Several studies from the Karlsruhe Institute of Technology (KIT) confirmed that our room air purifiers OurAir TK 850 (predecessor of the SQ 1750) and OurAir SQ 2500 significantly reduce the number of particles in the room and thus contribute to reducing the risk of infection.

One device efficiently purifies the air in a room up to 200 m2 in size. Several units can be used together for larger rooms. Units can be stacked if desired or placed individually.

The smaller the room, the more often the air is cleaned per hour and vice versa (see graph below).
