We are sad for the EXTREME winter weather that you guys endured recently! The bad weather led to delayed delivery, but you kept us well-informed, as our family prayed for Texas! We were thrilled to receive REAL, AUTHENTIC 3M N95 masks from Well Before--especially after receiving a box of "fakes" from a different company! We will order more from YOU, the real deal!
Thank you so much for choosing us! we aim to provide the best PPE for our customers!
Fits very well
We are happy to hear it fits well!
I don't like the around the head bands - very uncomfortable and awkward for me. I would prefer ear loops.
Thanks very much for your review of these masks, we are oping to have earloops N95 masks soon!
With the proliferation of so many counterfeit PPE products, it is important to find a company that you can trust. WellBefore is that company. They carefully screen their products, provide high quality items that are true to their description and offer amazing customer service!
Many thanks for your great review! We sincerely appreciate your words!
I was upset when I examined my order. These masks cannot be used for personal protection against Covid because they have an exhalation valve. I don't know why I ordered them since I know valves should not be used. It makes me doubt whether I was sent what I ordered. The Pro model is also discontinued by 3M and I don't recall that information in the description. You indicate no return on this item so I guess I'm stuck. It would be a service to alert the customer to the uses and limitations of this particular mask.
A great purchase during the pandemic with efficient service!
Love these! Very comfortable with protection
Great review! Thanks for purchasing these!
I was so happy to be able to order the 3M N95 masks. This website does a great job of notifying stock availability, even though it's pricey. I paid more than $80 for 20 N95 masks.
Thank you so much for your review! we aim to provide the best prices possible! stay safe!
