Bests & Worsts Reviews from Amazon

Prior to using the masks for the first time, I decided to hand-wash one of the masks in warm water as recommended by the manufacturer. I used a small amount of Ivory soap (hand bar) so as not to expose the mask to any harsh chemicals. When I rinsed the mask, the rinse water was colored pink! The question is, where did this pink coloration come from? The mask does not appear to be composed of any red-colored materials. I'm wondering if this pink-colored rinse water is an indication that the zinc nanoparticle coating has in some way been adversely affected by the simple act of washing in plain soapy water. At this point, I'm not sure how safe it would be to wear these masks. Once dry, I would not want to inhale whatever substance it was that produced the pink coloration. And if the coloration came from the zinc coating being compromised, the masks would likely no longer be effective in neutralizing any potential pathogens. On a side note, the masks did not come with any separate nose-bridge clips, as some have mentioned, nor did the masks come with any pouch(s). *** UPDATE *** It has been almost 3 weeks since I originally submitted this review, yet I have not received any feedback from Sonovia regarding my experience with their mask. Additionally, shortly after submitting this review, I submitted similar feedback on Sonovia's storefront page on Amazon; there was no response to that feedback either. If you look at a couple of the 5-star reviews for this product, you'll notice that Sonovia went out of their way to thank those customers for their purchase and for their positive review. It only took Sonovia a few days from the time the customers submitted their review for Sonovia to express its gratitude! One individual posted on Sonovia's storefront page about how she wanted to return one of the two masks she had purchased. She explained that her husband had refused to wear the mask due its outrageous price. Well, guess what: the company reached out to her and negotiated a price that was acceptable so that she wouldn't have to return the mask. What does all of this suggest? It suggests that this company, Sonovia, is more interested in promoting its products and generating sales than it is at addressing a potential safety and/or performance issue with their product. Bottom Line: Think twice before you buy these masks. If you've already purchased them and it's within Amazon's return period, by all means, return them. If not, just discard them and chalk it up to a very costly learning experience.
