Proper determination of IAQ involves the collection of air samples. Indoor air quality (IAQ) is a term which refers to the air quality indoors of the home or buildings, The health and comfort of occupants affected by gasses (including carbon monoxide, radon, volatile organic compounds), particulates, microbial contaminants (mold, bacteria) that can induce adverse health conditions.
How can I improve the IAQ of my home?
Increasing the amount of fresh air brought indoors helps reduce pollutants inside. When weather permits, open windows and doors. Bathroom and kitchen fans that exhaust to the outdoors also increase ventilation and help remove pollutants.
Always ventilate and follow manufacturers’ instructions when you use products or appliances that may release pollutants into the indoor air.
Central heaters and air conditioners have filters to trap dust and other pollutants in the air. Make sure to change or clean the filters regularly.
The humidity inside can affect the concentrations of some indoor air pollutants. High humidity keeps the air moist and increases the likelihood of mold. Keep indoor humidity between 30 and 50 percent. Use a moisture or humidity gauge, available at most hardware stores, to see if the humidity in your home is at a good level. To increase humidity, use a vaporizer or humidifier.
To decrease humidity, open the windows if it is not humid outdoors. If it is warm, turn on the air conditioner. For Humidity control, it is recommended to install a central Dehumidifier system.
