What is the difference between ultra high efficiency air filters and high efficiency air filters?

There are two main differences:

1、 Different filtration efficiency:SFFILTECH ultra-high efficiency filter has a high filtration efficiency, which can act on particles and smoke detectors, with fine dust particles ranging from 0.1 to 0.2um; However, the filtration efficiency of the SFFILTECH high-efficiency air filter is slightly lower. The SFFILTECH HEPA air filter only works on particles of 0.3um, and although the filtration efficiency can reach 99.97, it is still slightly lower compared to the SFFILTECH ULPA filter.

2、 Workplace: When comparing this aspect, consider filtering efficiency. The SFFILTECH ultra high efficiency filter can withstand ISO level 3 inspection and can be said to have achieved level 1 cleanliness. However, the SFFILTECH high-efficiency air filter is relatively inferior, with a range of 100 levels of cleanliness, also known as ISO 5.

Different levels of filters can be purchased according to actual needs.
