The air cleaners are equipped with HEPA 14 filters and clean the indoor air five to six times per hour, compared to the regular ventilation system which replaces the air in the room about two times per hour. Each air cycle that passes through the HEPA 14 filter reduces particle levels by 99.995%. This includes virus particles, bacteria or other particles. A new report on respiratory viruses published by the University of Gothenburg shows that the coronavirus is largely airborne, and that poor ventilation increases the risk of infection.
– “The report gives us confirmation that we acted correctly during the pandemic in our efforts to combat airborne infection” Peter Ryd continues. “Air cleaners, coupled with primary protective aids, good hygiene practices and personal protective equipment, have given healthcare staff an extra source of protection in their working environment”.
During periods with a reduced need for COVID-19 wards, the air cleaners have been used to reduce airborne particles in i.a. waiting rooms, staff rooms and medicine storage rooms. Now, Peter Ryd works with one of the hospital’s chief physicians, an expert on air cleaning in operating rooms and an infectious disease physician to prepare a set of guidelines with recommended uses for air cleaning in healthcare.
