    Abstract: A method of cleaning one or more air filter elements with a cleaning arrangement includes a rotatable basket for holding the one or more air filters, a spraying device for spraying cleaning fluid into the basket, and a driving unit for driving the basket into rotational motion. The method includes placing the one or more air filter elements in the basket, and performing at least three cleaning cycles. A cleaning cycle comprises the following steps. First the rotation of the basket is driven up to a rotational speed at which the one or more air filter elements have a speed greater than about 15 m/s, preferably greater than about 20 m/s. Then the rotation of the basket is brought back to a rotational speed at which the one or more air filter elements have a speed below about 2 m/s. In addition, the cleaning cycle includes spraying cleaning fluid into the basket during at least a portion of the cycle.
