Can Indoor Plants Really Improve Air Quality?
Indoor plants can make your home greener, more inviting and potentially contribute to a healthier indoor environment. However, their ability to clean the air should not be overstated. Some laboratory studies have shown that plants can absorb certain pollutants, but research suggests that ordinary potted plants are not effective enough to significantly improve air quality in typical homes.A 2019 review published in the Journal of Exposure Science and Environmental Epidemiology found that an impractically large number of potted plants would be needed to match the air-cleaning effect of normal air exchange in buildings.
For better indoor air quality, consider combining indoor plants with these simple measures:
- Ensure proper ventilation: Open windows when outdoor air quality permits to allow fresh air to circulate.
- Clean regularly: Remove dust from furniture, floors, carpets and other surfaces to reduce indoor pollutants.
- Control humidity: Fix water leaks and address damp areas to prevent mould growth.
- Avoid indoor smoke: Minimise exposure to cigarette smoke, incense and other sources of indoor pollution.
- Use air purifiers: Consider an appropriately sized air purifier with a HEPA filter to help remove airborne particles.
