These days, people all over the country are paying attention to masks- "medical masks", "medical nursing masks", "surgical mask", "medical protectivelock the daily cross-contamination between medical staff and patients, and there is no particularly high requirement. If it is used by the public, that is to say,KN95 Face Mask, it is used to block bad breath and pretend, the actual effect of protection is not very ideal.

Generally, the fWhen making masks, enterprises usually divide them into three layers: the internal absorbent layer, the middle filter layer,Full Body Disposable Coverall, and the external waterproof layer. Each layer has a special role (here is the key point, which will be used later). Because of the different workplaces, the particulate matter that people are exposed to can generally be divided into two categories: oily and non-oilard, KN type masks are divided again according to their filtering performance on non-oily particles, so we are familiar with KN90, KN95 and KN100 masks.

If you can choose a mask without a breathing valve, try to choose a mask without a breathing valve. (For the safety of others) If you really don't have a mask,free shipping disposable coverall, stay at home and don't go anywhere!
