About this product
This cat water fountain filter pack holds four replacement filters, each measuring 11.4 x 4.6 x 2 cm and weighing 100 g across the set. NPET makes them for its WF050, WF100 and WF210 fountains, so the fit depends on which model stands on your floor. Each filter runs water through five stages, from a non-woven fabric layer to a medical stone layer.
Cleaning the sponge and changing the filter
That schedule covers the whole five-stage block, not just the outer fabric, so a filter that has been in place for a month is due for replacement.
Does this filter fit your NPET fountain?
Check the model name on the fountain body before ordering: the filters are made for the WF050, WF100 and WF210. A fountain from another NPET series is not covered by this pack. The filter measures 11.4 x 4.6 x 2 cm (4.5 x 1.8 x 0.8 in), which is the size of the slot it drops into, and the pump sponge sits in the pump housing. Both parts are white polyester, so a coloured or differently shaped filter housing points to a different model.
What arrives in the box
- Four packs of replacement fountain filters
- Four packs of replacement pump sponges
- Each filter and each sponge wrapped on its own
How the five stages work in the fountain
Water passes a non-woven fabric layer first, then a high-density sponge that holds back debris. An activated carbon stage takes odours out of the water, and an ion exchange resin stage softens hard tap water. The last stage is medical stone, which removes heavy metals.
The filters are built for quick installation into NPET pet water fountains. The individually wrapped filters and sponges keep the spare parts dry until a swap is due.
