With the Quiet Mark stamp of approval, this appliance will work discreetly without disrupting the tranquillity of your home. https://www.quietmark.com/about
The integrated air quality sensor continuously measures PM2.5 and VOC levels and displays them on a digital, touch-control panel. The panel’s easy-to-read LED icons also display the status of your air purifier’s Wi-Fi connection, operating speed and filter. When you download the Blueair Friend app and connect it to the Classic 280i, you can view your air quality and change settings from any smart device, whether at home, at work or at play.
Though small, the Classic 280i delivers solid performance with its compact fan design, large filter surface, and HEPASilent™ technology, which combines electrostatic and mechanical filtration technologies. This combination delivers a high Clean Air Delivery Rate (CADR) with whisper-silent operation and high energy efficiency. In fact, your Classic 280i works so quietly that you might have to check to make sure it’s switched on. And on its low setting, the Classic 280i uses about as little electricity as a lightbulb (20W).
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.
