I've read many bad reviews about this company's mask. I have some pros and cons concerning my experience. Cons- I ordered in early 2020 back when pandemic first began and like everything else, it took a while for order to arrive(approx. Mth and a half). Once they arrived, I've been wearing them with no problem. I ordered 8 black mask and an extra supply of PM2.5 filters. The only one issue I've had with one of the mask is the a rubber piece that adjust the ear loop tightness split. Pros- The mask still going strong to this date (2/15/21). I simply let the mask soak in warm before wand washing. (Don't forget to remove the filter before washing). The mask fits my face very snug and I personally feel it protects from coronavirus way better than the surgical mask or cloth mask without filters. I'm only speaking for the black mask I ordered; not sure about other mask this company sells. I'm about to order more since I'm a Postal worker and there's not much air circulation in our building when the A/C or heat isn't blowing. I would recommend the black mask since I've used mine for over a year.
