Frequently Asked Questions
What are the most common causes of IAQ problems?
The most common causes of IAQ problems in buildings are:
- Not enough ventilation, lack of fresh outdoor air, or air that has been contaminated with allergens, such as pollen or dust, being brought into the building
- Poor upkeep of ventilation, heating, and air-conditioning systems
- Dampness and moisture damage due to leaks, flooding or high humidity
- Occupant activities, such as construction or remodeling
- Indoor and outdoor contaminated air
- Lack of proper upkeep with regard to cleaning activities such as cleaning of carpets, removal of trash, and other regular “housekeeping” activities.
Is there a single test that can find an IAQ problem?
No, there is no single test that will identify all IAQ issues. EHS typically uses a variety of instruments to produce a comprehensive summary of air quality parameters.
How long does sampling take?
Depending on the type of monitoring that is required, sampling can range from a few hours to a week or more. EHS can provide additional information on sampling times during the initial meeting.
Are there currently any regulations on mold?
No, there are currently no established levels for mold exposure. The effects from mold exposure can vary between individuals based on many factors.
What is considered good IAQ?
The qualities of good IAQ should include comfortable temperature and humidity, adequate supply of fresh outdoor air, and control of pollutants from inside and outside of the building.
