Fume Fading
Fume Fading / Ozone Fading (Carpet)
Floor Detective® Claims and Conditions Guide
Summary
Fume fading, including ozone fading, is an environmentally induced appearance condition that occurs when airborne oxidizing gases chemically alter carpet dye molecules at the fiber surface. Reactive gases such as nitrogen dioxide (NO₂) and ozone (O₃) may gradually oxidize dyes, producing permanent color change that commonly develops independent of direct sunlight exposure. The condition is influenced by airflow behavior, humidity, dye chemistry, environmental exposure, and HVAC distribution patterns rather than installation or maintenance practices. Fume fading commonly affects exposed yarn tips first and may appear as gradual, airflow-related color change rather than isolated staining or spotting. The condition affects carpet color only and does not independently reduce fiber strength, backing integrity, or structural durability. Fume fading may resemble fading or chemical degradation, but often develops in areas without direct sunlight and follows environmental airflow patterns rather than topical exposure. See also Fading, Chemical Degradation, and Carpet Problems for broader context.
