet, showerhead, and appliance receives filtered water.
A whole house water filter typically includes multiple stages: a sediment filter to remove dirt, rust, and large particles, and activated carbon to eliminate chemicals like chlorine. Some systems may also feature specialized filters for additional purification, such as UV filters for bacteria and viruses or reverse osmosis for extra fine filtration.
This system works continuously to improve the quality of the water you drink, cook with, bathe in, and use around the house, making it a comprehensive solution for your household’s water needs.
