PetSafe Drinkwell Fountain Premium Activated Carbon Filters - Better Hydration Choice - Long-Lasting Purity - Odor-Free Drinking - Water Purification Filter - 12 Pack

I order this product so often. It works perfect for our pet water dispenser. Thank so much the price is very good for us. Cindy

I have a boxer that adds more goo in the water than not. I had to clean his water bowl daily and the amount of slime on the bottom of his bowl was just plain gross! I bought a water fountain which these filters are used for. I’m pretty sure your supposed to change the filters every week. I have 4 dogs and probably should but I rinse mine the first week and then change it the second. The amount of goo in the bottom of the water bowl is minimal now. Yes dirt and some hair settles on the bottom of the bowl but the filter itself does a great job of helping with that nasty goo part. It does catch some dirt and hair also but like I said I have 4 pups. One likes to eat dirt (yeah she’s strange), one eats well lets just say other nasty stuff, and then there is Mr. Goo, and the last one has no issues. I’m not sure there is a water fountain or filter out there that would catch everything from my three pups! So overall the price is great, and the filters work to my satisfaction! I’d recommend them and will continue to use them.

Ok, so I clean my Drinkwell Platinum Fountain Drinkwell Platinum Pet Fountain 168oz and put the unit back on the floor. I lay down on the coach to take a nap. Next thing I know I have 3 paws whacking me upside the head and I hear, "Hello Mcfly, you did not change the dang filter and now the water is running over the top of the filter." So I get up and check out the filter. Low and behold the cats were correct. I did not change the filter and the water just ran over the top and went to the basin without being filtered. Now this was the 5th time in 6 weeks I had cleaned the unit. Basically it took 5-6 weeks for the filter to clog up. As the 3 amigos stared at me like I was a complete idiot I proceeded to replace the old filter with a new one from my stock I had purchased on Amazon. Once the new filter was in place, the 3 amigos all took their turns playing in the water, only pausing to give me the look of, "next time don't be such a dingbat," then proceeding to continue their frolicking. So here is the skinny on the filters. They really don't consist of much other than a fibrous trapezoid shaped to fit in your Drinkwell filter slot. They do have a black carbon side with some carbon granules between both sides that is supposed to remove odor from the water. How much odor it takes out I cannot say. But I am sure it does help. These filters will not take out anything that would be considered harmful like hard metals or even any minerals. They are not made for that purpose. They are made to keep things like hair or food particles from recirculating. And they function quite well for that purpose. Length of life simply depends on how many cats you have, how fast the filtration flow is, and how dirty your cats are. Over time I have noticed that my usage, with 3 playful kittehs, varies between 4-6 weeks. Now one of my cats thinks he is a raccoon. He is constantly taking his food over the water and cleaning it. Ok, he may just be playing with it, but he does take it over to the Drinkwell unit and puts the food in the water and then proceeds to bat it around. I also have another cat that likes to use his paws to bring the water from the waterfall to his mouth. For these reasons I tend to get a lot of cat hair in my fountain. Most is stopped by the hard plastic "pre-filter" but some does get by. This likely has an effect on my filters lifespan. I highly recommend these filters. As I have yet to find a generic brand for these filters you really don't have much of an option, unless you want to make your own. I make my own fish tank filters, but I have a basket/case made for the filtration materials to fit in. I have never seen anything like that for these filters. For that reason you really do not have much option other than using these, unless you want to somehow create your own basket to put your filtration media into. That being said, these filters do what they are intended to do. Watch for these to be on sale in bulk. I have found a 12 month supply (12 filters/4 - 3 packs) Drinkwell Platinum Premium Filters, 12-Pack for a good price at different times. The price does fluctuate so you have to watch it. Sometimes it is cheaper to purchase them just 1 package at a time and sometimes it is better to purchase them in bulk.

Filtered the water pretty well. But need to change them frequently.

Works well for the drinkwell water system. Great price. Highly recommend.

The filter helps the water stay fresh and clear of impurities for about two weeks at a time. I can tell it is working when I remove the old filter and there is a bit of a brown film on it. It's worth the money to keep my cat's water fresh and to keep me from having to change it more frequently. Very easy to place in the unit as well, and it fits perfectly in the allotted space and does not move around.

These work great.

I order these all the time for my cat's fountain. It helps keep their water cleaner even though I use filtered water in their fountain.
