Air freshener
From Wikipedia, the free encyclopedia
Air fresheners are consumer products that mitigate unpleasant odors in indoor spaces. They work in one of five ways:
- Absorption: Adsorbents like activated charcoal or silica gel may be used to absorb offending, chemical odors.
- Chemical neutralization: Substances such as rubber may be used for some odors.
- Disinfection. Odors caused by bacterial activity can be eliminated by disinfectants like ozone, TEG or bleaching agents containing hydrogen peroxide, chlorine or hypochlorites.
- Masking: Many "fresheners" obscure odors with a fragrance.
- Anesthetization: Some air fresheners use anesthetics to dull the sense of smell.
