NSF International Public Health Tip: Choosing a Mask
Public health organization NSF International recommends using the “Three Fs” – Fit, Fiber and Flow – when deciding on a mask to help prevent the spread of COVID-19 and other infectious diseases.
Ann Arbor, MI, Sept. 21, 2020 (GLOBE NEWSWIRE) — NSF International is helping consumers choose the most suitable face mask to help prevent the spread of infectious diseases like COVID-19. Do your part – use the “Three Fs” to choose the best mask for you:
- FIT: Masks should fit snugly and cover your mouth and nose, with no gaps or openings. If you feel air coming in from the sides/top/bottom when you breathe, adjust the fit to close the gaps.
- FIBER: Natural fibers like cotton or wool have rougher threads and are better than paper or synthetics at trapping water droplets that carry disease. Look for masks with at least two layers; some masks have a pocket for an extra layer of fabric, paper towel, or even a coffee filter.
- FLOW: You should be able to breathe comfortably through your mask. If breathing is difficult because the mask is too heavy or for health reasons (asthma, etc.), choose a lighter mask you can wear as long as possible. A lighter mask is better than no mask at all.
