  • From the air that passes through the filter, tested on the filter media for 1 pass efficiency at 5.33cm/s air flow, by a third-party lab.
  • 99.97% of pollution filtered from the air that passes though the filter.
  • From the air that passes through the filter, it is a theoretical time for one-time cleaning calculated by dividing its CADR 500m3/h by the room size of 48m3 (assuming the room is 20 m2 in floor area and 2.4m2 in height).
  • Microbial Reduction Rate Test conducted at Airmid Healthgroup Ltd. tested in a 28.5m3 test chamber contaminated with airborne influenza A(H1N1).
  • An air purifier by itself does not protect against Covid-19, but can be part of plan to protect yourself and your family to help ventilation and having clean air (US Environmental Protection Agency).
