CFM

How Much CFM do you need?

If you search all the web sites that want to sell you a system, you will find that most of them recommend that you buy a system with rated CFM performance that is about 2 – 3 times the  square feet of rooms in your home. I have talked to customers who say they should have installed more when they bought their first system. I know some who added systems later and were very pleased.
