About the Device

OurAir SQ 500 is a compact, yet powerful portable air purification system that delivers virus-free, safe air in a smaller indoor environment. Its individually-tested HEPA filters capture more than 99.995% of viruses, bacteria, and other microorganisms to offer the same supply of air purity as many cleanrooms.

OurAir SQ 500 has been designed to provide virus-free air in smaller spaces - such as home offices and hotel rooms.
