Choose Which Generation Model You Have

Filters: Many filters are patented design. The most common one has a twist off handle that allow you to add their ProClear or chemical dispenser.  

Somei also offer filters with Microban in the paper. Microban is used to limit organic growth on the filter. It lasts the life of the filter.

We recommend cleaning the filters every 3 months and replacing every 1-2 years. If you have a model with a 24/7 circulation pump, I recommend you clean the filters more often OR switch filters after 1 1/2 months. My concern is if the filter is not clean, it could affect the longevity of the circulation pump.

Cleaning filters must include a method of "emulsifying" the oil on the paper. Bleach will not do it. Hot water will not. Most use either TSP or a filter cleaner. But you must breakdown the oil and rinse throughly. Otherwise it will clog and cause flow problems and damage.
