I saw an old post on here saying that the dr puri heat stamp branding makes the mask useless. Does anyone have information on this? I couldn’t find anything online. Wellbefore masks which I also love seem to have heat stamp branding too so it worried me!

My lovely mask bloc unfortunately only has 3M auras which are too big for me.
My recent masks were the Fluidshield Halyard N95s (orange ones) (unsure if to call them duckbills but they do have that shape) but holy cow are they too expensive for me now, they’re like $40+ not even taking into account shipping.

I think the most I can do is $35 honestly.
I’m a bit skeptical to order from Amazon 1. Goes against my ethics 2. Scared of getting counterfeit masks but I may have to just go on there.
Any recommendations or anything?

Also I like the BNX duckbill N95s has anyone had success with them (not counterfeit/tested for effectiveness)? These seem fine but I wish they were available elsewhere…I’m going to have to take a leap too because whatever I buy MUST fit since I have such a limited spending amount.

All help is being appreciated. Hope I don’t come off as too picky or ungrateful…
