Home Interventions Are Effective at Decreasing Indoor Nitrogen Dioxide Concentrations

(Indoor Air: International Journal of Environment and Health) A study was conducted to evaluate the efficacy of reducing indoor nitrogen dioxide (NO2) concentrations in homes with unvented gas stoves through three interventions: (1) replacement of gas stove with electric stove, (2) installation of ventilation hood over existing gas stove, and (3) placement of air purifiers with HEPA and carbon filters. Results showed that stove replacement resulted in a 51% and 42% decrease in median NO2 concentration at 3 months follow-up in the kitchen and bedroom, respectively, while air purifier placement resulted in a 20% decrease in median NO2 concentration in the kitchen at 3 months follow-up. Ventilation hood installation did not significantly change NO2 concentrations.
