The preVent II™ filter uses high quality electrostat® material that traps bacteria and viruses, preventing contamination to the patient, technician and equipment.

With a unique oval mouthpiece design and lip grip, the filter is comfortable to use. Designed to fit directly on the preVent flow sensor, the smart design is leak-free yet can be rotated for proper patient alignment.
