The mask should cover both your nose and mouth to be effective. Properly adjusting the mask over your nose and creating a good seal around your face will improve its effectiveness in reducing the transmission of respiratory droplets and particles.To properly adjust a disposable medical mask
with a built-in nose clip or metal strip, follow these steps:
Wash Hands: Before touching the mask or your face, wash your hands thoroughly with soap and water or use hand sanitizer.
Orient the Mask: Identify the top and bottom of the mask. The top usually has a stiff edge, a nose clip, or an indentation to fit the shape of your nose.
Hold the Mask Properly: Hold the mask with the nose clip or metal strip facing upward and the colored side (usually blue or green) facing outward.
Nose Clip Adjustment: Gently press and mold the nose clip around the bridge of your nose with your fingers. This helps to ensure a snug fit and reduce gaps that might allow air to enter or escape from the top of the mask.
Secure the Bottom: Pull the mask down to cover your mouth and chin, making sure it fits securely under your chin.
Earloop or Tie Adjustment: If the mask has earloops, loop them behind your ears to hold the mask in place. If it has ties, tie the upper ties around the back of your head and the lower ties around the base of your neck for a secure fit.
Adjust Fit: Gently press the mask's edges against your face to mold it closely to your skin, ensuring there are no gaps on the sides. Be careful not to touch the front of the mask while adjusting the fit.
Perform a Fit Check: With the mask properly secured, check for any leaks or gaps by breathing gently in and out. If you feel air escaping from the edges, readjust the mask to improve the seal.
Avoid Touching: Once the mask is on, avoid touching it while wearing it. If you need to adjust or touch the mask, use hand sanitizer before and after touching it, and try to touch only the ear loops or ties.
