Air purifier improves employees' health

Using test-winning air purifiers in the office help improve air quality condition in the workplace and can help reduce the incidence of “Sick Building Syndrome” (SBS) symptoms, absenteeism and disease transmission that may lead to increased employee sick days and reduced productivity. A Harvard University study shares that air quality in offices has significant impacts on the employees’ cognitive abilities. 

Superior filtration technology

All Blueair air purifiers use the unique and proprietary HEPASilent™ technology.

A combination of electrostatic and mechanical filtration that provides maximum filtration with minimum noise and energy.

HEPASilent™ filtration technology


What makes Blueair air purifiers unique is the proprietary Blueair HEPASilent™ technology. By combining electrostatic and mechanical filtration, the HEPASilent™ technology ensures that a Blueair air purifier delivers maximum filtration with minimum noise and energy.

Typical HEPA filters: mechanical filtration only



Less clean air

A dense HEPA filter with very tiny holes captures particles, but this means less clean air passes through the filter.

More noise

To push enough air through a dense HEPA filter, the fan must run at a higher speed, which creates more noise.



More energy

Running the fan at a higher speed also uses more energy.



Removes viruses and bacteria

Mechanical (HEPA) filtration on its own catches virus and bacteria – but can allow germ growth in the filter as the germs are not inactivated.

Removes at least 99.97% of particles sized 0.3 micron

HEPA filtration catches 99.97% of particles sized 0.3 microns in size such as dust, pollen and smoke.

Blueair HEPASilent™ technology: electrostatic & mechanical filtration

More¹ clean air

By combining two filtration technologies the filter doesn’t need to do as much of the work, so Blueair filters can be less dense - which delivers a uniquely high flow of clean air.¹

Less noise

A less dense filter material means that the air purifier fan can run at lower speeds, making a lot less noise while delivering a uniquely high flow of clean air.¹

Less energy

Running at lower speeds also uses a lot less energy - less than a traditional lightbulb.¹



Kills viruses and bacteria²

Once captured in the filter, the combination of electrical charging and high air flow kills 99% of germs.

Removes at least 99.97% of particles sized 0.1 micron

HEPASilent technology catches 99.97% of particles down to 0.1 microns in size such as viruses, bacteria and microplastics, while also removing larger particles such dust, pollen, smoke and pet dander.

¹Based on tests of HEPASilent technology (mechanical + electrostatic filtration) vs. mechanical filtration alone, producing higher CADR (GB/T18801-2015), lower noise level (ISO3743), and lower energy consumption (GB/T18801-2015) in a standalone model.

²Tested on the filter media. Deactivation of germs on natural flora (excluding viruses) under normal temperature and humidity conditions. Blueair does not claim to kill SARS-CoV-2 or prevent transmission of COVID-19.
