The Saftey Silk Insert with the addition of snaps and a nose bridge for snapping into the Chrysalis Bandana. Get extras so you can wash your insert every night.
A recent study shows that masks made with a combination of tightly woven cotton and natural silk filtered out 80% to 99% of aerosol particles. The cotton mask acts as a mechanical barrier to particles, while the natural silk holds a static charge that serves as an electrostatic barrier. The electrostatic effect sucks in and holds onto the tiniest particles, so they don’t slip through holes in the cotton.

Snap Silk Inserts are two layers of natural silk, designed to fit perfectly inside your Chrysalis Bandana. You won’t even know it’s there because the silk is so breathable and soft. To preserve the electrostatic quality of the silk, wash the Snap Silk Insert in cold water; do not wring. Use a gentle soap without bleach, peroxide, or citrus, since harsh additives can break down the silk fibers. Hang to dry. No need to buy more and more filters – with just two, you can swap them out daily.
