These masks have been designed to be comfortable enough to wear throughout the whole day. They are made of soft materials with stretchy elastic ear loops which effectively hold the mask in place on your face. Wearing a face mask can reduce the risk of harmful particles reaching you. These masks will effectively filter the air to prevent harmful bacteria and particles from infiltrating it. These masks are perfect for wearing in all environments to prevent dust, dirt & germs from getting through. Made from 3 layers of polypropylene non-woven & meltblown-smms fabric for use in infection-control practices to minimize cross-contamination. Along the top edge of the mask is an inbuilt metal wire which can be pinched and moulded to the shape of your nose.
