MERV filter rating for CAB Air Filters

[ Edited ]

Good morning,

 

I was wondering if anyone knew how the CAT's efficiency ratings (standard, high, and ultra) compared with a MERV/HEPA scale. Our work comes in contact with silica dust which recommends having a filter with a 16 MERV rating.

 

I haven't be able to find information that compares the two rating systems.

 

Thanks,

Andrew
