My air purifier doesn't switch on
If your air purifier doesn’t switch on, try this:
Most Blueair models have a detachable plug that can slip out when you move the unit. Place the unit on its side and push the plug back into the socket at the bottom of the unit.
Make sure that the filter of your air purifier is correctly inserted and that the door of the air purifier is closed.
Unplug the unit from the electrical outlet and plug it back in again.-Plug the unit into another electrical outlet.
Check the power cord. If it is damaged in any way, unplug it immediately. Contact your local Blueair team to learn about getting a replacement or repair.
Make sure that you have selected a speed level to start cleaning the air.
If you are using a remote control, make sure that the battery is charged. If it isn’t, replace the battery.
If your air purifier still doesn't start, please contact the retailer where you bought the unit.
My device releases an unpleasant smell
First few times you use your air purifier
As with any new device, an air purifier can release a ’newness’ smell. Don't worry, this odor is not dangerous or toxic! Run your air purifier non-stop for a few days and the odor should dissipate.
For optimal use, keep the air purifier on at all times. It uses less energy than a low-energy light bulb.
Time to change the filter?
A dirty filter can release a dusty smell. Filters absorb odors from, for example, cooking. To avoid this, always replace the filter when indicated.
My air purifier makes an unexpected noise
Make sure that you have removed the plastic cover from the filter (not applicable to all models and filters).
Make sure that nothing blocks the air inlet and outlet.
Make sure that no object or dust is clogged around the filter. If there is, remove the filter and clean the purifier with a vacuum cleaner.
To remove the filter(s) to see if it is causing the noise:
Turn off your air purifier and unplug it.
Remove the filter(s).
Plug in the unit and turn it on. If the noise disappears, install a new filter. If the noise is still there, please contact the retailer where you bought the air purifier. They will help you according to their warranty conditions.
