Wish there was a way to clean your pool's filtration system without pouring gallons of water into the environment? The SwimClear large-capacity cartridge filter delivers. No backwashing; instead, you just rinse the filter elements with your garden hose, saving you up to 2,500 gallons of water every season. Choose from 225, 325, 425 or 525 square feet of heavy-duty, dirt-holding capacity for extra-long cleaning cycles; this can translate to up to an entire season without cleaning. Another energy-efficient benefit is that the SwimClear doesn't require a multi-port valve, thereby using less electricity SwimClear filter tanks are created from new, stronger reinforced co-polymer for the ultimate in strength, durability and long life.
