M-view Global [Pack of 20] MEDIUM SIZE Protective KF94 Certified Face Mask (White), For Adults and Older Children, Individually Packaged, Made in South Korea

Update: The New York Times ran a report in mid December 2021 detailing that millions of bogus "N95" masks had beeb sold to health facilities and individuals (example: through amazon), but continues to note that the KF94 Korean masks are high quality. I compared a blue "surgical' mask - with its side gaps - to one of these KF94 in doing dusty yard work. The blue one let a mess of silt and dust in, especially at the side gaps. The inside of the mask was a mess.This one seemed to filter out all the dust. The outside was uniformly brown with fine dust, and only a bit waa on the outermost back of the side rectangular cheek panels. Then when I looked in the mirror I saw that the dust had been deposited on my face at those touch-down points of the cheek panels, not breathed in. Fit my medium sized man's face very well, as close a fit, I think, as could be hoped for from an out-of-package mask. Decidedly are air filtering, but not uncomfortably so. I am more aware of the filtering than with a simple blue "surgical" mask. Also, don't seem to acccumulate breath smell, if used repeatedly, as blue ones may. If actual virus blockage is equivalent to the effect of the yardwork dust blockage, an effective product. I am very pleased that my choice passes the NYTimes article scrutiny.

Compared to the American N95 and the Chinese KN95, these KF94 are snug fitting and comfortable with a clever three panel design that comes individually packaged in a flat sealed envelope. The filtration panel is wide and wrap around, with a lightweight nose piece that fits well over the bridge of the nose, effectively preventing the annoying eye glass fogging leaks that are a problem with US and Chinese mask designs. Below the filtration panel the form fitting chin panel provides an effective comfortable seal. Inhaling draws the mask into the face assuring effective filtration. Exhaled breath goes through the filtration panel easily, or with a looser fit, exits at the back edge of the mask, in front of the ears. I find these easy to wear for extended periods without irritating the back of the ears.

These masks work well but the fabric that attaches to your nose has a paper feel. I returned these because I was looking for a a mask with more of a fabric feel where it touches the bridge of the nose. I wear a mask at work every day, so comfort is key. However in general, I do prefer these masks that minimize contact to the actual face to where they seal (and avoid leaving marks all over the face)

They are not as thick as other brands; however, I trust that they are Korean made and they bare the KF94 symbol so i will still use them. These feel more like paper product than brands that I have purchased before and therefore the comfort of wearing it is different as well. I will make due with them since I will wear them mostly outside while walking and not while I am in a group and not social distancing (doctor visit).

cannot easily seal with nose and upper face. And the materials feel not thick as regular N95.definitely NOT good for a glass wearing -- too much fog forming.

This fits nicely and gives room to breathe. Also fits nicely around the nose and glasses don't seem to steam up. Probably for a man or larger person the medium might be small. It fits me perfectly, where some of the other masks seemed too big. I like the idea of made in South Korea where we know they respect quality control.

Like the fit and fitting around the face. This mask is a size medium so it works good for smaller faces and women. Once you get the fit correct with the bending of the nose metal piece. Your glasses actually work pretty well with it concerning not getting foggy. That’s big plus!!!

This mask is the only one so far that I have felt comfortable wearing for longer periods of time. I have a relatively small face and this mask fits me very well and sits snug around the face. The construction with the separate nose piece makes for easier breathing.
