I am a retired ER RN. These N95 masks are as good or better than the standard N95 masks we used in the ER pre CoVid. When inhaling, the mask noticeably contracts indicating a good, tight, seal==> great protection from drawing in unfiltered air possibly laced with virus or harmful bacteria. Back then we used N95 masks for TB and flu patients. These masks feel like they give a better seal than what we used then.
The quality of the elastic straps weigh home the mask on your head has truly fallen off a cliff. The yellow bands break so fast. Unreliable.

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.
It’s quite small for an adult face. The fit was very tight and uncomfortable.

Thank you for leaving a review! Most 3M N95 models are offered in one size only designed to fit most adults. We do have a few small N95 models designed for smaller faces but we don’t offer a specific model for larger faces. All 3M N95 models fit slightly different, even those of the same size. The respirator you purchased does require pre-stretching of the straps which may help with the tightness you are feeling. Please refer to the user instructions on the box for how to pre-stretch them.
