Why Is My Blueair Purifier Not Working?

There are various reasons why your Blueair purifier might not be working.Here are 9 of the most common reasons:

1. The Purifier Is Not Getting Enough Power:

Ensure that the outlet is at least 15 amps and that the air purifier is not connected to other devices simultaneously.

If, for instance, you are using an outlet on which you have other devices plugged in, your air purifier may not be getting enough power. And this could be the reason why your air purifier isn’t working.

2. Issues With The Power Cord:

Perhaps the power cord is not plugged correctly into the air purifier or the outlet.

  • Make sure that both ends of the power cord are plugged in correctly.
  • The power cord could also be damaged. If you see any fraying or damage to the power cord, unplug it and buy a new one or contact Blueair customer service for a replacement.

3. A Blown Fuse:

If your air purifier has blown a fuse, this could be the reason why it isn’t working.

To check if this is the case, locate the fuse on the back of the unit and remove it. If the fuse is blown, you will need to replace it with a new one.

4. A Tripped Circuit Breaker:

If your air purifier is plugged into a wall outlet, there could be a problem with the circuit breaker.

  • Check your main electrical panel and reset the breaker for that outlet.
  • On the other hand, if the outlet reads GFCI (Groundfault circuit Interrupter), an orange light shows on it. This orange light means that the outlet needs to be reset. So, press the reset button, and it should start working.

5. Improperly Installed Filters

Check the air purifier filters and Ensure you have installed them according to the instructions in the user manual.

6. Obstructions/Blockages

It is possible to have an obstruction or blockage somewhere in the unit. Check the air intake and exhaust vents to ensure nothing is blocking them.

7. Problems With The Wall Socket

  • Your wall outlet could be the problem. To test if the outlet is working, plug something else into it.
  • If that doesn’t work, try to reset the breaker box and test the outlet again. If the outlet still doesn’t work, you will need to have it repaired or replaced.

8. Dead Batteries In Remote Control

Sometimes batteries are dead and need to be replaced with new ones.But, in other instances, they could be installed wrong.

  • check the batteries to see if they are aligned correctly, positive with positive and negative with negative (+/-).
  • If you have a rechargeable remote make sure it’s properly charged.

Perhaps there is an issue with the motor or other internal electrical components.If this is the case, you must take your air purifier to a Blueair service center or contact customer service for assistance.
