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.

OurAir SQ 1750

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).
