An air filter housing includes an inner housing space adapted to receive an air filter element. The air filter housing includes a first end and a second end located axially opposite the first end in relation to the inner housing space, and an outlet channel path extending from the inner housing space and out from the second end, the outlet channel path having a length X m, the length X m being adapted to stabilize a noise having a wavelength of Y m travelling through the outlet channel path towards the inner housing space, wherein the length X m is related to the wavelength Y m according to the following relationship: Y/16<X<Y/8.
