Covering smoke with something nicer doesn't remove it.
Every spray, every candle, every plug-in does the same thing: pushes a new scent into the room and hopes you stop noticing the old one. The smoke molecules? Still in your couch. Still in your curtains. Still in the fabric — untouched.
That's why the room smells like two things instead of one. That's why it's back an hour later. That's why no amount of spraying ever fixes it — because masking is the problem.
This works the other way around. Plant-based enzymes in an ultra-fine nano mist penetrate deep into fabric, curtains, and air — and break the odor compound apart at source. It doesn't compete with the smell. It removes what's causing it.
