Carpet offgassing?

[PamNY]

No, I don't have food allergies.

The more I think about it, the more I think mold makes sense.

Crankin, what do you do about mold allergies? Do you tolerate it, or is it necessary to avoid completely?

My partner does have mold allergies...he gets pounding headaches. For instance he can not be in a greenhouse or plant conservatory.

We cannot have hardly any potted plants indoors because of his mold allergies. It's naturally occurring in the soil.

1 container plant for herb or pointisetta is ok. That's it.

Who knows, could mold be in the walls...then get into the HVAC system.. Or mold underneath the carpet overlay, etc.

One question for allergy-knowledgeable people: I don't have any allergies to mold (or anything else) outdoors -- does that make it unlikely I'd be reacting to mold indoors?

Shootingstar, you comment is interesting. I recently started feeling lightheaded in a greenhouse. I thought it was because I'd been walking slowly though the botanical garden -- slow walking (like in a museum) makes me exhausted. But now I wonder if it was mold.

Well, for awhile, I took allergy shots at 2-3 various points in my life.
Now, I live in a house that has hardwood floors, and I am scrupulous about keeping things clean. I don't do well in humidity, so in the summer, I run the AC when sometimes it's more humid than hot.

I don't know a lot about the specifics of molds, but my allergist tests for seven different genera of molds, and I'm being treated for three. I'm sure certain kinds of molds thrive better indoors while others are more common outdoors.

Hope PamNY you'll pin down the mold mystery. It's always good to understand any allergies that one acquires over time.

For the moment, I'm going to do nothing -- except try to manage the problem with ventilation at my friend's house. If problems occur in other places, then I will look into it.

I have let her know what's going on; she is resistant to the idea that there might be mold, but I think a building with persistent (and unresolved) leaks when it rains is an ideal place for mold to grow.

Thanks to everyone for the replies.
