About this product
This 16-piece pack of cat water fountain filters contains 8 replacement filters and 8 pre-filter sponges for 95oz/2.8L automatic pet fountains. Each filter is about 3.9 in square and 0.4 in thick, and the set is sold under model number 040. The two filter types work together in one fountain: the sponge catches debris before the water reaches the filter cartridge.
Which fountains the cartridges fit
The filters are compatible with 95oz/2.8L automatic pet fountains. Check the fountain model before purchase, because a fountain of a different capacity or design may not accept this cartridge size.
The cartridge measures roughly 3.9 in long, 3.9 in wide and 0.4 in thick, so the filter seat in the fountain has to take a square cartridge of that size.

Soaking and replacing the filters
Soak the foam filter for 5 minutes before use, then place it in the fountain. The manufacturer gives a replacement interval of every 2-4 weeks.
With 8 cartridges and 8 sponges in the pack, a buyer changing both every 2-4 weeks has eight changes on hand.
Cotton, carbon and resin in the water flow
Each cartridge uses a triple filtration system: a cotton layer, activated carbon and ion exchange resin. The cotton layer and the carbon are the parts the manufacturer says filter hair and heavy metals.
The sponge is the black pre-filter piece that sits ahead of the cartridge, and the cartridges are white. Filter material is listed as activated carbon, cotton and resin, and the pair of filters weighs 82 g (2.9 oz) in total.
