How Long Does it Take To Inactivate Virus And Bacteria In The Air And On Surfaces?

The speed at which wavelength 222nm can kill viruses and bacteria depends on a myriad of factors. Distance and wattage of the fixture use can have a bearing on the speed and the extent at which a wavelength of 222nm can eradicate bacteria and virus. In general, Based on the beta-HCoV-OC43 results, continuous far-UVC exposure in occupied public locations at the current regulatory exposure limit (~3 mJ/cm2/hour) would result in ~90% viral inactivation in ~8 minutes, 95% in ~11 minutes, 99% in ~16 minutes and 99.9% inactivation in ~25 minutes. Thus while staying within current regulatory dose limits, low-dose-rate far-UVC exposure can potentially safely provide a major reduction in the ambient level of airborne coronaviruses in occupied public locations.

How Can 222 Pure-Air™ Help In The Fight Against Covid19?

222 Pure-Air™ can help combat the spread of Covid19 in enclosed spaces in two primary ways.

1) 222-Pure Air™ kills 99.99% per cent of bacteria and viruses on surfaces in around 25 minutes when exposed to surfaces at a distance of around 2.5-3 metres. 222 Pure-Air™ does this without the use of chemicals and it continually kills new bacteria and viruses that generate within the vicinity of the fixture.

2) Coronavirus causing COVID-19, has a path to spread through aerosols that remain airborne for at least 3 hours after being expelled. This means, that even with the most covid compliant organisations and businesses, Covid19 may still spread between staff and customers through the air. The 222 Pure-Air light fixture kills airborne aerosols containing Covid19 within the vicinity of the lighting fixture and through strategic placement of 222 Pure-Air™ lighting fixtures, the risk of Covid19 airborne transmission could be brought to the absolute minimum.
