Indoor Air Quality
Comparative Technology Assessment White-paper
There is an acute focus by government and health institutions globally, such as the WHO and the CDC, on good quality air to improve indoor ventilation and in particular, to reduce exposure to airborne pathogens like SARS-CoV-2.
If a person with COVID-19 is in a room, infectious virus particles will move around the space, infecting others particularly where indoor air is being recirculated. Similarly, ventilation in one room may carry infectious viruses into connected rooms through HVAC vents that serve multiple rooms – common in schools, hospitals and office buildings.
And that’s where virucidal filtration comes in.
Learning how to clean the air of potentially virus-laden aerosols would have long-term benefits for health and allow businesses and schools to remain open during future outbreaks and enable safe travel.
Clean Air – choosing the right solution
There are a lot of companies that claim their technology provides covid-killing solutions for homes and buildings – choosing the right solution can be bewildering and complex, so here we set out the main technologies that exist, how they work, and break down the facts. For more detail please refer to the EPA summary of air cleaners.
Our white-paper compares the effectiveness of:
- UVC – Ultraviolet Light
- Ionizers/Ozone generators/Electostacic precipitation (ESP)
- Spray-based/surface disinfectants
- GC Ink Coated Filters
