A protective air filter intake hood with an air deflecting intake screen for internal combustion engines and other air-aspirating machinery, the protective screen which covers the air intake opening having a series of slats forming intake flow gaps inclined at an acute angle to a horizontal vector line, so as to force the intake air to execute a change in flow direction of more than 180 degrees, in order to enter the intake duct, thereby ejecting heavier-than-air matter from the intake air.
