Liz’N Health Medical Grade Surgical Masks    

Wearing face masks has never been more critical amidst the abundance of misleading information. The patent pending Liz'N Health Surgical Mask 3D offers healthcare professionals and the public the protection they need without compromising comfort and breathability. With ASTM F2100 for high breathability, particulate respirator and 4-layer filtration, the Liz'N Health Mask is designed with Medical Professionals in mind. When you maskup, feel confident knowing Liz'N Health Surgical Masks have been tested & approved by Nelson Labs for 99.53% particulate filtration.

We continue to learn more about the SARS-CoV-2 virus and COVID-19. The United States has experienced five waves of the pandemic since 2020, including three in the past year that were driven by new variants. Masks are effective at helping prevent the spread of COVID-19. Research suggests that they could also help protect against other respiratory viruses, such as those that cause the common cold or flu.

Many Uses

The ASTM Level 3 Mask is suitable for Medical, Dental, and Environmental use. 


ASTM F2100 Medical Procedure Masks feature a proprietary four-layer construction which offers you protection, comfort and breathability. This four-layer structured mask has been tested and complies with FDA standards, as it blocks out small particulate and environmental dust.


Fourth layer is made with high quality non woven materials that is soft and nonabrasive to the skin. 

Activated Carbon

Third layer is 2.5ppm which deflects fluid without sacrificing breathability and blocks out odor.


Second layer is made with high quality meltblown polyropylene that minimizes particle penetration.


 First layer is black which signifies reliability and protection that a Surgical mask provides.

Differences Between ASTM Level 3 (Liz'N Health) and N95

“Inhalation vs. Exhalation”

Before selecting the masks to use in your workplace environment, it's vital to understand the differences between some of the most commonly chosen options, including the ASTM Level 3 and others including N95/KN95/KF94.

  • ASTM Level 3 Mask recently approved by the FDA is now considered a significant contender in the fight against the spread of viruses.
  •  ASTM Level 3 has the highest resistance to the penetration of bodily fluids through the filter significantly reducing risks from bodily fluid penetration.
  • ASTM Level 3 are designed specifically to provide the 95%+ filtration protection along with comfort & breathability for prolonged use.
  • N95/KN95 are a worthy option but do not provide the flexibility and comfort for all day use, are not medically approved, and were originally designed for industrial use approved by National Institute for Occupational Safety/Health.

There has been an abundance of misleading information emulating from all public and private sectors as everyone wrestles with the science behind the transmission of the virus. Simply put, we are learning more every day.

We are now seeing the trend where many hospitals and schools (students, staff, faculty and visitors) are required to wear an ASTM F2100 Level 2 medical grade mask. Slowly they are becoming the standard. Here’s why... The N95 was designed to protect the wearer from the environment (inhalation); the reason anyone who sprays chemicals wears one. A surgical mask on the other hand was designed to protect from the inside out (exhalation), because the surgeon does not want to infect anyone in the operating room. People are confused about inhalation and exhalation. If everyone wears a Surgical mask, they will prevent particulates from spreading (transmission as it’s called in the medical world). From a scientific standpoint, 0.3 micron filtration is how an N95 protects. The virus is considered 0.1 micron. Liz’N Health’s uses a medical grade carbon activated filter that is also 0.1 micron.

The country is moving in the right direction and people are starting to take their health into their own hands. Wearing a surgical mask is important to prevent infecting others around you. Hospitals are requesting you wear a surgical mask and, in many cases, started asking people to remove N95s because it protects you...but not other people. With Liz’N Health Masks, you do not need to double mask (inhalation and exhalation). It’s the best of both worlds! We have N95+ protection inside (inhalation) and Surgical mask protection outside (exhalation), and we are approved by the FDA as a Level 3 surgical mask. Our goal as Doctors it to mitigate transmission and lesson the spread of infection.
