Unique Blueair HEPASilent™ Technology

The Classic 405 delivers high performance thanks to HEPASilent™ technology, which combines electrostatic and mechanical filtration technologies. This combination pioneered by Blueair delivers high Clean Air Delivery Rate (CADR) with whisper-silent operation and high energy efficiency. In fact, the Classic 405 works so quietly that you might have to check to make sure it’s switched on. And on its low setting, the Classic 405 uses about as much electricity as a light bulb.

The unique Blueair HEPASilent™ filtration technology also ensures that 99.97% of all airborne particles such as pollen, smoke, dust, mould, spores, bacteria, viruses, pet allergens and microplastics as small as 0.1 micron in size are removed from the air.
