NWP Air Filter (Nylon Mesh) for Stihl 029, 039, MS 290, 310, 390 Chainsaws (Replaces 1127 120 1620)

Replacement air filters from NWP. Keep your chainsaw running efficiently with a clean air filter. These filters have a medium (80 micron) nylon mesh material on the surface that picks up sawdust and debris. This filter works well in wet winter cutting conditions, and is recommended only when fine dust is not present. We recommend using a felt filter for hot, dusty situations where a lot of fine material is encountered. These filters are oil-less. These air filters breath easier than fine mesh, but will allow fine dust particles to enter the carburetor.
