The Borje 50-pack features individually wrapped KN95 masks with a matte black finish and a five-ply construction. These masks are designed to be compact and easy to carry, utilizing a fold-flat style that stays clean in your pocket or a purse. The material is lightweight, which helps keep the mask breathable during low-intensity activities like lab work or art classes.
Regarding the build, the mask uses ultrasonic weld points to attach the ear loops. Experience suggests that these points can be a weakness, with some straps "popping" if they are stretched too far. The nose bridge is a malleable aluminum strip, though it lacks a memory coating and may require re-pinching if you move your face a lot while talking. The sizing for this model tends to run smaller than industrial brands, making it a better fit for those with medium or small facial profiles.
Specifications indicate that the fifth layer is a lightweight non-woven backing. This helps keep the overall weight of the mask down, but it also means the mask might feel a bit softer and can "suck in" slightly if you take a very deep breath. For standard daily use, this is a practical and economical way to keep a large supply of masks on hand.
For a mask with a more rigid structure that prevents it from touching your mouth during heavy inhalation, consider the 3M 8210 cup-style respirator.
