An acronym for 'High Efficiency Particulate Air'. HEPA is the best known filter for removing at least 99.97% of particulates such as dust, animal dander, smoke, mold and other allergens that are 0.3 microns or larger, from the air and thus improving air quality.
This filter is ideal for most laser applications.
This HEPA filter is designed to fit the Hobarts Fume-X and Alpha 400 fume extraction systems.
