A trial conducted earlier this year, in partnership between Hull University Teaching Hospitals NHS Trust and a Berkshire-based air hygiene company, has used electro-static air purifiers to capture 99.5% of airborne pollutants and viral particles up to 1.0 micron in size, which is where many harmful viruses exist, including Covid-19.
High precision air quality monitors were placed in Hull University Teaching Hospital’s Majors and Minor injuries area, where trial test results found that Evergen Air, the only ESP technology to be accredited by ISO 16890 in the world, reduced the amount of particulate matter 0-1microns by an average of 55% across both Majors and Minors clinical areas.
Traditional filtration involves trapping particles, where microorganisms that are not destroyed can often remain active and multiply. The Evergen Air systems, developed by one of the UK's fastest-growing green tech solutions companies, Evergen, uses electro-static precipitators to ionise pollutant particles and microorganisms, including bacteria, fungus and coronavirus particles within range, and this ability to neutralize and destroy harmful airborne pathogens signals an innovation for healthcare settings.
Chris Garner, Interim Director of Operations for the Emergency Medicine Health Group at the Trust, said: “We were really pleased to be chosen to participate in this trial and we’re grateful for the loan of the EvergenAir purifiers, whilst the testing has been underway”.
EarthSense, the air quality monitoring company that helped facilitate the trial, supplied their Zephyr air quality monitors to determine airborne pollutants levels before and after introducing Evergen’s cleaning system.
Following the successful trial, Hull University Teaching Hospitals NHS Trust is now installing the floor-standing EvergenAir units within their Ophthalmic Department.
