NPET Upgraded Design 4 Pack Replacement Filters for WF050/WF100 Cat Fountain and WF210 Stainless Steel Pet Water Dispenser

Works well, first fountain perfectly. Needs replacing more frequently than expected which doesn’t make it cost effective

I used up the filter and sponge that came with the fountain, and I saw these. They look the same, they fit perfectly, and they have been working very well in my machine. It's easy to pour the water in but I can tell it's filtering well too. It was very easy to place the sponge in the filter motor piece and the main filter in it's spot. Just fit right in there, no fussing. I did run water through it first to "prime" the filter, and I haven't found any debris or carbon pieces in the water or lower basin. The fountain pumps quietly and well, just like it was new. A great way to have these for 4 months supply! I'll stick with this brand for them!

They are exactly what I needed... perfect...will buy again

Good for a price.

Work well in pet fountain. Long lasting.

It’s pretty easy to set up, use and clean. We recently bought a second one. Our first lasted 4+ years being constantly on and somewhat abused (ran low/dry several times, unintentionally). We were sad when the first finally gave out but immediately bought another.

Perfect fit!

So much better than other brands. Keeps water fresher than other brands and love it comes with a new sponge for the motor every new filter
