The two-way biological filter of the O-Two CPR BioBarrier^® training face shield will prevent the passage of over 99% of the viruses and bacteria. It also acts as a physical barrier to moisture, helping to prevent the transfer of body fluids.

During CPR training, the large, pliable — yet extremely strong — face shield with graphic illustrations assists the student in correctly positioning the O-Two CPR Bio-Barrier^® training face shield.

O-Two CPR Bio-Barrier^® training face shields are packaged on a roll of 50, allowing each student to tear off her/his protective device.
