What is PFE testing?

The Particle Filtration Efficiency (PFE) test While BFE and VFE tests are designed to find out how well a mask filters biological aerosols, the PFE test measures how well it filters airborne particles such as pollen or dust. This is done by filtering particles about 0.1 micron in size.

What does PFE stand for masks?

Particulate filtration efficiency
Particulate filtration efficiency (PFE) The PFE method is led according to the American society of testing and materials (ASTM) F2299 protocol, and indicates the quality of the procedure/surgical masks; however, it cannot be considered as the indicator of respiratory protection performance (Velavan and Meyer, 2020).

What is a PFE filter?

The Particle Filtration Efficiency (PFE) test evaluates the nonviable particle retention or filtration efficiency of filter media and other filtration devices at sub-micron levels. This test is performed on face masks and all filter material that allows for filtration at one cubic foot per minute (1 cfm) flow.

How do you test particle filtration?

Then we use the cornstarch to test the blue mask.

What is PFE level?

PFE(sub-micron Particulate Filtration Efficiency) represents the percentage of submicron particulates filtered at 0.1 microns. PFE is the measure of the efficiency of the mask in filtering particles passing through it. The size of the particles filtered is critical.

What does BFE and PFE stand for?

The N95 surgical face mask has been recommended by USA experts as the best protection from SARS. The mask has a >99\% BFE (Bacterial Filtration Efficiency). The N95 mask has a Particle Filtration Efficiency (PFE) of >95\% @ 0.3 micron. Masks are intended for use in infection control practices.

What are Level 3 surgical masks?

ASTM Level 3 is the FDA’s highest rating for medical and surgical face masks. This mask features an adjustable metal nose piece and non-latex earloops for easy wearing and added comfort.

What is the micron rating of a surgical mask?

Surgical mask standards have higher requirements for capturing virus-sized (0.1 micron) particles, however they vary by region. Pollution masks (respirators) typically capture >90\% of virus-sized particles.

What is a HEPA rating?

HEPA is a type of pleated mechanical air filter. It is an acronym for “high efficiency particulate air [filter]” (as officially defined by the U.S. Dept. of Energy). Using the worst case particle size results in the worst case efficiency rating (i.e. 99.97\% or better for all particle sizes).

What is the PFE of N95 mask?

The N95 mask has a Particle Filtration Efficiency (PFE) of >95\% @ 0.3 micron. Masks are intended for use in infection control practices. These face masks minimize patient contamination to exhaled microorganisms. Offers a >99\% Bacterial Filtration Efficiency (BFE).

What is the difference between Level 1/2 and 3 face masks?

Level 1 masks are generally considered as a low barrier. They are designed for procedures with a low amount of fluid, blood, aerosol exposure or spray. Lastly, level 3 masks are considered a high barrier. They are ideal for procedures with a moderate or high amount of fluid, blood, aerosols or spray exposure.

What is a Level 1 medical mask?

Level 1 masks are the general standard and are best suited for low-risk, low-fluid environments. Level 2 masks are best suited for moderate levels of fluid exposure. Level 3 masks offer maximum barrier protection and are best suited for environments with high levels of fluid exposure.

What does PFE stand for?

Particle Filtration Efficiency (PFE) The Particle Filtration Efficiency (PFE) test evaluates the nonviable particle retention or filtration efficiency of filter media and other filtration devices at sub-micron levels.

What is face mask particle filtration efficiency (PFE) tester?

Face mask particle filtration efficiency (PFE) tester is test machine to determine the particulate filter penetration and filtration efficiency for respiratory protective devices, face masks and melt blown fabrics. The tester with particle generator can provide sodium chloride particles and paraffin oil particles.

Where can I get a PFE test?

Nelson Labs offers a high level of expertise in PFE testing and is one of the only companies to offer this test. In addition, Nelson Labs can perform all ASTM F2100 testing needed.

What is the difference between PFE and CFM?

This test is done on face masks and on all filter materials that allow 1 cubic meter per minute (CFM) flow to pass. PFE (particle filtration efficiency) measures how well a mask filters submicron particles, viruses and bacteria in anticipation that they will be similarly filtered.
