For use with ventilators, anesthesia machines and open flow systems where filtration of inspired and/or expired gases is desired and to add, maintain, retain moisture for the exhaled breathe of the patient. Use up to 24 hours.

The Models of the filters are A501-1, A501-2, A501-3, and A501-4. The filters are intended for patient population that weighs greater than 10Kgs.

Breathing circuit bacterial/viral filter has into two models: - 1) Bacterial/ viral filters; 2) Bacterial/viral filters HME. Breathing circuit bacterial/viral filters are available in multiple sizes and shapes, rectangular and round, and incorporate standard 15/22 mm connectors with a gas sampling luer port. The depth filter use electrostatic media for filtration and a foam media for the HME media.
