Catit PIXI Fountain Filter Cartridges have a triple action filter for clean drinking water. The filters help eliminate odours from drinking water too thanks to the active carbon in each filter.
The triple action filter works in three ways:
1. The cotton mesh removes hair, sediment, and debris (including food)
2. Active carbon removes odour and impurities
3. Ion exchange resin helps soften tap water by filtering out excess calcium and magnesium which can help prevent urinary tract disease
