Maintenance Tips
- Rinse the cartridge regularly (weekly for heavy use) to prevent restriction and keep jets flowing strong.
- Deep clean every 3–6 weeks (or as needed) with a cartridge cleaner to remove oils; rinse thoroughly before reinstalling.
- If scale is present, degrease first, then use a scale remover; rinse completely before returning the filter to service.
- Consider rotating between two cartridges (one in use, one drying after cleaning) to extend service life and improve performance.
