How do I know your products are real?

Our respirators and masks are manufactured and sourced directly from government-certified partner factories located in manufacturing zones throughout China. Additionally, partner factories hold all certificates indicating compliance and test reports for the products distributed. Our N95 meets United States NIOSH 42-CFR-84 and KN95 meets Standard GB2626-2006.

Are your respirators and masks certified?

Why should you purchase from MedShield USA?

Two reasons: Supplier Trust and Consistent Supply. These are the two main focal points we had when developing our partner factories and supply chain network needed to fulfill the demands of millions of people. The respirators and masks we source are from certified factories that have been extensively vetted to confirm authenticity and quality. This process involves due diligence items such as examining certificates, evaluating factory samples, and maintaining a set of control products for quality comparison.

What is the difference between a N95 respirator and a KN95 respirator?

The difference is which market the respirator was made for. The industry considers a N95 respirator to be equivalent to a KN95 respirator as they have nearly identical performance capabilities. Both the N95 and KN95 respirators are equivalent to other international respirator standards, such as Korea 1st Class (Korea), FFP2 (EU), P2 (Australia), and DS (Japan) respirators.

Are your respirators and masks medical-grade?

There’s a lot of confusion over what “medical-grade” and “surgical-grade” mean? What the respirator and mask factories refer to as “Medical” are in fact FDA-cleared respirators and surgical masks. These masks typically have an antimicrobial/antiviral agent for use in a hospital setting. Mainly respirator masks are severely lacking for our hospital workers and healthcare professionals.

At the same time, there are also masks made for industrial and day-to-day use. Our non-medical N95 (NIOSH-approved) and KN95 respirators are tested through the same set of stringent standards that are required of respirators that claim to filter out 95% of non oil-based particles and contaminants. In fact, experts have concluded that the N95 and KN95 respirators are equivalent to international respirators of the same grade: FFP2 (EU), P2 (Australia), Korea 1st Class (Korea), DS (Japan).

How do you have access to respirators and masks in such large quantities?
