If worn properly this is the best surgical mask out there. Unlike most surgical masks, you can tighten it at the bottom. It has a metal band you crimp. This makes for a secure fit around the cheeks, ensuring a great overall fit. It covers the entire face, even large faces. It’s very easy to breathe in. Just wore these on an long international trip. Totally comfortable, and I felt safe. You don’t even realize it’s there.It’s a 4 ply mask with high fluid resistance. Most surgical masks are 3 ply. It’s also 4 panels instead of 3 like most surgical masks.I’ve tried a ton of masks since March 2020. Whether cheap surgical masks, or fancy cloth. This is, by far, my favorite. And it looks very nice! Don’t think twice, try this mask. Be safe out there!Skip next paragraph for more mask info.Get over Made in China. Do you shop at a big box store? 90% of that stuff is made in China. Do you use electronics? China. Your car? Many components, China. The US sent our manufacturing knowledge and equipment in the late 90’s. It’s called the The WTO. Do your research! LOL It’s how the world works. Please, try buying only US products and see how well your home and life functions. And don’t complain about the cost! I wish we had more manufacturing here as well, we don’t. Get over it!Note: My order came from Pro Dental Supply. I suggest choosing them as your seller.My friend is a dentist (how I discovered this mask) He said to only buy from a dental supply company. Whether on Amazon or elsewhere.
