These have proved to be ideal
Believe me when I say that "longevity" is not an applicable evaluation point for a cat fountain filter. I change the water in my cat fountain every other day, because they can drop hairs or impurities into the water easily and I like it to be clean for them, and I wash the fountain down as well. Some people change their fountain filter once a month, but I would rather do it twice a month, since it inhibits the growth of that clear algae which forms on the parts of the fountain bowl and the "waterfall" chute that are covered in still water. The fountain itself-- with moving water-- is the reason my kitties are so happy to lap up copious amounts of water and thus decrease the odds of renal failure or disease. But the purity of the water is also important, which is why these filters are so useful. They do their job so I know their water is safe, although part of my peace of mind regarding that, is also due to the fact I use spring water in their fountain. We don't have the incredibly pure well water coming from the faucets in our current home that we had a few years ago, and the city water is chlorinated, which I'm leery about drinking and so I don't like them having to either. The charcoal content is adequate for inhibiting the growth of fountain slime for longer, but it won't leave behind much charcoal residue either. The reasonable cost of these make it painless to change the filter every other week, or even more often. (My son used to insist that the Cat Mate brand of filter uses more charcoal and so they last longer, but in spite of the higher cost, they ALL get so funky looking--who wants to keep the same one of those things in your cat's drinking fountain for a month--ugh!!) And BTW, he was never good about changing his cat's fountain either, so I thought his point about buying the expensive brand was moot. The Cat Mate fountains themselves are another story however, they clean up so quickly and easily and they are *not* expensive, so I think they are the best. But for your Cat Mate fountain, these 10 to a package filters are great!

Junk & chemicals get trapped in filter, water stays fresh & clean, pets drink more, filter works!
It’s kinda hard to get excited about filters but I’ll try. What excellent filters! There are 10 filters per box with each individually wrapped. Visually, they appear pre-washed but old habits die hard so I still rinse the new ones prior to first use and never found any loose particles. The filters are a perfect fit, easy to install and work well in the CatMate Pet Fountain. My pets love the fountain so by extension that includes the filter. The water quality is always clean and fresh, free of sediment, odors and taste. It is when you are changing out the filter that it becomes obvious how much junk it collects instead of circulating it back into the water. At a buck fifty per filter, it’s a great price to pay when it guarantees your pets will continue to drink plenty of fresh and clean water. My one cat that had bladder stone surgery and wasn’t drinking enough water, but thanks to CatMate, all the pets are now drinking much more water. Overall, I’m happy with the performance of the filters. What can I say? They work!!!!! I change out every Monday and you can actually see the difference of old vs new!

Excellent value
We’ve been using these filters for years. Never had a bad one in the box that leaked carbon or wasn’t sealed properly. They work and are cheap. Change them super regularly and never had any issues with multiple cats using the fountain.

Filter is high quality and not as restrictive as the original filter.

Buen precio y buena calidad
No esperen la misma calidad que los originales pero cumplen su función y duran buen tiempo. Solamente me toco unos filtros que tenían algunos carbones rotos, saqué esos carbones rotos y limpié la carcasa y funcionaron sin problema

Bon rapport qualité prix
Bien plus économiques et apparemment aussi efficaces que les originales. Bien les rincer avant de les mettre en place pour enlever l'excédent de charbon
