Does what it says on the packet

Value for money.

The charcoal filters are excellent quality. They work really well to keep the water clean. My cat loves drinking nice, fresh filtered water. I would highly recommend these filters.

Excellent quality.

Easy to fit and used with my three cat's favourite drinking fountain. They last well too and reasonably priced.

filters

used in the Serenity fountain and works well/// even though I live in a soft water area and could probably get away with not using one I find that it cleans the water of hairs and other debris so I personally would not be without them..,a quick rinse removes all the bits and I can use them for quite some time

Appreciated Gifts

Gave these filters along with pet fountain as a gift to a friend. I have heard nothing but good reports about the gifts. So I am happy the recipient and her wonderful cats are also happy. Many thanks!
