The AAF HEPA Filtration System allows you to take control of the purity of the air you breathe and provide a location where people can remain safe until an airborne threat subsides.

The system creates an enclosed space under positive pressure, meaning that no contaminated air can enter the protected space, because the air pressure in the space is greater than the air pressure outside the room. The only air entering the enclosed space is filtered through hospital-grade HEPA Filtration Systems which are greater than 99.99% effective against 0.3 micron particles.

HEPA Filtration Systems can be adapted to single areas, multiple floors, or a designated number of occupants to meet the needs of any facility: schools, hospitals, public buildings, office or other commercial buildings. The ceiling-mounted HFS is designed to insert into standard suspended ceilings, and can be easily installed in one day by most HVAC contractors.
