Did you know the number one reason for hot tub freeze damage is a dirty filter? Dirty filters also cause additional stress on the pump/motor and leads to premature failure.
Proper Filter Care System:
- Have 2 sets of filters
- Install clean filter
- Rinse dirty filter with high pressure nozzle
- Verify no debris left between pleats, before storing on shelf to dry
- Once a month soak filters in a filter cleaner solution
