Home Inspections - Air Quality Check

This is generally an indoor air quality spot check at one point in time but can still be quite revealing. Tests done by the U.S. Environmental Protection Agency, EPA, that compare risks of environmental threats to public health repeatedly rank indoor air pollution (organic compounds, including secondhand smoke, radon, biological pollutants and other compounds) among the top five risks. Newest is the worry from airborne particles. Sofisticated electronic equipmement (that we now have) can count polluting particles down to 0.3 microns or less. These particles do not settle like normal dust, you breath them in constantly.

Guidelines used refer to standards promulgated by the American Society of Heating, Refrigerating and Air-conditioning Engineers Inc. (ASHRAE). These can be located in the ASHRAE documents Ventilation for Acceptable Indoor Air Quality (ASHRAE 62-2001) and Thermal Environmental Conditions for Human Occupancy (ASHRAE 55-2004).

We test some of the basics as temperature and humidity as well as carbon monoxide, CO, and carbon dioxide, CO2. At the next level we test ozone, volatile organic compounds, nitrous oxides and ammonia. What few people test because of the high cost of the analytical equipment is particulates.

Particulates can be classified as either respirable (less than 5 microns in diameter) or nonrespirable. Respirable particles can penetrate into the lower lung and can cause damage. Nonrespirable particles are trapped in the upper respiratory system and can cause irritation. IDPH recommends that particulates 2.5 to 10 micrometers in diameter (PM 10) be maintained at less than the USEPA National Ambient Air Quality Standard (NAAQS) of 150 micrograms of particulates per cubic meter of air (ug/m 3) and particulates 2.5 micrometers in diameter or less (PM 2.5 ) be maintained at less than the NAAQS of 65 ug/m 3 during a 24-hour time period.

We can test particle counts from 0.3 microns to 10 microns. This covers the whole range of concern. Although there is no universal stands for particle counts I can still give you an opinion about our findings. Better still, we can frequently make recommendations to improve things in this area of indoor air pollution. We do comparison studies.

Lastly, we can test other things as radioactivity. These are spot checks and not used by others in part because of a lack of standards for low levels. But again I can tell you what other homes have and if yours is that much different. I will not do statistics, just a simple comparison and my personal opinion.

Before you move into a new home or building or office. Get a spot check for indoor air quality. Humidity and temperature and mold are not the only things to worry about.
