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.
Supplements 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.
