ASTM Level 3 is the FDA’s top-rated medical and surgical mask for the face. Intelligent fabric of these masks created by the researchers. The Level 3 surgical mask has an adjustable nosepiece made of non-latex and metal loops that allow for a comfortable fit and more comfort. The most extensive study on covers, yet it reveals their importance in combating COVID-19. The study also shows the advantages of using a suitable surgical mask.
Levels 1 and 3 Masks
Masks are classified as 1 and level 3 surgical masks according to their defense against barriers, at the lowest, Level 1 that offers the highest level of protection and is more secure. However, level 1 masks have more breathability but are not as fast, while Level 3 masks provide more protection but have less breathability. In this article, we will discuss all about level 3 surgical mask:
Level 3 Surgical masks Performance Requirements
The five performance indicators and their associated tests are:
- Fluid Resistance– Test ASTM F1862
This test measures a medical facial mask’s ability to be penetrated by small quantities (~2 milliliters) from synthetic blood with a high speed (80 mmHg 120 mmHg or 160 millimeters).
- BreathabilityTest MIL-M-36954: D:
The test is planned to regulate the face mask’s confrontation to airflow. The airflow is controlled and pushed through the show then the pressure before and after is recorded. Pressure differences are then divided by the area (in cubic centimeters) of the test sample. A lower level of breathing resistance is an improved level of comfort for the person using it.
- Bacterial filtering(BFE) Test ASTM F2101
This test determines the proportion of bacteria greater than 3 microns that are filtered through the mask. The test material can be described as Staphylococcus aureus.
- Particulate Filtration(PFE) Test ASTM F2299
This test determines the percentage of particles that are larger than one micron removed using the mask. The test material is made up of aerosols containing latex within a controlled airflow chamber.
- FlammabilityTest 16 CFR Part 1610 Spread of Spread of Flame Spread
The test exposes the face mask to a fire and then determines the amount of time it takes for the fire to move through the front at a distance of 127 millimeters (5 inches). Class 1 indicates that the material has normal flammability and is suitable for use in clothes.
The FDA is responsible for ensuring the safety and security requirements for all imported substances and ensuring that alternatives PPE products are available in the event of an emergency.
For testing the resistance to the masking fluid
Fluid Resistance: The resistance of fluids indicates the capacity that the surgeon’s mask has to decrease the amount of fluid that could move from the outer layer inside the show through an incident or splash. ASTM demands testing using synthetic blood at pressures of either 80,120- or 160-millimeters Hg to measure moderate, high, or low resistance to fluids.
These pressures result from the capacity to form an air barrier characterized by various tensions.
(Level 1.) (Level 1) (Level 1): 80mmHg is the pressure in the vein system
(Level 2), 120 mm Hg = arterial pressure
(Level 3) 160 mm Hg = high-pressure irrigation
(Level (3) is linked to the high pressures that are experienced when undergoing trauma or procedures that involve (Level 3) are associated with trauma or processes that involve high-pressure irrigation, such as orthopedic procedures.
Face Masks in Canada?
Canadian guidelines state that masks for face in Canada composed from cloth that can be reused are made of at least two layers of fabric that are tightly woven like cotton or linen.

What is a Level 3 mask in Canada?
This Canadian Shield disposable range of masks is manufactured from Canada 100. It’s Level 3 masks have the fourth layer of skin, which provides additional water resistance. Shows that we employ to make disposables are made of 100% polypropylene. That means that they aren’t made from latex or fiberglass.
The most recent advice given by the Public Health Agency of Canada is to wear masks for your face manufactured in Canada comprising two layers of material like linen or cotton (which must be washed with heated water before drying using air after each use.) However, the World Health Organization now recommends masks constructed from three layers of fabric.
Level 3 face mask Canada
The FDA approved this product as a surgical mask in the EUA to be used in health care environments with HCP for use as PPE to create an effective barrier to particles and fluids to avoid HCP exposure to large particles during mask shortages as a result of an outbreak of COVID-19.
Level 3 Surgery Face Mask with Ear Loops
Level 3 Surgical Mask Level 3 Surgical Mask is an all-purpose face mask design used in healthcare settings where patients are at risk of blood or liquid splash. This mask was designed to prevent the flow of blood or body fluids through the layers.
What’s the Level 3 Disposable Mask?
We offer ASTM 2100 Level 3 Certified Medical Masks constructed with three layers of spun-bond pleated fabric, more ear-lobes, and a double nose bridge wire to ensure more comfort, better fit, and safety.
Most Effective surgical mask
If you’re in the vicinity of smoke or interacting with a TB-infected person, be sure to protect yourself by wearing an air-tight mask (N95 Respirator. Then level 3 masks are best for you.
If someone complains that level 3 surgical masks could be harmful to their ears, Or notice indentations on their faces. Souliere says the mask could have been too tight if the cover has adjustable ear loops that are adjustable by stretching them a little to increase the comfort. If they are still too close, you’ll need to make the change to the size.
