PET STANDARDPremium Water Filter Compatible with NPET® WF020 Water Fountain. Rectangular-Shaped, Washable Pet Fountain Filters with Triple Filtration System, Pack of 12

I have a pet waterer fountain that doesn’t seem to be manufactured anymore but needed replacement filters. These fit & work like the original filters. I am able to rinse & wash and reuse a few times before disposing. If you have a pet fountain be sure to read all product descriptions for construction as well as dimensions. My fountain requires a long narrow filter and these are perfect. I think these are well made and a good value if they are the correct size and design for your pet fountain

These are perfect. I do change my cats water every 3 days( 5 cats). And since we have well water, I use purified water in there water fountains. I wash these filters, swap them out as 1 set dries. Reuse a couple times before discarding. I do not think they need pitched as frequently as seller suggests as long as they aren't gross and u wash them out. Would not hestiate to purchase again as long as price does NOT increase...if it does, I will go back to making my own filters from aquarium substrate and activated carbon. More time consuming but will not pay for these if price increases..Hope my review helps.

We have pretty clean water here so we replace our cat's filter once a month (though we refresh the water daily while the coffee maker is doing it's thing). One package of these a year and we're done.These used to come in an obnoxiously large flat package but this year (at least) they come in a more reasonable stacked type obx so they store in less space. The individual wrappers keep the filters clean and flexible.

This are a fraction of the cost of the NPet brand filters. They do need to be changed a little more frequently than the brand name, but they are still effective and a good deal. I have two cats who get a lot of food residue in their fountain and their water gets cloudy. I have to replace the filter every week - rinsing and reusing does not work well. As long as I replace weekly, they work very well.

Decided to try these when I ran out. Good purchase. I will be purchasing again.

Essential, effective, provides clean drinking water longer.

Keeps my cats water pump, moving and clean

Fits as should
