_The Unmask is not designed or intended to prevent, mitigate, treat, diagnose or cure any disease or health condition, including COVID-19/Coronavirus. Unmasks are intended for general public use only. They are non-sterile and are not intended for use in any clinical or surgical setting or where exposure to bodily or hazardous fluids may be expected, where the risk of exposure through inhalation is high, or near intense heat or flammable gas. Unmasks are not surgical masks, personal protective equipment, or filtering respirators (such as N95 masks)._
Basically, it seems like a soft, breathable mask.....but they make no claims that they will significantly reduce your chances of catching Covid from someone nearby. That said, if the only goal is to meet masking requirements in public places, then it "works".
