How do MUAs work?

The main purpose of a MUA is to provide filtered air ventilation to the inhabitants inside a building and balancing air pressure. MUA stands for “Make Up Air”, and given the name, it helps make up for all of the air that is released outdoors creating positive air pressured and minimizing negative air pressure. Positive air pressure is important because it helps regulate odor, helps minimize the spread fire and helps reduce carbon monoxide levels, therefore making a MUA, a critical HVAC component in any building.
