HEPA (High Efficiency Air Filter) ULPA Ultra High Efficiency Air Filter

The abbreviation for HEPA (High Efficiency Particle Air) is a name obtained through rating, which represents a high-efficiency air filter. If only 3 or fewer particles out of 10000 pass through the filter, this type of filter becomes a HEPA air filter. It uses physical aperture filtration technology to achieve the filtering effect.answerThe filtration efficiency of suspended particles can reach 99.97%, and it has good filtration effects on chemical smoke, bacteria, dust particles, and pollen. The main filtration sources include bacteria (0.3 μ m), pollen (7-100 μ m), plant spores (9-100 μ m), sawdust (0.03-10 μ m), cooking fumes in the home environment (0.3-30 μ m), cigarette smoke (0.01-1 μ m), etc. This HEPA filter is mainly used in process clean rooms, hospital wards, or some high-end household air purifiers.

The filter material of HEPA (High Efficiency Air Filter) is mainly composed of glass fiber mixed filter paper. With the development of technology, people have developed another type of ULPA filter, which has a filtration efficiency of over 99.99995% for 0.1 μ m particles. Compared with HEPA, ULPA has a compact filter material structure and higher filtration efficiency; This ULPA type filter is mainly used in the electronics industry. Other industries generally do not require such precision air filters.
