In my opinion, your best option would be either the DaBuddha Vape or the Silver Surfer Vape. They both have an available aromatherapy dish that worked wonders when I lived in a dorm. I was constantly getting compliments on how nice my room smelled

The essential oils available from the manufacturer do a wonderful job of covering up any smells. I actually find that the aromatherapy works pretty well. Citrus or mint will be very invigorating and helps wake you up, while something like lavender is quite relaxing at the end of a long day.
