Husqvarna OEM Air Filter (Nylon Mesh #44) for 435, 440 Chainsaws 599729401

Replacement OEM air filters from Husqvarna. Keep your chainsaw running efficiently with a clean air filter. These filters have a fine (44 micron) nylon mesh material on the surface that picks up sawdust and debris. This filter works well in cold cutting conditions, and is recommended when cutting in sub freezing temperatures that would ice up a felt filter. We recommend using a felt filter for extremely hot, dusty situations where a lot of fine material is encountered. These are oil-less filters. These air filters will load up quickly because of the fine mesh, so we recommend having a couple of spares handy.
