ONECUTE Cat Water Fountain Filter, compatible with stainless steel dispensers

Every 1–2 weeks, swap the old cartridge in your pet's stainless-steel water fountain for a fresh one from this ONECUTE cat water fountain filter pack. You get 12 filters and 12 pre-filter sponges. Each cartridge holds three materials: activated carbon, ion-exchange resin and a cotton layer. The set is sized for stainless-steel fountains of 2 L (67 oz) and 3.2 L (108 oz) from different brands.

How these replacement filters work

As water passes through, the layers trap pet hair and debris and cut down on water impurities. The cotton layer works alongside activated carbon and ion-exchange resin, and the pre-filter sponges are included for the fountain's intake. Cartridges fit 2 L (67 oz) and 3.2 L (108 oz) stainless-steel fountains. Most stainless-steel pet water fountains sold today take this shape, according to the maker.

What buyers say about changing these filters

Three reviewers mention that the filter is easy to change, and three say it fits well. Another three note that it keeps the water clean.

Does this filter fit your fountain?

Check the filter shape before you buy, because a fountain with a different cut-out will not take this filter. The maker lists compatibility with 2 L (67 oz) and 3.2 L (108 oz) stainless-steel pet water fountains from different brands, and with most stainless-steel fountains on the market. Measure the filter seat on your fountain and compare it with the filter you are replacing.

How to prepare and change the filter

Soak the new filter for 5 minutes and rinse it thoroughly before the first use. Replace the filter every 1–2 weeks to maintain filtration efficiency. When you swap the filter, the included pre-filter sponge can go in at the same time.
