So where do you buy these merv 12 filters? Can i use these in my furnaces fresh air intakes as well? If im recovering 95% of my heat when exhausting, i can expect the incoming air to be within 5% of the outgoing air temp? i see this is a "self balancing" erv? so there should i send this back to the manufacturer if the pressures are not the same? Also what positive pressure should i expect to maintain with the pressure guard system installed, and how long after the door is closed on entry?
