Face masks are made with 4 layers designed to commercial quality standards for personal protection and breathability. Top and bottom layer - non-woven fabric. 2 middle layers of melt-blown fabric. The face mask is a flat-fold FFR design which is a standard fit for a wider range of face shapes, designed to easily form fit to your face to provide a seal and block airflow from leaking around edges. All masks fit on the face should create a seal forcing your breath through the fabric. Do not touch the front of the mask after use or wash hands immediately. This mask is disposable, if reused the meltblown fabric loses its ability to filter over time. Please discard after use for best performance. Instructions for use: a) Open mask and place over nose on face adjusting the ear loops behind the ears. b) Use adjustable nose clip to form a tight seal to your face by molding the metal strip to the shape of your nose. With one finger on each side of the strip, press and release starting at the bridge of your nose following all the way down. Note, tapping is more effective than sliding your finger to create a tight seal. c) Cover mouth and nose with mask and make sure there are no gaps between your face and mask.Please note the new manufacturer is DongguanArun IndustrialCo.LTD imported by AMP Medical Supply Inc and sold shipped from Toronto.
