Features 2H Technology™, a patented filter system that consistently achieves high levels of efficiency
by combining hydrophobic and hydrophilic media to remove moisture and particulate from airflow.
Virus and bacterium, absent moisture for growth and transmission, are isolated and contained within
the system.
 

Independently tested and validated to have viral and bacterial filtration efficiencies of greater than
99.99% at a particulate size of 0.027 microns, with virtually no drop in differential air pressure.  

  Proven through extensive individual and competitive product testing to provide unsurpassed protection
from potentially harmful pathogens. 
  The patients exhaled breath is filtered and then diverted through large exhalation ports down and away
from the rescuer.
  The housing is sonically welded, not snap fit, to fuse the edge of the one-way silicone duckbill valve to
the inside edge of the housing.  This process effectivel  eliminates pathogenic avenues to the caregiver
and creates a truly sealed one-way conduit from the caregiver to the patient.
  The filters have an enlarged surface area to increase relative fltration efficiencies.  Sealed within the
sonic welded housing, they are configured to filter airflow in both directions to provide maximum
protection for both caregiver and patient.
  The one-way silicone duckbill valve remains closed while the patient exhales to prevent any back-flow
of breath to the caregiver or clogging of the filtersystem when the patient regurgitates.
