What is PES Filter Cartridge
A PES filter cartridge is a pleated filtration element made from hydrophilic polyethersulfone (PES) membrane, designed for high-purity liquid filtration. PES membrane filters are widely recognized for their high flow rates, low protein binding, and excellent microbial retention efficiency.
These cartridges are engineered to remove bacteria, particles, and other impurities from fluids in sensitive applications such as pharmaceuticals, laboratory processes, food & beverage production, and medical device manufacturing. Unlike PTFE or PVDF membranes, PES filters do not require pre-wetting, which enhances operational efficiency and cost savings.
The pleated design increases surface area, extending filter life and reducing frequency of replacement. They are typically used as final-stage filters in critical liquid processing systems, especially where sterility and consistency are essential.
Available in various micron ratings such as 0.1μm, 0.2μm, and 0.45μm, PES filter cartridges are compatible with most industry-standard housings, including 222 and 226 end caps. Whether for small lab systems or industrial-scale sterile production, PES pleated filters provide reliable and repeatable performance.
Key Features of Our PES Filter Cartridges
High Retention Efficiency: Capable of removing >99.99% of bacteria and fine particulates at 0.2μm and 0.1μm levels.

Frequently Asked Questions (FAQ)
Q1: What’s the difference between PES and PVDF membrane filters?
A1: PES (Polyethersulfone) membranes are hydrophilic and have lower protein binding than PVDF, making them ideal for biological and pharmaceutical applications. PVDF is more hydrophobic and used in aggressive chemical environments.
Q2: Are PES filter cartridges reusable?
A2: PES filters are primarily designed for single-use sterile filtration. Some applications may allow cleaning and reuse, but filtration efficiency may decline after repeated sterilization.
Q3: How can I verify filter integrity?
A3: We provide bubble point and diffusion test data for each batch. Integrity test kits are available upon request, or we can provide on-site support for validation.
Q4: Can I get customized micron ratings or lengths?
A4: Yes. While 0.2μm and 0.45μm are standard, we can produce other ratings upon request. Lengths like 5”, 10”, and 20” can be customized to fit your housing.
Q5: Do PES cartridges comply with FDA and USP standards?
A5: Absolutely. All materials are FDA-compliant and tested according to USP Class VI, <85>, <87>, <88> for biocompatibility and extractables.
Q6: What’s the MOQ and lead time?
A6: For standard models, MOQ is low (as few as 10 pcs). For OEM orders, MOQ starts from 100 pcs. Lead time is 3–7 days for stock items, 10–20 days for custom orders.
