Finding F-1667
“The particle filters reduced the median concentration of PM2.5 from approximately 8 to 4 μg/m3 and the particle number concentration from 7669 to 5352 particles/cm3.”
Structure
- Factor
- Particulate matter (PM₂.₅ and PM₁₀)
- Intervention
- Air filtration and air purifiers
- Setting
- home
- Study design
- crossover filtration study in the homes of elderly subjects: custom-built particle filter units run in the living room and the bedroom, with fine particles and particle number measured and cardiovascular and lung outcomes recorded before and during each exposure scenario (class 2)
- Effect
- median
- Caveat
- the study found no statistically significant effect of the filtration on microvascular or lung function or on the systemic inflammation markers
