How Filter Warehouse cleans every drop

Multi-stage filtration captures particles down to 0.5 microns.

1

Sediment pre-filter

Traps sand, rust, and debris larger than 5 microns before they reach the main element.

2

Activated carbon

Adsorbs chlorine, VOCs, and bad taste — leaving water crisp and odor-free.

3

0.5-micron block

Catches lead, cysts, and microplastics that slip past standard filters.

4

Final polish

A final pass ensures clarity, balanced pH, and that fresh-spring taste in every glass.

Common questions

Quick answers

How do I know which filter fits my appliance?

Find your appliance model number (usually inside the door frame for fridges, or on a sticker under the sink) and paste it into our finder.

How often should I replace my water filter?

Most filters need replacement every 6 months or 200 gallons.

Are Filter Warehouse filters NSF-certified?

Yes — every filter is independently tested to NSF/ANSI standards.
