I cleaned the 511 as directed and changed the filters. The three top (circle) bars still light up red. Now that changes were made as directed and cleaned too why aren’t the three bars on top the color blue instead of red?
The three top bars on the Blueair Blue Pure 511 remain red after cleaning and changing the filters because the filter indicator has not been reset. After replacing the main filter, you must press the button for 15 seconds until the light turns white to reset the filter indicator.
