The main function of the oxygen ionizer is to purify the air and kill odor causing bacteria. Inside a sauna, keeping the air fresh is critical because of the heat and perspiration. Without purifying the air inside the sauna after usage, the sauna can get stuffy and smells bad.
The Ozone cannot sustain its form in normal enviroment and will break a few seconds after it generates. Ions option will allow the ionizer to capture bacteria and impurities inside the Ionizer.
When you start to pre-heat the sauna, turn the ionizer on. In 15 minutes the ionizer will switch automatically to Ion, wait a few minutes and start using the sauna. Keep the ionizer in Ion while using the sauna.
Remember, keeping your sauna clean is important and the oxygen ionizer will help purify and clean the air in the sauna. If the sauna gets stuffy, open the roof vent or the door.
