How to calculate static pressure for FILTER

Hola Amigos,
I'm stumped on this static pressure thing when it comes to my filter.
On the filter I was given a few specs, but I'm not too sure what the static pressure is given these specs.
The following is what was on the label of the filter:
Resistance ("WG) - .32
Test Flow - 162 CFM
Penetration .00400
Size 24 x 11 x 5.875
Yes I know this filter is kinda dinky, but I don't have much room and am honestly looking for one to do agar work which this suites my needs. Not looking to find one to compensate if ya know what I'm saying.
Gracias,
Pinche cabronas!

The listed resistance (“WG) is the static pressure of that filter @ the rated airflow. So your filter will have a static pressure of 0.32” WG @ 162cfm. For proper laminar flow you need to have ~100fpm of airflow across the face of the filter. Your filter has an area of 2sq ft, so you would like to flow about 200cfm. You can use fan law 2 to calculate the static pressure of your filter @ 200cfm.
(cfm2/cfm1)^2 * SP1 = SP2
(200/162)^2 * 0.32 = SP2
(1.235)^2 * 0.32 = SP2
1.525 * 0.32 = SP2
0.488 = SP2
So at your desired 200cfm, your filter will have a static pressure about 0.488” WG.

Shiiiiiiiiiiieettttt son....
I must propose a toast, You sir have my most undying and unrelenting gratitude for surmounting such an ambiguous endeavor that thee presumed as a withering ill-fated phantasm of the mind in search of this mysterious decipher to such an arduous mind fuck of a task. So I must say this
"There are good ships, and there are wood ships, The ships that sail the sea. But the best ships, are friendships, And may they always be."
