30x30, .0065" Wire, 64.8% Open
42x42, .0055" Wire, 59.1% Open
43x43, .0045" Wire, 61% Open
58x58, .0045" Wire, 54.6% Open
60x60, .0045" Wire, 53.3% Open
70x70, .0037" Wire, 54.9% Open
84x84, .0035" Wire, 49.8% Open
The 80x80 mesh that I have with the .0012" wire diameter is only 3" square - too small for me to test, but when I blow thru it, it's like it's not even there (over 80% open).
