Air fresheners make me sneeze. I keep seeing adverts for them so I looked it up online. Not good:

Air fresheners typically contain a complex, unregulated mixture of synthetic chemicals and volatile organic compounds (VOCs). Common ingredients include formaldehyde, phthalates (which act as hormone disruptors), petroleum distillates, and benzene derivatives. These are often dissolved in solvents like isopropyl alcohol to disperse the scent.

There is more, but I didn’t want to use too much of this quotation from Google.

Just think of your health before you spend your money.
