Best Whole House Reverse Osmosis Systems of 2024

What Is a Whole House Filter?

A whole house water filter is designed to treat all the water entering your home, ensuring that every faucet and appliance benefits from clean, filtered water. Unlike point-of-use filters, which only address specific taps, whole house systems provide comprehensive filtration for your entire water supply. This type of system is ideal for addressing issues like hard water, chlorine, sediment, and other contaminants that can affect the taste, smell, and quality of your water throughout the home.
