HEPA/ULPA Filters

These HEPA/ULPA filters were designed for a more demanding operating condition where a critically clean environment is highly required. Generally, the HEPA filter must remove 99.97% of 0.3-micron particles that pass through the filter. While the ULPA filter must remove a minimum of 99.999% of 0.1 – 0.2-micron particles that pass through a filter. This is considered the most sensitive part of air filtration to guarantee clean and comfortable air for those working in the environment.

Both filters normally share similar applications because both are used in the application that demands a very efficient filtering process of airborne pathogens. These pathogens can cause and aggravate asthma and cause allergies or diseases. These filters are also widely used in the manufacturing environment which requires very clean air. Some other applications of the HEPA/ULPA filter include airline cabin air purifiers, biomedical air filtration, electronics manufacturing, pharmaceutical manufacturing, and vacuum cleaner filters.
