I have seen some reviews that say they are not of great quality but they work fine in in my standard drink well. They fit snug and work just like the original ones. I will be getting more so I can give my cats (7) fresh water. they last about a week since some of the cats like to put their heads under the water and drink it running off their faces. Weird but they like it and the filters fit and work the way they are suppose to. We also put an additive to the water for vitamins and minerals. Remember I have the stander Drink Well, not the large one the normal one.

Reading the reviews and seeing the photos, one is lead to believe that these filters are exactly like the Drinkwell original filters. Not so! They are cheaply made knockoffs that contain (maybe) half if the charcoal granules as the Drinkwell brand. If you could stack two of them together, they would approximate the thickness of the real ones. You will be changing these filters often because the don't do the job. I will use up these quickly and will go back to ordering the real ones.

GOOD QUALITY AT A FAIR PRICE. I'VE USED ONLY THIS BRAND OF FILTERS IN THE SIX YEARS I'VE GOT A NEW WATER FOUNTAIN FOR OUR TWO CATS. I HAVE NOT HAD ANY PROBLEMS WITH THE FILTERS. I WILL CONTINUE TO BUY THESE FILTERS. PERIOD

These filters don't actually fit our fountain, but the filters made for our Le Young fountain are awful. They disintegrate during use. Pet Standard are only slightly too long, but we can bend the frame to fit inside the water tower and stay clean while it fully filters the water without blackening the pump, parts, and water with the filter contents every single day. Pet Standard holds up well and is best when changed monthly. We have just one cat.

These replaceable filters are made to complement the watering system we purchased for our 3 pets. It does a wonderful job of filtering the water to remove any impurities in the water, whether they can be seen or not! Wow I am concerned about the particles in the water I can see, I am more important about this filter's ability to remove any impurities in the water that I cannot see. And it does a wonderful job at that. Depending on conditions and the number of pets, I would recommend replacing the filters every 2 to 4 weeks.
