 Episode Title: 

Keeping the moisture out of your home

 Episode Summary: 

Contractor John talks about the importance of exhaust fans in your home to help keep moisture out, especially the bathroom fan. How to size it, what is CFM, what is a “sone” rating are a few of the items covered.

 Topics discussed in this episode:

The acronyms mentioned in the show

ACH = Air Changes per Hour

CFM = Cubic Feet per Minute

CFH = Cubic Feet per Hour

Formula for properly sixing your bath fan

W x L x H x 8 ACH =CFH (cubic feet per hour) then divide by 60 (minutes) to get CFM

***** Now if you run the formula you will get 48 cfm for a typical 9 x 5 bathroom. The smallest bathroom exhaust fan I have seen is 50 cfm, which will work just fine.
