GLACIER FRESH Replacement Filter for Maximum Under-Sink System, 2-Pack, 4US-MAXL-S01 Compatible

Unlock better-tasting water with GLACIER FRESH

The replacement filter is designed for the Maximum Under-Sink System and is compatible with Filtrete 4US-MAXL-S01 and 4US-MAXS-S01, plus 4US-MAXL-F01 in some configurations. The 2-pack offers convenience and continuity for households that filter daily beverages, cooking water, and cold taps. Once installed, you can maintain your filtration routine with minimal disruption to cabinet space.

In practice, you may notice water with a cleaner profile—less of the earthy or musty notes that can sometimes accompany extended use of older cartridges. The filter is designed to preserve essential minerals to keep water tasting balanced and fresh, while unpleasant flavors or aromas are addressed through the filtration media.

The design emphasizes a compact footprint and straightforward operation. It slides into your existing housing, reducing complexity and allowing you to maintain a tidy under-sink area. If you’re upgrading from a legacy cartridge, you’ll appreciate the intuitive swap and the solid seal that prevents leaks.
