Filter Paper for Reusable Masks (200-300 inserts per pack)
Bacterial Filtration Efficiency (BFE) 95% melt-blown filter paper suitable for use as insert in our reusable masks. BFE refers to the ability of the filter paper to resist bacterial penetration. Each pack contains 50 large sheets of 17.5 cm x 25 cm of filter paper that you can cut according to the size you need. One pack will yield about 200 pieces of adult mask inserts (approximately 8.5 cm x 12.5 cm each) or 300 kids sized inserts (approximately 8.5 cm x 8 cm each). These filter paper inserts are similar to the middle layer used in disposable masks. Using reusable masks with a filter paper insert will give you and your child better protection.
Maximum of 4 packs of filter paper allowed per person.
