Details of Capnography Water Filter

Quick Details of Capnography Water Filter

Adaptable to sidestream EtCO2 sensors for gas pathway integration, it effectively purifies the sampled gas, enabling the sidestream EtCO2 sensor to accurately and swiftly collect end-tidal carbon dioxide values while protecting the gas pathway. This is a disposable consumable.

Applications of Capnography Water Filter

Maintaining the Accuracy and Longevity

A capnography filter or ETCO2 filter plays a critical role in maintaining the accuracy and longevity of capnography monitoring devices.


  1. Prevents Moisture Interference: The capnography filter blocks excess moisture from reaching the capnograph machine, ensuring accurate ETCO2 readings during continuous capnography monitoring.

  2. Protects Equipment: By filtering out moisture, the ETCO2 filter protects the sensitive components of the capnograph machine from damage, improving its reliability and lifespan.

  3. Enhances Measurement Accuracy: The capnography filter helps provide consistent and accurate CO2 levels in anesthesia monitoring and critical care, where precise ETCO2 readings are vital for patient management.

  4. Improves Patient Safety: The ETCO2 filter helps maintain clean airflow, ensuring safer respiratory monitoring for patients undergoing sedation or mechanical ventilation.
