how long to leave facemask on

Regardless of the type of mask, the protective effect is limited and needs to be changed regularly. It is best to change every two to four hours. If used for a long time, the filter efficiency will decrease and the suction resistance will increase because of the big particles being blocked on the mask surface or the ultra-fine particles blocking the gap of the mask filter material.
