Mask Station Information
Mask Station Information
How it works:
Use the hand sanitizer before taking masks.
Take a brown bag or two to store your mask when it is not in use.
Take an information card to help you remember how to care for your mask.
If you know your mask style and size and it is there, help yourself!
If you have a preferred mask and it is not stocked - email and request them.
Stock from Donate A Mask (sizes kids to large):
Sample packs currently include seven masks with the masks provided from Donate A Mask.
Take a sample pack if you don't know your sizing and then take multiples of the masks that fit best. Masks should fit with a good seal all the way around and be comfortable, not tight. Tighter does not ensure a good seal. Email for more information about booking fit testing.
Stock in other drawers:
This includes the V-Flex (9105, 9105s), the Auras (1870+), and ear loop style masks in S and XS (kids) (Canadamasq CA-N95).
Take one of each of the masks you would like to check the fit on. Keep or dispose of this mask.
Once you have an idea of what fits, take enough stock for a couple weeks of use.
When possible, manufacturer information inserts from each mask type are at the station for on-site review

Surgical Masks vs. N95s
Surgical Masks vs. N95s
All N95s remove particulates from inhaled air and some are also fluid resistant as indicated on the product information sheet (e.g. among the OMB masks, the 3M Aura 1870+ is fluid resistant, the 3M V-Flex 9105 is not).
Surgical masks, also known as procedural or medical masks, are designed to help prevent contamination of the work environment or a sterile field from large particles generated by the wearer/worker (e.g., to prevent the spread of the wearer's spit or mucous). While surgical masks may moderately lower risk of transmission when worn by multiple people, one way masking (individual mask wearing among others that are not) is most effective when using an N95.
