Instead of injecting ozone into the spa water, as the ozonator does, the PureTech mixing chamber produces ozone in a separate chamber, which isolates the spa water and the ozone. This mixing chamber more effectively destroys bacteria that may be present in the water. The ozone-purified water is cycled back into the spa and more water is brought into the chamber. This cycle gradually brings all spa water through the mixing chamber for purification. This process greatly reduces the possibility of corrosion to the spa cover caused by ozone, as well as the odor that is sometimes caused by ozone that is injected into spa water. When the PureTech mixing chamber is used in conjunction with Nature2 technology, the spa water exceeds EPA’s standards for bottled drinking water.

Microfiltration removes contaminants such as dirt, metals and oil by passing the water through a microporus membrane. Larger particles are trapped in the upper layer, and smaller particles in the 1-5 micron size, are trapped in the lower part of the composite. The pleated filter has exceptional dirt-holding capacity and low-pressure drop. It retains its shape and is an excellent water filter. The polyester construction resists most chemicals.
