A HEPA box typically refers to an air filtration unit that uses a High-Efficiency Particulate Air (HEPA) filter. These boxes are designed to remove 99.97% of particles that are 0.3 microns in size from the air, including dust, pollen, mold, bacteria, and any airborne particles with a minimum particle penetration size. They are commonly used in various environments to ensure clean air, such as in hospitals, laboratories, cleanrooms, and even in homes for improving indoor air quality.
