  • What data does the air purifier measure? (PM 2.5, PM 1, PM 10, TVOC, humidity, temperature)

Applies to

  • AEG AX9 series air purifiers

  • AEG AX7, AX5 series air purifiers

  • PURE 700 / 7000 series air purifiers


Depending on the model purchased, you might have one or more sensors than what is described below. 

As a standard, the WELL AX7/AX5 series and PURE 7000 series air purifiers come with an advanced laser PM sensor (Particulate Matter). This sensor can measure the following: PM10, PM2.5 and PM1.

PM 2.5 are inhalable fine particles 2.5 μm (micrometre) or less in diameter that are potentially small enough to penetrate the bloodstream and impair immune response. PM 2.5 may include combustion particles, organic compounds and metal emissions.

PM 1 are inhalable ultrafine particles 1 μm (micrometre) or less in diameter that are small enough to penetrate the bloodstream and reduce the oxygen-carrying capacity of the blood. PM 1 can remain in the air for days or weeks. 

PM 10 are inhalable coarse particles 10 μm (micrometre) or less in diameter that can inflame airways and lungs. PM10 may include dust, pollen and mould.

In addition, some Well AX7 also come equipped with a volatile organic compound (VOC) sensor, a temperature sensor as well as a humidity sensor - the measurement data from all of these sensors is available to view and track in the AEG App.

Total Volatile Organic Compounds (TVOC) are emitted gases from certain solids or liquids, including a variety of chemicals, that can accumulate in your home. Not all VOCs are harmful, many VOCs are relatively benign. For example, oranges and coffee beans emit VOCs.

Reduce VOCs in your home by opening windows or doors to allow air to circulate as well as reducing or removing products that bring VOCs into your home.

To get a more accurate reading, open a window to expose your air purifier to fresh air every once in a while. The TVOC sensor will self-calibrate every 24 hours or so. While recalibrating, TVOC data can be inaccurate or fluctuate

Humidity is the amount of water vapour in the air. Bacteria, moulds, mildew and viruses can be reduced by keeping humidity between 30-50%

Your air purifier can tell you how humid the air is but does not control humidity.

Temperature refers to how hot or cold the air around your purifier is. For anyone with respiratory problems or allergies, the World Health Organization recommends a room temperature of no less than 16°C (61°F) and for the sick, disabled, very old or very young, a minimum of 20°C (68°F).

Your air purifier can tell you the temperature, but it does not control the temperature.
