AtmosAir Bi-Polar Ionization
- Disinfects air by producing and distributing a controlled amount of positive and negative air ions, which interact with oppositely charged elements.
- Does not rely on contaminants passing through the unit to be cleaned, the bi-polar process allows for air cleaning to occur within the desired space treating a larger volume of air within the breathing range.
- AtmosAir’s patented BPI technology does not produce harmful chemicals or products such as ultraviolet (UV) and ozone.
- Effective against bacteria, spores, voc compounds and particles.
- Can treat the source of contamination.
- Can be incorporated into central HVAC systems or used as stand alone units.
- Will not restrict airflow when incorporated into central systems.
- Requires maintenance each year to replace worn tubes.
HEPA (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 as stand alone units.
- Is effective on particulate removal.
- Cannot treat source of contaminants, can only filter contaminated air from entering an area.
- Is not effective on many mold spores, bacteria and viruses.
- Is not effective on VOC’s, gasses and most odors.
- Will restrict airflow 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 as stand alone units.
- 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 affected.
- UV is dependant on contaminants being exposed to the light field for a time period long enough for the contaminant to be treated.
- UV is dangerous when exposed to humans.
- Some elements (for example Aspergillus Niger) are resistant to UV altogether.
- In not effective on VOC’s, gasses and odors.
- Is not effective in reducing particulate levels.
- Some of these systems produce undesirable ozone levels.
- Will not restrict airflow when incorporated into central systems.
- Requires maintenance each year to replace worn bulbs.
Electronic Air Cleaners
- Charges particles by generating single polarity ions to pass through the unit to attract to an oppositely charged collector cell.
- Uses high energy (up to 25,000 volts) to produce ions.
- Mostly ineffective against bacteria, spores, odors and voc compounds.
- Requires maintenance (sometimes monthly) to clean collector cells or unit’s effectiveness will diminish.
- Can only treat air which passes through the collector cell.
- High energy used to generate ions will create ozone.
- Can be incorporated into central HVAC systems.
“Dust Collectors”
- Examples of these units are the many “stick style” consumer units.
- Charges particles by generating single polarity ions to pass through the unit to attract to an oppositely charged collector cell.
- Units do not produce adequate airflow to effect large spaces.
- Only effective inches from the unit.
- High energy used to generate ions will create ozone.
- Single polarity charge may produce particles clinging to surfaces.
- Ineffective against bacteria, spores and voc compounds.
- Cannot be incorporated into central HVAC systems
