Β Level 1 and Level 2 surgical
Medically rated surgical-style masks used in Canada and the United States conform to the ASTM F2100 standard and come in three levels: 1, 2, Comparing level 3 masks
[6]. While there is a small difference in filtration ability between the three levels (95% for level 1 vs 98% for levels 2 and 3), the main difference is their
resistance to blood and other fluids [6]. Level 1 masks offer low barrier protection and are not used for aerosols, sprays, or fluids
[5]. Level 2 masks provide moderate barrier protection and can be used for low to moderate levels of aerosols, sprays, and fluids[5]. masks, offering a range of options to meet different needs. Our masks adhere to the highest standards of quality and safety, ensuring effective protection for both medical professionals and patients. Choose our Level 1 and 2 surgical masks for reliable and trusted respiratory protection. Our Level 1 and 2 surgical masks provide a range of options to meet different needs. With a filtration ability of 95% for level 1 and 98% for levels 2 and 3, they adhere to the highest standards of quality and safety. While level 1 masks offer low barrier protection and are not suitable for aerosols, sprays, or fluids, level 2 masks provide moderate barrier protection, making them suitable for low to moderate levels of aerosols, sprays, and fluids. Choose our masks for reliable and trusted respiratory protection.
N95 respirators
N95 Filtering Facepiece Respirators, commonly referred to as N95s, are regulated by the US National Institute for Occupational Safety and Health
(NIOSH) under NIOSH – 42 CFR 84
[6]. Unlike surgical masks, N95 respirators are designed to achieve a tight facial fit and are evaluated for their ability to
filter out at least 95% of airborne particles, including small particle aerosols [7].
N95 respirators require fit testing to ensure proper sealing against the
user’s face[6].
When properly fitted and donned, minimal leakage occurs around the edges of an N95 respirator when the user inhales [7]. However, studies suggest that
even the smallest gaps can cause N95-type masks to lose a disproportionate amount of filtration compared to more flexible fabric masks [8]. N95
respirators are recommended for high-risk environments where exposure to airborne particles is a concern[9].
Cloth masks
Cloth masks are intended to trap respiratory droplets released when the wearer talks, coughs, or sneezes, acting as a barrier to protect the wearer from
breathing in droplets released by others
[9]. The effectiveness of cloth masks depends on the number of layers and the tightness of the fabric weave, with more layers and tighter weaves providing better protection
[9]. While cloth masks may not offer the same level of protection as medical-grade masks or
respirators, they can still be effective in reducing the spread of respiratory droplets in community settings [6].
It’s important to note that while Level 3 surgical masks offer superior protection compared to lower-level masks, they may not provide the same level of
filtration as N95 respirators, especially when considering fit [8]. The choice between mask types should be based on the specific environment and risk
factors, with proper fit and adherence to usage guidelines being crucial for maximizing protection[8].
Conclusion
Level 3 surgical masks play a crucial role in protecting healthcare professionals and patients in medical settings. These masks offer top-notch filtration,
fluid resistance, and breathability, making them essential for high-risk environments. By meeting strict ASTM F2100 standards, Level 3 masks provide
reliable protection against airborne particles, fluids, and potential contaminants.
When choosing protective gear, it’s key to consider the specific needs of the situation. While Level 3 surgical masks offer excellent protection for many medical scenarios, other options like N95 respirators might be more suitable in certain high-risk cases. Regardless of the mask type, proper fit and correct
usage are vital to ensure maximum protection. By understanding the features and benefits of different mask types, we can make informed decisions to keep
ourselves and others safe in various healthcare and community settings.
FAQs
What qualifies a surgical mask as Level 3?
A Level 3 surgical mask surpasses the criteria required for Level 2 certification and must also pass synthetic blood and fluid penetration tests. Additionally,
these masks must be FDA-listed for medical use to ensure safety and effectiveness.
Is an ASTM Level 3 mask superior to a KN95 mask?
Both ASTM Level 3 masks and KN95 respirators provide high levels of particle filtration; however, ASTM Level 3 masks are designed to filter out up to 98%
of both large and small (3.0 and 0.1 micron) particles. KN95 respirators, which are NIOSH-approved, are required to filter out at least 95% of particles that
are 0.3 microns in diameter. The choice between the two will depend on specific needs and standards required by the user environment.
How effective are ASTM Level 3 masks?
ASTM Level 3 masks are highly effective, filtering out 98% of particles that are 0.1 microns in diameter. This level of filtration offers slightly more
resistance to breathing compared to lower levels. These masks meet the ASTM F2100 standard, ensuring a protection level comparable to masks used in
hospital settings.
What defines a Category 3 surgical mask?
A Category 3 surgical mask, such as the Detmold Medical Level 3 Surgical Face Mask, is intended for single use and designed to protect against significant
blood or fluid splashes. These masks are non-sterile and specifically used in environments where high exposure to bodily fluids is possible.
