To help people determine if the air in their house is healthy we have created an Indoor Air Quality Survey. During the survey we will test for the problematic substances found in indoor air. We will look for presence of Formaldehyde and VOCs. The are common from manufactured items that are out-gassing. We will test for particulate matter. Particulate matter are tiny particles in the air that come from dust or dirty vents. We will do a lab analyzed mold test and a short radon test. This test is only run for a one hour period and may not accurately predict the level of radon in the house. Radon levels vary by the hour of the day, the weather and the season of the year. Finally we will check for excess levels of carbon dioxide and unburnt fuels such as methane or propane.
