What is microfilter bmw?

A microfilter in a BMW refers to the cabin air filter, also known as the pollen filter. It is an essential component of the vehicle's ventilation system and is responsible for filtering out dust, pollen, and other airborne particles from entering the cabin.

The microfilter is typically located behind the glove compartment or under the hood near the windshield wipers. It is recommended to replace the microfilter every 12,000 to 15,000 miles or approximately once a year, depending on driving conditions and air quality.

Regular replacement of the microfilter ensures clean and fresh air circulation inside the vehicle, prevents odors, and helps maintain the overall performance of the air conditioning and heating systems.

When replacing the microfilter in a BMW, it is crucial to use genuine BMW filters or high-quality aftermarket filters designed specifically for BMW models. Using the wrong type of filter or a low-quality filter may compromise the filtration efficiency and potentially cause damage to the ventilation system.

Overall, regularly replacing the microfilter in a BMW is an important maintenance task to ensure optimal air quality and comfort for the occupants, as well as to protect the vehicle's ventilation system from potential issues.
