Cabin filter Bosch or OEM BMW

The cabin filter, Bosch (BOSCH 6092C HEPA Cabin Air Filter) is what I picked up on Amazon.

I got the Bosch one on Amazon, it claims to be HEPA. Not sure about that but Bosch tends to make quality products

Cabin Filter - Bosch HEPA 6092C. the air blowing speed is reduced though due to finer filtering so if u plan to run it in summer, u likely have to crank up the fan speed one/two level up higher than usual.

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.

Got a decent price on these quality BOSCH Hepa Cabin Filters for my 2013 SFS!

I replace mine every 10k miles on average, there is lots of dust and debris on the roads where I stay. Bosch HEPA filters (6022C) are very nice for the price, I like them

I've been using Bosch HEPA filters in my vehicles. BOSCH 6075C for the twins. I ordered a few from Rock Auto.

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.
