Re: what are the first health signs that you're in a bad building?

[Guest guest]

The first sign of poor indoor air quality is high relative humidity

in the space. After 3-4 days of +80% RH, mold is growing. In 3-4

weeks a musty odor may be noticeable. Sensitive people start

complaining. High spore counts peak after the area begins to dryout

which could be a month after people become sick. Therefore always

monitor relative humidity is a space you are concerned about. When

the relative humidity goes above 65% for an extended number of days,

investigate the cause. This is my experience with several

investigation of reoccuring mold problems.
