What's The Difference Between KN95 And FFP2 Masks ?

First things first —  KN95 and FFP2 masks all have the equivalent effectiveness against airborne particles. In the US, N95 face masks are the approved healthcare standard by the CDC (Center for Disease Control and Prevention), while KN95 masks are compliant with the Chinese standard. FFP2 masks are certified in Europe and available in the UK, offering equivalent protection to N95 and KN95 face masks. 

Ready for the science behind them? Both N95 and KN95 masks are breathable while still being able to filter out 95 per cent of airborne particles, hence the "95" in their names, and can block particles as small as 0.3 microns in size. While the coronavirus particle itself is 0.1 microns, it will likely be attached to something much larger like a droplet created by talking or coughing, making both types of masks an effective way to help prevent its spread. The masks themselves tend to be made from polypropylene, with ear loops being more common on KN95 masks, and straps being more prevalent on N95 models. 

FFP2 masks on the other hand are made from three layers of synthetic non-woven materials which can be found in different thicknesses, with filtration layers included in between the different layers. As N95 and KN95 masks are certified in the US and China, you'll want to look for an FFP2 mask , check more at : https://img.connexions-tech.com. 

Some are disposable, making them an ideal choice for healthcare workers who want to reduce the chances of transmissible diseases. Others are reusable and can be washed, and are better suited for wearers looking to wear a mask while they're out at supermarkets or retailers.
