Question from PJ

Dear Debra,

Your article on Building for MCS mentioned “passive ventilation” in homes, in addition to open windows. Our home is designed without a duct system. Are there options for ventilation, that don’t depend on a duct system? Thank you for your help.

Debra’s Answer

That mention of passive ventilation was in a quote from Mary Cordaro (h3environmental.com), who is much more knowledgeable about ventilation options than I am. She is a consultant to people with MCS and is well trained in building science and ventilation systems.
