Low-Cost Hydrophobic CO2 Sampling Line Filter - China Suppliers & Factory for Bacteria Filtration
Product Introduction
CO2 Sampling Line Filter as the name indicates, is designed for integration with etCO2 sampling lines in capnography monitoring systems. The disposable filter from us consists of two pieces of housings sealed around a filtering hydrophobic membrane, which acts as a sterile barrier. The housings are made of medical grade ABS, and the filter media incorporated is a custom-made hydrophobic PTFE membrane filter which features two-side 0.2μm PTFE material providing the right combination of airflow, bacterial retention and liquid barrier capabilities.
In gas sampling lines, these filters ensure gas sample purity, prevent waste of anesthetic gases and accurately measure CO2 level, providing precisely tuned filtration to CO2 monitoring and sampling while simultaneously protecting both the monitoring equipment and the patient from potential contamination.
The hydrophobic bacteria filters from us are Class 100,000 cleanroom manufactured with fully automated assembly technology, and the sealing is done without any glues or solvents - they are ultrasonically welded. And the inline Anti-Microbial filters are available with Male/Female luer lock connectors, each connector meets the ISO standard for connections, thereby guaranteeing compatibility and safety across a wide range of medical devices. Each and every piece of the micron filter for a bulk order is tested by our advanced machines and inspected manually and final-tested for technical parameters in our own laboratory before packaging and delivery to guarantee superior and consistent quality.

Applications
The hydrophobic filter is designed and manufactured in such a way that they can be used safely for various clinical situations that would require a bacterial filter. And the single-use filter device can be attached to most cannulas with male and female luer lock connectors. These filters allow you to vent out air or other gases while retaining the water-based fluids that will be used to aid in the treatment of patients, therefore are commonly used in air vent functions within medical devices including:
- EtCO2 (Capno) Sampling Lines: Gas sample purity
- Intravenous lines: Inline air venting
- Hemodialysis lines: Pressure transducer protection
- Breathing Systems: Breathing circuit sterilization
- Most cannulas & pressure flow, snore sensors
Packing Details
6000pcs/carton containing 3 inner PE bags with 2000 pcs each. Each bag is sealed individually with protective air cushion between each other. Each bag is labeled with necessary information, and different lots in one carton are wrapped and labeled separately to prevent mix up.
Frequently Asked Questions (FAQ)
What is the main purpose of a CO2 Sampling Line Filter?
It is designed for integration with etCO2 sampling lines in capnography monitoring systems. It acts as a sterile barrier, ensures gas sample purity, prevents waste of anesthetic gases, and accurately measures CO2 levels while protecting both monitoring equipment and patients from potential contamination.
What materials are used to manufacture these filters?
The filter housings are made of medical-grade ABS, and the filter media incorporated is a custom-made hydrophobic PTFE membrane filter featuring a two-side 0.2μm PTFE material.
Are these inline filters compatible with standard medical devices?
Yes, they are available with male and female luer lock connectors. Each connector meets the ISO standard (compatible with GB/T 1962.2-2001 / ISO 594-2) for connections, guaranteeing compatibility and safety across a wide range of medical devices.
How is the quality and safety of the filters verified?
They are manufactured in a Class 100,000 cleanroom using fully automated assembly and ultrasonic welding technology (without glues or solvents). Every single piece is tested by advanced machines, manually inspected, and laboratory-tested for technical parameters before packaging and delivery.
What clinical applications are these filters used for?
They are commonly used for air venting functions in medical devices, including EtCO2 (Capno) sampling lines, intravenous lines (inline air venting), hemodialysis lines (pressure transducer protection), breathing systems (circuit sterilization), and most cannulas, pressure flow, and snore sensors.
How are the filters packaged for bulk delivery?
They are packed with 6000pcs per carton, containing 3 inner PE bags with 2000pcs each. Each bag is individually sealed with protective air cushions, fully labeled, and different lots are wrapped separately to prevent mix-ups.
