Introduction: How to Clean Hot Tub Filters
How to clean hot tub filters
Replacement hot tub filters are expensive so extending the life of the ones you have is very worthwhile. Using this method I haven't needed to change mine for a few years. You need nothing more than a hose pipe, a bucket and some chemicals (which you will have anyway).
Filter manufacturers would say you should renew jacuzzi filters regularly but they would say that wouldn't they.
This may not be the best way to clean hot tub filters or the only way but it works.
