What are hydroxyls?

Hydroxyls (OH) are safe, naturally occurring molecules which quickly react with and destroy volatile compounds, includes viruses and bacteria. Created in our atmosphere when the sun’s ultraviolet rays react with water vapour, they play a critical role in cleaning the earth’s atmosphere and are often referred to as the “detergent” of the atmosphere.

Through the use of proprietary UV technology, OHAir replicates the natural production of hydroxyls to actively eliminate biological and chemical contaminants.
