FAQ - a frequently asked question about the meter is:

Pollutants spread through a room at different speeds. The regulations for smoke detectors in Germany stipulate the following: To ensure a sufficiently high reaction speed to occurring gases, one warning detector / smoke detector / air sensor should be installed per room of 60 square meters (with a normal ceiling height of approx. 2.8-3.2 m). In L-shaped rooms, several measuring devices should be installed - one device on each side.

However, in non-critical areas where the air quality is to be monitored in general, the regulations for smoke detectors do not apply. We recommend installing one air-Q for every 60 - 140 square meters. If air-Qs are mounted on the walls, 60 square meters are preferable; if they are installed in the middle of the room, one air-Q every 140 square meters is sufficient to obtain a sufficiently accurate picture of the air quality.
