WebThis study assessed the application of photocatalytic oxidation (PCO) to the high efficiency particulate air (HEPA) filter for disinfection of airborne microorganisms. Experiments were conducted at two TiO2 loadings (1870 +/- 169 and 3140 +/- 67 mg/m(2)) on the HEPA filter irradiated with UV-A at the intensity of 0.85 +/- 0.18 or 4.85 +/- 0.09 mW/cm(2) under two … Webelectrostatic filter: A filter that uses electrostatically enhanced fibers to attract and retain particles. filter bypass: Airflow around a filter or through an unintended path. filter face velocity: Air stream velocity just prior to entering the filter. filter performance: A description of a filter’s collection efficiency,

Web4.3 High Efficiency Particulate Air Filters. The main component of the heating, ventilating and air conditioning (HVAC) system is the HEPA filter. The HEPA filter was designed as a filter for gas masks by the United States Chemical Warfare Service. With the development of atomic energy, they were seen to be of value. WebBackground: Fine particulate matter (PM 2.5) exposure may impair fetal growth. Aims/objectives: Our aim was to assess the effect of portable high efficiency particulate air (HEPA) filter air cleaner use during pregnancy on fetal growth.
