PK.ZTopia 8-Pack Cat Water Fountain Filter, Pet Fountain Filters, Replacement Filters for 84oz/2.5L Automatic Pet Fountain Cat Water Fountain Dog Water Dispenser

Great product that is cheaper than the orginal brand.

I use a Veken Brand pet water fountain. The filter element matches it very well ，Based on what I see on the filter when I clean the fountain, they appear to be doing a fine job.

Super easy to use. Will be reordering.

Great 4 fountains

They work well
