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).
