AJ Manufacturing has introduced two new options to its Criti-Clean Ultra HEPA filtration units to more effectively combat airborne viruses, such as SARS-CoV-2, as well as bacteria, mold and other pathogens. The new built-in modules include Ultraviolet-C (UV-C) Radiation and Needlepoint Bipolar Ionization.
The Criti-Clean Ultra is a fan-powered laminar flow HEPA filter diffuser that provides a steady stream of purified air into a room. It is available as a traditional ceiling-mounted unit, as well as a completely portable model that comes on wheels and plugs into a standard wall outlet.
The new UV-C Radiation module assists in sterilizing particulates in the air stream and also disinfects the HEPA filter. When microorganisms are exposed to UV-C, the light’s radiation penetrates their cell walls and disrupts the structure of their DNA to neutralize them.
The Needlepoint Bipolar Ionization module produces a stream of negative and positive ions, which attach themselves to microorganisms and render them inactive by depriving them of hydrogen. The resulting larger clusters of particles are also more easily trapped in the HEPA filter.
All Criti-Clean Ultra units include a standard HEPA filter that traps 99.99 percent of particles as small as 0.3 micron. They can also be upgraded to ULPA filters (99.9995 percent at 0.12 micron).
In addition to standard air-supply models that push clean air into a room, the ceiling-mounted and portable Criti-Clean Ultra are available as reverse-flow units for creating patient isolation areas. These units draw potentially contaminated air in, then exhaust clean air out of the room through ductwork.
