Spa Filter Cartridges

Spa cartridge filters are designed for residential spas, providing efficient filtration with minimal water waste and straightforward maintenance. With proper care, most spa cartridge filters typically last 1–2 seasons, depending on bather load, body oils, water balance, and how regularly they are cleaned. To maintain performance and extend filter life, cartridges should be rinsed with a garden hose every 1–2 weeks to remove surface debris and oils, with weekly rinsing recommended for heavily used spas. A monthly deep clean helps remove built-up lotions, oils and fine particles, keeping the filter working effectively. Spray-on cleaners are useful for quick maintenance between deep cleans, while soaking cleaners are best for heavily soiled cartridges. Regular cleaning helps maintain clear water, supports healthy circulation, and reduces strain on spa pumps and heaters.
