A third layer of polypropylene filter fabric is added to a mask - as per the Government of Canada recommendations. This filter layer is sewn in. Your mask will still be washable and reusable and if laundered properly, should not shorten the life span of your mask. It is recommended that you hand wash and lay flat to dry or, wash on a delicate cycle and lay flat to dry. This will be arriving November 10, so any masks ordered previous, are a preorder and will ship as soon as possible.If you are ordering multiple masks, and would like all of them to have this layer, please purchase the same quantity of filter layer.
