Far UVC (222nm) Disinfection Solutions
222 Pure-Air™ Series
- Chemical free disinfection process
- Several mounting options
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.
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.

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.
In the video below, Dr. Brenner of the Columbia University Medical Centre discusses the efficacy and safety of Far UVC 222nm wavelength. Properly utilised, it will be a huge step forward in controlling and minimising the transmission of Covid19 and also other harmful viruses, bacteria and pathogens.
Frequently Asked Questions
While higher wavelengths of UV light like UVA and UVB can be hazardous to human health, UVC 222 is safe for occupied indoor spaces and is still highly effective for inactivating viruses and bacteria. See the section on Scientific Research for further details.
UVC 222 is a light wavelength of 222nm that is safe for humans but effective at killing up to 99.9% of viruses and bacteria when sufficient exposure time is allowed.
There are several scientific papers that show the efficacy of Far-UVC 222nm. See the section on Scientific Research for details. In particular, Columbia University published its latest research in June 2020 showing that Far-UVC 222nm light can safely kill more than 99.9% of seasonal coronaviruses present in airborne droplets. The new paper builds on previous research.
While specific exposure times and distances may affect the speed of UVC 222 sanitization, 222 Pure-Air™ is always on, providing continuous passive protection at an impressive range.
222 Pure-Air™ solutions require no downtime and no harmful chemicals so they can help you save time and reduce the risk of accidental contamination for occupants and household pets.
The threshold limit value, or TLV, of 222nm ultraviolet light that a person can be exposed to per day has been set by the ACGIH (American Conference of Government Industrial Hygienists) and JIS Z 8812 (measuring Methods of Eye- hazardous Ultraviolet Radiation) at or below 22mJ/cm2 (up to 8 hours per day).
Use of the correct operating mode when installing and using 222 Pure-Air™ devices is important to ensure that exposure is within this limit. Ask for assistance.
