What the Science Says"},"content":{"rendered":"\n<div class=\"wp-article\">\n<p>\n    Houseplants make homes feel calmer, greener, and more inviting\u2014but can they\n    really clean the air? The answer is more nuanced than many popular claims\n    suggest.\n  <\/p>\n\n  <p>\n    The idea that houseplants act as natural air purifiers gained attention after\n    NASA research in the late 1980s showed that certain plants could remove\n    volatile organic compounds (VOCs) from the air in sealed laboratory\n    environments. While those findings were scientifically sound, laboratory\n    conditions are very different from everyday homes.\n  <\/p>\n\n  <h2>Why Laboratory Results Don't Tell the Whole Story<\/h2>\n\n  <p>\n    Most experiments demonstrating air-cleaning abilities use small, sealed\n    chambers with unusually high concentrations of pollutants. These controlled\n    conditions allow researchers to compare different plant species but do not\n    accurately represent real homes, where fresh air constantly enters through\n    ventilation, doors, windows, and small gaps in the building.\n  <\/p>\n\n  <p>\n    Researchers have found that the natural air exchange in a typical home\n    removes pollutants much more effectively than a few potted plants alone.\n    Estimates suggest an unrealistically large number of plants would be needed\n    to match the air-cleaning effect of normal household ventilation.\n  <\/p>\n\n  <figure style=\"text-align:center;\">\n    <picture><source srcset=\"https:\/\/gecco.org.uk\/blog\/wp-content\/uploads\/2026\/06\/file-20260423-57-62yp8s1.webp \"  type=\"image\/webp\"><img src=\"https:\/\/gecco.org.uk\/blog\/wp-content\/uploads\/2026\/06\/file-20260423-57-62yp8s1.jpg\" class=\" sp-no-webp\" alt=\"Houseplants indoors\" decoding=\"async\" style=\"max-width:100%;height:auto;border-radius:6px;\"  > <\/picture>\n    <figcaption>\n      Can houseplants really purify the air?\n    <\/figcaption>\n  <\/figure>\n\n  <h2>Where Houseplants Do Help<\/h2>\n\n  <p>\n    Although houseplants are not a replacement for proper ventilation or air\n    filtration, they still offer several valuable benefits. Research suggests\n    they can:\n  <\/p>\n\n  <ul>\n    <li>Create a more relaxing and attractive living environment.<\/li>\n    <li>Improve psychological well-being and reduce stress.<\/li>\n    <li>Increase people's connection with nature indoors.<\/li>\n    <li>Contribute modestly to indoor humidity in some situations.<\/li>\n  <\/ul>\n\n  <h2>The Best Ways to Improve Indoor Air Quality<\/h2>\n\n  <p>\n    Experts recommend focusing first on reducing pollution at its source rather\n    than relying on houseplants alone.\n  <\/p>\n\n  <ul>\n    <li>Open windows when outdoor air quality allows.<\/li>\n    <li>Use kitchen and bathroom extractor fans.<\/li>\n    <li>Choose low-emission cleaning and household products.<\/li>\n    <li>Repair damp areas and mould problems promptly.<\/li>\n    <li>Use a high-quality HEPA air purifier if cleaner indoor air is needed.<\/li>\n  <\/ul>\n\n  <h2>Should You Keep Houseplants?<\/h2>\n\n  <p>\n    Absolutely. While houseplants should not be considered a practical solution\n    for serious indoor air pollution, they provide aesthetic, emotional, and\n    wellbeing benefits that make homes more enjoyable places to live.\n  <\/p>\n\n  <figure style=\"text-align:center;\">\n    <picture><source srcset=\"https:\/\/gecco.org.uk\/blog\/wp-content\/uploads\/2026\/06\/file-20260423-57-j2m53t1.webp \"  type=\"image\/webp\"><img src=\"https:\/\/gecco.org.uk\/blog\/wp-content\/uploads\/2026\/06\/file-20260423-57-j2m53t1.jpg\" class=\" sp-no-webp\" alt=\"Relaxing home with houseplants\" decoding=\"async\" style=\"max-width:100%;height:auto;border-radius:6px;\"  > <\/picture>\n    <figcaption>\n      Houseplants help create a relaxing and welcoming home environment.\n    <\/figcaption>\n  <\/figure>\n\n  <h2>Final Thoughts<\/h2>\n\n  <p>\n    Houseplants are wonderful additions to any home, but they should be viewed\n    as companions to good indoor air practices\u2014not replacements for proper\n    ventilation or filtration.
