Which mask is best suited for you?
Medical masks come in different colors, sizes, and performance levels. Which one do you need? Here is our selection guide for medical masks.*
MEDICAL OR NON-MEDICAL
Both can limit droplet transmission, but the higher your level of exposure, the more it is recommended that you choose proven protection. Medical masks are licensed by Health Canada (License from MedSec LEIM / MDEL # 15856). In Quebec, the CNESST recommends the use of a procedural mask when workers cannot respect the distance of 2 meters indoors (1 m outdoors) and there is no physical barrier. That said,Wearing a visor or installing plexiglass cannot replace the mask in places where it is mandatory according to the directives of the Government of Quebec. HCWs working in warm or hot areas should wear a respirator (RPA) type N95 or better.
Most procedural masks are made from a hypoallergenic nonwoven material on the outside and a blown polypropylene membrane on the inside which filters to varying degrees of efficiency (3 ply). MedSec brand masks do not contain graphene.
Masks with a nose bridge that conforms to the contours of the nose provide better protection than those without a nose bridge. It is always at the top of the mask. Some masks have a foam strip which acts as an anti-fog barrier as well.
Procedural masks come with ear loops that are worn around the ears. Some surgical masks come with ties to tie behind the head.
Medical masks come in 4 levels of protection depending on the likely level of droplet and aerosol exposure you will have while performing a task. You may need different masks throughout the day.
|ASTM level 1||Low risk||School, office, patient examinations, operative cleaning, torthodontic work, x-rays.|
|ASTM level 2||Medium risk||Dental treatments, laboratory analysis, dressing changes, emergency room triage.|
|ASTM level 3||High risk||Implant restoration, preparation of crowns, first aid, surgeries.|
|N95 respirator||In contact with infected people||Home care, hospital care, long-term care.|
The ASTM F2100 specification covers the tests and requirements for materials used in the construction of medical face masks used in the delivery of healthcare. All MedSec brand masks are tested in independent laboratories to demonstrate compliance with this standard and come with a certificate of compliance. Follow the instructions for use to maximize the effectiveness of the mask.
|Tests / Standards||ASTM Level 1||ASTM Level 2||ASTM Level 3||N95 respirator|
|Particle filtration efficiency @ 0.1 micron||≥ 95%||≥ 98%||≥ 98%||≥ 99%|
|Bacteria filtration efficiency||≥ 95%||≥ 98%||≥ 98%||≥ 99%|
|Delta P, mm H2O / cm2||<4.0||<5.0||<5.0||<6.0|
|Flammability classification||Class 1||Class 1||Class 1||Class 1|
|Resistance to synthetic blood penetration||80 mmHg||120 mmHg||160 mmHg||160 mmHg|
The KN95 is a mask with an extra layer (4-5 ply), but this mask is not approved by Health Canada. Its bacterial filtration efficiency is ≥ 95%. The CNESST does not recommend that workers replace N95 with KN95, when N95 is required.
The exterior color of the mask is up to personal choice. Blue is the most popular color in the medical field. There are also white, pink and purple. Black is a gender neutral color. The inside color of the mask is always white.
MedSec brand masks are for unisex adults (standard dimensions: 17.5 x 9.5cm). They may also be suitable for some adolescents. Pediatric masks generally come in two categories: those for toddlers (0-4 years old) and those for children (5-12 years old). It is not recommended to give a mask to a child 2 years of age or younger because of the risk of suffocation.
