Frequently Asked Questions

The triple-layer design captures cat hair, food debris, and sediment (outer layer), removes chlorine and odors (activated carbon middle layer), and softens water for better taste (ion exchange resin inner layer).

The 6-Pack is the best value — it's enough for about 3–6 months and works out to $4.17 per filter vs $4.99 per filter in the 3-Pack.
