HEPA and ULPA Filtration

HEPA filters are engineered to deliver the highest level of air filtration available, making them essential for commercial and industrial applications where clean air is critical. Widely used in hospitals, clean rooms, pharmaceutical plants, and other environments requiring stringent contamination control, these filters ensure the protection of people, processes, and equipment.

A HEPA filter (High-Efficiency Particulate Air filter) must meet strict performance standards. According to the United States Department of Energy, HEPA filters are required to remove at least 99.97% of particles as small as 0.3 micrometers in diameter. This exceptional efficiency allows them to effectively capture micro-pollutants, including dirt, dust, pollen, moisture, bacteria, and even viruses.

HEPA filters are indispensable in spaces demanding superior contamination control, such as laboratories, manufacturing plants, nuclear facilities, and healthcare settings. Choose HEPA filtration for the ultimate in clean air protection and performance.
