You can check the indoor air quality in real time by using the indoor air quality indicator.

The indoor air quality is displayed based on the density of fine particles and VOC density 
being sensed by the unit.

 IAQ indicator may not react to some particles and its readings may 
be different from that of other air quality measuring products and 
instruments.
