Potential application of Air Cleaning devices and personal ...

Air cleaning devices where the primary principle of operation is based on fibrous filtration or germicidal UV (UVC) are likely to be beneficial if deployed correctly (medium confidence). These devices are recommended for settings where the ventilation is poor and it is not possible to improve it by other means.

COMMERCIAL KITCHEN VENTILATION DESIGN GUIDE

The secondary recommendation in reducing MUA flow is to take credit for outside air that must be supplied by the HVAC system to meet code requirements for ventilating the dining room. Depending on the architectural layout between the kitchen and the dining room, it may be practical to transfer some of this air from the dining room to the kitchen.

Effective secondary ventilation can be established only if the primary ventilation system itself is adequately designed and operated. The two systems are in fact an integrated whole. An unbalanced primary and secondary combination can cause re-circulation, which is inefficient and potentially hazardous.
