The SwimPure Plus Electronic Chlorine Generator (also known as a salt chlorinator) is the largest selling system in the world. It automatically produces pure chlorine every day while the pool is being filtered and distributes it evenly throughout the pool via the return jets. The SwimPure Plus uses a low concentration of salt dissolved in the pool water (approximately one teaspoon per gallon) to produce up to 1.45 lbs of chlorine daily, enough to satisfy the sanitization needs of pools up to 40,000 gallons. It is also NSF certified and approved for use on commercial and public pools. SwimPure Plus easily installs on the standard filtration systems, both for new construction and on existing pools. SwimPure Plus comes equipped with an installation kit.
