Typically used in manufacturing or scientific research where small particles can adversely affect the processes, a cleanroom is a controlled environment that has a low level of pollutants such as dust, airborne microbes, aerosol particles and chemical vapors. Cleanrooms maintain particulate-free air through the use of either High Efficiency Particulate Air (HEPA) or Ultra-Low Penetration Air (ULPA) filters employing laminar or turbulent air flow principles.
