3M Respirators

As one of the leading designers and manufacturers of respirators in the world, 3M provides products that address the needs of both workplace, regulated applications and do-it-yourself, non-regulated applications. For workplace uses, employees may be exposed to known concentrations of harmful contaminants for part or all of the workday. In these situations, respirators are intended to help protect the wearer by reducing their exposure to airborne contaminants from a level that may be hazardous to one that is considered safe or acceptable according to government established levels. In addition, home users cannot easily determine exposure levels nor do they have ready access to the type of training medical evaluation and fit testing needed to be in compliance with workplace respirator standards. In these situations, respirators are intended to help keep non-harmful dusts and certain particles out of your nose, mouth and lungs and with some filters help eliminate annoying odors only.

About NIOSH Respirators

This respirator is government approved by the National Institute for Occupational Safety and Health (NIOSH) as an N95 class respirator and is designed for workplace, regulated uses and applications. NIOSH certification means the respirator has passed stringent government performance standards including filtration efficiency testing and provides at least 95% filtration efficiency solid and liquid particles that do not contain oil.

Fitting Instructions

1. Cup the respirator in your hand, with the nose-piece at your fingertips, allowing the headbands to hang freely below your hand.

2. Position the respirator under your chin with the nose-piece up. Pull the top strap over your head resting it high at the top back of your head. Pull the bottom strap over your head and position it around the neck below the ears.

3. Place your fingertips from both hands at the top of the metal nose-piece. Using two hands, the nose area to the shape of your nose by pushing inward while moving your fingertips down both sides of the nose-piece.

To help determine if you have put the respirator on properly, place both hands completely over the respirator and inhale sharply. Be careful not to disturb the position of the respirator. A negative pressure should be felt inside the respirator. If air leaks around nose, readjust the nose-piece as described in step 3 of fitting instructions. If air leaks at the respirator edges, work the straps back along the sides of your head.

Wearing the Respirator

To be most effective, this N95 respirator must be worn at all times while you are exposed to non-harmful dusts and particles. If the respirator becomes difficult to breath through or is damaged, immediately go to a non-contaminated area and replace the respirator. Beards, facial hair or anything else that prevents direct contact between the face and the edge of the respirator will decrease the effectiveness of this respirator. Inspect the respirator prior to each use and if any defect is found, do not use. Also, do not use this respirator for any toxic or harmful substances such as lead and asbestos.

25 customers mention9 positive16 negative

Customers are mixed about the air flow of the respirator. Some mention that they love the vent and the exhaust part. However, other customers say that they can't breathe in the mask, it doesn't filter exhalations, and the exhaled breath goes out the valve without filtering it through.

Seem fine but package was crushed
4 Stars
Seem fine but package was crushed
The masks seem fine but would probably only be comfortable on someone with a small head (I buy kids baseball hats) as it is tight on me and I can’t see being comfortable over many hours. Also the box was crushed when I received it. That being said, they will do the job. I am immuno-compromised and wanted to have these masks for situations when social distancing isn’t possible.
