Nanosized titanium dioxide particle emission potential from a commercial indoor air purifier photocatalytic surface: A case study.

ABSTRACT: Background: Photocatalytic air purifiers based on nano-titanium dioxide (TiO ₂) visible light activation provide an efficient solution for removing and degrading contaminants in air. The potential detachment of TiO ₂ particles from the air purifier to indoor air could cause a safety concern. A TiO ₂ release potential was measured for one commercially available photocatalytic air purifier "Gearbox Wivactive" to ensure a successful implementation of the photocatalytic air purifying technology. Methods: In this study, the TiO ₂ release was studied under laboratory-simulated conditions from a  Gearbox Wivactive consisting of ceramic honeycombs coated with photocatalytic nitrogen doped TiO ₂ particles. The TiO ₂ par
