What are the benefits of Carefree Clearwater?
The Carefree Clearwater systems based on NASA’s Apollo-era technology electronically release copper and silver ions into the water to destroy bacteria and algae —which are then filtered out. Unlike chlorine, the ions do not dissipate from heat and sunlight, therefore they are capable of providing a very stable sanitizer residual. The ionization technology substantially reduces the demand for chlorine so that fewer chloramines are formed and fewer chemicals are consumed. This cuts down on undesirable side effects realized in swimming pool environments, such as burning eyes, odor, and bleached or dry skin and hair. Furthermore, the ions pose no health risks, as scientists contend that chlorine can react chemically with organic materials in water to form a class of carcinogenic substances called trihalomethanes.
