ASIN B095FJ36H2 is the retail version, and should come in a retail box with retail (consumer) instructions. This is the same packaging you'd find at Home Depot, etc.
ASIN B09FM2P1KF is the commercial version, and should come in a inner carton of a case with commercial instructions.
The difference is purely in the packaging.
The commercial version will be labeled "For industrial/occupational use only. Not for consumer sale or use" due to the lack of consumer-oriented instructions that disclaim liability for use in hazardous environments. Consumers are assumed to not be using the product to the occupational standards that confer protection from hazardous environments, so the product instructions disclaim liability for such use. Legalese.
ETA: Note for amazon links, you can force the seller to ships from / sold by amazon with the m query string parameter and Amazon's own seller id, which is ATVPDKIKX0DER for Amazon US. The URL format is thus:
https://www.amazon.com/dp/<ASIN>?m=ATVPDKIKX0DER
For example:
https://www.amazon.com/dp/B09FM2P1KF?m=ATVPDKIKX0DER
The smid query string parameter only suggests the seller, if it is unavailable from that seller another will be chosen. The m parameter forces the seller, and the product will be displayed as unavailable if that seller has no inventory.
Also of note, Amazon does sell the 9210+, which are preferable due to tighter, more durable cloth straps. The ASIN is B0BCL5XZKQ
From what I’ve read, they don’t work well because they fog up almost immediately. I wear these: 3M Aura Particulate Respirator... https://www.amazon.com/dp/B09FM2P1KF?ref=ppx_pop_mob_ap_share
You just need to be Amazon savvy to purchase masks on Amazon. Amazon is often the most accessible option for many people, so I'd rather show people how to do it right than tell them it's not possible to do it.
Amazon is an authorized retailer of 3M Auras - you need to check that when you add your item to cart, it says both Ships from Amazon, Sold by Amazon a good trick for this one is to know that these NEVER go on sale or discount - if you're getting a steal of a deal, check your seller.
BNX sells on Amazon directly through their storefront, This should say Ships from Amazon Sold by BNX AccuMed OR if you're not getting it with Prime, it will say Ships from AccuMed, Sold by BNX AccuMed
BOTN also has an Amazon storefront BOTN purchases need to always say "Sold by BOTN KOREA" when adding to cart. Some options have Prime shipping and are "Ships from Amazon" but others with Ship and Sell from BOTN Korea.
Other KF94s like Good Manner are found on Amazon and aren't typically counterfeited because they already sell so cheaply, but getting familiar with the packaging helps prevent gray market purchases (typically not fakes, but just not intended to be sold to Western buyers.)
