I used to use the 3m filters, purple if i remember correct. I fell for the filter as much dust as possible thought.
Yes, using the purple filters to move heavy air conditioned air is not an ideal situation. I use the red filter throughout the year. I'm sure the stronger fan has a lot to do with the increase in air flow.
The reason the filter was pointed out is with the stronger motor the airflow on my longest run was still horrible.
The stronger motor has more HP but same RPM as you do not want higher rpm but thats a whole other topic. Stronger lets it deal with resistance better but essentially its still moving air at the same speed in most cases.
To be specific he cleaned my a-coil which seemed to help a little, changed motor helped a little, pointed out I should really try a less restricting filter so I listened and am glad.
Just sharing a real life experience.
The fiance has bad allergies at times of the year and this ear we actually picked up a very restrictive filter again to see if it would help and honestly ended up removing it a few hours later due to the air flow dropping so much, I was like wow I forgot how bad it was.
Now in my scenario there is the main duct which is long like and L and then a very long run off the end total distance from furnace on this run and after every other exit is about 65 maybe 70 ft, in a scenario less extreme might be less noticeable?
