The filtration grade of dust filter cartridges
Jul 28, 2025
The filtration grade of dust filter cartridges is usually expressed in microns (μm), and the specific value depends on the type of filter material and the design structure:
Conventional polyester filter cartridges :
The filtration accuracy is generally 5-10 microns, suitable for large particle dust removal such as woodworking and construction dust.
Membrane filter cartridges (such as PTFE microporous membranes):
The accuracy can reach 0.5-1 microns, and it has a significant effect on fine particles such as PM2.5.
Nanofiber filter cartridges :
Using electrospinning technology, the maximum accuracy can reach 0.3-0.5 microns, suitable for precision processing.
Typical applications in different industries
Metal polishing :
1-3 micron membrane filter cartridges are recommended
Pharmaceutical production :
0.5-1 micron nanofiber filter cartridges are required
Coal-fired boilers :
1-2 micron anti-static filter cartridges are recommended
