The most effective way to control the spread of airborne respiratory diseases is to stop it right at its origin. For the majority of mechanically ventilated patients, this origin is the interface to the ventilation equipment. Clinical and infection control experts have recommended pleated hydrophobic breathing system filters for controlling the airborne spread of infectious disease. Laboratory tests have shown that Pall Breathing System Filters retain airborne viruses and bacteria with an efficacy greater than 99.999%. Pall Breathing System Filters have also been shown to retain liquid-borne viruses and bacteria at 100% efficiency. Pall offers you extensive documentation on its Breathing System Filters and their capacity to provide high levels of protection against cross-contamination and cross-infection with both airborne and liquid-borne viruses and bacteria.
