Competing technologies

Read about common air purification methods and how they compare with Aircode™ technology.


HEPA Filtration

(High Efficiency Particulate Air) Filtration

  • Pleated type filter that has proven 99.97% efficient to trap particles 0.3 microns and larger
  • Can be incorporated into central HVAC systems or used stand alone
  • Can not treat the source of contaminants, can only filter contaminated air from entering an area
  • Is not effective on many mold spores, bacteria and viruses
  • Will restrict air flow when incorporated into central systems and increase energy costs
  • Requires several maintenance visits to replace used filters each year

UV (Ultra-Violet light) Purification

  • Disinfects by passing air through ultra-violet light
  • Can be incorporated into central HVAC systems or used stand alone
  • UV light can only treat contaminants that pass directly through the light field; ambient air that does not enter through the light field will not be treated
  • UV is dependant on contaminants being exposed to the light field for a time period long enough for the contaminant to be treated; the treatment periods vary greatly depending on which contaminants are being targeted
  • UV is dangerous when exposed to humans
  • Some elements (for example, Aspergillus Niger) are resistant to UV altogether
  • Will not restrict air flow when incorporated into central systems
  • Requires maintenance each year to replace worn bulbs

"Needlepoint" Ionization

  • Creates single polarity ionization to attract particles
  • The single polarity will use walls or any nearby surface as the needed opposite polarity. This will attract the charged particles to that surface, producing "black or dirty walls"
  • Will only work in a small proximity zone immediately around the unit
  • Uses high energy (25,000 to 40,000 volts) to produce ions
  • Mostly ineffective against bacteria, spores and VOC compounds
  • Creates uncontrollable positive ion output which when coupled with high energy output will create ozone
  • Will interfere with wireless and RF equipment
  • Can not be incorporated into central HVAC systems

"Dust Collectors"

  • Examples of these units are the many "stick style" or "tower style" portable units sold on TV or in consumer electronics stores
  • Collects particles on a metal surface contained in the unit
  • Produces single polarity ions by electrifying collector plates
  • Only effective inches from the unit
  • Creates ozone
  • Ineffective against bacteria, spores and VOC compounds
  • Cannot be incorporated into central HVAC systems

The Aircode™ System

  • Disinfects air by producing and distributing a controlled amount of positive and negative ions which restore oxygen molecules to an active state
  • By controlling positive ion output and using low energy (2,200 to 3,000 volts) ozone is not produced
  • Effective against bacteria, mold spores, VOC compounds particles and nano-particles
  • Can treat the source of contamination
  • Can be incorporated into central HVAC systems or used stand-alone
  • Will not restrict air flow when incorporated into central HVAC systems
  • Requires annual maintenance to replace worn tubes
