Reusable Half-Face Mask

Filters Viruses and Bacteria

A protective barrier against contagious viruses such as Mexican Flu (Swine flu).

Comprising three layers:

v     Preliminary filter layer

v     Electrostatic layer:  filters bacteria and viruses
(NIOSH test results on this material quoted below)
BACTERIAL: 6.9X10⁶ CFU – CFU recovered = 0
Filtration Efficiency >99.99999%
VFE (VIRUS): PFU 4.2X10⁶ – PFU Recovered <1
Filtration Efficiency 99.99998%

v     Filter layer containing  0.3% CPC (Cetylpyridinium Chloride) as an antiseptic,
intended to prevent build-up of bacteria (not viruses) within the layer,
thus minimizing the possibility of self-infection from inhaled air.
(For Abstract of Research Regarding CPC; published in the Journal of Infection Control)

Cat. # 05345 - Central one-way filter with single-directional valve for exhaled air.
(To prevent infected patients from contaminating their surroundings, a version without the
Single directional valve is available (Cat. # 05346) – inhaled and exhaled air will pass through
the mask filters.)

Contour conforming, Snug Fit (prevents accumulation of Carbon Dioxide within the confines of the mask.)

Held in place by adaptable similar to Velcro^® straps.

Version # 05345 – fitted with single-directional filter & valve is intended for use by professionals
in contact with patients, and for the public.

Version #05346 - without the single-directional valve is intended for infected patients. The
omission of the valve will prevent spread of contamination, as inhaled air will pass through
the mask. Caution: Whilst the middle layer will prevent outward passage of the viruses, it should
be noted that the antiseptic layer opposite the respiratory orifices is not intended to destroy viruses. 
The duration for use of the mask by infected patients should be limited to short periods.
