Don't know, but I'm curious as to what you learn. Have you ever tried to measure DP relative to other standard throwaway filters?
When my new system was installed I soon dialed back to the lowest restriction pleated (and electrostatically charged) filter I could find on local shelves. The installer put in a simple flat screen "filter" that had next nothing in the way of filtration ability...and little DP. I then put in a generic pleated filter of modest claims...and immediately noted a very high filter DP--high enough that I created a simple tubing manometer to measure it, then measured the blower power draw and said, "Hell, no!" Larger boots (matching the original furnace filter size rather than the new one) in standard filter sizes are no longer sold, so I decided to reduce the media DP. I picked up a low rated "Filtrete 600" pleated filter. It provided lower DP, but still seems to filter properly.
I've used low restriction filters (K&N's with low restriction velocity stacks) in cars I modified for greater horsepower and torque, never had any problems with them. Washed them and reoiled about twice a year. Engines never suffered over 100K of nearly daily redline revs, and I measured substantial performance gains from the filters alone.
