What is the MERV rating for dust collector filters?

Dust collector cartridge filters come in a range of filtration efficiencies (MERV ratings) for various applications. The higher the MERV rating, the more efficient the filter will be at collecting smaller particulate. (Note that all dust collector filters will approach a MERV 16 rating as they form a dust cake with use.) RoboVent cartridge filters are available in MERV 11, MERV 15 and MERV 16.
