Want to lift up your mood and freshen your room at the same time? Why not use a fragrance oil burner?
I prefer it to air freshener and aerosol.
My perfect working environment: fresh scent from a few drops of my favorite essential oil + classical music. Ooooohhhh... floating...
I also like to light it 1 hour before I go to bed. Remember to blow your candle before you sleep... you wouldn't want the same incident happening to you as it happened to Phoebe in Friends ^^
