Frequently Asked Questions

Due to unprecedented demand, your order may be impacted. We are working to ramp up production. 

Here are some frequently asked questions:

Q. Where is my order? When will my order ship?

All items on our website that are not marked "sold-out" ship within 2-3 business days from our warehouse in Brooklyn, New York or from one of our other warehouses in the Tri-state Area

Our website is updated to reflect new product inventory. 


Q. Why does my order shows a tracking number that's already been delivered?

A. If your package shows as "Delivered" to the wrong destination, as well as "Archived", odds are that your package received a recycled tracking number.

USPS recycles tracking numbers. During holidays and increased demand in shipping, those numbers recycle a lot sooner before the system clears them or resets them with new shipping information. We do not have any control over tracking numbers given to us by USPS, so we ask that you are patient and wait for shipping information to reset in their system. If you still don't receive your order, or the tracking number doesn't reset within 7 days, please let us know. 

Q. Why did my order arrived in clear packaging?

A. We have streamlined our shipping process to package masks faster. You may receive clear "bulk" packaging. In times of high demand, we may also run out of retail packaging and will use clear packaging instead.


Q. Is my order counterfeit?

A. If you've ordered directly from USS website, our Amazon store,  our Facebook Store, or USS Google Listing then you have received a legitimate product. Each product we sell should have linked supporting information in PDF format. 

You can look for our N*95 logo, USS logo, or Made in the USA logo—some of our masks may not have M95 or USS logos; Email us at if you have any concerns or questions regarding product integrity.



Q. Are these masks FDA approved?

A. Our 3-ply masks are FDA listed under Emergency Use Authorization, for use by healthcare personnel and the general public. They are also manufactured in an FDA registered facility that meets ISO 9001:2015 standards. Our name-brand masks have more information on each product page. If you have any further questions, please don't hesitate to contact our support team. 


Q. What materials are used?

A. Our 3-ply masks are made with non-woven and spunbond polypropylene and contain no latex. Our filter media is electrostatically charged. You can find information on our website regarding accredited testing on mask product pages, and even more information can be found on popular YouTube channels that have tested our masks!


Q. Are masks reusable?

A. As with any filtration device, masks may lose efficacy as filters get saturated, therefore we don't recommend long-term use of any disposable mask products. 

Q. Are masks certified ASTM Level 3?

A. Our surgical, flat style masks and materials all meet ASTM Level 3 as tested at accredited labs like Nelson Laboratories and Eurofins. 


Q. What is the difference between M95 and N95?

A. N*95 is a standard set fourth by CDC/NIOSH which says (among other things) an N95 mask must:

  • Meet high filtration standard of +95%
  • Have head straps (not ear loops)
  • Must be fit-tested for OSHA compliance

M95 series masks are the brand and model of USS masks. Our masks filter over 99% and use ear loops, so our entire M-series of masks M93i, M95i, M95c, M96i are NOT N95/NIOSH compliant.
