Aerisa ionization technology for commercial applications is based on ions produced by an ion generator, configured either with needlepoint brush electrodes or tubes. These ion generators are mounted either inside a building’s air handler or in the supply ductwork. Highly ionized air with millions of ions (O2+ and O2–) are delivered in each cubic foot of air through the ductwork and into the treated space. Because of their charge, these ions proactively attack the contaminants at their source to vastly improve indoor air quality.
Airborne Particulate Removal
A University of Minnesota study shows that 98.5% of airborne particles are smaller than 0.5 microns. This means that these particles will not “fall out of the air” nor will they be caught in particulate filters. Because the ions have a charge, these airborne particulates agglomerate and increase in size. Larger particles are trapped more efficiently by even poor quality return air filters. Larger particles also settle much faster and may then be removed by housekeeping. Either way, previously airborne particles are removed from the breathing zone. Particulate may contain bacteria, virus, mold and other allergens—thus, their removal creates a much healthier environment.
Aerisa ionization technology “casts a broad net” over a host of odorous compounds found in commercial applications, to include ammonia, hydrogen sulfide and acetaldehyde. Highly ionized air oxidizes these odor causing compounds into less objectionable molecules such as water, nitrogen gas and elemental sulfur.
Following is an example of how Ammonia (NH3) is oxidized and broken down into its individual components. The process of ionizing a molecule is instantaneous and irreversible. Click on graphic for detailed information regarding the ionization of NH3.
New carpeting, paint, furniture, office equipment, glue and solvents are only a few commercial materials that emit VOCs. Like that for odors, highly ionized air oxidizes VOCs, breaking these chemicals into simple, harmless compounds. This is particularly important in new construction where all materials are new and emit VOCs at very high levels.
Bacteria, Mold and Virus
As mentioned above, ionization will help smaller particulate matter agglomerate and fall out of the air or be caught in particulate filters. These particles will absorb airborne bacteria, mold and virus thereby removing them from the breathing zone. However, ions will also oxidize the cell walls of bacteria, mold and virus. When the cell walls of these microorganisms are oxidized, they become sterile and are no longer able to multiply. When this happens, they simply die off and are permanently removed from the space.
