Summary

Invesitigators conducted a double-blind, randomized, and crossover study to investigate the effects of PCO and PCO + filters interventions on indoor air pollutants in households and health outcomes in susceptible group, such as asthma and COPD patients.

Conditions

  • Asthma (Diagnosis)
  • COPD (Chronic Obstructive Pulmonary Disease)

Interventions

OTHER

Air purfiers with photocatalytic oxidation (PCO)

PCO was proved to decompose gaseous pollutants in chamber studies, while there is no study investigate the effects in real-world. We used PCO air purifiers in households for two weeks.

OTHER

Air purfiers with photocatalytic oxidation (PCO) + filters

PCO was proved to decompose gaseous pollutants in chamber studies, while there is no study investigate the effects in real-world. We used PCO and filters air purifiers in households for two weeks, to understand the effects comparing with PCO.
