Review on 🚴 EKUTNHR New Upgraded Version: Sports Cycling Filter Cover with Activated Carbon - 2pcs for Men Women – Running Cycling Respirator by Josh Long

Like almost everything, this is a compromise, but a good one. It is very breathable, however this means that filtration and sealing are at a lower level of efficiency. It looks like these are the filters that runners use in polluted air, not the N95 level. They are PM 2.5 which means they filter 2.5 microns. You can read about the effectiveness against the Covid virus on the Internet. Ultimately, I could understand that there is not enough research on the effectiveness of Covid, but that is normal in a general disguise. There is also an article from USA Today explaining that the virus is less than 0.3 microns in size but does not spread by itself. It adheres to particles typically larger than 0.3 microns. The cap is large because there is some space between the nose and the mask. The print is pretty good, but your results will vary. The nose clip more or less prevents the goggles from fogging up, but again, results vary. The material is a heavy nylon mesh and unlike neoprene masks it does not stretch.
