¹ Test data shows our HEPA filter (brand new or like-new) can trap particles 0.3 microns in size at 99.97% efficiency. Research data shows True HEPA-rated filters can trap particles less than 0.1 microns in size at higher than 99% efficiency. For more info, see https://www.cdc.gov/niosh/docs/2003-136/pdfs/2003-136.pdf, pp.11–21.

² Zero ozone emission with the negative ion generator turned off. An amount of 0.002 ppm (parts-per-million) was recorded on the low fan speed with the negative ion generator turned on. That is 25 times less than the 0.05 ppm maximum ozone concentration safety standard set forth by the California Air Resource Board.

³ An amount of 0.001 ppm (parts-per-million) was recorded. That is 50 times less than the 0.05 ppm maximum ozone concentration safety standard set forth by the California Air Resource Board.
