We use the Healthy Home Standard to validate an unhealthy mold issue within a home.
Our independent third party laboratory uses the Healthy Home Standard for a more cohesive interpretation of what is going on in your home.
Using the Healthy Home Standard to interpret your sampling results is simple. The Indoor Air Sample is compared to the Outdoor Air Sample, (We call this our control sample).
If there is significantly more spores of a mold genus found indoors then on the outdoor sample, this would indicate a possibility of unhealthy mold colonies growing in your home.
Using the mold testing results along with the visual inspection results we are able to get a better picture of what is truly happening within your home.
Each mold genus has a threshold that must be met before it would consider it elevated.
Aspergillus/Penicillium must have >800 spores/m3 found indoors verses outdoors.
Example - if the outdoor sample showed 120 spores/m3 then the indoor sample would have to be 920 spores/m3 to be considered elevated.
However, Stachybotrys needs only 10 spores/m3 to be considered elevated. So if the outdoor sample showed only 13 spores/m3, the indoor sample would be considered elevated at 23 spores/m3.
