🌬️ Hengst E3939LC-2 Cabin Air Filter: Optimal Air Filtration for a Cleaner and Healthier Cabin Environment Review

After trying this product, my car's heating system has never been better. It warms up quickly and distributes heat evenly throughout the car. The installation process was also very easy and straightforward. The only downside is that it is a bit pricey compared to other options in the market. Overall, a great product that I would highly recommend for anyone looking to improve their automotive heating system.

These filters are exactly the same as the ones from the dealer and fit my 2014 Mercedes s550 perfectly with excellent quality.

Not as good as the OEM filter but at a much lower price. This is about 1/3 the weight (probably a lot less than activated charcoal). The triangular cutouts are not as good for a secure fit as the OEM holes. Traveling with this filter I felt a lot more exhaust fumes in the cabin. I would say if you are struggling to change the filter in an S class car you can get an OEM as well.
