In college they called something like this a "snuggly" LOL
It was a toilet paper role with a fabric dryer sheet in it. Hid many
"smells" folks did not wish found LMBO.
Did not really filter the air.To the best of my knowledge. But
the smell and smoke was less noticeable.
Any inventors on this list? Some sort of easily portable
system, where the cigarette, pipe, or whatever was actually
encased in a
tube, so that all of its smoke went straight to a filter, and
not into the
air, and there was an additional tube into which the smoker
their smoke would be a great thing. Something small and
light, to fit into
a waist belt or backpack (not unlike the Camelbak
hydrations systems which
have become popular)
