(3 mm) dia. nozzle at least 2” (5 cm) away from the filter. Don’t shoot the air in a crisscross motion against the grain of the
Washing
As a last resort, wash the filter. However, do so only if the pressure drop is too high from fine dirt embedded in the filter, or if oily mist is present near the intake air location.
