What is an Automatic Water Purification System?
An important aspect to consider when selecting a hot tub is the method of water purification that you plan on using. Spas need chemical sanitizers such as chlorine or bromine, just like swimming pools, in order to keep the water clean. A supplement to chemical sanitizers are water purification systems that are built into the spa. These systems automatically sanitize your water, often enabling you to greatly reduce the amount of chemicals needed for water purification. Ozone Ozone is produced on-site of the spa by a special ozone generating unit. Ozone generators can be categorized as either ultra-violet (UV) light or corona discharge (CD) ozone systems. The current trend in the spa industry is toward CD systems. Not all CD systems are created equal. Most CD systems use a chip that must be replaced periodically, as it looses ozone output efficiency over time.
