Disinfection without leaving residues using deep ultraviolet light.

The UV sterilization device FreshAir disinfects the air around the unit and the air sucked in by the fan through ultraviolet (UV-C) irradiation. The UV-C irradiation acts on the DNA of bacteria and viruses, rendering them inactive by losing their ability to reproduce. Sterilization using ultraviolet light does not produce resistant bacteria and is a clean method that does not generate harmful byproducts. Features of FreshAir: 1. 360° UV irradiation + fan for disinfection Not only does it provide 360° UV irradiation, but the fan also directly exposes the sucked-in air to the UV lamp for disinfection. 2. Ceiling-mounted design, so it doesn't get in the way It can be safely installed in spaces where there is no room for floor installation, in environments where children are running around, or where individuals with physical disabilities are present. 3. Can be used in occupied environments, with confirmed safety for living spaces Uses ozone-free lamps that generate little ozone. The ultraviolet light is also irradiated horizontally by a horizontal plate. A safety evaluation test based on JIS C 7550 was conducted by a third-party organization accredited with ISO 17025, confirming safety for living spaces, allowing for 24-hour use in occupied areas. *For more details, please contact us.
