Many glass fibers are used, and chemical fibers are gradually being used. At present, some foreign manufacturers use electrostatically charged polytetrafluoroethylene fibers (electrets) to make high-efficiency filters, commonly known as PTFE.
Detailed introduction

Filter characteristics:

Many glass fibers are used, and chemical fibers are gradually being used. At present, some foreign manufacturers use electrostatically charged polytetrafluoroethylene fibers (electrets) to make high-efficiency filters, commonly known as PTFE.
National standard GB / T 13554-2008 "High efficiency air filter", GB / T 6165-2008 "High efficiency air filter performance test method efficiency and resistance", high efficiency filter sodium flame method efficiency is:
  1. Class A high efficiency filter, the sodium flame method efficiency under the rated air volume should not be less than 99.9%
  2. Class B high efficiency filter, the sodium flame method efficiency under the rated air volume should not be less than 99.99%
  3. Class C high-efficiency filter, the sodium flame method efficiency under the rated air volume should not be less than 99.999%
The former refers to general high-efficiency filters. In contrast, foreign countries generally define the efficiency of high-efficiency filters as ≥99.97%.
The latter refers to ultra-efficient filters.
Now the internationally used detection method is the DOP detection method, and the detection is more accurate.
