BMW 440i Cabin Air Filter Replacement at your home or office.

How important is this service?

When you turn on the heat, fan, or air conditioning in your vehicle, the air that enters the cabin is taken from outside the car. Before passing through your vents it first goes through the cabin air filter, which captures much of the dust, dirt, and harmful pollutants in the air. A functioning cabin air filter assures that the air coming through your vents is clean. When the cabin air filter stops working, the air that enters your vents is unfiltered and can be harmful to breathe. A dirty cabin air filter also obstructs the flow of air to the vents, which will lower the power of your heating or air conditioning system.
