❶
Powerful disinfection and de-odorization
Hydroxyl radicals generated by chemical reaction which is harmless provides a unique solution of
disinfecting actively the air and space surfaces as well by removing, in actual coverage of indoor
living, harmful bacteria, viruses, fungi, odor, VOCs and so forth.
❷
Constant level of high air quality
Indoor pollutants are generated from indoor life itself and are constantly supplied from outside. So,
we need to remove it continuously. Wellisair air purifier has been developed to meet this
requirement to operate 24hrs a day. We recommend 24hrs-a-day working of the device for
much higher air quality in your space.

international laboratories and universities. Field trials have also been carried out in hospitals,
schools, veterinary clinics...
❹

By replacing cartridge every three months, it provides constant high level of air purification. Power
consumption is also low so that monthly charge does not exceed $1. No need to buy and change
filters or UV ramps.
