General Information

To help you minimize filtration challenges, we offer a comprehensive line of high-performance breathing filters. Each Ambu aFlow filter provides its own set of unique advantages to maximize the clinical outcomes for filtration when used with multiple ventilator applications, such as noninvasive, invasive or anesthesia procedures.

In mechanically ventilated patients, the upper airways are mainly bypassed by an artificial airway thus, unlike during normal breathing, inspired gases are not filtered before reaching the lungs. Microorganisms which could be expelled by the patient in the form of aerosolized droplets or as sputum, should be prevented from entering the breathing system therefore it is recommended to place breathing filters at the Y-piece, or at the distal expiratory limb of the circuit to provide a barrier against bacteria, viruses and patient secretions, preventing cross contamination and protecting the equipment. Breathing filters should also be used as protection mechanisms against contamination of a hot water bath humidification systems. Ambu aFlow electrostatic breathing filters feature hydrophobic membranes.
