Quick question, this may be normal anyway.

Two-story home with standard Tempstar (80% eff) Furnace and AC.
Air Filter Size is 20x25x1.
I change every 2 months or so.
I use the standard filter (Merv6) that one gets from Home Depot for $4-5/each.
It has a wire mesh on one side (facing the blower). I know I install the filter correctly.

I have a quick question, peeking inside the Air Filter Slot, I notice that the Air Filter is bowed toward the blower, I assume this is normal because air is pulled through the air filter so it bows a bit (like a bow and arrow kind of thing)?
Any advices?

Mine does the same thing. I change mine once every month to month and a half just because I worry about it getting sucked into the blower.

What tonnage A/C, & what CFM is trying to go through a filter's free-air-area (Ak) - with apparently too much restriction?

Try e-z flow filters by Flanders. Them expensive filters that claim to collect more dust it restricts the air flow.

filter bowing? too much restriction or plugged or dirty. replaced. stop using 3M and change your filter monthly.

A merv6 lets plenty of air through.That is not your problem.Your return air SYSTEM is too small.The people that installed your furnace didn't have enough HVAC knowledge to fill a thimble.
You might get some relief if you lowered the speed on the blower but that might screw up your air conditioning performance.
What you need to do is find a lot better HVAC co.
