Provide exceptional filtration in hospitals, clean rooms, and other places where you need to control airborne contaminants. The rigid frame withstands withstands fluctuations in airflow, such as those created by variable air volume systems. There's a sealing gasket on the downstream side of the filter to prevent leaks.

For a more affordable alternative to HEPA filters, consider ultra-efficiency filters. They are made for areas where absolute filtration isn't required.
