Honeywell DF300 N95 Flatfold Disposable Respirator- Box of 20, White https://www.amazon.com/dp/B08YJ3HNN7/ref=cm_sw_r_cp_api_glt_fabc_SV5T2YQA078BWMJ7A6TJ
Honeywell N95, these things are pretty good! Amazon is an authorized dealer as well!
Indeed. Lots of great NIOSH-approved respiratory protection products up on Amazon. Distribution partner for 3M Halyard. Stick with major domestic brands and "ships from, sold by amazon.com" items only. Avoid marketplace sellers, foreign manufacturers, and foreign standards (KN95, KF94, FFP2 are risky bets) -- Current in stock recommendations:
