How effectively do they block particles?

Quite well! But don’t take our word for it—listen to the facts! Our masks block up to 97.1 percent of fine dust particles! Not to mention, each one filters particles down to just one micron. Please note that our masks are not respirators and are not N95-certified.

How much will I have to pay for shipping?

This is one of the most common FAQs about the SHEMA97 mask by The answer? Not a cent, for those who live in the United States and U.S. territories! We include free shipping on every order there and for APO/FPO/DPO addresses. Shipping costs do apply for other countries, like Canada, though.

How do I put on my mask properly?

Wearing your mask correctly maximizes its effectiveness. Check out our instructional video on the process here.

Is every mask reusable?

Yes! Every mask is reusable. Just make sure you wash it frequently.

How many wash cycles will my mask last?

We recommend a maximum of approximately 20 washes. That’s because the filter is deformed slightly with each wash, dropping the particle filtration rate to about 50 percent after 20 washes.

How should I wash my mask?

Please, handwash your SHEMA97 mask by with mild dish soap and warm water. Then, let it air dry.

Can I wear my mask for other reasons besides preventing spread of COVID-19?

Absolutely! The SHEMA97 mask by offers a wide variety of uses. From doing construction work, to bypassing the struggle of allergy season, to mowing the lawn, you can find all kinds of ways to use our masks.

Can I wear the SHEMA97 mask by on planes?

We recommend our v2 styles for air travel usage, as they feature an opaque appearance. Currently, they come in both black and pink! We cannot guarantee individuals working for airlines or the TSA will allow you to wear a non-v2 style, due to their semi-transparent appearance.

How should I determine the size I order?

You may have noticed that we offer four sizes: M, L, XL, and 2XL. M will suit those needing a youth or small adult size. L, on the other hand, should fit medium to large adult sizes. As for XL, it fits extra-large adult sizes. Finally, people with full beards or those looking for extra-large to extra-extra-large adult sizes should order a 2XL.

    My husband and I own a small retail store. We have been selling face shields that we bought in bulk to our customers. My husband and I truly love your masks and wear them in our store. We would love to purchase,say 100 masks if we could get a discount so we could sell them to our customers. Is this possible?

    • says:

      Hi Karen! We are glad to hear you’re enjoying your masks. At this time, we do not have bulk pricing available at that quantity or to resellers, but shipping on all orders is free. Thank you for your interest!

  2. Isabel says:

    Good Evening,
    Approximately 1 week ago I placed an order for 6 SHEMA97 black masks and he only received 5. I will be placing another order for 7 more and would like to know if you all would send the missing mask with this order? Please advise.

    Thanking you in advance.

      Isabel –

      Please reach out to our customer service team via email – [email protected] – regarding this, including your previous order number. The missing mask will be sent to you, either in your new order, or separately. Thank you!

  3. Michael W Boggs says:

    What is the inner/filtering material made out of and how can it be more effective as a KN95 mask when you can actually see thru it?

    • says:

      Michael – our masks are designed to be more breathable than competing mask types, like cloth or paper masks, while remaining as effective. Our masks are not respirators. The nanofiber fabric liner is constructed of PVDF and PES, which are high-performance thermoplastics commonly used in medical applications and water filters.

  4. Rosemary says:

    Ok, my masks should arrive tomorrow, but my question is this. Could you expound on what you mean by ‘wash frequently’ how many uses are used on average before you need to wash?

    • says:

      Hi Rosemary! As the frequency of washing may differ for each customer, we don’t have a recommended washing interval. In general, we recommend washing your mask if you feel that airflow has become reduced, and as often as you feel is appropriate in any circumstance. Thank you for shopping with us!

  5. Rosemary says:

    Thank you so much! That certainly helps!

  6. Kaseyk9 says:

    Can you spray with alcohol between wears?

    • says:

      Hi Kasey! We cannot recommend for or against that – while we do not anticipate that the nanofiber fabric liner of our masks would be damaged by ethanol or isopropyl alcohol (rubbing alcohol), we have not tested that as a sanitization method, and therefore cannot give you any guarantees. Our recommended method for cleaning is to hand-wash with warm water and mild liquid dish soap.

  7. Charity says:


    I’m a third grade teacher and I’m wondering if you’d be willing to donate masks for teachers.

    Thank you,

  8. Debbie says:

    I work in schools and just want to make sure that these masks (which I LOVE, by the way) are safe for use indoors as well as outdoors

    • says:

      Hi Debbie – the SHEMA97 mask by is designed for use indoors as well as outdoors, in any setting where a cloth or disposable non-medical mask might otherwise be used. We have heard from many teachers and other education professionals who use our masks in school settings. We’re glad to hear you’ve been enjoying your masks!

  9. Mark says:

    You’ve mentioned several times here that the Shema97 is not a respirator. Is it therefore inferior to an N-95 or KN-95 in filtering the coronavirus that causes Covid-19? If inferior to an N-95, is it superior to a surgical mask worn by surgeons?

    • says:

      Mark – as our masks are not respirators and are not designed to be used as substitutes for medical grade personal protective equipment, we do not compare them to these standards nor to medical-grade PPE such as surgical masks. The SHEMA97 mask by is designed to be more breathable than competing mask types, like cloth or disposable non-medical masks, while remaining as effective. Like any non-medical mask that is not certified as a respirator, we do not make claims as to the prevention of any infectious disease, including COVID-19, by our masks. The CDC and other authorities advise that the wearing of non-medical, non-respirator masks like ours can help reduce the dispersal of droplets from the mask’s wearer, thereby reducing the potential spread of diseases to others. Thank you!
