My Protect air purifier is always detecting high levels of pollution (high PM or high tVOCs)

The Protect air purifiers have a built-in sensor to monitor the indoor air quality levels.

Particulate Matter (PM)* and Volatile Organic Compounds (VOCs)** 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 or gases.

Pollution from outside coming in from open windows or ventilation may also cause high PM levels.​

How to decrease the particulate matter (PM) and Volatile Organic Compounds (VOCs) levels and improve your indoor air quality?

  • Make sure that the air purifier is used in an adapted room size with closed windows and doors. ​
  • Set the highest speed of the air purifier temporarily or use the Auto Mode
  • Avoid excessive use of perfumed substances, cleaning products, or other VOC contributors​
  • Ventilate the room regularly and see if the PM and tVOC level lowers.
    • If the level of tVOC lowers when the windows are open and stay at the same level when windows are closed, then the device is detecting a gas that cannot be removed by the air purifier.
    • If the level of PM stays high even when you open the windows : ​Clean the sensors.on your air purifier. If the PM levels are constantly very high, there might be accumulated dust on the sensor giving a false indication.

Vacuum clean the air purifier from the outside at every filter change, especially around the sensors area (see picture)
*Examples of PM sources: candles, smoke, cooking, incense, fireplace, accumulated dust, unfiltered vacuum cleaner, pollen, pets, etc.
**Volatile organic compounds (VOCs) are gases and odors emitted from different chemicals. VOCs can be found within the air in your home; they are released by cleaning products, cosmetics, carpeting, furniture, air fresheners and many other consumer products.
