The key is maintenance.
It is vital your filter cartridge is maintained correctly to maximize its life and usefulness. The life of a filter cartridge depends on how you treat it. Filters need to be cleaned and how often depends on how often you use your spa. We advise that you clean your filter at least every two months. Filter clogging is caused by soaps, chemicals, perspiration, body fats, oils and fine particles of dust or dirt. A blocked spa filter cartridge can put undue pressure on your pump and motor and decrease the life of these parts.
Take away: You can save money, reduce the wear and tear on your spa while prolonging the life of your filter with a few basic maintenance steps.
