Cabin filter OEM Honda or Fram
I have a Honda Jazz/Fit ss a runabout. At about 5 years old it started fogging, despite having clumate control always on.
I found that the cabin air filter was filthy. ( despite it supposedly being changed at dealer services)
I changed the filter in minutes, having bought one on Amazon.
Problem solved.
Cabin air filter too.
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.
i finally got around to doing the cabin filter in my old beater accord... i seriously doubt it was ever changed after it rolled off the line 22 years ago. it was basically black, and it wasnt a charcoal filter lol. a bunch of ripped insulation on top, so one of the previous 13 owners had some mice in their garage. it made a total night and day difference in airflow and temperature, i think the fan dial has 8 stops and the 2nd one feels like what it was on max before. cranking it now feels like a wind tunnel in comparison, and the ac gets way colder now.
FRAM TrueAir for me - smelled much fresher in the cabin for a little while, but nothing spectacular...
the cabin air filter from Honda is a flimsy low-quality part best to get one with a carbon coating. the engine air filter from honda is ok but [rockauto.com](http://rockauto.com) sells the oem equivalent and better.
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)
You don't need to buy OEM - *especially* for a cabin air filter - but you could save some money by finding a good source of Bosch or Wix filters. Never Fram, ever.
