OurAir SQ 2500 is our largest portable air purification system that delivers virus-free, safe air in practically any indoor environment. Its individually-tested H14 HEPA filters capture more than 99.995% of viruses, bacteria and other micro-organisms to offer the same supply air purity as many cleanrooms.
Individually-tested HEPA filters1 capture >99.995% of viruses, bacteria and other micro-organisms.
Efficient motors and intelligent filter designs deliver high performance at a sound output of just < 30 – 40 dB(A)2
Powerful air flows clean more air, more quickly for improved safety and cleanliness.
Mobile plug-and-play solution for healthy and virus-free air.
Optimized system and filter media designs cut down on resistance and boost energy efficiency.
Filters can be replaced in minutes, and are easily accessible.
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.
Quick and homogene cleaning of the overall room - 99% particle reduction in 30 minutes
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).
