But what often gets ignored is that the air inside our homes can be just as polluted, sometimes even worse. Limited ventilation, cooking fumes, dust, humidity, incense and pet dander allow pollutants to accumulate indoors, especially in compact urban homes. This is why so many people are now asking whether houseplants can <strong>i<\/strong>mprove indoor air quality in a meaningful way.<\/p>\n\n\n\n<p>A recent experiment by a teenager in California has once again sparked interest by suggesting that English ivy might reduce certain biological pollutants indoors. But can houseplants really improve indoor air quality in Indian households or is the hype misleading? Let\u2019s look at the science and the reality.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"432\" src=\"https:\/\/www.pranaair.com\/blog\/wp-content\/uploads\/2025\/11\/shutterstock_2605045703-1.png\" alt=\"\" class=\"wp-image-138273\" style=\"width:960px;height:auto\" srcset=\"https:\/\/www.pranaair.com\/blog\/wp-content\/uploads\/2025\/11\/shutterstock_2605045703-1.png 600w, https:\/\/www.pranaair.com\/blog\/wp-content\/uploads\/2025\/11\/shutterstock_2605045703-1-300x216.png 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-the-experiment-showed\"><span class=\"ez-toc-section\" id=\"What_the_Experiment_Showed\"><\/span>What the Experiment Showed<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In the viral experiment, a student placed mouldy bread and dog waste inside a sealed container. After adding a potted English ivy plant and waiting 12 hours, the results reportedly showed:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>78% reduction in mould levels<\/li>\n\n\n\n<li>94% reduction in microscopic faecal particles<\/li>\n<\/ul>\n\n\n\n<p>These pollutants, known as bioaerosols, include tiny airborne particles from microbes, pets, damp areas and organic waste. They can trigger allergies, asthma and other respiratory symptoms.<\/p>\n\n\n\n<p>The dramatic results immediately caught attention, but they also raised questions about whether similar results are possible in real lived-in homes.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"600\"

Indoor Air Quality<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Several natural processes may help houseplants improve indoor air quality in small or controlled spaces:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Passive Dust Collection<\/strong><br>Leaves act as surfaces where dust and particles settle.<\/li>\n\n\n\n<li><strong>Soil Microbes Breaking Down VOCs<\/strong><br>Studies in Frontiers in Built Environment suggest soil microbes can break down certain volatile organic compounds from furniture, paints and cleaning agents.<\/li>\n\n\n\n<li><strong>Humidity Regulation<\/strong><br>Plants help stabilise indoor humidity, which may indirectly reduce mould formation.<\/li>\n<\/ol>\n\n\n\n<p>These mechanisms show that plants can contribute to a healthier indoor micro environment.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"535\"

Limitations<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Despite their benefits, houseplants cannot single handedly improve indoor air quality at the level Indian homes usually require.<\/p>\n\n\n\n<p>Large organisations, including the American Lung Association, note that:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Most experiments are conducted in sealed environments<\/li>\n\n\n\n<li>You would need dozens of plants per room for measurable results<\/li>\n\n\n\n<li>Plants do not remove PM2.5 or smoke<\/li>\n\n\n\n<li>Plants cannot effectively filter gases like NO2 or SO2<\/li>\n<\/ul>\n\n\n\n<p>This is why experts recommend using plants as a supplementary element, not the primary solution.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full

for PM2.5, PM10 and smoke (Explore Prana Air\u2019s HEPA filtration systems: <a href=\"https:\/\/www.pranaair.com\/in\/fresh-air-machine\/\">https:\/\/www.pranaair.com\/in\/fresh-air-machine\/<\/a>)<\/li>\n\n\n\n<li>Ventilation during lower AQI hours<\/li>\n\n\n\n<li>Humidity

approach targets different pollutants instead of relying on one method alone.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-using-plants-effectively\"><span class=\"ez-toc-section\" id=\"Using_Plants_Effectively\"><\/span>Using Plants Effectively<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>If you want to enhance your indoor environment with plants:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Choose hardy, low maintenance species like areca palm, pothos, money plant and snake plant<\/li>\n\n\n\n<li>Avoid overwatering to prevent mould<\/li>\n\n\n\n<li>Clean leaves so they continue collecting dust<\/li>\n\n\n\n<li>Ensure adequate indirect sunlight<\/li>\n\n\n\n<li>Check plant toxicity if you have pets or small children<\/li>\n<\/ul>\n\n\n\n<p>Beyond air quality benefits, plants also improve mood, aesthetics and indoor comfort.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-key-takeaway\"><span class=\"ez-toc-section\" id=\"The_Key_Takeaway\"><\/span>The Key Takeaway<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The viral experiment is exciting and shows that plants can reduce certain pollutants in controlled conditions. However, for Indian homes dealing with PM2.5, cooking smoke, dust and seasonal humidity, houseplants work best as part of a larger strategy designed to improve indoor air quality instead of functioning alone.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Final_Word\"><\/span>Final Word<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Indoor air pollution is a growing concern across India. While plants add beauty and support indoor wellness, the foundation for truly clean air lies in understanding your environment and using proven tools alongside natural ones. This balanced approach will genuinely improve indoor air quality for your home and your family.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When people in India think of air pollution, they usually imagine outdoor smog, vehicle emissions and rising PM2.5 levels.
