Far UVC (222nm) Disinfection Solutions

222 Pure-Air™  Series

  • Kills 99.9% of all pathogens
  • Safe for occupied spaces
  • Fast, efficient and reliable disinfection
  • Chemical free disinfection process
  • Several mounting options
Praesidio  is proud to introduce the 222 Pure-Air ™ series from FORMOSA, our line of filtered 222nm Far UVC disinfection solutions for microbial reduction applications.

222 Pure-Air™ products can be safely used in unoccupied and occupied spaces without posing a health risk to humans when used within the current exposure limits recommended by the American Conference of Governmental Industrial Hygienists (ACGIH®) or the requirements of IEC 62471.

222 Pure-Air™ products contain highly efficient 222nm lamps and a filter that eliminates dangerous longer wavelengths of more than 230nm.

Safe, easy and efficient disinfection systems are now a reality.

Applications

With the 222 Pure-Air™ solution, organisations can take action to protect high traffic and high touch areas, thereby creating healthier working environments for all employees and visitors.

Hospitals,  Hotel Rooms,  Airports,  Meeting Rooms,  Schools,  Factory Floors

See the Scientific Research

It is well known within the medical sector that traditional UVC lighting is an efficient and thorough way of sanitising large rooms and surfaces within a medical setting. The reason that UVC lighting is not used as a sanitising solution for wider applications is because of the wavelength used. This wavelength (254nm) used in traditional UVC, whilst effective in killing viruses and bacteria, is also harmful to humans. This means that UVC lighting solutions can only be used away from humans, in pre-evacuated spaces. This is until now.

 

222 Pure-Air™ disinfection solutions harnesses all of the virus and bacteria killing efficacy of traditional UVC without being hazardous to humans. How does it do this? Traditional UVC solutions use wavelength 254nm, a wavelength which is harmful to the human skin and eyes. 222 Pure-Air™ uses a different wavelength of 222nm. This wavelength is still proficient at inactivating bacteria and viruses. However, it cannot penetrate the human skin or tear layer of the human eye.  See below for several research papers.
