• According to the United States Environmental Protection Agency (EPA), indoor air can be five times as polluted as outdoor air. Since indoor air is not circulated as much as outside air, many airborne pollutants continue to thrive inside.

•  CCDC recommends as part of a layered approach using portable high-efficiency particulate air (HEPA) fan/filtration systems to help enhance air cleaning (especially in higher risk areas such as a nurse’s office or areas frequently inhabited by persons with increased risk of getting COVID-19).

CDC recommends a layered strategy to reduce exposures to SARS-CoV-2, the virus that causes COVID-19

CDC - Ventilation interventions can help reduce the number of infectious viral particles (e.g., SARS-CoV-2) in the air.

Ventilation interventions include
opening windows, using fans, adding high-efficiency particulate air (HEPA) fan/filter systems, and adding upper-room ultraviolet
germicidal irradiation (UVGI). This factsheet presents information on upper-room

UVGI, which can be effective at reducing exposures to SARS-CoV-2 in some group settings

Coronavirus Stable for Hours to 3 Days on Surfaces The virus that causes coronavirus disease 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces, according to a new study from National Institutes of Health, CDC, UCLA and Princeton University scientists in The New England Journal of Medicine.
The scientists found that severe acute respiratory syndrome coronavirus
2 (SARS-CoV-2) was detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel. The results provide key information about the stability of SARS-CoV-2, which causes COVID-19 disease, and suggests that people may acquire the virus through the air and after touching contaminated objects. The study information was widely shared during the past two weeks after the researchers placed the contents on a preprint server to quickly share their data with colleagues.

Standard UVC is ultraviolet light with a wavelength of 250 nanometres. This high frequency wavelength light kills bacteria and viruses.

Standard UVC is ultraviolet light with a wavelength of 250 nanometres This high requency wavelength light kills bacteria and viruses and has been used extensively for more than 40 years in disinfecting drinking water, wastewater, air, hospitals, pharmaceutical products, and surfaces against a whole suite of human pathogens.

All bacteria and viruses tested to date (many hundreds over the years, including other
coronaviruses) respond to UV disinfection. Although, some organisms are more susceptible to UVC disinfection than others, all tested so far do respond at the appropriate doses.

While the UVC light is on, the area being disinfected needs to be clear of People, Plants, Pets. The area being disinfected should remain unoccupied a .....

Deep ultraviolet (UVC) light emitting diodes (LEDs) are an irradiation source and require due precautions to ensure safe usage.

Each year, more than two million people contract a hospital-acquired infection (HAI) that can also be antibiotic-resistant. These infections resulted in .....
