Air fresheners are consumer products designed to reduce unwanted indoor odors, emit pleasant fragrances, or both. First introduced in modern commercial formats in 1946, they are used in homes, offices, bathrooms, and vehicles to shape the ambient mood. Rather than filtering the air like a purifier, they function by introducing volatile compounds into the environment. How Air Fresheners Work
Air fresheners interact with your senses and the surrounding air through four primary mechanisms:
Masking: Layering a strong, pleasant scent over a bad odor to overpower it.
Neutralizing: Altering the pH of the odor molecules to change them into an odorless salt form.
Trapping: Using chemical compounds like cyclodextrin to capture and lock away bad odor molecules.
Anesthetizing: Utilizing chemical agents that temporarily reduce your nose’s sensitivity to bad smells. Common Product Types
