Three Layer Face Covering For Extra Protection
- Google Post local.google.com
The recommendation for non-surgical COVID-19 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“.
We have responded to this guideline by introducing a three layer face covering with an inner silk filter layer. This three layer 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 three layer face coverings are constructed of two layers of beautiful high quality quilters cotton, with an inner layer of silk. We chose 100% silk organza for the additional layer not only because it is a very effective electrostatic filter, but it is also easy to breathe through. We found that most of the other synthetic filter materials on the market were much less breathable, and therefore more difficult to wear.
