Review on Mann Filter CUK 2533-2 🚗 Carbon Cabin Filter with Enhanced Activation by Jonathan King

Perfect fit! No slack, won't fall out, and don't need to be held when changing. No more musty smell when the air conditioner is on. A full overhaul will likely require the air conditioning to be cleaned, but they replaced the original factory filters so they still needed to be replaced. More expensive than some of the other "similar" filters at Revain, but there have been complaints that they don't exactly fit. This is still a lot cheaper than direct through BMW.
