My PM2.5 sensor has got 'stuck' on a very high number

Due to the function of the AirVisual air monitor's PM2.5 sensor, to constantly pull air and particulates through its sensor chamber, sometimes it is possible that a large particle, such as a piece of dust or similar, may enter the sensor chamber, and get stuck there. This can result in a very high AQI number (e.g. AQI 1358) or text notifications about cleaning your sensor being displayed on devices.

Fortunately, this problem is straightforward to fix.

To dislodge the particle, you simply need a can of compressed air, with a small spray valve. However, please turn off the monitor before using compressed air to clean it, to avoid any possible damage to the fan inside the sensor.

You could also use a hairdryer that can blow cold wind, but there's a risk of damaging the sensor if not used properly. You can then direct the compressed air toward the PM2.5 sensor, and spray for a couple of seconds.

For AVP, you can access the PM2.5 sensor through the little gap in the middle hollow of the monitor, on the device's front side.

Cleaning the PM2.5 sensor through the little gap of the monitor

For AVO, you have to move it from the wall first and then access the PM2.5 sensor through the air inlet cover.

Cleaning the AirVisual monitor

You should see your monitor's readings return to normal, once the particle is dislodged.
