Description

Disposable face masks are for daily use. Consists of surface layer, middle layer, bottom layer, ear loop and nose clip. These masks help with:

  • Filtration of particulates (see Filter Efficiency)
  • Bacterial filtration efficiency (BFE)
  • Resistance to penetration by synthetic blood
  • Resistance to flame spread
  • Source control to prevent the spread of COVID-19 by blocking droplets exhaled by the wearer

These masks have the following features:

  • 3-layers of physical barriers: Made with three layers of soft non-woven polypropylenes that help prevent the exhalation of respiratory droplets.
  • Easy to Breathe Through: Highly breathable non-woven fabric makes breathing just as easy as if you weren’t wearing a mask.
  • Comfortable Fit: There is an internal wire on the top of the single-use 3-ply face mask to help it fit securely over your nose and to prevent your glasses from fogging up. The elastic ear loops are soft and will stretch around the ear without excessive strain.
  • Skin-Friendly Materials: Made of soft, non-woven fabric that is odorless and developed to avoid skin irritation.
  • Fiberglass and latex free

Additional information

Bacterial Filtration

Bacterial filtration efficiency (BFE)
A. Pre-treatment: Before the test, place the sample in an environment with a temperature of (21±5)°C and a relative humidity of (85±5)%for at least 4h
B. The bacterial aerosol is culture suspension of staphylococcus aureus
C. Flow rate during testing: 28.3L/min
D. The outside of the mask was oriented toward the challenge aerosol
E. The mean particle size of the bacterial aerosol shall be maintained at(30±0.3) μm

Test result 99.4%.
Classification conclusion: level 3.
Differential Pressure

Reference to ASTM F2100-19 &EN 14683-2019 Annex C, test conditions:
Differential Pressure:
A. Pre-treatment: Before the test, place the sample in an environment with a temperature of (21±5)°C and a relative humidity of (85±5)% for at least 4h
B. Flow rate during testing: 8L/min
C. Test areas:2.5cm in diameter, total area 4.9 cm2.

Test Equipment: Constant temperature and humidity chamber, Respirator particle filtration efficiency and airflow resistance tester.
Test Result: 29.1 Pa/cm2

Classification conclusion: level 3.
Face Seal Fit

Loose-fitting.
Filtration

This mask may help prevent droplets from entering but does not offer a reliable level of protection from airborne particulates. It is not considered respiratory protection.
Flame Spread

Reference to ASTM F2100-19&ASTM F1862/F1862M-17, test conditions.
Flame Spread:
A. The distance between the top of the burner and the minimum height of the sample: (20±2) mm
B. The flame height: (40±4) mm
C. The flame temperature above the burner tip (20 ± 2) mm: (800±50) °C.
D. The linear speed of the head mold at the tip of the nose: (60 ± 5) mm/s. Test Equipment: Constant temperature and humidity chamber, mask synthetic blood penetration tester.

Test Equipment: Constant temperature and humidity chamber, Burning chamber.
Test Result: Class 1
Classification conclusion: level 3.
Intended Use

Helps protect others from the wearer’s respiratory emissions. The CDC has recommended face masks for use by the general public as a form of source control in the spread of COVID-2019. The mask covers user’s mouth, nose, and jaw providing a physical barrier.

This mask is not intended for medical use. This is not a surgical mask, and should not be used in a clinical setting where the infection risk level through inhalation exposure is high. It is always recommended to include masks with other protective measures such as hand washing with non-antimicrobial soap and water, and alcohol-based hand rub if soap and water are not available.
Methods Of Use

1. Wash hands before handling the mask
2. Open the mask
3. White side of the mask is inside, blue side is outside, and the nose strip is at the top
4. Place ear loops over the ear
5. Adjust the mask size, to completely cover nose and mouth
6. Adjust nose strip by slightly bending on both sides of the nose
Specification Standard

ASTM F2100-19 – Test results comply with the level 3 requirements of ASTM F2100-19.
Storage

Store in a dry area at room temperature.
Synthetic Blood Resistance

Reference to ASTM F2100-19&ASTM F1862/F1862M-17, test conditions.
Synthetic blood resistance:
A. Pre-treatment: Before the test, place the sample in an environment with a temperature of (21±5)°C and a relative humidity of (85±5)% for at least 4h, and tested within 1 min after being taken out
B. At a distance of 30.5cm from the center of the sample, 2ml of synthetic blood was sprayed horizontally from the needle tube with an inner diameter of 0.84 mm toward the outer side of the mask at a pressure of 120 mmHg
C. Visual inspection of penetration within 10s.

Test Equipment: Constant temperature and humidity chamber, mask synthetic blood penetration tester.
Test Result: While 120mmHg (16.0kPa) pressure, no synthetic blood penetration on the inside of the mask.
Classification conclusion: level 3.
Warning

• Do not share face masks
• Mask are a single-use item. Discard and replace as needed
• Replace immediately if exposed to liquid
