No single factor is more essential for hot tub or pool water quality than your filtration system. A soiled, clogged or worn-out spa filter will fail in its job of trapping contaminants. Old filters also put strain on your spa's pump and other equipment, which can waste energy dollars and reduce water circulation. Clean your filters with every water change and replace them annually to protect your warranty and reduce unnecessary service calls.
Rotate Filters -Keep Spares On Hand Use the filter rotation method: when cleaning your dirty filter, swap it with a clean dry spare. With this system you'll never have to wait to use your spa, and your filters will last longer. Allowing filters to dry completely after cleaning will help eliminate odors and resident microbes. Clean filters save energy.
