Lab Tested KN95 Face Masks | 99% Filtration

Lab Tested KN95 Face Masks

Don't just take our word for it — our KN95 masks are independently lab-tested to deliver ≥99% filtration efficiency. When you need verified protection, third-party testing is the gold standard. Every mask we sell has been put through rigorous testing so you can buy with confidence.

What Lab Testing Means for You

  • ≥99% filtration efficiency — independently verified, not self-reported
  • Consistent quality — every batch meets the same high standard
  • Trusted by Fortune 500 companies and healthcare organizations nationwide
  • Transparent results — we stand behind our testing data

6 Sizes for a Proper Seal

Lab-tested filtration only works when your mask fits correctly. A gap at the nose or cheek bypasses the filter entirely. That's why we offer 6 sizes — XL, Large, Medium, Small, XS, and Kids — so you get both certified filtration and a proper fit. Use our mask fit guide to find your size.

Available in White & Black

Our lab-tested KN95 masks come in classic white and professional black. Browse our Black KN95 Face Masks collection or shop all sizes in our KN95 Masks in 6 Sizes collection.
