N95 OR KN95? What is the difference?
The distinction between N95 and KN95 masks may be confusing with identical sounding names. What are the masks of KN95 and the masks of N95 are the same? This useful table illustrates the variations between masks N95 and KN95 (and all the features that are identical).
Briefly, N95 masks are US breathing masks, while KN95 masks are Chinese mask standards. Those are criteria which manufacturers need to meet in order to mark their masks as N95s in the United States National Institute of Occupational Safety and Health. The two masks are, given the long list of variations, identical or nearly similar to the features that most people care about.
According to 3M, “It is fair to find” China’s KN95s as the equivalent of US N95s, according to mask manufacturer. Even extremely similar are Europe’s mask standards (FFP2), Australia (P2), Korea (KMOEL) and Japan (DS).
Many consumers are most worried about how many particles the masks contain. These air masks are similar on this scale. The masks are rated 95% (0,3-micron particles, to be exact) of tiny particles.
These masks are classed as capturing 95 per cent of the 0.3 microns, the general expectation is that masks can absorb just 0.3 microns of particulate matter. For instance, in the South China Morning Post here is an infographic claiming that.
