Letusto Airpurity Hyper Purifying Breathing KF-99 Slim Fit Mask, Copper coating, Light Weight, Easy Breathable [Made In Korea, 10pcs]

My gym has been required to wear a mask and it was very uncomfortable to do so, especially when your heart rate goes up during workouts. I tried approx 10-15 different masks without success. This one is just perfect, easy to breathe, thin enough and don’t make your face sweat. One more thing I wanted to ad, is that it’s actually filtering well enough. I did test it in and out by using UV light while introducing bacterial simple. I already bought it 3 times and will keep purchasing as long as it will be available.

Comfortable mask, but that scent! Floral, reminds me of home bathroom spray. Might be helpful if you have to do work in something that smells bad, but I didn't like that about it. The good news is, the scent came out after a gentle soak in a mild vinegar solution, then air dry.

Best Mask I have tried, if you live near a coal plant, buy these

Very comfortable, excellent fit. One of the best masks out there!

This mask is overpriced: smells chemical; too big, covering my face ear-to-ear; not soft on my skin. The worst OF ALL: they say NO RETURN

Highly recommend.

The material on the inside feels like paper and feels weird against the skin on my face. Was excited about these because of the claims of being light weight and comfortable on the skin, but I can't wear them. Just too papery feeling.

Great mask
