Question from Paula

Hi Lisa,

My situation is that I’m getting central air conditioning installed, and want to avoid all toxic components. I’m wondering if having PVC or Microban in my attic is something I should worry about (my attic isn’t air sealed from my living space, and air sealing is probably too expensive at this time). I guess my question is, is there a distance from which toxic chemicals aren’t a health danger?

Lisa’s Answer

The distance is not really the important factor since air will be moving through the AC system, through your vents, and into your home.  I would avoid PVC and Microban if possible.
