Why does the air purifier detect polluted air?
- The Blue Pure Max air purifiers have integrated particle sensors that can detect indoor air pollution level and display your air quality levels with the LED at the front of the unit in blue, amber and red.
- Particulate Matter (PM) peaks are normal and expected to happen temporarily, even when the air is of good quality because your air purifier’s sensors react each time the air purifier is in contact with airborne particles.
- Pollution from outside coming in from open windows or ventilation may also cause high PM levels.
- The levels of PM should decrease with the use of the air purifier and with ventilation.
Examples of PM sources: candles, smoke, cooking, incense, fireplace, accumulated dust, unfiltered vacuum cleaner, pollen, pets, etc.
How to decrease the particulate matter (PM) levels and improve your indoor air quality?
- Make sure that the air purifier is used in the recommended room size with closed windows and doors.
- Set the highest speed of the air purifier temporarily or use the Auto Mode to quickly improve the air ventilation in the room temporarily.
What to do if the air quality does not improve?
- Try to find the pollution source. If your air purifier has the Wi-Fi feature, the Blueair app can help find the pollution peaks. Open the Blueair app, add your air purifier and check the air quality history: check the indoor air quality peaks to see if it correlates to any air pollution inducing activty (cooking, lighting a candle, opening windows..etc)
- Test the air purifier in a smaller room. Place the air purifier in a small room running at the highest speed with all windows and doors (and ventilation if possible) closed.
- Clean the sensors. If the particle levels are constantly very high there might be accumulated dust on the sensor giving a false indication. Vacuum the outside of the air purifier, especially the air inlets, outlets, and the inlet for the air quality sensor. Power off the unit before vacuuming, see how to clean the sensors in the video below.
