After looking for masks that looked good and felt comfortable, I finally found the right thing. Only issue: they require a specific filter insert, and the mask-makers didn't sell them. I was so pleased to find what I needed here and at a great price. These filters are recommended by many mask-makers, and are well-constructed and effective. They arrived as per expectations, and I was allowed to track the progress of the shipment. Perfect!
Great service. Masks are not completely anti-haze, they do not fit right to the bridge if the nose, but serve the purpose.
