BNX Converting, LLC is based in Houston, Texas, and produces all masks and PPE locally in the United States with an American work force. Our facility is CDC and FDA Registered (Registration #3017489417) and we have obtained our NIOSH N95 certification as well as KN95 GB2626-2019 certification. 

N95 Mask Respirators & KN95 Masks

NIOSH Certified Made in USA N95 Masks & GB2626-2019 KN95 Masks

Disposable respirators are the general industry term for face masks designed to protect the wearer from inhaling hazardous atmospheres, including fumes, vapors, gases, and particulate matter such as dusts and airborne microorganisms. Disposable respirators come in many different styles and sizes, to accommodate all types of face shapes. The differences in respirator design impact the respirator assigned protection factors (i.e., the resulting degree of protection from which kind of hazard). These respirators are designed to be thrown away after use.

In North America, the National Institute for Occupational Safety and Health (NIOSH), under authorization of the Occupational Safety and Health Act of 1970, provides a testing, approval, and certification program assuring respirators used in the workplace meet the standards of 42 CFR Part 84. NIOSH respirators are rated N95, N99 and N100 according to their filtration capability. The N95 is by far the most popular disposable respirator for use in the United States.

In addition to CE, other countries such as China have also developed their own national standards of approval for respiratory protective equipment which has become globally recognized. In China, all disposable respirators must comply with KN95 (GB2626-2019) standards. The KN95 regulatory standard refers to a design that ensures filtration efficiency, tight seal with the face as well as minimum leakage.

Comparison of NIOSH N95 and KN95 Respirators

Filtering facepiece respirators (FFR) are subject to various regulatory standards around the world (see table below) and provide a much higher level of protection with face form fitting and greater pressure drop. To claim compliance with a particular standard as listed below, these respirators must meet or exceed required physical properties and performance characteristics, which can vary according to the regulatory bodies of different countries.
Certification/Class (Standard) N95 (NIOSH-42 CFR84) KN95 (GB2626- 2019)
Filter performance (must be ≥ X% efficient) ≥ 95% ≥ 95%
Test agent NaCl
Flow rate 85 L/min 85 L/min
Total inward leakage (TIL) – tested on human subjects each performing exercises* N/A ≤ 8% leakage (arithmetic mean)
Inhalation resistance – max pressure drop ≤ 343 Pa
Flow rate 85 L/min
Exhalation resistance - max pressure drop ≤ 245 Pa ≤ 250 Pa
Flow rate 85 L/min 85 L/min
Exhalation valve leakage requirement Leak rate ≤ 30 mL/min Depressurization to 0 Pa ≥ 20 sec
Force applied -245 Pa -1180 Pa
CO2 clearance requirement N/A ≤ 1%
*Please note: Respirators may be designed to fit people with facial features common in a specific country or region. For example, KN95 respirators may be designed specifically to fit people with facial features common in China and other countries in Asia. As a result, some individuals with different facial features may not be able to achieve a satisfactory fit. This should be considered when selecting and using a respirator approved to other countries and region’s standards.
