I am not going to attempt to discuss the entire topic of mold in this post.
Even though mold may not be visibly present in the building–its spores are literally everywhere. For molds to grow in the indoor environment (at least the ones we are most often concerned about), most will need oxygen, food, suitable temperatures and water.
In the indoor environment the one of these that we can effectively control the most to prevent its growth is water. If we can’t control moisture we are going to have a real problem controlling mold.
Mold can grow on most surfaces. Even dust is a suitable food for mold growth. In the cleanest of households there is going to be dust in the air that will circulate and find the wettest (coolest) surfaces. As this dust collects on even glass or metal surfaces it becomes a medium suitable for a mold feast.
The temperatures that humans are comfortable at are ideal for mold as well, so there is not much we can do regarding temperature to control mold.
Unfortunately humans don’t do well without oxygen–so it is a good idea to keep air in the building as well.
But air is something we have to consider–because it is air-quality that is at the heart of the issue.
It has been demonstrated that there is a connection between damp household air and a “slight” increase in health related issues. There is scant info to support that it is mold in this damp air that is the sole culprit in these health issues. Other things that are also often associated with damp air, such as dust mites, bacteria, termites, protozoans, endotoxins, VOCs, formaldehyde, pesticides, viruses, and overall poor ventilation, must be considered in the whole picture of how the air in a home is affecting occupants adversely. In fact, in most instances household dust (translate dust mites) makes up the biggest percentage of this mucky air.
In light of this, it makes more sense to fix conditions that contribute to excess moisture in the building and to focus on ensuring that we maintain good air quality in the building–than it does to focus on mold.
Thanks to faulty media-induced-hysteria, mold has become “Gold” for some–a multi-billion dollar industry based on next to nothing, other than being able to count on people’s vulnerability, fear, and lack of good information–victims of misinformation and disinformation.

I can remember doing inspections before the “Gold Rush” started.
I am old enough to remember the old Elvis song, “Fools rush in…..” 🙂
Great article Charles. It’s about time somebody told the truth instead of perpetuating the media’s mold myth just to make a buck.
Humidity of the building sometimes causes it for the growth of the molds.
