ASTM Level 2: Ideal for procedures in which there is moderate risk of fluid exposure (splashes or sprays can be produced). ASTM Level 3: Ideal for procedures in which there is high risk of fluid exposure (splashes or sprays will be produced).
What are ASTM levels?
In the context of face masks, ASTM levels describe how well a mask performs when tested on bacterial and small particulate filtration ability, fluid resistance, and of course, flammability (a mask on fire is no help at all).
What is level1 mask?
Level 1 masks are generally considered as a low barrier. They are designed for procedures with a low amount of fluid, blood, aerosol exposure or spray. Plus, they are latex or fiberglass free. Examples include impressions, operatory cleaning, patient exams, orthodontic work, as well as lab trimming.

What is ASTM Level 3 certification? – Related Questions
Which is a better mask Level 1 or Level 3?
Level 1 masks are the general standard and are best suited for low-risk, low-fluid environments. Level 2 masks are best suited for moderate levels of fluid exposure. Level 3 masks offer maximum barrier protection and are best suited for environments with high levels of fluid exposure.
What are the safest types of masks?
Loosely woven cloth products provide the least protection, layered finely woven products offer more protection, well-fitting disposable surgical masks and KN95s offer even more protection, and well-fitting NIOSH-approved respirators (including N95s) offer the highest level of protection.
Is a Level 1 mask 3 ply?
Medical Masks Filtration Requirements
ASTM Level 1 requires a minimum 95% filtration rate. The design is often a minimum of a latex free 3 ply material, fitted nose band, and pleated fabric.
How many ply is a Level 1 mask?
3 Ply Disposable Pleated Masks (Level 1) | 50 Pack.
What are Level 3 masks made of?
3 LAYERS OF PROTECTION – Constructed of high-quality ultra-soft breathable non-woven fabrics, each mask provides 3 ply protection: 1) Leak proof liquid barrier protection 2) Filter layer filters airborne particulates and 3) Ultra-soft skin contact layer for comfort.
What is the material of surgical mask?
The typical material used to manufacture surgical face masks are polypropylene either spunbond or melt blown. First layer of spunbond polypropylene has a density of 18 GSM to 25 GSM usually of blue, green, pink or white colour.
Which masks are best for Covid?
An N95 offers the highest level of protection. It offers more protection than a medical mask does because it filters out both large and small particles when the wearer inhales. Non-surgical N95s can be used by the general public.
Are surgical masks as good as KN95?
In fact, N95 and KN95 masks were found to be 48% more effective than surgical or cloth masks, according to a CDC study. Wearing an N95 or KN95 mask reduces the odds of testing positive for SARS-CoV-2 by 83%.
Is KN95 as good as N95?
The difference between the two types of masks is the certi cation. N95 is the United States (U.S.) standard and the KN95 is the China standard. Only N95 masks are approved for healthcare use in the U.S. KN95 masks have many of the same protective properties.
How many times can you wear a KN95?
Rotate and use a different KN95 mask every day so you do not wear the same mask more than once every 72 hours. Note: If following this rotation, KN95 masks may be reused as long as they do not become wet, visibly soiled or deformed, causing them to not fit well anymore.

How do I clean my N95 mask?
Submerging an N95 in 125C/260F degree steam or boiling water for 3 minutes will disinfect the mask without significantly reducing its filtration efficiency (FE). Don’t excessively stir the mask if you boil it, use only enough manipulation to keep it submerged.
How many times can an N95 mask be sanitized and reused?
CDC recommends limiting the number of donnings for an N95 FFR to no more than five per device. It may be possible to don some models of FFRs more than five times [2]. Fit performance during limited reuse should be monitored by the respiratory protection program manager or appropriate safety personnel.
