LIFAair LM991 High Performance Mask 10pc

Great mask it fits perfectly on my face and it’s not too tight .

Ventajas :Son muy higiénicas, la forma de 3D es excelente, puedes hablar bien sin problemas, puedes respirar bien.Desventajas: si tienes una cara o boca muy grande no la uses ya q esta diseñada para niños o personas pequeñas.

Masks arrived in a box, with each mask individually packed in a sealed plastic bag. Straps are adjustable. I am an adult female with a rather large head, and the mask fit my face just fine.

Note that these masks will not fit an average adult male or female human being. They are individually wrapped and appear to be of decent quality, a bit of a gasket around mouth and nose - interesting. There's no indication of any actual KN95 certification, but they do seem to be of better filtration quality than most cloth masks. I have N95 masks and these do not seem to be as robust. The straps are long, but pull through the front so they can be adjusted for a very snug fit.I would not hesitate to buy these for a 5 year old child.... but I paid $80 for masks that will not fit adults, and were not advertised for children.

These are well designed KN95 masks. They were delivered promptly and the seller responsive when contacted. Comfortable enough to wear on a 12 hour shift. Highly recommended.

Very good
