That answer is only partially true. The real answer is it depends on your system. There are modern systems that can self adjust the air flow rate to accommodate higher merv filters. However, if you're unsure what system you have, the safest bet is to go with a lower merv.
Hopefully these don't collapse. I once bought a batch at Home Depot, and it was horrible, several of them folded leaving open gaps.
Never. The higher the merv rating also the harder it makes your system works. You just buy the cheaper merv rating 2-3 and replace money without ruining your system

Actually, for systems with combined A/C coil & gas furnace the residual dust drops out on the furnace elements which sit first in the path of the returned air, and does not get to the AC coil. First time in the season the heater air usually smells of burnt dust. The AC coils are usually washed by the condensed water anyway, which drains away.
The biggest regret here is the smaller surface area because the filter is not pleated. But replacing these filters slightly more often should do the trick. Ideally one wants 5 inch thick pleated filters, but those cost an arm and a leg.
This pronoun knows what pronouns's talking about. The same thing happens with the electric resistance strips on "heat pump" units. Spray some aluminum-safe (purple) Simple Green on your A-coil and whatever dust made it through whatever filter will rinse off with it.

I'm fine with cheap high flow filters but look at the pictures in the reviews before buying! These are a thin film, not 1 inch thick fiters!
Also true. The problem with finding good fiberglass filters is these garbage ones with floppy "L"-shaped frames took over years and years ago.

Spending more money on an AC unit makes it an air purifier!
You should really spend some time learning about ductwork sizing (and installation quality), CFM requirements, and static pressure drop, and how they apply to your individual situation. Just because you have an ECM blower doesn't mean that it is optimal to have it pulling enough current to suck a grapefruit through a straw barely keeping the heat exchanger at operational temperatures.
these single ply fiberglass filters are trash and overpriced. and they are those stupid floppy "nested" versions. don't even bother
we do use fiberglass filters in all of our HVAC units, but we use the spun fiberglass 2 ply version (has 2 separate layers of spun fiberglass). filters get swapped once a month on the 1st of the month as good habit and practice
home depot used to have trueblue spun fiberglass filters for $1 a pop, they don't carry those trueblues anymore in the regular sizes, they have a different brand and the price has gone up a bit since then they are $1.25-$1.50 now depending on the size
The Pamlico airfilters at Home Depot are like $1.50 per and you buy as many or as few as you want.

Home Depot finally ditched those stupid green Flanders nested ones
and started carrying the PamlicoAir full frame 2-ply spun fiberglass filters. they are rock solid and cheap
Does anyone use reusable filters? We had some in our last house 15-20 years ago. I'd wash them and they seemed to work fine. Haven't researched them and wondering if they are recommended?
I have to run these low merv in my furance cause the dorks didn't install enough return vents so it over heats if it doesn't get enough air flow.
Stocked until the furance goes I guess!
An overheating forced-air furnace could be a sign of a bad heat exchanger.
The design/implementation could also be a factor, as you stated.
It took 3 different techs from a local HVAC to figure that out on ours.

You can also tape the perimeter of the filter with painters tape. That will not only keep the filter in place, but it forces all the air to go through the filter. And if your filter smacks against the frame when the air turns on, this will hold it in place.

Yeah, filters folded from air waves when the AC was turning on and off. Filters were seated properly. Same filter type was OK from several batches, then for 1 batch all hell broke loose - and that was the last batch for me!
That's an old fixed air handler, it does a strong air shock when turning on.
Since then I was using pleated cheap ~$3 3M filters from Lowe's (never had an issue with these filters folding), but these current ones are even cheaper, although a bit worse since they are not pleated.
I received mine today and I echo many other comments... these are not an inch thick... they are only a thin layer and rest is ... air. The filters don't even hold shape... didn't expect this from 3M. If you have not bought it... then please go to the store and see one before you buy. That might change your mind or you know what to expect.
This may not be the place buy I have a question. We have air returns in every room. And a main 16x25. Is it okay to leave them on longer than 3 months? Because of the huge amount of area filtering air, they are barely dirty then
This deal has turned into a small nightmare. Lowes cancelled 2/3 of the order and shipped 1/3 at the original price plus shipping. They refuse to refund and been on the phone for 30+ minutes arguing.

A bit late, but: normally the air filter is in the HVAC 'tower' so it doesn't matter how many air returns you have.
Quite nice (but odd) if you do have a bunch of returns. Are you sure the are returns? Usually it's just the outputs in each room. If you have at least 2 grates, and typically in different locations (ie. floor vs. ceiling)... well, that would be really cool and smart.
I did live in one house, and it was a new build in ... '93 ... where there were a return on each floor and the filters were behind those gratings. They were on the ceiling so required a ladder, but it was really nice to have it set up that way.
If you have several full size filters then it would make sense that you could replace them less often. If you have one 24x24 and (for easy math) 4x 12x12 filters, that's double the area so you could likely replace them 1/2 as often. However, if you've got 4x 12x12 filters, then you really have a 'normal' filter cross-section and should replace them as often (at something like 4x the cost, likely...)
So... the question is what size filter should your unit have? You may be able to find that in the manual, or look at the unit since it likely has a space for a filter even if it's unused.

I gather this is really prevalent in areas of the country where AC is not, and "furnace filters" are for "furnaces". I had someone stand outside their house in 95 degree weather and swear up and down that they didn't have AC, that sheet metal box with the fan on top that sat outside their house was their "furnace" (these houses were built with hydronic forced air heat.)
Our 2.5 ton heat pump (AC) needs 750 - 1000 CFM of supply air in cooling mode, depending on humidity. A 16 x 20 air handler filter is (less than) 2.22 square feet, so air would need to flow through that filter at 350 - 450 feet per minute. That's asking a lot out of a filter, and so instead we have "return grille filters" totaling around 3.9 sq-ft that flow 200-250 fpm. Pleated filters have more surface area than a flat panel, lowering that even more.
So glad I found this. My girlfriend just picked up a 4-pack of Kirkland filters at Costco for $25. This was $59.04 for me (with military discount) before tax. Crazy.

here is what we use:

we also sometimes buy them in large bulk cases from the local HVAC supply store. price is similar to home depot now and quality seems the same.

I forgot once and on week 5, my pilot light fried trying to light up without an airflow.
The whole change once every 3 months thing they advertise isn't for thin filters like this.
