I'm blown away by the effectiveness of a can of spray foam and a roll of duct tape! "The concave filter" should be the title of this piece. Congratulations on publishing, Parker - step one on spreading the word and sharing the knowledge.

Air Sealing really can be the most cost effective initial comfort, efficiency, and indoor air quality improvement!

You can perform simple DIY air sealing of obvious leaks that you see, or feel on a windy day. I perform a Blower Door test to quantify leakage rates, as well as finding the hard to see air leakage points. I also get a post sealing leakage number that I can use for my energy modeling and HVAC sizing calculations.
