Homes are essentially boxes of air, complex boxes of air. What they are made of, what we bring into them, how we condition them, and how we use them all contribute to the contents of the air inside them. The point of IAQ is to improve the quality of the air in the home. a few ways of improving the indoor air quality in the home are:
- Controlling the temperature and humidity. Keep humidity between 30% and 50%. (This will keep down dust mite and other micro-organism growth)
- Ventilation- consider whole home ventilation or spot ventilation ( ventilate near the source of the pollution: bathrooms, kitchens, garages, hobby areas, etc.)
- Identify and Remove the source of pollution – don’t bring items that put off VOC or air pollution into the home.
- Filtration – change your heating and air conditioning system’s filter regularly and use a filter with a minimum MERV 11 rating. Install a media filter or air cleaner on the heating and cooling system.
It is clear that indoor pollutants have an impact on people’s health. Installing air filtration systems, adding ventalation and dehumidification equipment and removing the source of the pollution are the most effective options. While diluting the concentration of the pollution is the next best step in reducing the potential impact. Dilution can be accomplished by installing various air purification system. the most common air purification equipment is the UV light or UV air purification system. while these UV systems require more frequent maintenance and have a limited effective reach, they provide a way to tackle the challenges of IAQ at a more cost effective approach .
