Airborne microorganisms such as viruses, bacteria, yeasts and mildew are especially present in heavily frequented areas such as airports, medical practices and the industry.
They jeopardise the health of persons, contaminate raw materials and cause food to perish.
UV radiation reliably reduces the germ load and improves hygiene and storage conditions.
To reduce the germ count in the long term, the germ-infested air can be disinfected already in the supply air ducts.
In particular short-wave UV radiation has a strong bactericidal effect. It is absorbed by the microorganisms' DNA and destroys its structure. This inactivates the living cells.
