(Adult) Zerobay 4-Layers Premium Protective KF94 Certified Face Safety Mask (Individually packed) [WHITE] (Made in Korea)

I've placed 5 or 6 orders of this mask. It provides the best coverage of any mask I've tried. For my face, there are no gaps. The material is comfortable, no scratching. Excellent quality.

Highly recommend these masks! Comfortable and about as effective as you can get outside of the N95 mask. We’ve been using them for over a year and have had no problems (or infection).

Gan máscara que protege muy bien y se ve hermosa y es ligera. Cumple perfectamente con mis expectativas y es equivalente a un N95 americano o KN95 chino. Gran calidad coreana.

I have tried so many masks. I am vaccinated but work among many who are not, and want to make sure I am protected. This seals like a high quality kn95, at least on my face, and is certified in South Korea to filter like the n95. Yet it is breathable...I can wear it all day. I'd rather not wear a mask but since I feel that I should, this is a real find. You can tighten it by putting a little loop in the soft ear elastics.

These are the only masks that fit my face well. They're comfortable and easy to breathe through.
