FAQs

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.

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.

You can find instructions for the filter replacement timer in the user manual provided with your unit. All user manuals are available online under our Customer Support section.

Blueair recommends a filter change every six months. The light on your filter timer will indicate when it is time to replace your filter after six months of continual use.

If you use your unit in a highly polluted environment, you need to change it more often. To ensure the unit’s high-quality performance, we recommend that you only use genuine Blueair filters.

Blueair filters cannot be cleaned or washed. They need to be replaced every 6 months. Please check your user manual to see replacement indications for your model. All user manuals can be found in our Customer Support section.

Blueair pre-filters can be vacuumed or cleaned with your laundry (30 or 40 degrees maximum). The pre-filter is the colored textile filter that you place on the outside of your unit (only available for the Blue Pure series).
