The combined performance of Covidien's high-quality DAR™ Electrostatic Filter and an HME reduces set up time, dead space and weight on endotracheal tubes, creating a more efficient respiratory circuit. DAR Electrostatic Filters work via a hygroscopic membrane that traps moisture and provides ample humidification. They are supplied in individual, sterile packages for convenience and reliability. You can choose between two sizes, Small and Large. Click on the dropdown to the top right of the page.
