Lowering lead dust in older homes with portable air filters
Official title: Reducing Lead Dust Exposure and Childhood Blood Lead Levels in Older Housing in Michigan
Run by Michigan State University · NCT07485608 · Data updated 2026-11-12
This project will test whether portable air filters in older homes can reduce lead dust and lower blood lead levels in young children with elevated readings.

Is this trial a fit for you?
✓Likely a good fit
Children under seven years old who live in homes built before 1978, have blood lead levels above 5 µg/dL, and sleep at home during the two-month intervention are ideal candidates.
✕Probably not a fit
Children living in newer housing, whose lead exposure comes mainly from non-indoor sources, or whose medical conditions affect lead metabolism may not see benefit from home air filtration alone.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
In collaboration with local health departments, the team will enroll 40 households with children under seven who have blood lead levels above 5 µg/dL and live in homes built before 1978. Portable air filtration (PAF) units will be placed in participating homes for a two-month intervention. The study measures lead in suspended dust, floor dust, and children's blood before the intervention, at midpoint, and after two months to see if reductions in dust correspond to lower blood lead levels. Results will be used to develop evidence-based guidance for wider public use of PAF to reduce lead exposures.
Why it matters
Potential benefit: If successful, using portable air filters could lower indoor lead dust and help reduce children's blood lead levels, decreasing risks of lead-related health problems.
How similar studies have gone: Portable air filtration has been shown to reduce airborne particulate matter in homes, but direct evidence that it lowers household lead dust and children's blood lead is limited.
