Care & Maintenance
After you upgrade to Excel Filters we recommend cleaning your new filter cartridges after an initial pass. Because Excel Filters are so effective they'll remove debris left behind by your previous cartridges
Excel Filters are easy to clean. We recommend filter rotation – while cleaning your filter cartridges, swap them with clean, dry spares. This keeps the water filtration cycle going and no wait to use your pool or spa with the added benefit of your filter cartridges lasting longer.
