I buy the cheapest ones on Rock Auto, about $5.00 and change them every June.
I've found that the cheap ones flow better. Maybe they don't filter as well but my main concern is air flow.
Heat when its 20 below zero and A/C when its a 100 degrees.
thats Colorado for you.
I don't notice any difference with charcoal/baking powder-infused filters, which is why I'm sticking with el cheapo filters from now on. The extra air flow is also a bonus.
The "carbon" is just a marketing gimmick.. at least in the capful quantities they put in them.
I own a few IQAir filters for my home that use actual carbon for odor/VOC filtration, and these work, but they have 12 pounds of carbon that costs $300 and lasts 2 years before needing replacement.
I'm actually convinced that cabin filters are of zero benefit to the passengers because dirty air leaks in through many other places. If anything, the filter just prevents the evap core from getting dirty.

Speaking of filters.. say you have a car with a filter and you switch it out to a clean one.. why is it when you turn the air on you still get a bunch of junk coming out of the vents?

The filter isn't seated properly and you're sucking built up junk from the cowl.
Or, it's an old car and that's dry-rotted bits of blend door foam coming out of the vents.
Man, you guys get great deals south of us! I paid $29.99 for one of these for my wife's new Chev Impala. Truth be known, I thought most manu's gave these up a few years ago based on data that most never changed them out? Regardless, while looking up an engine air filter, I seen our new to us car had one. I personally like the fact it has one.
My '11 Tahoe wasn't built with one. RA had a retro fit kit for it. What a big reduction on interior dust like on the dash, etc. .
I was surprised filter was not OEM on a late model expensive vehicle, my old '00 Sable and up had them.
I suppose omission of a CAF is a butch truck thing. Hey, look how much they reduced the cost of your truck! (Ha-Ha)
My friend's 1997 F-150 has a bit of the glovebox floor (either a depression or raised section) which is to be removed (cut out) as part of a CAF retrofit.
Something like this for allergen reduction, sticky resin impregnated. https://smile.amazon.com/dp/B072J97LHX/_...0CW9T&psc=0
