Evaluate your specific family needs. Research indicates that the everyday activity of opening and closing lead-base painted windows creates friction that then allows microscopic lead dust to enter the air. This is of special concern in households built prior to 1978, with young children who crawl on the floor. Toddlers put their hands in their mouths, and after playing on the floor near a window, they can easily transfer the lead dust into their mouths. The ingested lead can travel through the bloodstream to a child’s developing brain, potentially causing neurobehavioral damage.
