MASK INTERFACING GUIDE FOR FILTERS

[Suzanka]

Use medium weight non-woven interfacing for masks. This acts like a safe filter. Please label each mask with a permanent fabric pen and write "WASHABLE FILTER INSIDE". If they aren't labeled  then no one will know about your filter. DON'T USE PAPER FILTERS like coffee filter because they are not washable. The masks are sterilized and washed for the life of the use of them. Thanks!

Good idea, Suzanka.  Another possibility is making masks with a slot for inserting and removing filters like coffee filters.  See Leah Day's mask directions for masks with removable (disposable) filters.

So many ways to make face masks, safety is very important, wear whatever mask you want, but just wear it. People should understand that mask is not only for self safety, but also for people around you. When everyone has a protective mask, the risk of infecting or getting infected is so much lower. Also personal hygiene, using disinfectants. Toilet rolls were the biggest problem for me, but then I started to order them online from clean4less, they have a wide range of products and the prices are lower than the places where I used to buy them before.
