The size of viruses is generally between 0.02-0.3 microns, dust is generally less than 75 microns, and aerosols are between 0.001-100 microns.
The diameter of dust in the air is usually 0.3-1 micron, so the PTFE air filter membrane also filters particles of 0.3-1 micron, and also plays a role in filtering viruses.
It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
