Cabin filter OEM Mazda or Fram

i replaced the cabin air filter on my 2016 mazda3 for ~$10, took me only a few minutes.

The Genesis OE filter is $75!! The Fram Fresh Breeze filter is $25 or less; it combines activated charcoal with baking soda to reduce HVAC odor. I've used them in all my vehicles since Fram introduced the Fresh Breeze filter line and found them remarkably effective.

I did the air box filter and cabin filter myself (Fram stuff).

When I replaced my own I typically used Fram Fresh Breeze air filters with carbon. It made my car smell good more than anything.

FRAM TrueAir for me - smelled much fresher in the cabin for a little while, but nothing spectacular...

ABS or TPU? Im thinking about making somthing similar for my ND2.

Otherwise, the Fram cabin filters are fine, too.

IMO, don't get the really thick ones with carbon (like Fram FreshBreeze) - they restrict airflow and can cause the resistor and motor to overheat (essentially it's like a clogged/dirty filter)

On certain mazdas (like my 2006, 2008.5 Mazda3, and 2015 Mazda5) it's NOT a 2 min job. It requires 2-3 hr yoga session to warm up to prep for the job, then another 2hrs trying to get in the right position as to not cramp up while trying to position 2 filters on top of each other in a space that only small children hands can access

Unnecessary. A few years ago a Mazda dealership suggested a bunch of work to me when I went in for an oil change, including some stuff I had done on my own literally a week before. I got a survey from Mazda and complained on it that they were suggesting bogus things that I know for a fact did not need to be done (e.g. they claimed my cabin air filter and engine air filter were dirty, despite being brand new).
