How air fresheners work

Air fresheners work primarily by releasing fragrant chemical substances to mask and neutralize unpleasant odors in the air. Their working principle can be summarized as follows:

1. Volatile Compounds: Air fresheners contain volatile compounds such as essential oils and alcohols. These compounds spontaneously evaporate into the air, releasing a fresh scent.

2. Chemical Reaction: The compounds in air fresheners react chemically with pollutants in the air. For example, some compounds can react with sulfides and oxides, thus neutralizing odors.

3. Adsorption: Some components in air fresheners have adsorption capabilities, adsorbing harmful gases, particles, and odor molecules from the air.

4. High-Temperature Catalysis: Some air fresheners contain catalysts. When air is heated, the catalyst accelerates the chemical reaction, decomposing harmful substances in the air and producing fresher air.
