Mold and Indoor Air Quality (IAQ) continue to get a lot of attention. As a result, many people are increasingly concerned about the quality and safety of the air they breathe at home and at work. In some cases, the concern is justified. In many others, however, the concern is not justified. Concern often results from media hype, scams and/or unqualified professionals anxious to "help" rather than objective, factual information.

How can you know the difference?

Here are a few thoughts.

1. Be well informed. Be sure to use objective, reliable sources. Here are a few Web sites we trust:
1. www.epa.gov/iaq
2. www.iaqcouncil.org
3. www.iaqtechnologies.com
4. www.aerotechlabs.com
2. Keep things in perspective. There are more than 100,000 types of mold and fungi in our world. Most of them actually contribute to our healthy environment. The mere existence of mold does not necessarily signal a hazardous condition.
3. Use background levels as a reference. Any credible air-quality testing should be done by measuring outdoor levels as well as indoor levels and comparing the results.
4. Look for a "credible voice of reason." Many "experts" do not have the experience and qualifications suggested by their titles or certifications. Check references and qualifications before accepting their advice and recommendations.
5. Safety is relative. No standards have been set for safe levels of biological contaminants (mold, fungi, etc.) in air. Further, it is unlikely that any such standards will be set because "safe air" is dependent on many variables including temperature, humidity, availability of nutrients, synergy among contaminants, respiratory sensitivity, duration of exposure, etc.

Mold and IAQ are legitimate concerns. However, balance and perspective are also important. Try to be as informed as possible. Avoid making assumptions or jumping to conclusions. Be suspicious of any information until you have satisfied yourself that it is credible.
