Don -
Hope you are doing well and enjoying life!
I am working on an IAQ program for existing homes with the EPA and wondered if I could get you to take a look at a short section on combustion safety. I think it's covered, but I would welcome your input.
Thanks. Paul
Don,
I never got a link from you to the low cost particle monitoring group. Or if I did I don't know where it arrived. Thanks in Advance, Rana
Thanks, Don!
