The air quality sensor is located on the back of your DustMagnet™ air purifier, just below the top filter drawer. Over time, dust can block the sensor and may interfere with air quality measurements. Clean the sensor periodically by following the directions below.
- Turn the air purifier OFF and unplug
- Use a vacuum to remove any visible dust on the outside of the sensor cover
- Pinch and lift the sensor cover to remove
- Gently clean the sensor with a clean, dry cotton swab
- Reattach the sensor cover and snap into place
- Plug the air purifier back in and turn ON
