How to identify the use of air filter cartridges

When maintaining the air cleaner, carefully check the color and contrast of the filter paper inside and outside the paper filter element. Used filter elements, the outer surface of the exposed surface of the atmosphere due to the deposition of dust, the color is gray-black; and the inner surface of the filter paper facing the inlet side of the air should still show its true colors. If the dust on the outer surface of the filter element is removed, the true color of the filter paper can be revealed, and the filter element can continue to be used. When the outer surface of the filter element is cleared of dust, its paper color no longer appears, or the inner surface of the filter paper becomes dark, the filter element must be replaced.
