1. Improve filtration efficiency: PTFE coating can improve the filtration efficiency of HEPA filter paper. Due to the non-sticky and microporous structure of PTFE, it is well able to capture tiny particles, including bacteria, viruses and other contaminants.

2. Increase moisture resistance: PTFE has excellent hydrophobic properties, so HEPA filter paper used in humid environments can increase moisture resistance by applying PTFE coating. This helps prevent the filter paper from absorbing moisture and reducing filtration efficiency.

3. Improve chemical resistance: PTFE is a chemically inert material and does not react to most chemicals. Therefore, applying PTFE to HEPA filter paper can make it have good chemical resistance, thereby resisting erosion and damage from chemical substances.

4. Reduce pressure drop: PTFE coating can reduce the resistance (pressure drop) of the filter paper, making it easier for air to pass through the filter paper. This helps reduce the load on the system’s fans, improving fan efficiency and reducing energy consumption.

5. Increase filter paper life: PTFE coating can reduce particles and contaminants adhering to filter paper, thereby extendingHEPA air filter paper service life. This means less frequent replacement and very low maintenance costs.

It should be noted that the application of PTFE coating may increase the cost of HEPA filter paper and requires special processes during the manufacturing process. In addition, since PTFE is non-sticky, care must be taken during handling to avoid damage to the filter paper.

Overall, PTFE coating can improve the performance and reliability of HEPA air filter paper, especially for wet environments and chemical Material-sensitive application scenarios. However, actual needs, budget and specific application requirements should also be considered when selecting and using them. Interested parties are welcome to enter the store and contact us.
