MERV 13 for Make-up air?

We have a Cafeteria-Restaurant space complying with 62.1 throughout an exhaust system with make-up air directly from the outside. All others regularly occupied spaces within the building are using a DOAS with MERV 13 filtration media. Does the make-up air for the Cafeteria-Restaurant need to be filtrated using MERV 13? Thanks in advance

Esteban, It would be safe assume so. We have a similar project and are providing MERV 13 filters on the kitchen make up air system.
