Bests & Worsts Reviews from Amazon

I just received the product last week and actually bothered to read the instructions, which said to "Wash Prior to Wearing", which I have to give them credit for stating. I just want to re-emphasize this important statement, coming from a medical professional. I followed through with these instructions by hand washing with liquid laundry detergent and was actually quite surprised at how cloudy and discolored the water was as I was washing it! I have no clue as to what the ingredients were that were washed out, but I was certainly glad that I had bothered to follow these instructions before wearing! It took a bit to wash until the water used to rinse became clear. I did wear it when out a couple of days ago and have to give it a 5 star rating for the quality of being able to comfortably breathe! I had been used to wearing surgical masks in medical settings and have found that all of the other masks I've worn become frustratingly difficult in the aspect of being able to comfortably breathe, especially during a 2 hour trip to the grocery store! I am confident that the copper will be of additional benefit, based on my medical knowledge of how copper surfaces are known for their antiviral and antibacterial properties. I just wanted to emphasize this important aspect of this product, hope it is helpful! :-)
