Carefusion 001851 - AirLife Bacterial/Viral Retentive Filter Nonconductive, 22 mm ISO Connectors, Disposable, Latex-Free, 50/CS
The Carefusion 001851 AirLife Bacterial/Viral Retentive Filter is a single-use, nonconductive respiratory filter engineered to protect both patients and equipment from cross-contamination during mechanical ventilation and respiratory therapy. Designed with hydrophobic filtration media and ISO-standard connectors, it efficiently captures airborne bacteria and viruses while maintaining low airflow resistance. Its transparent housing allows for clear visibility of internal conditions such as moisture accumulation, enabling prompt replacement when necessary. This filter is ideal for use in high-risk infection control environments such as ICUs, emergency rooms, and transport settings.

Key Features and Benefits
High-Efficiency Filtration: Captures up to 99.9% of bacteria and 99.7% of viruses, significantly reducing the risk of pathogen transmission through respiratory circuits.
Low Resistance to Flow: Designed to maintain low pressure drop (approximately 0.54 cm H2O at 1.0 L/sec), ensuring patient comfort and efficient ventilation, even over extended use.
Hydrophobic Filter Media: Prevents liquid penetration and filter saturation, reducing the potential for clogging and preserving performance during humidified ventilation.
Visual Inspection Window: The translucent casing makes it easy to monitor for condensation or discoloration that may signal the need for replacement.
Universal Fit: Equipped with standard 22 mm outer and inner diameter ISO connections, it integrates seamlessly with most adult ventilators, anesthesia machines, and respiratory circuits.
Single-Use and Latex-Free: Minimizes cross-contamination risks and is safe for patients with latex sensitivities.
