What can result from running filters to their maximum pressure drop?

Running filters to their maximum pressure drop primarily results in increased energy costs. As air filters become dirty or loaded with particles, the resistance to airflow increases, leading to a higher pressure drop. HVAC systems require more energy to push air through these clogged filters, which typically results in elevated energy consumption. This can cause additional strain on equipment and lead to higher operational costs over time.

While addressing air quality, decreased filter lifespan, and reduced maintenance requirements may have some relevance, they do not directly associate with the immediate consequences of maximum pressure drop. For instance, improved air quality is more likely to occur with clean filters rather than dirty ones. Similarly, a filter running at its maximum pressure drop can indeed decrease its lifespan because it is working harder and is likely to fail sooner due to excess strain. Reducing pressure loss typically allows for longer intervals between replacements and less frequent maintenance; however, in this context, the immediate impact of running filters to their maximum pressure drop primarily aligns with the increased energy costs incurred.
