Petmate Replendish Charcoal Replacement Filters Control Chlorine (packaging may vary), 6 Count

Works great!

I have 5 Siberian Huskys and this is definitely a game changer, makes things so much easier and its worth every penny, no mold no mildew just fresh clean water, of course it gets washed out every other day because I have so many dogs but when I wash it there is no slime buildup or anything like there would be in their older water bowls and I had to wash them 4 or 5 times a day and refill the water 8 to 10 times so this product definitely makes life easier and I do plan on purchasing more

These work good

The product works good from what I can tell. I've never used a large drinking container like this that required filters. It's very easy to replace and is fairly durable as well.

I have the Replendish waterer for my cats, and these are brand name and the perfect filter replacement for it! I like that they are individually wrapped to keep their freshness, although the tight wrap can be a little difficult to get off. I also like that these included an extra filter strap to keep them in place, just in case you may have lost or broken it. As a side note, make sure you do run the filter under water or even let soak in a bowl of water for a bit before actually putting it in your waterer.I do find it strange that when I purchased these 3 days ago, they cost me less than $4.50 including tax, and now as I'm writing this review the price has literally doubled. I did think to myself that they were very affordable here, as I can only imagine these would've been between $7-$10 at Petco, but they didn't have them when I went. Will definitely purchase again in the future if the price goes back down by the time I'm looking for them next.

I bought several of these charcoal filters for two Replendish water bowls. It was becoming too expensive to keep buying filters. I also have a Drinkwell 360 Steel fountain ( I have three cats and sometimes more when I foster). I purchased Marineland Premium Activated Charcoal, which I use in the reusable Drinkwell fountain filter.I did not throw out the used Replendish filters. Since these filters are made from sturdy fabric, I let them dry out and then cut a 1 inch slot in the middle of the top side. I shake out the old charcoal and replace with the same amount of fresh charcoal.When I have to replace a filter, I line up the 1 inch slot with the flat retainer that hold the filter in the cap, this prevents the charcoal from floating out. You can also flush out any charcoal dust, before screwing on the cap.Since charcoal is cheaper, I have saved a lot and cats always have clean water

I've been using these water filters for several years now and am very pleased with them. Easy to use, effective filtering, and a reasonable price to boot. I have never encountered the "rust spots" that some reviewers have pointed out. I wonder if metal filings might have somehow gotten into the filter material during processing....maybe the manufacturer supplies different types of filters, some include metal, and some batches of base material got mixed up. Whatever the reason, I would have been appalled to find the rust as clearly it had to come from a metal source. Everything else in the unit is plastic. Looks like those incidents were a few years back so hopefully the problem was addressed and corrected. I replaced an old filter with one from the new package and it seems to be just fine....no rust and no errant pieces of charcoal...so far so good!

Keeps the water fresh and filtered
