The Merits of a Reusable Mask
All the disposable masks we've been using this past year accumulate in their environmental and financial implications. I've switched to an Israeli developed, long time reusable, anti-viral mask, coated in zinc oxide nano-particles that destroy bacteria, fungi and viruses, manufactured by Sonovia. The Jerusalem Post reviewed it. They ship worldwide. I find it relatively "breathable" for a cloth mask. https://sonoviastore.com/
