This newly engineered RECT filter has been a massive topic of praise among our multi-cat clients. Unlike old-school loose carbon filters that tend to leak black residue into the basin, the upgraded solid "sintered" core keeps the tray immaculate. Hong Kong's municipal tap water carries heavy residual chlorine that can deter sensitive noses; this 4-stage setup heavily sweetens the taste. Our sitters always check these filters during visits, and seeing how much fine dust they capture from local urban environments proves how vital they are for preventing crystal formations.

ailor-made specifically for the Eversweet Max smart water fountain, this rectangular replacement filter features an upgraded food-grade "sintered activated carbon" structure. Compared to traditional loose carbon, its densely packed micropores offer superior absorption and enhanced durability. Utilizing a high-efficiency 4-stage deep filtration system (including high-density microporous cotton, sintered carbon, and powerful ion-exchange resin), it effectively intercepts floating hairs and dust while eliminating residual chlorine, odors, and heavy metals. By softening the water, it successfully lowers the risk of urinary crystals and stones in pet companions.
