Potted plants have demonstrated abilities to remove airborne volatile organic compounds (VOC) in small, sealed chambers over timescales of many hours or days. Claims have subsequently been made suggesting that potted plants may reduce indoor VOC concentrations. These potted plant chamber studies reported outcomes using various metrics, often not directly applicable to contextualizing plants’ impacts on indoor VOC loads. To assess potential impacts, 12 published studies of chamber experiments… 

Potted plants can remove the pollutant nitrogen dioxide indoors

Nitrogen dioxide (NO2) is a significant pollutant in both outdoor and indoor environments with exposure linked to serious respiratory illnesses, decreased lung function and airway inflammation. Here,

Air Cleaning Performance of Two Species of Potted Plants and Different Substrates

Potted plants have been reported to uptake VOCs and help ‘cleaning’ the air. This paper presents the results of a laboratory study in which two species of plants (Peace Lily and Boston Fern) and

The evolution of botanical biofilters: Developing practical phytoremediation of air pollution for the built environment

Indoor air quality is of emerging importance due to the rapid growth of urban populations that spend the majority of their time indoors. Amongst the public, there is a common perception that

Current State of Indoor Air Phytoremediation Using Potted Plants and Green Walls

Urban civilization has a high impact on the environment and human health. The pollution level of indoor air can be 2–5 times higher than the outdoor air pollution, and sometimes it reaches up to 100

Formaldehyde is a hazardous volatile organic compound (VOC) listed as a Group 1 carcinogen by the International Agency for Research on Cancer. The active green wall system is a promising technology

Textile Washing Conveys SVOCs from Indoors to Outdoors: Application and Evaluation of a Residential Multimedia Model.

TLDR
It is suggested that residential textile washing can be an important transport pathway to outdoors for SVOCs emitted to indoor air, with implications for human and ecological exposure.

Evaluating In Silico the Potential Health and Environmental Benefits of Houseplant Volatile Organic Compounds for an Emerging ‘Indoor Forest Bathing’ Approach

TLDR
It is found that β-costol is an organic compound, emitted in appreciable amounts by the houseplant Spathiphyllum wallisii, endowed with potential antiviral properties as emerged by the MD calculations in a SARS-CoV-2 Mpro (main protease) inhibition study, together with sesquirosefuran.

Adaptation of Indoor Health and Comfort Criteria to Mitigate Covid-19 Transmission in the Workplace

The research discussed the application of indoor health and comfort criteria that needed to be reviewed to create good indoor environmental quality and reduce the transmission of the Covid-19 virus

The Potted-Plant Microcosm Substantially Reduces Indoor Air VOC Pollution: I. Office Field-Study

Volatile organic compounds (VOCs) are major contaminants of indoor air, with concentrations often several times higher than outdoors. They are recognized as causative agents of “building-related

The Potted-Plant Microcosm Substantially Reduces Indoor Air VOC Pollution: II. Laboratory Study

Indoor air-borne loads of volatile organic compounds (VOCs) are usually significantly higher than those outdoors, and chronic exposures can cause health problems. Our previous laboratory studies have

Removal of Benzene by the Indoor Plant/Substrate Microcosm and Implications for Air Quality

The quality of the indoor environment has become a major health consideration, since urban-dwellers spend 80-90% of their time indoors, where air pollution can be several times higher than outdoors.

Assessment of volatile organic compound removal by indoor plants—a novel experimental setup

TLDR
An experimental test system to assess VOC removal by indoor plants which allows for an improved real-life simulation is developed and Hedera helix reaching a toluene removal rate of up to 66.5 μg/m2/h is proved.

TLDR
From these results, the incorporation of a large amount of biomass associated with indoor biofilters does not in itself lower indoor air quality.

Biofiltration of airborne VOCs with green wall systems—Microbial and chemical dynamics

TLDR
Results clearly show the benefits of active air circulation and optimized growth media in modern green wall systems, indicating that initial VOC removal was largely abiotic.

Indoor-Biofilter Growth and Exposure to Airborne Chemicals Drive Similar Changes in Plant Root Bacterial Communities

TLDR
Investigation of how bacterial communities on biofilter plant roots change over time and in response to VOC exposure showed differences in bacterial communities between soil-grown and biowall-grown plants and between bacterial communities from plant roots exposed to clean air and those from VOC-exposed plant roots.
