Kills What Chlorine Can’t Whether you use a salt system or chlorine to disinfect your water, there are dozens of pathogens like E. coli that are resistant to regular disinfection. But when pool or spa water passes through the low-cost, high intensity NUVO Sterilization Chamber, these pathogens are eliminated by the same process used to sterilize surgical instruments. The result is safer, cleaner water for only pennies a month. Plumbing connectors are included. NUVO uses the highest quality quartz and has no moving parts for performance and long life.
