Replacement Water Filter Cartridges for Cat Mate & Dog Mate Fountains, Pack of 10

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!

Ottimo prodotto e ormai un acquisto scadenzato da fare avendo tre fontanelle in casa :o)

Used for cat mate fountain. Works great. Easy to use filters.

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

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
