Abstract: A readily disassembled filter assembly for a carburetor air intake housing, which assembly has upper and lower plastic, metal or rubber mounting rings with annular seating grooves on the interior sides, and such seating grooves snugly but removably receive an annular foraminous flame resister support and an elongated filter element wrapped around said support. The filtering element has a substantially uniform thickness substantially greater than that of the rigid foraminous support, and said filtering element having opposite regular sides which are unbroken. The mounting rings retain upper and lower portions of the foraminous support and wrapped filter element within the seating groove, but such mounting rings may be simply pulled apart so that the filtering element may be unwrapped for washing or replacement.
