This 20″ replacement filter for the Low Maintenance Pre-Filter lasts for up to 6 months — 3X as long as our standard pre-filter. This pre-filter is the first line of defense in your whole house filtration set-up, capturing dirt, rust, sediment, and silt that can clog your system.
Aquasana’s pre-filters are engineered for easy replacement. Simply twist off, replace, and screw back on — no tools or plumber required.
