Miller 300539 Replacement Filter for MWX-D

Miller Filtair MWX-D Mobile Fume Extractor Filter

Part # 300539

Nanofiber Cartridge Filter features an ultra-thin surface webbing of tiny fibers to capture weld fumes on the surface of the filter instead of within. This extends the filter life, maintains longer lasting air flow, and lengthens your maintenance intervals. FILTAIR’s MERV 15* filter provides higher efficiency and longer filter life overall. *MERV (Minimum Efficiency Reporting Value) is between 1 and 20. A higher MERV indicates a more efficient filter and is more effective against submicron-sized particles .30 to 1.0 micron.
