PetSafe Drinkwell Cat Water Fountain Filter Replacement - Carbon Replacement Filters, Pet Fountain Filters for Ceramic Water Fountains (12-Pack)

Exactly what i need for my fountain. I change my filter every 3-4 weeks and it lasts well.

Poor quality fake product filter , don't buy if U care about Ur pet.

These filters do their job and last a while before needing replacement. Only thing to watch out for is making sure you run them under water for a while before using them. The filters will work for the 1/2, 1, and 2 gallon water fountains made by PetSafe. Company also says it's compatible with their other fountains. When buying a pack of 12, they come in a small cardboard box but are individually plastic wrapped. The filters work as intended. A lot of grime that builds up over time from my two cats drinking water out of the fountain will collect on the filter. However, don't overestimate these either. They only work as well as the fountain can use them. I have the 1 gallon water fountain. I will still find small particulates at the bottom of the water. But I believe that is just the fountain not being able to cycle water with enough strength. Do they last 4 weeks like PetSafe claims? Maybe. If you remember to change out the water and clean the fountain each week, you might make a filter last 4 weeks. However, I do not do a full clean of the fountain each week. I usually do that at the 2-3 week mark. My filters average around 3 weeks this way, which is good enough for me. These are charcoal filters so it's normal to see black particulates when you first open them from the packaging. Rinsing is extremely important to prevent them from ending up in the water fountain. I run the filter under water for around 1 minute on both sides to make sure the loose charcoal gets washed out. If you do that, you shouldn't end up with any charcoal buildup in the fountain. Does the initial type of water used affect results? I believe it does. I've tested with regular tap from the faucet, filtered water from the fridge, and bottled water. When using regular tap water, I notice a lot more buildup on the insides of the fountain versus filtered/bottled water. I also feel that the filters last longer if you use cleaner water initially. Overall, for the price, these filters do their job. The minor complaints I have apply more to the fountain design than the actual filters themselves.

Son muy útiles, el agua se mantiene muy limpia.

Have tried multiple versions of this type of filter. These are by far the best. King lasting. Excellent quality. Will never try alternatives again!

If you use the fountain then you need these filters
