Commercial Buildings
Poor indoor air quality in public places is known to affect the attitude, concentration, productivity and health of people.
AAFs particulate and molecular air filters are designed for use in the outside air intake, the supply air stream and the return air stream. Inside the building, AAFs filters are used to remove particulate and odours created inside buildings from human activity as well as from offgassing of furniture and wall coverings etc. In the supply air system AAF filters remove dust and molecular contaminants from the outside air intake and the return air stream while AAF air filters in the outside/makeup airstream purge molecular and particulate pollutants generated by exhaust gas fumes from vehicles and industrial processes.
| Contaminant | Source | Type of Problem |
| Hydrogen sulphide, acetone, ketones, alcohols, aldehydes | Offgassing of building materials. Residual odours from cleaning detergents and agents |
Poor IAQ, odour and skin, eye and nose irritation complaints |
| Sulphur, dioxide, nitrogen, oxides, formaldehyde, hydrocarbons, ozone | Vehicle exhaust gases entering air intake. Offgassing from furniture |
Poor IAQ, skin, throat and eye irritation complaints |
| Aldehydes, ketones, bio-organic chemicals, alcohols, residual tobacco smoke | Offgassing of humans. Inadequate ventilation and filtration |
Poor IAQ and odour complaints |
| Hydrogen sulphide, aldehudes, VOCs, mercaptans | Inadequate ventilation or filtration of cooking odours | Nuisance odours and poor IAQ |
