Yeah, i'm failing to see how these charcoal filters really do anything, besides reduce air flow. I'd like to see a test prove they work!
Generally agree. Would have to look at the adsorption isotherm for every stinky thing though. The higher the concentration the more will absorb usually... but it is surface and mass-limited.
And stuff will desorb preferentially as well... so it may be more of a way to "normalize" the concentrations of odors rather than remove them permanently... speculating...

ALWAYS REMEMBER: The CVAF is to protect the AC evap coil. ....but hey, if it gives you something to jeer ("How'd we get by before..." etc.), have at it.

Those people are ignorant. Activated charcoal has nothing in common with coal dust which causes lung disease in miners.

Ok, car A/C been around since '53. How did AC evap coils survive over 40 years without cabin filters?

Bigger, less efficient, more durable, more open to the environment (less spots to trap water and make mold)

I don't think the cabin air filter has anything to do to prevent mold on the evap. It's to keep allergensand dirt away from the passengers. I never had any car of mine get a moldy evap hut I do know it happens.
I've used both those filters and there is zero difference.
Amazon now sells their own amazon basics cabin filters and they are charcoal impregnated. Super deal if you get a two pack. Good luck, hopefully they have your size. If not there are a ton of options there for cheap money

And for my car, it costs more than the aftermarket OEM filter (Mann) for my car.... no thanks.

There ought to be a name for the inadequacy of or inefficiency with which lower level retailers (Walmart, "farm" stores) and local parts shops (AAP, AZ, O'Reilly's) procure parts for foreign cars.
On the Advance Auto Parts website I used a combination of sale pricing and coupons to buy a transmission filter + pan gasket for a friend's 2011 Outlander and two other parts for my Volvo.
I did it to see the machinations. Four boxes from each point of the compass. Two bore AAP labels, two from elsewhere.
I got the parts and I got the prices but I assure you, that was a one time deal.

Ask Project Farm to test!

They got rid of the car before the coil got clogged.

Charcoil air filters do work, I have Sharp home air cleaners with a reusable, washable activated charcoal element and yes it does weigh several pounds. It has a removeable filter box with a washable dust screen on top, the washable charcoal filter underneath, then a paper HEPA filter, and inside the unit an ozone generator to attract dust. It's a made in Japan unit used in hospital rooms there.
The amount of charcoal on that fits a car cabin air filter a few ounces at best, will do very little.

Not to mention how quickly these odors pass right through the filter. Charcoal isn't that "magnetic" to odor.

You get what you pay for they said.
Gotten through 75 years believing that truism isn't true.
