Method's planet-friendly air refreshers give you a cleaner way to spray and freshen your home, free of dirty propellants, CFCs and dirty ingredients, featuring a non-toxic formula! Unlike many traditional aerosol air fresheners that are powered by petroleum-based propellant mixed in with the product, our air refreshers are powered by compressed air so all you get is a room filled with one of five fresh, nature-inspired scents. And the pressurized air technology gives you a continuous, even spray for maximum spraying power down to the last drop no drippy uneven sprays or wasted product. There's nothing dirty about that.
