FAQ

Does a bigger house need a bigger filter system?
Yes — whole-home system capacity should be sized to your household’s water usage volume, which generally scales with home size and occupant count.

Important

Confirm system sizing with your installer based on your specific home’s water usage rather than a general size assumption.
