Replacement Triple Action Fountain Filter Catit CH-7391, pack of 6, is a set of cartridge filters designed for use with compatible Catit pet water fountains. The multi-stage cartridges reduce hair and visible debris, help control odors and contribute to a cleaner tasting water for cats and small pets. Regular replacement of these cartridges helps maintain fountain flow and hygiene when used with the specified Catit fountain models.

Advantages

These triple action cartridges combine mechanical and chemical filtration in a single replaceable unit to capture hair and larger particles while reducing chlorine and improving water odor and taste. Supplied as a pack of six, the set reduces the frequency of repeated purchases and is sized for routine maintenance intervals. The cartridges are easy to install and remove, helping to keep fountain components clean and ensuring consistent water circulation.

Suitable for

• Owners of Catit fountains that require compatible triple action cartridges
• Homes with one or more cats or small pets that use a circulating water fountain
• Situations where regular cartridge replacement is needed to maintain water quality and pump performance

When it may not be suitable

This cartridge pack is intended specifically for compatible Catit fountain models; it may not fit non-compatible fountains or generic brands. If you require specialty filtration beyond hair removal and basic odor/taste improvement (for example, advanced chemical or biological contaminants), these cartridges are not designed to address those needs.
