Covidien / Medtronic DAR Mechanical Filter

DAR™ Mechanical Filters from Medtronic are highly-efficient filters that offer excellent bacterial and viral filtration efficiency. These mechanical filters work via a hydrophobic membrane that prevents cross contamination caused by aerosolized droplets. DAR filters come with an end tidal CO2 sampling port, which offers easy access for airway gas monitoring. These filters come in three different models: Small, Compact, and Large, with an additional Large model that does not feature the end tidal CO2 sampling port.
