Honeywell hepa air purifier with
the filter removed, added my own
carbon filter. Runs when my flowering
room lights are off, and door closed.
At lights on, the door gets opened, scrubber
is turned off, and i use an ozium time mist
to mask any smell. This unit is outside
my flowering room, mounted on the wall.
I've tried quite a few masking scents.
The air scrubber works surprisingly well.
The air mister too, although i've never been able to
get it 100% scent free, but i don't
need to be 100% stealthy either.
The time mist runs 24/7 spraying every 15 minutes.
In the winter, temps stay low enough to keep the door
closed during lights on, then it's about 95% scent free.
