N95 and K95 masks Explained
Both N95 masks and KN95 masks are made from multiple layers of synthetic material (typically a polypropylene plastic polymer) and are designed to be worn over the mouth and nose. Straps behind your ear help to hold the mask in place. Masks reduces wearer’s exposure to particles including small particle aerosols and large droplets (only non-oil aerosols). Perfect for professional use these masks can be worn on construction sites, work places, in public areas or in areas of pollution and concern. Both ratings require masks to be tested for filtration efficiency at capturing salt particles (NaCl). Both masks are tested at a flow rate of 85 L/minute. However, there are some differences between N95 and KN95, highlighted here.
- N95 masks have slightly stricter requirements for pressure drop while inhaling. That means they’re required to be slightly more breathable than KN95 masks. N95s and KN95s are both rated to capture 95% of particles. N95 masks have slightly stronger breathability standards.
- N95s also have slightly stricter requirements for pressure drop while exhaling, which should help with breathability.
- The filter layers of N95 respirators were 8-fold thicker and had 2-fold higher dipole charge density than that of KN95 respirators.
- N95 Masks Inhalation resistance of ≤ 343 Pa compared to ≤ 350 Pa for KN95.
- N95 Masks exhalation resistance of ≤ 245 Pa compared to ≤ 250 Pa for KN95.
In Australia, surgical or examination masks intended to reduce or prevent the transmission of disease or micro-organisms (such as bacteria or viruses) are medical devices. These products are regulated by the TGA and are required to be included in the ARTG before they can be supplied.
The Therapeutic Goods Administration (TGA) is undertaking a post-market review of face masks included in the Australian Register of Therapeutic Goods (ARTG). The TGA post-market review of face masks will validate if the devices included in the ARTG through the Class I inclusion process meet all the regulatory requirements and perform as intended. The review will be done to meet the requirements of the relevant standards for Exhalation, Inhalation Resistance and Particulate Filtration Efficiency, demonstrated by 3rd party laboratory testing results.

N95 Particulate Respirator offers some of the best respiratory protection when worn correctly over the nose and mouth, protecting against the contraction, or spreading, of illnesses like the flu and other infectious respiratory diseases. This type of face mask has been specifically to include highly effective filtration layers capable of filtering out greater than 95% of airborne particulates. Lab test achieved greater than 98% filtering efficiency. Each Mask is individually packaged for hygiene and fold flat to facilitate portability and storage. Individual wrapping makes it convenient to carry and distribute without contamination.
