OurAir SQ 1750 mobile room air purifier provides healthy and clean air for rooms up to 140 m². Several units can be used together for larger rooms. The pre-filter traps dust, lint, hair and other fibers. The individually tested H14 HEPA filter captures more than 99.995% of viruses, smoke particles, bacteria and other microorganisms down to .015 microns, making it able to deliver air quality equivalent to what you will find in hospital 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 cleans the air in a room up to 140 m2 by completely exchanging the air in the room 5 times/hour. It will provide medical-grade filtration by exchanging the air 12 times/hour in a room up to 60 m2.
The smaller the room, the more often the air is cleaned per hour and vice versa (see graph below).
