Does this filter fit the PetSafeOutlast Pumpless Fountain

Which way does the filter go

Answer by Chewy • Dec 22, 2025
The tab on top with an arrow will show the way to place the filter. The arrow should point down, and the black side facing the wall of the fountain.

I am always surprised when I refill the watered how much dirt, hair and who know what else has been trapped in the filter and thus not in my cat. Makes me feel like I’m really taking care of her.

Bad fountain. I took good care of this fountain that I owned for only a few months. Really liked it. However, when I changed the filter for the very first time, the fountain would no longer pump water out so the cat could drink. Very disappointing investment! Thanks!

Difficult

It is more because of the way the fountain is made that makes replacing these filters a pain. The fountain itself is not worth purchasing.

Works great

I bought this for my cat almost a year ago. It works great. The only issue is that the light doesn’t work anymore.
