Float tanks and open pools are typically equipped with several features to maintain water hygiene. A 10-micron filter bag, capable of filtering debris as small as one-fourth the diameter of a human hair, serves as the main filter. Additionally, water is pumped through a UV light array to eliminate microorganisms that may survive the extreme salt content (600 kg) of the water. After each session, the entire body of water cycles through a filtration system containing UV lamps and a micron filter 4-6 times. Various countries use products such as peroxide, bromide, or chlorine to control microorganisms, in accordance with their health regulations. Float centres also regularly test and balance the water throughout the day. The dense concentration of salt acts as a natural sterilizer, killing over 95% of microbes and bacteria. Moreover, unlike public swimming pools or hydrotherapy pools, users are required to shower and clean themselves before entering a float tank, further reducing the risk of infection.
