This product met all the standards for an N95 mask that I had researched. The construction, especially the bands, is designed to support long term use. Just be aware that the nose piece is very stiff and may take some getting used to.
The yellow straps were too tight although I am not a fat person. And one strap broke off after only wearing it for less than 7 days. Very disappointed with 3M product.

Thank you for taking time to leave a review. Per the user instructions on the box, pre-stretching of the 8210 head strap is required prior to the initial use. 3M recommends pre-stretching of the 8210 head strap only prior to the initial use. If you make the decision to reuse the same respirator additional pre-stretching is not needed. Depending on the number of reuses, pre-stretching each time could potentially weaken the head strap. Note: Because they’re considered disposable respirators, they’re not designed for significant reuse.
These hard masks were extremely difficult to wear as they don't give at all. They also scratched my chin when I wore them more than once
No, I would not recommend this to a friend.

Thank you for your comments and product feedback. It is very important that your 3M N95 Respirator seals completely to your face. The elastic head bands are necessary in order for the mask to fit securely. If a respirator does not seal well to your face, airborne hazards can enter around the gaps between the faceseal and the face. If you cannot achieve a good seal with your respirator, you should try a different model until you find one that is well sized and seals well to your face. 3M offers other N95 models including the 8200, 8210+ and Aura 9205+. It is very important to always follow the model-specific user instructions for your respirator and to do a user seal check (fit check) before each use. Remember, the better the seal, the more of the air that you breathe goes through the filter.
