While an N95 respirator can block 95% of very small particles — very small being considered 0. 3 microns — there is still a 5% chance harmful particles can penetrate the respirator. N95 respirators are not designed for use by children or by people who have facial hair. Some N95 masks come with an exhalation valve that is designed to reduce condensation build-up inside the mask and allow the wearer to breathe easier. These masks, however, should not be used in a situation where a sterile field is required as the exhalation valve allows unfiltered (and possibly contaminated) air to leave the mask.

In order to ensure proper protection for both you and your patients, these instructions — above all others — must be followed. The Occupational Safety & Health Administration (OSHA) also requires that users are trained how to fit and use N95 respirators.

Once you’ve applied soap to your wet hands, you should rub your hands together to wash them for at least 20 seconds before rinsing them off.

Ear Loops — Some masks have 2 ear loops on either side of the mask. These loops are normally made of an elastic material so they can be stretched. Pick up this type of mask by the loops, put 1 loop around one ear and then put the other loop around your other ear. Ties or Straps — Some masks comes with pieces of fabric that are tied around the back of your head. Most masks with ties come with upper and lower ties or straps. Pick up the mask by the upper ties, place the ties around the back of your head and attach them together with a bow. Bands — Some masks come with 2 elastic bands that are placed over and around the back of your head (as opposed to around your ears). Hold the mask in front of your face, pull the top band over the top of your head and place it around the crown of your head. Then pull the bottom band over the top of your head and place it at the base of your skull.
If you’ve already tied the bottom straps, you may need to re-tie them more tightly to get a snug fit.
Ear Loops — Use your hands to hold the ear loops and remove them from around each ear. Ties/Straps — Use your hands to untie the bottom straps first, then untie the top straps. Remove the mask while holding onto the top ties. Bands — Use your hands to bring the bottom elastic band up and over your head, then use your hands to do the same with the top elastic band. Remove the mask from your face while holding the top elastic band.
In medical settings there is most likely a garbage bin specifically for biohazardous items like used masks and gloves. In a non-medical setting where the mask could be contaminated, place the mask by itself inside a plastic bag. Tie the plastic bag closed and then throw the plastic bag in the garbage bin.
