Proof of longer life, cost savings, and better air quality leads medical center to install 30/30 filters across the campus

Furnace filters case study for hospitals

The design of the inlet air ductwork and configuration of the air handling unit component spacing were causing very short filter life due to higher than normal air velocity and turbulent airflow patterns. In addition, high humidity common to the facility’s geographic location was exacerbating the strain on air filter life. The poor design conditions led to quick filter loading and frame bowing and breakage. This caused the need to change filters on average of every two months. Redesigning and replacing the air handling units would cost the center hundreds of thousands of dollars which was not an option.
