About this product
Soak one of these cat water fountain filters for 5 minutes and rinse it for 30 seconds before it goes into the fountain. The pack holds 9 replacement filters and 9 replacement pre-filter sponges, sized for the PTM-643 fountain from Samrtoo. That fountain is a wireless stainless steel model holding 152oz/4.5L. Each filter carries five filtration layers, from activated carbon through to a high-density pump sponge.
Does it fit your fountain?
The filters and sponges are made for one fountain: the PTM-643 from Samrtoo, a wireless stainless steel model holding 152oz/4.5L. Check the model number of your fountain before ordering, since a different fountain is not covered by this fit.
Samrtoo asks buyers to take the official filters for the pet's health and the fountain's safety.

How the five filtration layers work
- Activated carbon makes up the first layer and removes bad taste and odour.
- Ion exchange resin forms the second layer and softens the tap water.
- Medical stone is the third layer, removing heavy metals and releasing trace elements.
- Non-woven fabric in the fourth layer filters hair and impurities.
- The high-density pump sponge is the fifth layer and helps remove fine particles.
The pack's colour is listed as silver, and the filters are intended for indoor use with house cats.
Soaking, rinsing and changing the filters
Before the first use, the filter needs 5 minutes in water and a 30-second rinse. The manufacturer recommends a new filter every 1 to 2 weeks to maintain the filtering effect. Where several pets are present, the filter needs changing and the fountain cleaning at shorter intervals.
