ABOUT THE DIRECTORY
Start with the model number.
WaterFilterList is a reference for U.S. household water filters. It connects system models, replacement items and specific documented performance claims.
What is in the directory
The current catalog contains 94 model records from 8 manufacturers and 146 reviewed configurations. The most recent document review is dated 2026-09-21. Documented color aliases remain part of one model record.
Coverage includes both new and older systems. Retaining an older model helps people find its replacement filters; a listing does not establish current retail availability.
How this work is produced
Records are assembled from public certifier listings and manufacturer documents. The source, access date, review date and reviewer are attached to each configuration. Catalog assembly and the initial document review were assisted by Codex. This site has not independently laboratory-tested these systems and does not claim expert human review where none occurred.
Editorial and commercial policy
There are no paid rankings or affiliate purchase links in this release. Catalog order is for browsing and is not a performance ranking. Manufacturer trademarks identify the products; the manufacturers do not sponsor this directory.
Corrections and scope
When a source disagrees with a record, the original model-specific document and its conditions require checking. Missing information is labeled rather than inferred. Pending imports are withheld from public pages until a review is recorded.
