ST, It's not easy to read but best I can tell the approval # is either 84A-7678 or 84A-7878. One of the numbers belongs to Honeywell for a half mask and the other belongs to Xiantao Zhongyi for Model ZYB-12 N95 Filtering Facepiece with Exhalation Valve, Air Purifying Respirator. The NIOSH cert on that site goes with the Chinese company.
