Not into earloops, consumer products or foreign standards.. Current in stock, ships from/sold by Amazon.com picks would be:

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:

It's all about fit and personal preferences, but...
In terms of N95 respirators, some of the better current ships from / sold by Amazon.com options are:
3M 9105 | 3M 9211+ | 3M 9205 | 3M 9502+ | 3M 8210 | 3M 8511 | Moldex 4200N95 | Dräger 1750
EDIT: fixed Dräger link -- I added marketplace codes for ships from / sold by Amazon, but Dräger sells directly through Amazon like Halyard and BNX (Accumed), rather than Amazon being a distribution partner like their arrangement with 3M... So I needed to use Dräger's marketplace ID on the link.
