Mask Filter Liners
These mask liners are made from an electrostatic charged spunlaced viscose nonwoven material. A mask liner provides an extra barrier between the user and their mask.
Simply put the disposable face mask liner on the inside of your face mask and replace every 3-4 hours of use. These are suitable for professional protective mask, disposable medical mask, and ordinary civilian mask.
Please be sure to wash your hands before handling these filters as they cannot be cleaned or reused.
