What is the filtration accuracy of polytetrafluoroethylene microporous filter membrane?

The filtration accuracy of polytetrafluoroethylene (PTFE) microporous filter membrane varies due to its application field and manufacturing process. Generally speaking, the filtration accuracy of PTFE microporous filter membrane ranges from 0.02μm to 10μm, but the specific value may vary depending on the product specifications and manufacturers.

In the field of air purification, PTFE microporous filter membrane is usually used to filter tiny particles in the air, such as PM2.5, bacteria, viruses, etc. Its filtration accuracy is generally high, which can reach between 0.03μm and 5μm, or even higher. This high-precision filtration capability makes PTFE microporous filter membrane widely used in air purifiers, which can effectively improve indoor air quality.

In the field of liquid filtration, PTFE microporous filter membrane is used to filter impurities such as suspended matter, colloids, bacteria, etc. in water. Its filtration accuracy is usually between 0.1μm and 10μm, and the specific value depends on the design and application scenario of the product. In occasions where high-purity water quality is required, such as biomedicine, electronics industry and other fields, PTFE microporous filter membrane has been widely used for its high filtration accuracy and stable chemical properties.

In addition, the filtration accuracy of PTFE microporous filter membrane is also affected by factors such as its pore size distribution, porosity, and membrane thickness. Therefore, when selecting PTFE microporous filter membrane, it is necessary to determine the appropriate filtration accuracy and product specifications based on the specific application scenarios and filtration requirements.

In general, PTFE microporous filter membrane has a wide range of filtration accuracy, which can meet the filtration needs of different fields and different application scenarios.
