Three separate layers of hydrophobic and hydrophilic filter media to remove moisture and particulates from exhaled breath. Bacterium and virus, requiring the presence of moisture for growth and transmission, are isolated and contained within the system.
Independently tested and validated viral and bacterial filtration efficiencies of greater than 99.99% at a particulate challenge size of 0.027 microns.
Sonically welded to fuse the edge of the one-way silicone duckbill valve to the inside edge of the housing. This process effectively eliminates pathogenic avenues to the caregiver and creates a truly sealed one-way conduit from caregiver to the patient.
The filters have an enlarged surface area to increase the relative filtration efficiencies. They are sealed within the sonic welded housing and configured to filter airflow in both directions, providing maximum protection for both caregiver and patient.
The patient’s exhaled breath is filtered and then diverted through large exhalation ports down and away from the rescuer.
The one-way silicone valve remains closed while the patient exhales to prevent any back-flow of breath to the caregiver or clogging of the filter system when the patient regurgitates.
The deluxe facemask provides a comfortable, airtight one-handed seal. The fixed dome does not collapse, ensuring effective an reliable positive pressure on the patient's face.
Over 7 inches tall to maximize separation between the caregiver and patient and provide a superb line of sight.
