Cabin Filter Microfilter Replacement BMW E90 E91 E92 E93

In this article I will show you how to replace the microfilter on BMW E90 E91 E92 E93.

The microfilter is also known as the cabin filter.

Its function is to filter pollen, dust, soot and any other physical contaminants that enters the car’s cabin, through the ventilation system.

In addition to the classic filters, active carbon filters and antibacterial filters have appeared on the market, which, although they are more expensive than the classic ones, they have the great advantage that, in addition to solid physical contaminants, they can also stop odors or gases from the environment,  and can also have an antibacterial role.

Classic microfilter

The classic microfilter is used to stop solid matters such as dust, soot or pollen.

The price of a classic microfilter is usually lower than an active carbon filter or an antibacterial filter.

Active carbon microfilter

Unlike the classic microfilter, an active carbon filter has the ability to capture dangerous gases to health, such as ozone or nitrogen dioxide, from the air, thanks to the additional layer of active carbon.

The disadvantage of such a filter is the higher price.

Antibacterial microfilter

With this mkicrofilter, protection will be maximum.

In addition to all the functions listed above, this filter has properties that can neutralize the entry of bacteria from the air into the passenger compartment of your car, as well can stop the formation of bacteria in the materials from which it is fabricated .

Replacing the microfilter

Regular replacement of the microfilter is essential, even if many of us would be tempted to neglect it, because it gradually loses its efficiency.

The replacement period of the filter differs from one product to another, but it is recommended to replace it at most once a year.
