Bests & Worsts Reviews from Amazon

This product was made from BYD, a Chinese manufacture giant in vehicle, rail transit, battery, electronics and now mask field. Currently, we can find 2 types of disposable masks from China, they are distinguishable from executive standards: GB/T32610-2016 and YY/T 0969-2013. The former one is called "every day mask", usually protects you from dust and pollen; the latter one is called "single use medical mask", designed for non-surgical use in hospitals and clinics, can filter 95% of bacteria. NEITHER MASK CAN PROTECT YOU FROM COVID-19. (Any types of masks or face cover other than N95/KN95 cannot filter coronavirus, but they can block some droplets-the most common carrier of coronavirus, so wearing any type of face cover would significantly reduce your risk to catch COVID-19) A medical mask like this one may be better than every day mask. Though it is called "medical", frontline health workers cannot use this product at work, so don't worry about stealing supplies from them unless they told you so (situation may change). For your next time purchase, make sure to check executive standard.
