Review on 🔒 Enhanced Black Reusable Earloop Filter Valves: Efficient Ear Protection Solution by John Brouillard

The valve on these masks is thermally soldered into the fabric but did not fit the liner covering the valve making it unusable. And that's the type where the mask covers the chin, which allows the exhaled air to get into the eyes instead of escaping through the valve. Because the valve doesn't work. The mask is so thick that no air can pass through. So he enters the mask from above. There is no way to pull it tight enough, the elastic is too stretched.
