Abstract

Wood burning for residential heating is prevalent in the Rocky Mountain regions of the United States.
Studies have shown that wood stoves can be a significant source of PM2.5 within homes.
In this study, the effectiveness of an electrostatic filter portable air purifier was evaluated 1 in a home where a wood stove was the sole heat source and 2 in a home where a wood stove was used as a supplemental heat source.
Particle count concentrations in six particle sizes and particle mass concentrations in two particle sizes were measured for ten 12-hour purifier on and ten purifier off trials in each home.
Particle count concentrations were reduced by 61–85 percent.
Similar reductions were observed in particle mass concentrations.
These findings, although limited to one season, suggest that a portable air purifier may effectively reduce indoor particulate matter concentrations associated with wood combustion during home heating.
