Why Air Fresheners Might Be Making Your Air Quality Worse

Masking vs. Solving

Air fresheners, whether plug-in, spray, gel, or diffuser, work by adding fragrance compounds to the air. These compounds are VOCs: volatile organic chemicals that you inhale alongside whatever was causing the original odor. The source of the smell is still there. You just cannot detect it anymore because the fragrance chemicals are overpowering it. Common air freshener ingredients include formaldehyde, phthalates, and dozens of synthetic fragrance compounds, many of which are respiratory irritants.

A Sign Something Else Needs Attention

If you are using air fresheners to cover a persistent odor, that odor has a source: moisture, mold, poor ventilation, cooking residue, or accumulated allergens. Addressing the source removes both the smell and the need for the air freshener. The assessment identifies what is producing the odor and what to change.
