Pro Maintenance Routine for Peak Efficiency Weekly Hose-Down: Pull the cylinder out and spray down the wide pleat channels with a garden hose to clear hair and surface sediment. Monthly Chemical Wash: Body oils build a blinding film on 3 oz. media. Soak the cartridge in a dedicated spa filter degreaser every 4 weeks to restore original porosity. The 12-Month Rule: Spa filtration media loses its electrostatic fine-particle attraction after a year of heavy sanitation use. Swap out your filter every 12 to 18 months to protect your heater tube and minimize pump strain.
