What's the smell of air freshener?
The flowers are usually fragrant, such as rose, jasmine, Lily fragrance...
The smell of lavender can help sleep, but I think it's better to use essential oils. Drop one or two drops before going to bed, then fumigating with an aromatherapy lamp or a drop in the shower is a good result.
Better not buy it. It smells good and it's bad for you. It is impossible to buy toilet water spray. Can the old brand liushen. The water and toilet water according to the ratio of 40:1 with a good room, ground evenly sprayed into the spray bottle (especially the room, dead) and then close the doors and windows for 10 minutes, and then open the window ventilation. Sooner or later each time (if conditional, also can spray several times), can make the room air clean and fresh.
