- Households comparing filters and replacement cartridges
- Worth noticing
- It separates materials standards from contaminant-reduction evidence and lists rated capacity where documented.
Field notes
The directory organizes 94 documented systems across eight manufacturers and exposes filters for system type, manufacturer, and specific contaminants including lead, PFAS, nitrate/nitrite, and microplastics. Records pair system and cartridge identifiers with capacity and an evidence label; the site notes that a materials standard alone does not establish contaminant reduction. One record explicitly marks capacity as not verified.
