Keep the water clean. Each activated-charcoal filter removes debris, hair, and odor — so your cat drinks fresh, not stale.

Replace every 2–4 weeks depending on how many cats use the fountain. Rinse under cool water before first use, then drop it in.

6-pack = about 3 months of clean water
12-pack = about 6 months
20-pack = about 10 months

Fits the Loaf Fountain.
