EPA, HEPA, and ULPA Filters are high-efficiency particulate air filters designed to capture fine and ultra-fine airborne particles with reliable performance. EPA filters are used for efficient removal of dust and microscopic contaminants. HEPA filters can remove 99.99% of particles as small as 0.3 microns, and ULPA filters can achieve a filtration efficiency of over 99.999% for particles in the 0.1–0.2 micron range. They are widely used in cleanrooms, laboratories, hospitals, air handling systems, and industrial environments, and are compatible with all industry-standard FFU brands.
