We're glad to hear that you're breathing happy with Febreze, Santi. We can assure you that our products go through many quality checks to ensure that the weight listed reflects the fill level of the liquid. It may be helpful to know that the space above the liquid is occupied by nitrogen, the propellant we use so that you're able to spray the product out of the can. We'd be happy to answer any questions you may have, so please know that you're always welcome to give us a call at (800) 308-3279.

Thank you for your review, Emilee. Febreze AIR has odor-eliminating technology designed to surround and destroy odors, leaving a light scent behind. The length of time the scent lasts depends on a couple of factors, such as the size of the room, ventilation and temperature. Please give us a call at (800) 308-3279, so we can help you further.
