what is an"Air-freshener"?

Answer 1

Air fresheners are consumer products that mitigate unpleasant odors in indoor spaces. Such products include candles, aerosoles, potpourri and gels. [1] 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.
