Since you have to think about various aspects of your vehicle, you can forget about an important aspect called a cabin filter. If you are unfamiliar with this part of your car, you are on the right page. In this article, we are going to learn more about the function of the cabin filter in your BMW.

Functions of a BMW cabin filter

As you drive, breathe clean air thanks to the cabin air filter. Like the engine air filter, it filters out dust and dirt. The air inside the BMW cabin remains dust-free if the filter is working properly.

Apart from this, this component ensures that the radiator, fuel line and engine are free from contaminants.

Change filters

Like the engine filter, you may want to replace the cabin air filter regularly. If you don’t change it for a long period of time, it will have a negative impact on HVAC performance and your comfort level while driving.

Other than this, not replacing this filter will negatively affect your vehicle’s air conditioning system. As a result, you will have the problem of poor HVAC performance and increased allergens. Also, it may be difficult for you to demist your Windows.

Signs that you need to change the cabin filter

Depending on the model of your BMW, you may want to replace this filter after 12,000 miles. As a general rule of thumb, you may want to replace this component at least once a year. However, you may want to consider many factors in making this decision. The frequency of changing the filter will be higher depending on road conditions, driving habits, and the condition of the HVAC system, just to name a few.

If you notice that the air conditioning system is not working properly, the filter may need to be replaced.

Other signs to watch out for

If you notice reduced airflow in your cabin even if you turn on the fan, the filter is probably clogged. Also, if the HVAC system produces unpleasant odors or if you hear a hissing sound from the air intake, or if your HVAC system is not producing enough cold air or hot air, you may want to check this part and replace it.

It is important to note that if you are driving in extreme temperatures, such as a desert, you may want to replace your cabin air filter more often. Likewise, if you drive through polluted areas regularly, it will need to be replaced more frequently.

Food to go

If you want to get the most out of your BMW, we suggest that you take care of regular maintenance. This includes replacing the cabin air filters, flushing the engine, replacing the circuit breaker screen, and oil changes. Hopefully, you now understand the importance of this part of your car. You may want to replace this part regularly to ensure proper operation of your HVAC system.
