Would you as a firefighter wear these?

[u/MightAsswell]

I'm hoping to become a firefighter. In situations where I'm not wearing a SCBA, but there's still smoke or ash around, I think something like this would be a good idea to wear to help prevent inhaling some of the toxic shit in the air. Has anyone tried this before?

Mate, if you're worried about inhaling toxins and pollutants, you need to wear PPE properly approved by a standards process, like SCBA, a PAPR mask, or n95 masks, not random snake oil trinkets you see on Wish dot com.

There is zero chance these are as effective as PPE tested and approved by ANSI, NFPA, NIOSH, Underwriter Labs, etc.
