What are air-fresheners made of?

Ever wonder what air-fresheners are made of? How about that delicious apple scented one? Is that really apples or is it something else. I just read an article discusses the make-up of air fresheners and their effects on us and was flabbergasted... although not surprised.

Here's the short list:
  • Acetone
  • Butane
  • Isobutane(lighter fluid)
  • Petroleum gas
  • Propane
  • Benzene
  • Formeldahyde. 

All of these products cause cancer and are toxic to every single organ in your body including your heart, lungs and brain.
