• People with chronic respiratory, cardiac, or other medical conditions that make breathing difficult should check with their health care provider before using an N-95 respirator because the N-95 respirator can make it more difficult for the wearer to breathe.
• Replace filter frequently for best results.
• If your respirator is damaged or soiled, or if breathing becomes difficult, you should remove the respirator, discard it properly, and replace it with a new one. To safely discard your N-95 respirator, place it in a plastic bag and put it in the trash. Wash your hands after handling the used respirator.
• N-95 respirators are not designed for children or people with facial hair. Because a proper fit cannot be achieved on children and people with facial hair, the N-95 respirator may not provide full protection.

1. Sanitize your hands and put on your N95 respirator mask.
2. Ensure that your clean N95 mask doesn't have any defects such as tears. Ensure, the filters are clean (replace filters as required)
3. Hold the N-95 respirator face mask in your palm with the mouthpiece at fingertips, while hanging the head straps loosely.
4. Position your reusable N-95 mask below your chin with the mouthpiece up.
5. While holding the N-95 mask in place, pull the top strap behind your head and leave it to rest high on the back of your head.
6. Position the bottom strap around the back of your neck, below your ears.
7. Untwist the straps of your washable N-95 mask.
8. Position both your palms over the respirator to check if it fits your face right.
9. After you put on the mask, don’t forget to sanitize your hands again.

Most N-95 respirators are manufactured for use in construction and other industrial type jobs that expose workers to dust and small particles. They are regulated by the National Personal Protective Technology Laboratory (NPPTL) in the National Institute for Occupational Safety and Health (NIOSH), which is part of the Centers for Disease Control and Prevention (CDC).

However, some N-95 respirators are intended for use in a health care setting. Specifically, single-use, disposable respiratory protective devices used and worn by health care personnel during procedures to protect both the patient and health care personnel from the transfer of microorganisms, body fluids, and particulate material. These surgical N-95 respirators are class II devices regulated by the FDA, under 21 CFR 878.4040, and CDC NIOSH under 42 CFR Part 84.

N-95s respirators regulated under product code MSH are class II medical devices exempt from 510(k) premarket notification, unless:

• The respirator is intended to prevent specific diseases or infections, or
• The respirator is labeled or otherwise represented as filtering surgical smoke or plumes, filtering specific amounts of viruses or bacteria, reducing the amount of and/or killing viruses, bacteria, or fungi, or affecting allergenicity, or
• The respirator contains coating technologies unrelated to filtration (e.g., to reduce and or kill microorganisms).
