Cabin filter OEM Honda or OEM BMW

My wife's honda hvac used to get funky smelling from sitting a lot and I started using activated charcoal cabin filters and those helped quite a bit.

My first Honda I had serviced 1 time at the dealership. $150 for cabin air filter. YouTube video. 2 minutes later changed.

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.

I’ve had my i4 for over two years. Maintenance costs have been $0 but BMW gives you three years of free maintenance. When I have brought it in, all they do is inspect the car, top off wiper fluid and replace the in cabin air filter.

Cabin air filter too.

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.

If you’re going to stock up on cabin filters for the future, get them at Honda dealership parts department. Those filters will fit better then most aftermarket filters

I've had to replace the cabin filter 2-3 times because of this problem. At first the smell would go away after replacing the filter, but eventually returns, usually when spring rolls around.

That never got replaced, the filters still look white after 2-3 years in the cars I work on, this looks 5-10 years old.

That was not replaced in the last 5000mi. If you have an itemized invoice, I would check to see if it states what part was installed.
