A spa filter is something indispensable in every swimming pool. They also have to be properly maintained, perfectly and correctly sized to the pump. Spa filters perspiration, body oils combined with soaps, body lotions, organic matter like algae and other chemicals that may clog the filter. In order to maximize the life of a spa filter, proper cleaning should be done regularly as maintenance. Stiff brush should never be use to scrub the media and also pool owners like us should maintain the pool or spa water chemistry in proper balance.
