IRIS OHYAMA NRN-60PM Safety Pleated Masks ( 60 Pieces Per Box )

 

Premium-Fit Japanese Disposable Masks

 

As global communities spare no effort to contain this CoVID-19 pandemic, the need for higher quality face masks cannot be overstated. IRIS Ohyama Co., Limited of Japan aims to achieve this by providing higher quality materials, functionalities, and workmanship for its face masks to strengthen this effort.

 

JosephSan is proud to introduce this professionally made Face Masks for your daily protection.

 

These face masks are subjected to Particle, Bacterial, and Viral Filtration Efficiency (PFE/BFE/VFE) tests.

 

Tested by KAKEN TEST CENTER of Japan, these product safety approbations were performed on face masks and devices, that are designed to provide protection against biological aerosols.

 

This test is used for FDA 510(k) submissions for surgical masks. And it is also required by ASTM F2100 and EN14683. Passing this test is deemed to comply with ASTM F2101 and EN14683. The Applicable Standards are ASTM F2100, EN 14683, and ASTM F2101.

 

Particle Filtration Efficiency ( PFE )

 

The Particle Filtration Efficiency (PFE) test evaluates the nonviable particle retention or filtration efficiency of these face masks at sub-micron levels. This test is performed on these face masks with a constant flow rate of 28.3 litres per minute (LPM) or 1 cubic foot per minute (CFM) passing through it.

 

Also referred to as Latex Particle Challenge, this test is required for ASTM F2100 and is performed according to the ASTM F2100 and follows the basic principle of ASTM F2299. Kaken Test Center, in Japan, offers a high level of expertise in PFE testing and is one of the leading companies to offer this test and can perform all ASTM F2100 testing needed.

 

In Particle Filtration Efficiency testing, the filtration efficiency of these face masks against sub-micron particles cannot be determined using viable challenge particles. This procedure involves the generation of a particle aerosol using JSR-Size Standard Particles SC-0100-D Spherical Polystyrene Standard Particles with a particle generator. The particles are counted with a laser particle counter.

 

The latex particles used in this procedure have a narrow standard deviation and the design of the particle generator produces a consistent particle challenge. Testing is conducted at a single particle size of 0.1µm (0.100 ± 0.003 µm). ASTM F2100 specifies a challenge particle size of 0.1µm. The particle counter is an optical laser based device and operates at a flow rate of 1 cubic foot per minute (CFM) or 28.3 liters per minute (LPM).

 

The experimental area is 49.0 cm².

 

The Particle Filtration Rate of this face mask is 99.7% .

 

 

Bacterial Filtration Efficiency ( BFE )

 

The Bacterial Filtration Efficiency test determines the filtration efficiency by comparing the bacterial control counts to test article effluent counts. The test is conducted using Staphylococcus aureus subsp. aureus ( ATCC® 6538TM ) as the challenge organism. After the filtration media is preconditioned, a liquid suspension of S. aureus is aerosolized and delivered to the filtration media at a constant flow rate of 28.3 litres per minute (LPM) or 1 cubic foot per minute (CFM).

 

The aerosol droplets are drawn through a six-stage Andersen sampler for collection. The number of bacterial aerosol droplets contacting the filter media is determined by conducting challenge controls without filter medium in the test system. Challenge controls are maintained at 1,700 – 3,000 colony-forming units (CFU) with a mean particle size (MPS) of 3.0 ± 0.3 µm. This allows filtration efficiencies to be reported up to >99.9%.

 

The BFE test offers many advantages over other filtration efficiency tests. It has been used with little or no modification for years and provides a standard reference for comparison of filtration materials. The mean particle size can be tightly controlled and is sized using a six-stage viable-particle Andersen sampler, permitting stage-by-stage analysis. The BFE procedure is reproducible and provides a more severe challenge to most filtration devices than would be expected in normal use. Large numbers of material can be evaluated in a relatively short time.

 

BFE testing is commonly performed along with the Differential Pressure (Delta P) test.

 

The Bacterial Droplet Filtration Rate (BFE) for this face mask ≥ 99.7%.

 

Viral Filtration Efficiency ( VFE )

 

The Viral ( Droplets ) Filtration Efficiency (VFE) test follows the same procedure as BFE, except the challenge organism used is the Escherichia coli bacteriophage Phi X174 (ATCC® 13706­B1™).

 

The test standard applied is ASTM F2101-14.

 

Challenge controls are maintained at 1,100-3,300 plaque-forming units (PFU) with a mean particle size (MPS) of 3.0 ± 0.3 µm. This allows filtration efficiencies to be reported up to ≥ 99.7%.

 

Features

 

As these masks are professionally made and tested, we have the pleasure to present the following features:

 

  • 99% Viral (Droplets) Filtration Efficiency (VFE) – Filtration of Virus Splash (Bacteriophage phiX174) – 3.0µm in diameter or larger
  • 99% Bacteria Filtration Efficiency ( BFE ) – Filtration of Bacteria Splash (Staphylococcus aureus) – 3.0μm in diameter or larger
  • 99% Particle Filtration Efficiency – Pollen and Dust Particles – 0.1µm in diameter or larger
  • This face mask is incredibly soft and comfortable to wear. The edges are very gentle on the skin.
  • Woolly spandex ear-loops are extraordinarily strong, easy to put on and exceptionally soft for the ears.
  • Non-woven materials are waterproof.
  • Pleated adhered-three-layer filter retains its three-dimensional shape. This creates a breathing space between the mask and the face.
  • The special V-cut shape (on the edges) reduces the gap between the face and cheeks.
  • Nose bar is made of safe and flexible polyethylene strip to fit the shape of the nose.
