Long Service Life: Pleated design provides high surface area and dirt holding capacity, reducing replacement frequency.
Customizable OEM Options: We offer various lengths, end caps, micron ratings, and labeling for global distributors and system integrators.
What is PTFE Filter Cartridge
A PTFE filter cartridge is a pleated filtration element made from polytetrafluoroethylene membrane, known for its hydrophobic nature, chemical inertness, and thermal stability. These cartridges are primarily used to filter aggressive gases, corrosive liquids, and sterilizing air in industries where conventional filter media may degrade or fail.
PTFE membrane filters are especially valuable in chemical processing, pharmaceuticals, semiconductors, and food & beverage sectors due to their ability to resist strong acids, alkalis, and solvents. Hydrophobic PTFE prevents water absorption, making these cartridges ideal for air and gas filtration systems.
Available in various micron ratings such as 0.1μm, 0.2μm, and 1.0μm, PTFE filter cartridges are engineered for high flow, low pressure drop, and maximum filtration performance. The pleated structure increases surface area and enhances the cartridge’s dirt-holding capacity.
With long service life, broad chemical compatibility, and sterile processing capabilities, PTFE cartridges are widely adopted in applications where consistent, reliable filtration is essential.
Key Features of Our PTFE Filter Cartridges

Frequently Asked Questions (FAQ)
Q1: What’s the difference between PTFE and PES filter cartridges?
A1: PTFE cartridges are hydrophobic and chemically resistant, ideal for gas and aggressive liquids. PES cartridges are hydrophilic, better for water-based and sterile liquid filtration.
Q2: Can PTFE filter cartridges be sterilized and reused?
A2: Yes, PTFE filters are designed for multiple sterilization cycles, including steam autoclaving and gamma irradiation. Their membrane remains stable over repeated uses.
Q3: Are these cartridges compatible with my filter housing?
A3: We offer multiple end cap configurations (DOE, 222, 226) to match most standard housings. Custom sizes are also available upon request.
Q4: How do I know which micron rating to choose?
A4: Selection depends on your application. For gas sterilization, 0.2μm is common. For chemical filtration, 0.45μm to 1μm may suffice. Contact our technical team for guidance.
Q5: What’s the delivery time for OEM orders?
A5: For custom-labeled or large quantity orders, production typically takes 10–15 working days. Stock items ship within 3–5 days.
Q6: Do your PTFE cartridges meet regulatory standards?
A6: Yes. All filters are manufactured using FDA-compliant materials and follow ISO 9001 quality systems. Validation reports and traceability documents are available on request.
