Our Patented Cyclonic Filtration System® uses the Water Diversion Blade® to drive water through the filter and keep it clean and fresh. The powerful main pumps are also used as low-speed circulation pumps that run in short intervals only when required. This reduces the number of components, lowers wear and tear, and consumes as little as one amp of electricity to reduce your energy costs. Additionally, because high temperatures and a wet environment can make an unprotected filter surface a target for the growth of bacteria, our filter surfaces are coated with Microban® antimicrobial protection. Microban® inhibits the growth of bacteria and reduces staining, odors and degradation of the filter surfaces. Microban® hot tub filters are also easier to clean, and stay fresher between cleanings.
