POLARIZED FILTER

IAQ
Polarized media filters combine elements of electrostatic air cleaners
and passive mechanical filters. By polarizing the individual filter fibers,
charged particles are efficiently attracted, captured and held in place,
removing harmful elements from the airstream.

studies show indoor air quality is 2-5 times
worse than outside air quality. And hospital
patients may spend days and weeks isolated
indoors, surrounded by a high concentration of
contaminants.
The U.S. Department of Health and Human
Services has identified the reduction of healthcareassociated infections as an Agency Priority Goal
and acknowledged a growing consensus that HAIs
should be eliminated. The International Facility Management Association continuously encourages members to challenge standards and practices if facilities
do not meet indoor air quality goals. In its "Operating
Sustainable Facilities" manual, IMFA advises that
facility managers "must look at their interiors from
two perspectives: that of a facility manager interested in energy efficiency and lifecycle impact on the
environment and that of a facility occupant who seeks
and deserves healthful and comfortable surroundings," and that "to improve IAQ, a facility professional
should understand potential and actual threats to IAQ
in the facility and take steps to improve ventilation
and air quality as needed."

Passing through an ionization field causes
harmful compounds to break into one or
more of four basic elements: oxygen,
nitrogen, carbon dioxide or water vapor.
PLASMA FIELD
Upon entering the ionization field, positive and negative ions surround
harmful ammonia particles, breaking them down into hydrogen and
nitrogen naturally occurring in the atmosphere.
