Not enough resistance I don't think. That seems to be a clean room filter and ionno if you could pump enough air through to achieve laminar flow

Neither. The way I understand it they pumped 549cfm through it and it only developed .63wg which basically means you'd have to buy a 1000cfm blower lol.

Look for a filter with at least a .75 resistance up to 1.5wg
