This seller boarders on the ridiculous. how am i suppose to match an inline fan without knowing the cfm rating of this filter? lol

I have it on a 2 hundred and something fan and it does great

At what cfm would this filter provide laminar flow? without this info the hepa rating is worthless.

These aren’t designed for that particular application and I am curious as well. I’ve wanted to use one to supply a clean space. I suppose with a speed controller it can be achieved. I don’t know how much it effects it but I would imagine a planar or flat type HEPA filter would be ideal as you’re never going to get air to emerge at a perfectly perpendicular direction from the membrane as the flow is restricted into a vent by design. You could get around it by modifying the area of the channel but by controlling the speed you have the best chance. It’s very heavy duty and performs beautifully for keeping a space clean.

I'm not seeing a CFM rating (a rather important spec of a filter) ?

I run a 4” 190 cfm exhaust fan on a sealed unit where this is the only inlet for air. There is definitely a good suction in the tent which would tell me that the filter is rated much less than the 190cfm, however it works well paired with this size fan.
