Air purifiers

Smart air purifiers thanks to environmental sensors

Experience the difference with our sensors

Ensuring optimal indoor air quality

Indoor air quality sensors enable accurate measurement of environmental parameters to monitor air quality and the condition of filters in use. An alarm is triggered if air pollution is too high.

Autonomous device control

Reliable measurements with environmental sensors enable automated operation of the air purifier. Depending on the level of air pollution, the air purifier can increase the air rate through the filter to provide cleaner air for the user.

Reduction of dust and pollen pollution

When the sensor system in the air purifier detects heavy fine dust and pollen load, the air purifier increases the air flow rate through the filter, immediately reducing air pollution and ensuring a healthy environment for the end user.

Increased energy efficiency

The indoor air quality sensors enable smart fan control that only switches on the air purifier when the detected air pollution requires it. Building occupants benefit from on-demand operation and minimizes power consumption.
