Three Layer Face Covering For Extra Protection
The recommendation for non-surgical face masks is that they are made with a minimum of two layers, to an optimum of three. These layers should be made up of both mechanical filtration and electrostatic filtration. If you wish to see a good technical explainer, here is the link to the ACS Publication “Aerosol Filtration Efficiency of Common Fabrics Used in Respiratory Cloth Masks“.
Silk Filter Face Covering for Extra Protection
We have responded to this medical guideline by introducing a three layer face covering with an inner silk filter. This face covering is available as an option for those who would like extra protection. It has become one of our top selling face coverings.
Our 3 layer face coverings are constructed of two layers of high quality cotton, with a non-removable inner silk filter. We chose 100% silk organza for the additional layer. Silk is not only a very effective electrostatic filter, but it is also moisture repellent and easy to breathe through. Most other synthetic filter materials on the market were much less breathable, and therefore more difficult to wear.
To learn more about mask materials and effectiveness in general, as well as why we chose the materials we did, see our page on why we chose 100% cotton and silk here. And see this link to learn more about the filtration properties of silk.
