DIY face mask:
Bandana or cotton fabric, approximately 20-by-20 inches
Coffee filter (or piece of HEPA vacuum filter)
2 hair ties (or rubber bands or pieces of elastic)
Step-by-step instructions to make a DIY face mask:
Fold the bandana in half.
Fold the coffee filter in half and place in the centre of the folded bandana.
Fold the bottom third of the bandana up, then fold the top third of the bandana down.
Loop one hair tie around each end of the folded fabric. They should sit about 6 inches apart.
Fold each end of the fabric in towards the centre and tuck them into each other.
To put on the mask, loop the hair ties over your ears. Adjust the mask to make sure it covers your nose and mouth completely.
