DAR Respiratory Filters & Airway Accessories

DAR is Cardinal Health's respiratory line of heat and moisture exchangers (HMEs), breathing filters, and airway connectors used in anesthesia, ICU ventilation, and pediatric respiratory care. Clinicians choose DAR components because they protect the patient's airway from cold, dry gas while helping to conserve heat and humidity that would otherwise be lost during mechanical ventilation.

The core question buyers ask here is fit: HMEs and filters are matched to a patient's tidal volume and the internal dead space they add. That's why this range spans neonatal, infant-pediatric, and adult options rather than a one-size approach. The Cardinal Health DAR Flexlife Heat Moisture Exchangers with Connector (353U5908) feature a flexible extension that eases circuit positioning at the patient connection, reducing traction on the airway. For smaller patients, the DAR Infant-Pediatric Electrostatic HME Mechanical Filters (355U5427) pair moisture retention with electrostatic filtration in a low-dead-space design suited to fragile pediatric lungs.

Connection integrity matters just as much as filtration. The DAR Double Swivel Connector (331U5661) allows the breathing circuit to rotate freely, preventing kinking and tube pull when a patient is repositioned or turned — a small piece that meaningfully reduces circuit disconnections and airway trauma.

When selecting a DAR product, confirm the standard 15/22 mm circuit compatibility, check the moisture output and filtration efficiency against your protocol, and verify the intended patient size. Most items are single-patient-use and should be replaced per your facility's infection-control schedule. If you're ordering for a unit, note case quantities so filter stock keeps pace with ventilator census.
