Finding F-1759
“The air-filter intervention showed a 67% (95% CI: 50% to 77%) reduction in indoor PM2:5, but no change was observed with the improved-technology woodstove intervention.”
Structure
- Factor
- Particulate matter (PM₂.₅ and PM₁₀)
- Intervention
- Air filtration and air purifiers
- Setting
- home
- Study design
- randomised placebo-controlled trial in homes heated with wood stoves: households received a portable air filter, a changeout to an improved-technology wood stove, or a placebo filter, with indoor fine particulate matter and children's lung function measured through the heating season (class 2)
- Effect
- difference 67 (50–77)
- Caveat
- the filter lowers what is already in the room; the stove changeout, which acts on the source, did not
