Currently, standards and guidelines from multiple organizations recommend the use of high-efficiency air filter panels (High-Efficiency Particulate Air Filter; HEPA Filter) or Ultralow-Penetration Air Filter (ULPA) to remove airborne contaminants and pathogens, due to their ability to eliminate airborne impurities with the highest efficiency available.
Modern air filter panels are available in a variety of media materials, each with different particle-filtration capabilities, lifespans, and suitability for different applications.
For air-conditioning systems where air quality control is necessary, it is recommended to use air filter panels made from filter media fibers formed into a panel. This type of mechanical filtration captures particles in the air effectively. A high-efficiency air filter panel (HEPA Filter) is capable of filtering airborne particles sized around 0.3 microns, which are very small. During transport and installation, unexpected incidents may cause damage to the filter panel or improper installation; therefore, to reduce the risk of airborne pathogen spread, leakage testing of the filter panel is recommended.
