Based on testing of SARS-CoV-2 conducted in laboratory conditions using a 13 cubic foot chamber to protect scientists from exposure. Not proven to prevent COVID-19. Performance was measured after 10 air exchanges passing through the air purifier operating at its minimum fan speed and with plasma ion technology on. Actual results may vary depending on usage environment (temperature humidity room size and shape nature and number of particulates in air etc.) placement of the unit and product usage (operation duration operation mode etc.). Best results with continuous use. Performance claims are calculated based on testing of a single particulate A. Niger (mold) E. Coli (bacteria) S. Epidermidis (bacteria) or Phi-X174 (virus) under laboratory conditions following 1 hour of air purifier operation at the maximum fan speed and with plasma ion technology on. Actual results may vary depending on usage environment (temperature humidity room size and shape nature and number of particulates in air etc.) placement of the unit and product usage (operation duration operation mode etc.). Best results with continuous use. Sensors have a margin of error of +/- 20 micrograms per cubic meter in detecting changes in air quality. Based on industry standards for removing 99.97% of ultrafine particles (0.3 microns) from the air in a room 5x per hour. Efficacy in removing viruses and bacteria is reduced.
