SwimClear single element cartridge filters capture more dirt for superior water clarity without the need of supplemental media or backwashing, while the industry's lowest head loss reduces energy costs. SwimClear is also the easiest to service: the Easy-Lok™ ring design, comfort grip handles, and lowest lift height provide fast cleaning and element replacement. SwimClear is an excellent filtration solution for smaller and mid-size pools, spas and water features.
