Disposable Surgical Medical Face Masks

Personal Protective Equipment Disposable Dental Face Masks



When you order masks from other countries instead of the USA made masks.  Or you take a free one from the Grocery store or Casino. This is what you get. Not a tested Medical Level Face Mask. Not a Clean and Sterile Face Mask. Not a Face Mask that has a Filter in it to keep you safe. Think about that next time you see,"Made in the USA" and Still buy the other brand from another country only because it is a little cheaper.


Choosing the Right Face Mask

When was the last time you were struck in the face by blood or other bodily fluids during surgery? Studies1 show such incidents occur to OR staff, on average, between 45% and 51% of the time, and that’s an excellent reason to be sure you’re wearing a face mask that provides the protection you need.

But with all the options available, knowing how to select the mask that will give you the right level of protection for the task at hand can be confusing.

Fortunately, that process has been made as easy as 1-2-3 with ASTM ratings.

What is ASTM?

ASTM International is a global organization that develops and publishes technical standards for an expansive array of products, materials, systems and services. Today, more than 12,800 ASTM standards are in use around the world, including ASTM F2100-11, the standard for medical face masks since 2012.

Where does the Easy as 1 – 2 – 3 come in?

In developing ASTM F2100-11, the organization tested material used to make medical face masks on five performance metrics. Based on their test scores, ASTM assigns a numerical rating for the barrier performance of the material:

Level 1 - for low risk of fluid exposure
Level 2 - for moderate risk of fluid exposure
Level 3 - for high risk of fluid exposure

So, how will I know how each mask is rated?

Simply look for ASTM Level 1, 2, or 3 on the face mask package. However, not all face masks are ASTM-rated, so it’s important to check before you choose. It’s worth the effort to find face masks that DO carry the ASTM rating, to be sure you’re getting the proper level of protection.

Tell me more about how masks are tested

The five performance metrics and their related tests are:

Fluid Resistance – Test ASTM F1862
This test evaluates the resistance of a medical face mask to penetration by a small volume (~2 mL) of synthetic blood at a high velocity (80 mmHg, 120 mmHg, or 160 mmHg). The mask either passes or fails based on visual evidence of synthetic blood penetration.
Breathability – Test MIL-M-36954 C: ΔP
This test determines the face mask’s resistance to airflow. A controlled flow of air is driven through the mask, and the pressure before and after is measured. The difference in pressure is divided by the surface (in cm2) of the sample. A lower breathing resistance indicates a better comfort level for the user.
Bacterial Filtration (BFE) – Test ASTM F2101
This test measures the percentage of bacteria larger than 3 microns filtered out by the mask. The challenge material used is Staphylococcus aureus.
Particulate Filtration (PFE) – Test ASTM F2299
This test measures the percentage of particles larger than 1 micron filtered out by the mask. The challenge material used consists of latex aerosol concentrations in a controlled airflow chamber.
Flammability – Test 16 CFR Part 1610: Flame Spread
This test exposes the face mask material to a flame and measures the time required for the flame to proceed up the material a distance of 127 mm (5 inches). Class 1 means the material exhibits normal flammability and is acceptable for use in clothing.


Surgical Face Masks
A surgical mask is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment. Surgical masks are regulated under 21 CFR 878.4040. Surgical masks are not to be shared and may be labeled as surgical, isolation, dental, or medical procedure masks. They may come with or without a face shield. These are often referred to as face masks, although not all face masks are regulated as surgical masks.

Surgical masks are made in different thicknesses and with different ability to protect you from contact with liquids. These properties may also affect how easily you can breathe through the face mask and how well the surgical mask protects you.

If worn properly, a surgical mask is meant to help block large-particle droplets, splashes, sprays, or splatter that may contain germs (viruses and bacteria), keeping it from reaching your mouth and nose. Surgical masks may also help reduce exposure of your saliva and respiratory secretions to others.

While a surgical mask may be effective in blocking splashes and large-particle droplets, a face mask, by design, does not filter or block very small particles in the air that may be transmitted by coughs, sneezes, or certain medical procedures. Surgical masks also do not provide complete protection from germs and other contaminants because of the loose fit between the surface of the face mask and your face.

Surgical masks are not intended to be used more than once. If your mask is damaged or soiled, or if breathing through the mask becomes difficult, you should remove the face mask, discard it safely, and replace it with a new one. To safely discard your mask, place it in a plastic bag and put it in the trash. Wash your hands after handling the used mask.


WHO Says Vaccinated People Should Continue Wearing Masks — Here’s Why.

As the delta variant of COVID-19 quickly becomes the most dominant strain of the virus around the world, the World Health Organization announced on Friday that even people who have been fully vaccinated should continue to follow coronavirus-specific safety measures, including wearing medical face masks and social distancing when around others.

 This announcement comes after several other health organizations and government officials have suggested that masks — both outdoors and indoors — are no longer needed for people who are fully vaccinated in the U.S. And this has led to confusion.

Last month, in a guideline memo called “When You’ve Been Fully Vaccinated,” the Centers for Disease Control and Prevention announced that vaccinated people “can resume activities that you did prior to the pandemic.” This included participating in “activities without wearing a mask or physically distancing, except where required by federal, state, local, tribal, or territorial laws, rules, and regulations, including local business and workplace guidance.”

According to the CDC, those who are fully vaccinated also “do not need to get tested before or after travel or self-quarantine after travel” within the United States and “do not need to stay away from others or get tested unless you have symptoms.”

So, why did WHO shift their position? During a news briefing on Friday, Mariangela Simao, MD, the WHO assistant director-general for access to medicines and health products, stated that “community transmission” of the coronavirus continues to be the reason why safety guidelines are still needed, even for people who are fully vaccinated. And this is, according to WHO, an even greater concern with the delta strain.
“Vaccine alone won’t stop community transmission,” she said. “People need to continue to use masks consistently, be in ventilated spaces, hand hygiene … the physical distance, avoid crowding. This still continues to be extremely important, even if you’re vaccinated when you have a community transmission ongoing.”

“People cannot feel safe just because they had the two doses. They still need to protect themselves,” Dr. Simao noted.

The rapid rise of the delta variant in the U.S., the United Kingdom, India, China, and other countries have already prompted the reintroduction of lockdowns and curfews in places like Australia, South Africa, and Thailand. A two-week lockdown in Sydney began on Saturday — specifically because of an outbreak of the delta variant. South Africa also enacted a two-week curfew and halted travel to and from countries with high COVID cases, as well as indoor dining and the sale of alcohol, due to the delta variant.

Governments around the world are doing what they can to curb the spread of the variant, but the discovery of this strain is very recent, and as a result, experts are still learning about it, what it means, and how people can best stay safe. While it’s been previously stated by Britain’s health minister that people who are fully vaccinated are mostly protected from the delta variant, new findings showed that half of the adults in Israel infected with the delta variant had already been vaccinated.

According to Professor Ran Balicer, MD, PhD, a leader on Israel’s COVID-19 expert advisory panel and chief innovation officer for health service organization Clalit, vaccinations are never 100% effective, and “breakthrough cases” remain likely — especially when it comes to the delta variant. While it’s not reported whether or not the adults in Israel who contracted the delta variant were asymptomatic, Dr. Balicer reported that they did not have severe cases, and the country’s current COVID death rate remains near zero, thanks to mass vaccinations.

Due to the delta variant still being a newer threat, there is no exact data detailing the risk that vaccinated people currently face. WHO officials also confirmed Friday that the delta variant is the most widely spread strain of the coronavirus thus far and, because of that, vaccinations and taking COVID-specific safety measures are the world’s best chance to protect themselves against it, CNBC reports. WHO also warned that the virus is poised to “pick off” those who are most at risk as it continues to spread, including people who haven’t been vaccinated.

As of now, the CDC has not changed their recommendations for vaccinated people in the U.S. Of course, as we know from our experiences in 2020, guidelines could quickly change as more information about the delta variant becomes available. For now, pay attention to the recommendations in your area — and if you’re uncertain, it’s always okay to err on the side of caution and heed your own comfort levels. But one thing’s clear: If you haven’t already, it’s essential to get vaccinated.

“Six hundred thousand-plus Americans have died, and with this delta variant you know there’s going to be others as well. You know it’s going to happen. We’ve got to get young people vaccinated,” President Joe Biden said.
