High-efficiency particulate air (HEPA), also known as high-efficiency particulate absorbing and high-efficiency particulate arrestance, is an efficiency standard of air filter.
Bag filters are used in HVAC applications to remove dust from ambient air. They are commonly used as final filters in commercial applications or as prefilters for HEPA filters in hospitals in the Pharmaceutical Industry.
V bank filters, also be called as v cell filters, rigid pocket filters, are the most important part in clean room ventilation systems when filtration level 100 or 10. V bank filters are pre-filters before HEPA filters, the role and function are the same as pocket filters, but v bank filters offer more stable performance.
