For anyone interested in making there own flow vents, this chart explains the MERV values and gives you a pretty good idea how much and what is going to be blocked by which fliter...I just order two 20x20x1 inch MERV 14 with a MPR of 2800 from Amazon and I'm pretty sure they'll reduce the chances of contamination significantly...
