Here's the chart: https://youtu.be/RkjRKIRva58?t=6
0.52 was one of the best static pressures of the group.
He goes on to say "Even though the 3M 1900 which is a MERV 13 filter does have a very tightly woven filter media, it overcomes the static pressure challenge by having 54 pleats and 1560 square inches which is more than twice as much as any of the other one inch filters."

14 x 24 in Kirkland 2200 does the job for me. Not a perfect fit but the filter size is significant larger than the intake size so it works for me.

That's what I use instead. The Winix C545 is on sale at Costco on a regular basis for $100. Comes with 2-years worth of filter. You can even put it close to the intake of the A/C.

Hopefully its really HEPA
The Winix filters used to go on sale for $30 at Costco but have not seen that in awhile.
