[1]. They undergo extensive testing by
trusted third-party laboratories and are assigned a Level 3 rating, indicating their ability to meet stringent requirements for medical use
Key Features
Level 3 surgical masks are designed to filter out microscopic particulate matter, including viruses such as the novel coronavirus
[2]. They must pass
synthetic blood and fluid penetration testing, ensuring their effectiveness in preventing the transmission of bodily fluids
[2]. Additionally, Level 3 masks are
required to be FDA-listed for medical use, meeting strict regulatory standards
ASTM F2100 Standard
The American Society for Testing and Materials (ASTM) has established a set of performance criteria for surgical masks, known as the ASTM F2100
standard. This standard evaluates masks based on several key factors
1. Bacterial Filtration Efficiency (BFE): Measures the mask’s ability to filter out bacteria larger than 3 microns. Level 3 masks must achieve a BFE of
≥ 98% [3].
2. Particulate Filtration Efficiency (PFE): Tests the mask’s ability to filter out particles larger than 0.1 microns. Level 3 masks must achieve a PFE of
≥ 98% at 0.1 micron
3. Fluid Resistance: Evaluates the mask’s resistance to the penetration of synthetic blood at high velocity. Level 3 masks must withstand a pressure of
160 mmHg
4. Breathability: Measures the resistance of the mask to controlled airflow, ensuring comfort for the user. Level 3 masks must have a breathability
rating of < 5 mm H2O [3].
5. Flammability: Tests the mask’s resistance to flame propagation, with Level 3 masks required to meet Class 1 flammability standards
By meeting these stringent ASTM F2100 criteria, Level 3 surgical masks offer superior protection against airborne particles, fluids, and other potential
contaminants, making them an essential choice for healthcare professionals and patients alike.
Benefits of Level 3 Surgical Mask. Level 3 surgical masks offer exceptional filtration capabilities, effectively blocking microscopic particles, including viruses such as the novel coronavirus
[1]. These masks undergo rigorous testing to ensure they meet stringent filtration efficiency standards. According to the ASTM F2100 standard, Level 3 masks must achieve a Bacterial Filtration Efficiency (BFE) of ≥ 98% for particles larger than 3 microns and a Particulate Filtration Efficiency (PFE) of ≥
98% at 0.1 micron
This superior filtration performance makes Level 3 surgical masks an essential protective barrier against airborne contaminants in
healthcare settings.
Fluid Resistance
One of the key advantages of Level 3 surgical masks is their ability to resist fluid penetration. These masks are designed to withstand high-velocity
synthetic blood penetration at a pressure of 160 mmHg. This fluid resistance ensures that healthcare professionals and patients are protected from
potential exposure to bodily fluids, reducing the risk of transmitting infectious diseases.
Breathability
While providing superior protection, Level 3 surgical masks also prioritize user comfort by maintaining optimal breathability. According to the ASTM F2100
standard, these masks must have a breathability rating of < 5 mm H2O [3], ensuring minimal resistance to controlled airflow. This feature allows healthcare
professionals to wear Level 3 masks for extended periods without experiencing discomfort or compromising their ability to perform critical tasks.
The combination of superior filtration, fluid resistance, and breathability makes Level 3 surgical masks an exceptional choice for healthcare professionals
and patients alike, offering maximum protection while ensuring comfort and ease of use.

professor of civil and environmental engineering at Virginia Tech, masks labeled as ASTM Level 1, 2, or 3 can filter out at least 95% of particles of all sizes, with Levels 2 and 3 achieving a filtration efficiency of at least 98% [4]. While the difference among ASTM Levels may not be significant for everyday use, where fit is more important, healthcare professionals and individuals in high-risk environments should prioritize Level 3 masks for optimal protection.
How to Properly Wear a Level 3 Surgical Mask
Correct placement
Proper placement of a Level 3 surgical mask is crucial for effective protection. The mask should fit snugly over the nose, mouth, and chin, creating a seal to
prevent the entry of airborne particles
Ensuring a proper seal
To ensure a proper seal, the mask should be adjusted to eliminate any gaps around the edges. The metal nose strip should be firmly pressed against the
bridge of the nose to create a tight fit. Without an adequate seal, air and small particles can leak around the edges of the respirator and into the wearer’s breathing zone. When properly fitted and worn, minimal leakage occurs around the edges of a Level 3 surgical mask when the user inhales,
ensuring that the user’s breathing air is being directed through the filter material.
Duration of use
Level 3 surgical masks are designed for single-use and should not be worn for an extended period. The recommended duration of use is typically 4-8 hours,
depending on the specific manufacturer’s guidelines. Prolonged use or reuse of the mask can compromise its effectiveness and increase the risk of
contamination.
To ensure proper fit and seal, it is recommended to follow these steps:
1. Place the respirator over your nose and under your chin. If the respirator has two straps, place one strap below the ears and one strap above. If you’re wearing a hat, it should go over the straps.
2. If the respirator has a noseclip (a thin metal bar at the top of the device), use your fingertips from both hands to mold the noseclip firmly against your
nose and face. Do not pinch with one handaj .
3. Conduct a user seal check every time you put on the respirator. This should be done before you enter a patient room. Your respirator may have
instructions on how to conduct a user seal check.
4. Facial hair will cause the respirator to leak, so users should be clean-shaven. Some types of facial hair are acceptable as long as the facial hair does
not lie along the sealing area of the respirator.
Identify and replace certain verb phrases with equivalent noun phrases, focusing on verbs that can be expressed as nouns without changing the overall meaning of the sentence.
Specifically, look for phrases like:
“it influences” → “it has an influence on”
“impacts” → “has an impact on”
“revolutionizing” → “causing a revolution in”
These are just examples. There may be other similar verb-to-noun transformations that would be appropriate.
Identify and replace all prepositional phrases starting with ‘for’ (e.g., ‘for reflection,’ ‘for development’) with equivalent infinitive phrases (e.g., ‘to reflect,’
‘to develop’).
Specifically, look for phrases like:
“for consideration” → “to consider”
“for implementation” → “to implement”
“for analysis” → “to analyze”
These are just examples. There may be other similar ‘for’ phrase to infinitive transformations that would be appropriate.
Avoid overused transitional phrases and fancy adjectives. Instead, use conversational connectors and down-to-earth descriptions. If you come across any
typical AI-sounding phrases or words, replace them with more natural alternatives. These examples may provide you some insights on how to replace these
