FACE MASKS X 50 ( TYPE R 2 Approved )

What's the difference between Type 2 and Type R 2 Facemasks?

 

Type II medical face masks are recommended as a means of source control, i.e. they decrease the transmission of a virus by preventing the spread of respiratory droplets produced by coughing or sneezing.

Type IIR medical face masks are also splash resistant and are used in clinical settings to protect the wearer against splashes of blood or bodily fluids.

A properly worn 3 ply surgical face mask may help block transmission of large-particles microorganisms from droplets, sprays, splatters and splashes. This mask may also reduce the likelihood of hand to face contact.

 

 

How to put on your facemask.

 

1.Wash your hands for 20 seconds,

or rub your hands together

thoroughly with minimum 70%

alcohol- based hand sanitizer

 

2.Position the colored side of the

mask outward, ensure the nose

band is on the top. Put on the

face mask

 

3.Press to the nose band on

both side of the nose bridge

for a better fit

 

4. Pull the bottom of the mask

over the mouth and chin

 

how to remove your face mask:

 

1.Wash your hands for 20

seconds, or rub your hands

together thoroughly with

minimum 70% alcohol- based

hand sanitizer

 

2.Dispose of the used

mask in a closable bin

Wash your hands for 20

seconds, or rub your hands

together thoroughly with

minimum 70% alcohol- based

hand sanitizer

 

3.Remove the mask by unhooking

both ear loops. Avoid touching

the front of the mask. If you do,

perform the hand hygiene

 

*Avoid touching the mask while using it,

as it might have pathogens on it. if you

do, clean you hands with minimum 70%

alcohol- based hand rub or wash hands

with for 20 seconds soap and water.

 

Bacterial Filtration Efficiency (BFE)

and Differential Pressure (Delta P) Final Report

 

Test Article: LOT: 200319

Product Code: PRO101

Study Number: 1300827-S01

Study Received Date: 18 May 2020

Testing Facility: Nelson Laboratories, LLC

6280 S. Redwood Rd.

Salt Lake City, UT 84123 U.S.A.

Test Procedure(s): Standard Test Protocol (STP) Number: STP0004 Rev 18

Deviation(s): None

 

Summary: The BFE test is performed to determine the filtration efficiency of test articles by comparing

the bacterial control counts upstream of the test article to the bacterial counts downstream. A suspension

of Staphylococcus aureus was aerosolized using a nebulizer and delivered to the test article at a constant

flow rate and fixed air pressure. The challenge delivery was maintained at 1.7 - 3.0 x 103 colony forming

units (CFU) with a mean particle size (MPS) of 3.0 ± 0.3 μm. The aerosols were drawn through a sixstage,

viable particle, Andersen sampler for collection. This test method complies with ASTM F2101-19

and EN 14683:2019, Annex B.

The Delta P test is performed to determine the breathability of test articles by measuring the differential

air pressure on either side of the test article using a manometer, at a constant flow rate. The Delta P test

complies with EN 14683:2019, Annex C and ASTM F2100-19.

All test method acceptance criteria were met. Testing was performed in compliance with US FDA good

manufacturing practice (GMP) regulations 21 CFR Parts 210, 211 and 820.
