We maintain a lawn for a nursing home. Within the past month it is mandatory for our guys to wear masks . They never enter the building, but when they are cleaning near the building they have to wear a mask. We have N95 masks that they wear. Today the supervisor that deals with us said the guys have to wear KN95 masks. N95 are certified by USA & KN95 are certified by China. I go to Amazon to look at the price difference - all that comes up are KN95 masks. I used google & Yahoo & nobody carries N95. WTH? have we stepped into the twilight zone or what? I'm apologizing in advance for those that say don't wear a mask there. We're a small company, It's one of our biggest clients & we might as well close the doors down to our business. Has all of America bought into China Rules?
