Air filter assembly for vehicles

The present invention relates to an air filter assembly, and more particularly, to a vehicle air filter assembly having a separate air filter unit that can be attached and detached in the center of the air filter assembly that is most in contact with the incoming air from the outside.

In general, the vehicle air filter is used to remove impurities from the air flowing into the vehicle or to remove impurities from the air flowing into the engine.

The air in the air flowing into the vehicle contains impurities such as dust, allergens, pollen, and dust. If the polluted outside air is introduced into the sealed vehicle without being cleaned, the driver and other occupants may not only be unpleasant, but also may have fatal health effects such as shortness of breath.

In addition, the engine of an automobile burns gasoline to move a cylinder, and the automobile engine needs a large amount of air to burn gasoline. The air entering the engine to burn gasoline contains impurities such as sand and dust.
