Note: The 1.5 and 2.0 CF models work best for most homes with 1 - 3 bathrooms and are our most popular models.

"Backwash Flow Rate" is the minimum flow rate in gallons per minute ("GPM") that is recommended for that size filter to operate properly. If your well pump can pump 10 gallons per minute for example, you could use the 2.0 CF model if you chose to, and it would work properly.

Maximum line pressure recommended 100 PSI. Maximum water temperature recommended: 100 F.

*"CF" refers to the amount of filter media included in cubic feet. A 1.5 CF has 1.5 cubic foot of filter media inside it, for example.
