3M N95 Assembly instructions

N95 respirators are eective at helping reduce the wearer's exposure to airborne particles
such as dusts and mists, but only if they’re worn correctly. Follow these tips to put on, take
o and wear your 3M respirator.

Respirator On First
Respirators should be put on rst before putting on a hat,
eyewear or earmus. The straps should be directly against
your head.
Pay Attention to Strap Placement
The position of the straps is critical to help create a proper
seal of the respirator to your face. The top strap should be
placed above your ears high on the back of the head, and the
bottom strap should sit below your ears around your neck.
Straps should never be crisscrossed, twisted or looped around
your ears. Both straps need to be worn for a secure t.
Do Not Pinch the Nosepiece
Pinching the nosepiece with one hand can result in a poor t
on the bridge of the nose, potentially allowing contaminated
air to leak in through the gap when you breathe in, and could
cause fogging of eyewear when you breathe out. Instead, use
your ngers from both hands to completely mold the
nosepiece to your face.
Try Dierent Respirators
There are many dierent types of disposable respirators that
have a variety of features, such as more comfort, easier
breathability, adjustable straps, exhalation valves for easier
breathing, and dierent sizes. If you do not nd one very
comfortable or you do not get a good seal with one, try
another model.
Beware of Facial Hair
Facial hair such as a beard can compromise the seal between
your 3M N95 respirator and your face, which may reduce its
eectiveness. Even stubble can have an eect on the
respirator seal. You must be clean shaven when using
respirators. However, facial hair entirely within the respirator
cup (e.g., a small goatee or mustache that doesn’t interfere
with the respirator seal) is OK.
Secure Long Hair
Long, dangling hair can also pose problems with strap t
at the back of the head or with the seal to the face. Hair
should be secured in a ponytail or bun between the upper
and lower straps.
Remember the 3 Ds
If your respirator becomes dirty, damaged or dicult to
breathe through, it should be discarded and replaced. Any
N95 respirator that has come into contact with virus particles
should be carefully removed and appropriately handled
after use.
Be Mindful of Shelf Life
Do not use your respirator past its shelf life, typically 3 to 5
years from date of manufacture. The expiration date can be
found on packaging. Respirators should be stored according to
the storage instructions, including at temperatures no colder
than -4 degrees F (-20 degrees C), no hotter than 86 degrees
F (30 degrees C), and a relative humidity of less than 80%.

Tips to Put It On Properly
Place on Face
To start, cup the respirator in your hand with the nosepiece at your ngertips, allowing
the headband straps to hang freely below your hand. Put the respirator up to your face
with the nosepiece over the bridge of your nose.
Position Straps
While holding the respirator in place, pull the top strap over your head so it rests high
on the back of your head and above your ears. Next, pull the bottom strap over your
head and place it around your neck just below your ears. Untwist the straps.
Form the Nosepiece Correctly
To get a good seal around the nose, you need to mold the nosepiece carefully to help
prevent air leakage. To do this, use two ngers from each hand to mold the nosepiece
to the shape of your nose. Push inwards and down while moving your ngers down
both sides of the nosepiece.
Check the Seal
To perform a User Seal Check on a non-valved respirator, cover the respirator with
both hands and inhale sharply or exhale sharply. Be careful not to disturb the position
of the respirator. No air leaks should be felt between the face and the respirator edges.
If air does leak, readjust the nosepiece, work the straps back along the sides of your
head and repeat the seal check. If you cannot achieve a proper t without air leaks, try
another respirator model.
Take It O Properly
How to Take Respirator O
To remove, cup the respirator in one hand to hold it on your face. With your other
hand, pull bottom strap overhead, then pull top strap overhead and remove respirator.
An alternative way to remove the respirator without touching it is to rst pull the
bottom strap over your head and then pull the top strap over your head.
