See Air Differently at AHR AtmosAir's continuous air purifi cation technology makes the invisible visible for healthier air for all of your tenants, staff and guests. Not All Bi-polar Ionization Is the Same AtmosAir's dielectric barrier discharge (DBD) bi-polar ionization (BPI) technology is proven effective against bacteria, contaminants and viruses. Unlike competing BPI technology, AtmosAir's DBD technology remains active in the air longer by alternating the discharge of positive and negative ions to avoid recombination, which renders the ions less effective.
