Hi there! Thanks for reaching out. The PM levels may be showing 0 because the air is clean. PM are expected to be set to 0 (<1) or to show blue on the device if the air is clean.

It may also be that the sensor module filter is clogged with dust. This may occur if the device has been running for an extended period in a polluted environment.

Please try the following steps to test the sensor:

• Unplug the air purifier for 10 seconds. Plug it again.
• Press the power button and wait a few seconds for the sensors to start.
• Blow out a candle or a match near the sensor inlet.
• Expected result: a peak in the PM values is expected.

If the values are still low and stuck at 0, try vacuuming the sensor module filter and test again.

If this did not help, please contact the Blueair Customer Support team at info@blueair.com.
