3M 8210 N95 masks dropped to $0.89/each about 5 months ago and haven't budged since then. Presumably they could now ramp up production if required. I often wonder why Amazon doesn't just presume guilty unless proven innocent when it comes to life-safety equipment like face respirators during a pandemic once supply chains of known-good equipment are available. How difficult would it be for this single product line to be validated by someone at Amazon?
