Blueair’s HEPASilent™ technology uses a combination of electrostatic and mechanical filtration to capture and remove particles from the indoor air and should not be associated with air-cleaning techniques based on only ionization, or with systems using ozone to clean the air.
Our HEPASilent™ technology is unique in that it uses mechanical filtration to draw in polluted air into the air purifier and then specifically and strategically uses an ionizer to electrostatically charge particles inside the air purifier, allowing particles to better cling to the filter media in the unit, which in turn increases the air purifier’s filtration efficiency and overall performance. Blueair’s electrostatic charge technology is fundamentally different and should not be confused with technologies that use only ionization as a means of directly creating and releasing ions or ozone, because our technology also utilizes filter media to capture pollutants. An air ionization device, corona discharge or ozone generator air cleaners rely solely on techniques that produce and release ions into the space or uses ionization to intentionally emit ozone.
Our ozone emissions are rigorously tested to ensure they do not exceed any harmful levels.
All Blueair air purifiers conform to international and local ozone emission requirements in EU/CE, US/EPA & ARB, China/GB.
Blueair air purifiers have also been tested to reduce ozone in the air. Our ozone reduction tests have shown lower ozone concentrations in the air directly after passing through Blueair’s air purifiers and filters than the ozone concentrations in the surrounding air.
