I generally stay away from chemical fresheners, but was desperate for something to deoderize my basement carpet. Febreeze Air Effects gave me a massive headache almost immediately. It smells chemically, and makes me worry about what kind of toxic chemicals are in it. I will NEVER by a Febreeze product again. A mixture of vinegar and baking soda worked wonders on my carpet and made feel better about the air quality in my hime.

So strong smelling. Awful. Gives me such a head ache.
