Thanks for the detailed information!
Maybe you can help with the whole idea of dangerous materials.
In my case I have some formaldehyde sensitivity from a job doing formica work. I know that some plastics decompose into formaldehyde, but I don’t really know how to think about the amount generated versus their real danger (or irritation).
There are lots of these byproducts, and I have been thinking (for instance) about what I am inserting into my neighbors air stream when venting out the window.
Any thoughts?
