do you even physics?

Air is pulled through the filter by a difference in pressure. Pressure and force are (more or less, a function) of the same thing. It doesn't take a rocket scientist to realize that the force or pressure on the filter decreases as you increase the angle of fan force.

Looking at the macro set up. Of course, you can get more specific as you look deeper into the design of the filter itself. You can bring in the design of the filter, the MFP (mean free path) of the air molecules flow, the porosity of the filter material, etc.

Bottom line is filters work because of a net force applied to it, pulling air particles through it (F=ma). This is freshman year physics free-body diagram stuff.

Are yall really that dumb? Do you really think the millions of industrial designs are doing it incorrectly and they should have triangular designs?
