Ultra low penetration air filters (ULPA) are mainly used for filters of 100 grades and above.
If the ULPA filters further subdivide the high efficiency filters, if the goal is to achieve the cleanliness level of 0.12µm, then the efficiency will be 0.12µm, this habit is called the ULPA filter. The filter media often use glass fiber and synthetic filter paper. The so-called HEPA Filter or Absolute Filter, its main material is glass fiber paper or chemical fiber paper (PP). HEPA filter has no clapboard according to its structural form.
ULPA filters according to its structure are without separator filters.
