In dust collection applications, the MERV value has little bearing on the long-term efficiency of the system. Most dust collector filters, whether the filters are cleaned by shaking or pulsing with compressed air, reach a steady state operating condition within the first couple hundred operating hours. A layer of dust builds on the surface of the filter, creating a dust cake that will typically remain on the filter through its entire useful service. This dust layer makes the filter more efficient than the stated MERV value, in effect, negating the purpose of the rating in many instances.

What is important in most dust collection applications is that you are using the correct filter media, the correct amount of media, and the correct configuration to allow for proper cleaning of the filter. When a dust collector system fails, it's more commonly one of these factors that lead to its failure, rather than the MERV rating of the filter.
