Frequently Asked Questions
-
The best method combines regular rinsing with periodic deep cleaning. Rinse weekly with a hose or filter wand, then deep clean every 4-6 weeks by soaking in Hot Tub Things® Cartridge Cleaner for 8-12 hours to remove oils and mineral deposits.
-
While vinegar can help with mineral deposits, it's not effective at removing body oils, lotions, and organic debris. A dedicated filter cleaner like Hot Tub Things® Cartridge Cleaner provides superior cleaning and is specifically formulated for spa filters.
-
Remove the filter, rinse off loose debris, then soak it in a filter cleaning solution for 8-12 hours. Rinse thoroughly until water runs clear, allow to dry if possible, and reinstall. Deep clean every 4-6 weeks for optimal performance.
-
Regular cleaning extends filter life significantly. Clean your filter every 4-6 weeks and replace it every 12-24 months, or sooner if pleats are damaged, brittle, or cleaning no longer restores performance.
-
Rapid filter soiling indicates high bather load, inadequate water chemistry, body oils and lotions, or an undersized filter. Shower before entering, maintain proper chemistry, and consider adding a mineral cartridge to reduce contaminant load.
-
Never use dish soap, laundry detergent, or household cleaners on spa filters. These products leave residues that cause excessive foaming and can permanently damage filter media. Always use a dedicated spa filter cleaner.
