Product specifics
What is this product?
Armbrust USA-Made Surgical Masks are adult, single-use, non-sterile surgical masks sold in 50-count boxes. They use three polypropylene layers, including a meltblown electrostatic filter middle layer, plus elastic ear loops and a malleable metal nose wire.
Is this ASTM Level 3?
Yes. This mask conforms to ASTM F2100-19 Level 3. The product facts table lists the Level 3 evidence points buyers usually check first: PFE, BFE, differential pressure, and fluid resistance.
Is this FDA-cleared?
Yes. The surgical mask is FDA-cleared under 510(k) K210101. The K-number is shown in the hero, the specifications table, and the evidence section so the claim can be checked against the documentation.
What is 510(k) K210101?
K210101 is the FDA 510(k) clearance identifier for this surgical mask. If you are buying for a clinic, school, office, or procurement team, use that number when matching the product page to the documentation packet.
How many layers does it have?
Three. The listed construction is PP spunbond outer, meltblown electrostatic filter middle, and PP spunbond inner. That same construction appears in the specifications table so it is visible without opening a PDF.
Is it sterile?
No. This product is provided non-sterile. It is designed as a single-use adult surgical mask, not a sterile procedure mask.
How many masks come in a box?
Each box contains 50 masks. The current Shopify price for that 50-mask box is shown in the buy box and the add-to-cart button.
What is the SKU?
The Shopify SKU is 3PLY-ARMBRUST-SURGICAL-BLUE-BOX-1X50-R. Procurement buyers can use that SKU together with K210101 when checking the product against purchase records.
Is it made in the USA?
Yes. This product is made in Armbrust’s American factory. The manufacturing section links back to the testing and bulk-order paths for buyers who need more documentation.
Fit, comfort, and use
Is this a respirator?
No. This is an earloop surgical mask, not an N95 respirator. If you need a tighter face seal or headbands, compare it with the KN95 mask or the USA-made N95 respirator line.
How should I choose between surgical, KN95, and N95?
Choose this surgical mask when the requirement is an adult, ASTM Level 3, FDA-cleared earloop mask. Choose KN95 for a more structured face shape, and choose N95 when respirator fit and headbands are the buying requirement.
Will the nose wire help with glasses fog?
The malleable metal nose wire helps reduce gaps at the bridge of the nose. If your glasses fog, press the wire more closely around the bridge and cheeks; fog usually means air is escaping upward.
Are ear loops the same as headbands?
No. Earloops go around each ear and are common on surgical masks. Headbands wrap behind the head and neck, which is why they are common on N95 respirators that need a tighter fit.
Does it fit adults only?
Yes. This product is for adult use. If you need masks for children, compare the kids mask path in the related products section.
Can I wear it for a full workday?
Many exported reviews mention daily work use, comfort, and breathability. Replace the mask when it becomes soiled, damp, damaged, or hard to breathe through. For longer mask-wear guidance, see the Armbrust mask-wear guide.
Can I reuse it?
Surgical masks are designed for single use. For practical disposal and reuse questions, see Can you reuse a face mask?.
How long does it last in storage?
Mask media and elastic can degrade over time, especially with heat, moisture, and sunlight. Store boxes in a cool, dry place and read the expiration guide for more detail.
Can this help with dust or allergens?
Surgical masks can filter many airborne particles such as dust and pollen, but they do not fit like respirators. For dusty or high-particulate work, compare the answer with the dust guide and consider N95 if seal matters.
Is this the right choice for mold or smoke?
For heavy mold, wildfire smoke, or serious airborne particulate, choose a tighter-fitting KN95 or N95 instead of a loose-fit surgical mask. See the mold guide and smoke guide for more context.
Reviews and customer photos
How many reviews are included on this page?
The review module is based on 12,727 exported customer reviews from a source set of 13,848 reviews. The first cards are curated, and the topic filters load matching reviews from the exported set.
What do customers say most often?
The generated summary is based on the exported review set. Common themes include made-in-USA quality, comfort, fit, breathability, repeat purchasing, the nose wire, and use at work, school, travel, and errands.
Do the Comfort and Breathability chips filter reviews?
Yes. Choosing a topic chip now replaces the visible review cards with 10 matching reviews from the exported set, then the show-more button continues through that filtered set.
Are the customer photos clickable?
Yes. Customer photos open in the gallery modal, and the full photo set is loaded from the exported review asset the first time you open the full gallery.
Testing, data, and credibility
Are lab results available?
Yes. The evidence section links the FDA 510(k) letter, ASTM-related reports, and the Armbrust mask-testing database. The most important values are also visible in the product facts table.
What are the PFE, BFE, and breathability values?
The product facts table lists 99.48% average PFE, 99.4% average BFE, 4.7 mm H2O average differential pressure, and fluid resistance pass at 160 mmHg.
Is the mask-testing database an official certification?
No. The mask-testing database is internal, educational testing based on specific samples and dates. It is useful context, but it is separate from the FDA 510(k) clearance and ASTM Level 3 conformance.
What documents should an organization check?
Check the FDA 510(k) K210101 documentation, ASTM Level 3 support, product SKU, country of origin, and published lab values. For purchasing help and documentation packets, use the bulk order page.
