At present, wearing masks is considered to be one of the most effective means to prevent the spread of new coronavirus. However, there are many kinds of masks sold on the market. What are the differences between them? How to choose correctly? What are the matters needing attention in the use? Let's get together and find out.
N95 and other masks can effectively prevent the new coronavirus. If it is a medical staff or people who often enter or leave the high-risk area, they need to wear medical masks. If it is daily protection, industrial respirator and particle respirator has higher protection level. The protective level of disposable respirator is slightly lower.
N95 is the US standard and KN95 is the Chinese standard. "N" represents non oil particulate matter. "95" represents a minimum protection level of 95%. N95 and KN95 can provide better protection in daily life.
Respirator mask: two way protection, whether inhaled or exhaled must be filtered through mask.
There is a one-way respirator mask: wearers can only protect themselves, unable to protect the environment. It is recommended that you wear a respirator mask.
Mask above N95 level can be used for 1 to 2 days. Disposable N95 respirator can not be reused after being removed.
The disposable surgical respirator will last for 4 hours and should be replaced immediately after wetting.
