- Having 2 filter cartridges allows you sufficient time to clean the cartridge properly
- Allow the filter cartridge to dry after cleaning to improve filter effectiveness
- A quick source of hot water for your cleaning solution is the hot tub itself
- Rinsing with a garden hose or under a tap is sufficient; don't use a high pressure washer
- Rinsing the filter cartridge with water weekly is a good maintenance practice
Recommended monthly for hot tubs with moderate use.
- Prepare a solution of EZ Filter Nu and hot water (preferable) in a clean plastic pail, laundry tub or specific filter cleaning container
Remove the filter cartridge(s) from the filter housing and rinse with garden hose to remove physical debris
Submerse filter cartridge(s) in the solution and allow to soak for 6 – 12 hours
Once soaking is complete, remove filter cartridge from solution and rinse well with clean water from garden hose or tap - do not use high pressure washer
Allow the filter cartridge to stand until dry before putting back in use
Once cleaning is complete, the used cleaning solution can be safely disposed of by pouring down the drain.
