Spa filters need to be washed off weekly. We suggest a filter wand as the most effective way of doing this without damaging the filter material.
On a bi-monthly basis you need to soak your filter in an approved filter cartridge cleaner solution to eliminate body fats and other organic matter that are not removed by simple rinsing.
Most people rotate 2 sets of spa filters so that they can soak one set while the other is in use. Adhere to the guidelines of your filter cartridge cleaner label.
Important: Purezone Filters cannot be washed and must be replaced at least every three months and sooner if spa is heavily used.
