What does a BMW cabin filter do?

You may forget an important aspect called the cabin filter because you have to think about some aspects of your car. If you are not familiar with this part of your car, you are on the right page. This article details the features of BMW’s cabin filters.

BMW cabin filter function

During operation, the cabin air filter draws in clean air. Like the engine air filter, it serves to filter out dust and debris. If the filter is working properly, the air in the BMW cabin is free of dust.

Separately, this component ensures that the radiator, fuel line, and engine are free of contaminants.

Change the filter

As with the engine filter, we recommend that you replace the cabin air filter on a regular basis. If not changed for an extended period of time, it will adversely affect HVAC performance and the level of comfort while driving.

Apart from this, if this filter is not replaced, it will adversely affect the vehicle’s air conditioning system. The result is poor HVAC performance and increased allergens. Besides, you may find it difficult to cloud your windows.

Signs that the cabin filter needs to be changed

Based on the BMW model, it is recommended to replace this filter after 12000 miles. As a general rule, we recommend that you replace this component at least once a year. However, there are many factors to consider when making this decision. Filters are replaced more often, to name a few, based on road conditions, driving habits, and HVAC system conditions.

If you notice that the air conditioning system is not functioning properly, you may need to replace the filter.

Other signs to watch out for

If you notice that the air flow in the cabin is reduced even after raising the fan, the filter may be clogged. Also, if the HVAC system smells bad, whistles from the air intake, or if the HVAC system does not produce enough cold or hot air, it is recommended that you check and replace this part.

When operating in extreme temperatures, such as in the desert, it is advisable to replace the cabin air filter more often. Similarly, if you drive a contaminated area on a regular basis, you will need to replace it more often.

Take away

If you want to get the most out of BMW, we recommend that you perform regular maintenance. This includes changing the cabin air filter, changing the engine flash, changing the breaker display, and changing the oil. Hopefully now you understand the importance of this part of your car. We recommend that you replace this part regularly for the HVAC system to function properly.
