Great masks; great company

I have made several purchases from Well Before. One of them was for some 3M masks that were reported to have counterfeiting issues. I contacted Well Before and they immediately exchanged them for these masks —in box—no questions asked. They even sent me a bunch of extra masks rather than break up the box. I am very happy with masks and very very impressed with Well Before customer service. Top notch.

They do fit tight as some of reviewers note. The elastic is a quarter inch rubber band material. The masks that were replaced had a 1/8 inch cloth elastic band that was 2-3 inches longer. The old ones were more comfortable but these are a tighter fit. They work for my average size head. Might be tight on a big head.

We do everything we can for our dear customers. It is truly rewarding knowing you recognize this. Stay safe!

Great product

Great quality mask. Well Before has not let me down on any mask orders this year for myself and family. The fit is a bit on the smaller side which is why I purchased them. The last batch I purchased fit my husbands face but were too large for me. These work perfect for me.

We thank you on behalf of our team for your great feedback! We appreciate your positive words


The masks are a little small, and the elastic bands are not adjustable, so the fit is too tight, especially for prolonged use.

Many thanks for your review! We hope this will help others while choosing!

N96 mask review

I have a small face but these masks were just too tight. I work for an ophthalmologist 10 hour days. I couldn't wear them more then an hour without getting an extremely sore face. Wish you could send only one mask to try so if the fit isn't good we could try others without added expense and waste of unused masks. Thanks anyway.

Thank you very much for your honest comments. We will send you an email in order to help!

Honest and Trust worthy

I purchased a box of mask from this company. At first I thought since I needed some mask I’ll just take a chance. I was pleasantly surprised. The level of service was first class. The customer service was very responsive and thorough with their explanation. Shipping was was. The mask was were authentic and real. I have since placed another order. I highly recommend doing business with is company.
