'Ionair' was founded by Mr. Warner Fleischer who is the pioneer of ionization technology for air purification. 'Ionair' air purification system uses bi-polar ionization technology to provide both positive and negative ions for breaking down indoor TVOC and killing germs and viruses to ensure good, healthy in-door environment. The unique control system continuously monitors the in-door air conditions to regulate the +/- ions intensity. The +/- ions are generated by high voltage across the ionization tubes.

Unlike other low cost ionization tubes with short life time, 'Ionair' ionization tubes are manufactured by skillful Swiss craft out of supreme quality quartz which results in a long tube life as high as 10 years.
