MAXFLOW AIR FILTER KITS FITS STIHL 044, MS440 -- INCLUDES CAGE AND 2 FILTERS

MaxFlow Filters are the ONLY aftermarket filters that are 100% USFS approved. Don't risk being shut down on Forest Service property.  Reference the (MSE) SAG HS type A. 

MaxFlow air filters trap the smallest particles while flowing twice as long as stock air filters.  This helps your saw breath better during prolonged use in adverse conditions, resulting in smoother running and more power.  Unlike pleated filters, MaxFlow filter elements are washable and  re-useable so they last longer and cost less.  Foam elements do require  the use of foam filter oil (sold separately).

For 30 years MaxFlow filters have featured only ONE  PIECE elements with no glued seams to fall apart.  No seams mean longer lasting elements with no chance for dirt to penetrate.  Don't be mislead by glued foam where gas and vibration causes the glue to fail.

Replacement of the air filter on non HD filter equipped saws or  STIHL saws with Fleece, Flocked or Screened Air Filters will require  installation of the Stihl HD backing plate 1128 124 3408, also 1128 120 2201 and other parts (not  included).
