Disposable Bacterial and Viral Filter
Disposable Bacterial and Viral Filter is used for bacteria, particle filtration in breathing machine and anesthesia machine and to increase the gas moisture degree, also can be equipped with pulmonary function machine to filter the spray with bacterial from the patient. Hisern’s Bacterial/Filter media was tested to VFE Efficiency 99.99% and BFE Efficiency 99.999% ASTM Standards by Nelson Laboratory. Filter efficiency may vary during use and should be replaced if filter becomes visibly soiled, resistance to flow reaches an unacceptable limit or after 24 hours of active use.
