Question 1

The straps slide down my hair. Do these come with ear straps?

Accepted Answer

There are no N95 masks that have ear loops, as those are NOT sufficient to provide a complete air-tight seal between the mask and your face. There are, however, KN95 masks that have ear loops, but their ability to maintain air-tight seal is highly questionable. The other answer mentions that there are masks that have ear loops that are used in hospitals, but those are NOT N95 masks. Those are instead surgical masks that are used for different purposes within the medical settings. There is a medical-grade N95 mask called Aura 1870+ that is also made by 3M, but it also has head straps, not ear loops. Also, ignore the answers that tell you to go to a different web site to buy masks because they most likely are trying to sell counterfeit or lesser-quality masks. Genuine N95 masks made by reputable companies like 3M and Honeywell have head straps, as they are meant to provide air-tight seals when worn on your face. Think about it. What good is the N95 designation if the mask does not have air-tight seal? Without the air-tight seal, that designation is meaningless.

Question 2

The box which I received seems genuine but was expired in May 2021. Is all inventory available here clearance of expired stock?

Accepted Answer

Our box says the same. "Use by" date is May 2021 so seems like they have expired. I checked on 3M website, and it validates that the masks are expired.

Question 3

For Manufacturer: Are these/all 3m masks made in a sterile environment from beginning to end (of the manufacturing & packaging process)?

Accepted Answer

No, the masks are not sterile. They are manufactured in a clean environment under stringent quality standards.  Thank you for considering 3M products.

Question 4

how many layers?

Accepted Answer

Hello, The mask is made of a matrixed design, not layers.  It is a N95 respirator that filters at the micron level.  Please contact the 3M Techline at 800-243-4630, option 1 with any questions.  Thank you.
