You can always count on 3M products and as usual, they are perfect. Thank you 3M for still being the reliable, professional company that you have always been. I appreciate you!
Mask is comfortable and works well but the bands seem intentionally designed to break after a few days off of use as they all break after three-four days of use.

Hello and thank you for taking the time to leave a review. 3M recommends pre-stretching of the 8210 head strap prior to the initial use per the user instructions on the box.
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. Because they’re considered disposable respirators, they’re not designed for significant reuse.
