Indoor Air Quality Monitoring and Treatment       

Common indoor pollutants that might be present in your home:

  • Biological pollutants, like mold, dander, pollen, dust mites, and bacteria
  • Chemical pollutants, which include volatile organic compounds (VOCs) like formaldehyde, and the other chemical pollutants lead and radon
  • Combustion pollutants, like carbon monoxide and tobacco smoke (incidentally, VOCs and other chemical pollutants may result from combustion)
DDAair provides tests specific for one or up to 14 common biological pollutants, from house dust mite allergens to animal allergens to pollens. The technology being used is called Multiplex Array for Indoor Allergens (MARIA), which has been proven by research studies.
Volatile Organic Compounds (VOCs)

Volatile organic compounds (VOCs) are organic compounds that easily become vapors or gases, hence their “volatile” nature. Next, the “organic” part stems from the chemical definition of organic compounds, which requires that they contain the element carbon. Some organic chemicals naturally occur in living things, but many are synthetic and found nowhere in nature.


We have different chemical products in our homes, which can release organic compounds while they are being used, but surprisingly, even when they are stored! The usual suspects that contain VOCs are paints, cleaners and disinfectants, stored fuels, wood preservatives, and dry-cleaned clothing. Other products that can contain VOCs are building materials, furnishings, office equipment, and graphics and craft materials.


The potential for an organic chemical to cause health effects will depend on the toxicity of the VOC–some are very toxic, and others create no known health problems. Long-term exposure to VOCs can cause kidney, liver, and central nervous system damage. Short-term exposure to volatile organic compounds can result in eye and respiratory tract irritation, headaches, dizziness, fatigue, loss of coordination, allergic skin reactions, memory impairment, and nausea.

Formaldehyde

Formaldehyde is a well-known VOC, and like all its volatile organic siblings, we are exposed when the chemical is released into the air, and we breathe it in. The most common place to find formaldehyde is in the manufacturing of urea-formaldehyde resins, which are used in particleboard products. It is also found in building materials and insulation, household products like glues, permanent press fabrics, paints, and paper products. The chemical is even used as a preservative in some medicines, cosmetics, and other personal care products.


The health effects of formaldehyde range from eye, nose, and throat irritation to neurological effects and increased risk of asthma and allergy symptoms. The World Health Organisation has determined that formaldehyde is a known human carcinogen.


DDAair offers professional indoor air quality testing for formaldehyde and effective removal service.


Method

DDAair uses a combination of technologies to effectively remove VOCs and formaldehyde. Photocatalyst coating is applied to areas of sufficient sunlight and artificial light. Chitosan coating is applied to areas of little lighting and the interiors of cabinet and wardrobe. Composite biological enzyme air spray is then applied generally to give extra protection.
