Potted plants do not improve indoor air quality: a review and analysis of reported VOC removal efficiencies.
TL;DR: The focus should shift the focus from potted plants’ (in)abilities to passively clean indoor air, and instead investigate VOC uptake mechanisms, alternative biofiltration technologies, biophilic productivity and well-being benefits, or negative impacts of other plant-sourced emissions, which must be assessed by rigorous field work accounting for important indoor processes.

Modelling consortium for chemistry of indoor environments (MOCCIE): integrating chemical processes from molecular to room scales
Manabu Shiraiwa,Nicola Carslaw,Douglas J. Tobias,Michael S. Waring,Donghyun Rim,Glenn Morrison,Pascale S. J. Lakey,Magdalena Kruza,Michael von Domaros,Bryan E. Cummings,Youngbo Won +10 more
TL;DR: The development of a modelling consortium for chemistry in indoor environments that connects models over a range of spatial and temporal scales is reported, opening up an avenue for development of comprehensive and integrated models with representations of various chemistry in indoors environments.

Improving Predictions of Indoor Aerosol Concentrations of Outdoor Origin by Considering the Phase Change of Semivolatile Material Driven by Temperature and Mass-Loading Gradients.
TL;DR: In this article, the authors used an explicit thermodynamic indoor aerosol model to simulate outdoor-to-indoor aerosol repartitioning typical for residential and office buildings across the 16 U.S. climate zones over an annual time horizon.

TL;DR: In this article , the authors hypothesize that ozone reacts on indoor surfaces to form semi-volatile ROS, in particular organic peroxides (OPX), which partition to airborne particles.

TL;DR: Researchers developed an effective mass accommodation coefficient (αeff) to simulate organic film formation and growth on indoor surfaces, showing excellent agreement with a comprehensive kinetic model, but highlighting the impact of bulk diffusivity and condensed-phase reactions on film growth and deposition velocity.
