Cabin filter Wix or OEM BMW

I use WIX for every car I've owned for the past 10 years. Good quality, and not overly expensive

Same issue in my 2019 M3. Replace the cabin air filter. Solved.

At 23k miles I figured a cheap fix would be the cabin filter. Swapped in a Wix WP10159 charcoal filter and the smell is gone.

I use a charcoal Wix filter. It works really nice, even for filtering out smells a bit. And I drive a lot on dirt roads and it helps clean that up too.

As for the cabin air filter. I usually go with WIX.

I went with Wix. Works well.

The HVAC smelled really musty from sitting so long, so I replaced the cabin air filter with a new Wix one.

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.

2) Cabin/engine filter ( $210) buy the filters elsewhere for $40ish. Spend the 10 min to do it at home.

One out of two times they gave me the wrong engine filter, even though they searched by VIN number. The second, and last time, I purchased from them, they sold me an aftermarket cabin filter for the same price as OEM.
