Mask vs. Respirator
Mask Respirator
Masks help protect the patient and the
environment from the exhaled breath of the
health care worker.
No Minimum filter efficiency standards for
surgical masks.
No NIOSH approval.
Masks are loose fitting and are not designed
to seal against the face.
Respirators are designed to help protect the
health care worker by reducing the exposure
of the wearer to airborne contaminants while
protecting the patient and environment from
exhaled breath
Minimum filter efficiency standards are set by
NIOSH e.g.N95. Most of the inhaled air is
drawn through the filter media and not through
gaps between the respirator and the wearer’s
face
Are NIOSH approved.
Snug fit around the face to create a good
face to respirator seal to help avoid leaks
where contaminants may enter. 3
Definition – N95 Series
The "N" or "P" designator identifies a filter's degree of protection against oil aerosols. N-series
filters are not resistant to oil, while P-series filters are strongly resistant.
Efficiency
Both the N95 and P95 filters are 95 percent efficient in removing fine particles from the air, the
minimum level of filtration approved by the National Institute for Occupational Safety and
Health. Higher efficiency ratings of 99 and 100 exist in both series, though the N95 filter is the
most common.
Warnings
These filters only protect against airborne particles, not chemicals and gases.

United States NIOSH Standards: define the following categories of particulate filters:
Oil resistance Rating Description
Not oil resistant
N95 Filters at least 95% of airborne
particles
N99 Filters at least 99% of airborne
particles
N100 Filters at least 99.97% of airborne
particles
Oil Resistant
R95 Filters at least 95% of airborne
particles
R99* Filters at least 99% of airborne
particles
R100* Filters at least 99.97% of airborne
particles
Oil Proof
P95 Filters at least 95% of airborne
particles
P99 Filters at least 99% of airborne
particles
P100 Filters at least 99.97% of airborne
particles
*No NIOSH approvals are held by this type of disposable particulate respirator. 3
European standard EN 149
Class Filter penetration limit (at 95
L/min air flow) Inward leakage
FFP1 Filters at least 80% of airborne
particles <22%
FFP2 Filters at least 94% of airborne
particles <8%
FFP3 Filters at least 99% of airborne
particles <2%

3M Qualitative Fit Testing
3
3M Qualitive fit tests provide a pass or fail result based upon the wearer tasting a test agent.
They provide a subjective measure of the quality of the seal of the face-piece to the wearer’s face.
These tests are suitable for disposable respirators and half masks.
3M offers two kits:
• 3M FT10 includes a sweet tasting test agent
• 3M FT30 includes a bitter tasting test agent
The choice between the bitter and sweet test kit is a personal one, however a small percentage of
the population are unable to detect saccharin –if you discover this in your workforce, the bitter test
must be used.

During the fit test a series of exercises pictured below are performed involving breathing,
head movements and talking.:

If the entire test is completed without
the wearer tasting or smelling he aerosol –
a fit test pass results.
If the taste/smell of the aerosol is detected
at any point during the test, the test is
terminated and repeated after a break.
