General Tips

• Always wear rubber gloves when handling your filter cartridge
• 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

Cleaning Process

Recommended monthly for hot tubs with moderate use.

1. Prepare a solution of EZ Filter Nu and hot water (preferable) in a clean plastic pail, laundry tub or specific filter cleaning container
• Lightly used hot tub – use 200 mL of EZ Filter Nu for minimum 6 hours
• Moderately used hot tub – use 300 mL of EZ Filter Nu for minimum 6 hours
• Heavily used hot tub – use 400 mL of EZ Filter Nu for minimum 12 hours
2. Remove the filter cartridge(s) from the filter housing and rinse with garden hose to remove physical debris
3. Submerse filter cartridge(s) in the solution and allow to soak for 6 – 12 hours
4. 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
5. Allow the filter cartridge to stand until dry before putting back in use
6. Once cleaning is complete, the used cleaning solution can be safely disposed of by pouring down the drain.
