How To Tell If a Blueair Air Purifier Filter Is Dirty?

Most Blueair purifiers say when to change filters using a little red light; when the sensor knows the filter has reached the limit of its use, it turns red. However, if the light is hard to see or not working, how can you tell? Some more subtle indicators include:

  • The air in your home is unimproved even if the air purifier is on for long periods.
  • The air purifier gets hot after some time.
  • It has been a long time since the filter was cleaned or changed.
  • The air purifier makes odd noises while in use.

If you are ever unsure, just open the air purifier according to manual instructions and inspect the filter yourself. If it is replaceable, replace it immediately. If it is washable, follow our tips above alongside manual instructions to clean it.

How Often Should You Clean Blueair Air Purifier Filter?

People often wonder with Blueair purifiers how often to change filters. While the brand suggests that most replaceable filters be changed every six months, this is an estimate. In truth, how often you need to change your filter comes down to a variety of factors, including the air quality in your area, how often you use your air purifier, how well you take care of it, and more.

Keep an eye on your sensor for a reliable indicator. In the meantime, wipe the top of the Blueair air purifier with a clean cloth and vacuum the pre-filter periodically. Once you switch Bluefilters, put a reminder in your calendar so you never miss a change date.

Can you leave the Blueair purifier on all the time?
