About

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.

Full description

Invesitigators measured indoor air pollutants, including particulate matter, bioaerosols, gaseous pollutants, in households and health outcomes, including lung function, respiratory symptoms, fractional exhaled nitric oxide, blood pressure, biomarkers, urinary heavy metals, and polycyclic aromatic hydrocarbons, in susceptible group, such as asthma and COPD patients.
