The 400 Series Particle Filter is designed to fit the 402, 403, 410, 450E, and 455EB.
The filter should be changed every six months, or 188 days, to keep your Blueair unit working at its highest efficiency. In ECO10 units, the filter should be changed once a year.
Your magnetic filter timer will keep track of when your filter needs to be changed; its LED light will flash to notify you every six months or 188 days.
The filter timer built into your electronic unit will flash an LED light to indicate when it needs to be changed.
To reset the magnetic filter timer, press and hold the “RESET” button for 10 second. The filter change indicator light will turn off and the counter will begin its countdown to the next filter change(188 days). To temporarily stop the filter indicator light for five days, press the “SNOOZE” button.
To reset the filter replacement indicator on an ‘E’ series unit, press and hold the “TIMER” button for 5 seconds. The filter change indicator light will turn off and the counter will begin its countdown to the next filter change(188 days).
Yes, absolutely. Our filters use patented HEPASilent® technology to trap 99.97% of airborne bacteria particles down to .01 micron. The combination of mechanical and active electrostatic filtration provides an exceptionally high level of protection against airborne bacteria and ensures bacteria particles are never released back into the air.

To change the filter in your 400 series unit, open up the front door of the unit with the Blueair logo on it. You will find the filter placed sideways inside the unit. Slide out the old filter and replace it with the new one. The new filter should be facing you, so that you can read “This side must face front”. Make sure the door is securely closer, or else the unit will not start.
