IAQ Indoor Air Quality Alternate Method Saves Up-Front Cost, Plasma Air Ionization

The primary method for reducing indoor air pollution is to dilute the polluted indoor air with outside air.  Building codes assume that the outside air is cleaner than the inside air.  Outside air is not always cleaner than the inside air.

Many of the indoor pollutants emmited into the air originate from people.  Generaly ac/heat systems are designed to introduce 20 cubic feet of outside air into the building per minute per person.  This is raw air and must be cooled, heated, dehumidified or humidified.  Substantial energy is used to treat this outside air.

99.8% of all airborn particles pass through a typical filter.  Agglomerating smaller particles into larger ones using  plasma air ionization improves filter efficiencies.  The smaller particles stick together and fall to the floor or are removed by the filter.

An alternate method seldom used is to remove pollutants from inside air vs the common method of diluting the inside air.  ASHRAE (Association of Heating Refrigeration Air Conditioning Engineers) and IMC (International Mechanical Code)both allow for the reduction in outside air introduced into by using the IAQ procedure.

Another benefit of using the IAQ method is the reduction of the size equipment required to maintain the space temperature.  This reduces the up- front cost of installing a new system and the operating cost of the system.
