Review on Portable Purifier Eliminator Charging Bedroom by Anna Reed

I needed an air purifier because of my new roommates. She usually smokes in a room with all windows closed. So I would think it would be nice to have something like an air purifier or a filler. Because I really hate the smoky smell but when I first got my hands on this shipment it was so so so small. above my expectations. Tried 15 minutes. nothing seems to change? Do I have to try for at least 30 minutes? Or longer? Or do I need a stronger cleaner? Very disappointed. I must be realized before I give this command.
