Finding fine white powder under your vents can feel unsettling. You clean it up, yet it keeps coming back. Naturally, that raises concerns about air quality and home safety.
Fortunately, this issue is common. More importantly, most causes are identifiable—and fixable.
Why White Dust Around Vents Is So Common
First, understand this: your HVAC system constantly moves air. As it does, it also moves particles.
Over time, those particles settle around vents. In many homes, that buildup appears as fine white dust. Age, airflow, and system design all play a role.
Deteriorating Duct Liners: A Frequent Culprit
One of the most common causes is failing duct liner material. Many HVAC systems use fiberglass liners to reduce noise and insulate ducts.
