OEM quality
BMW dealer wanted $300 to replace the cabin filters. Watched a 5 minute video and ordered these up. Look identical to OEM and easiest cabin filters I've installed. Save yourself a ton of money and install these yourself. BMW quality without the BMW price.

Excellent filter! Fits my 2017 BMW X5 f15. Eliminates all external odors from the street.

Great price
I love Mann filters. Great for the price and great quality. I was surprised how cheap they were ( my car takes 2 filters and two come in the box). They fit like a glove and now I am enjoying fresh air

Can’t beat MANN quality
Bought to replace the filters on my 2015 bmw x5 as there was a musty smell from ac. Old filters were another junk company that fit very loosely. I was impressed by the quality and how secure the MANN filters locked into the housing; musty smell all gone now! Easy 10min replacement job, comes with VERY detailed instructions for the less mechanically inclined
