Gentlemen,

I would like to Apologize for my long abscence. I have been, and still am, battling several health issues, and some family issues as well.
This does not include my last PC going Nuclear on me and having a total "Meltdown"! Well Thank's to the Fine People at the VA, I am now "On-Line" again.
Basicly I would like to Thank all the Membership who helped me out when I needed it, and for putting up with a "Newbie".

Now again, I could use your help.....I want to turn a Blower I have into a "Positive Over-Pressure System", using HEPA Filter's, in the event that the wife and I are ever forced to "Shelter In Place".
Basicly I want to use the Blower to Overpressure the room....this forces air out any crack or crevice, not letting any "Bad" air in. What I need to do, is figure out the configuration on how to set it up with HEPA filter's, that can be changed "Safely", from INSIDE, the room!
I have seen plans on the Web, but up to this point, have had no luck in finding them. Can anyone help???
