The idea of air-purifying plants stems primarily from a 1989 NASA study that examined how plants could filter certain harmful substances from the air in enclosed spaces. Since then, many plant enthusiasts and sellers have embraced the concept. But what's the real story?
In reality, the effect of houseplants on indoor air quality is limited. Scientists point out that you would need hundreds of plants per square meter (!) to achieve the same effect as a well-ventilated room. In short: a houseplant is no substitute for fresh air from outside.
That doesn't mean air-purifying plants are nonsense. They do contribute to a pleasant living environment, increase humidity slightly, and are good for our mental health. And that's perhaps the most important benefit.
Below you will find a selection of plants that are not only often mentioned for their air purifying properties, but are also easy to care for.
With its glossy leaves and elegant white flowers, the peace lily ( Spathiphyllum ) is a real eye-catcher in your home. It's said to filter benzene, formaldehyde, and other pollutants from the air. It also increases humidity – ideal for dry spaces. Note: It's toxic to pets.
This hardy classic is nearly indestructible and thrives even in dark corners. Unique: Sansevieria converts CO₂ into oxygen at night, making it perfect for the bedroom. Note: the Mother-in-law's Tongue grows slowly but lives a long time. It appreciates a little neglect.
Easy, fast-growing, and nearly indestructible. The spider plant ( Chlorophytum comosum ) produces small "baby plants" on shoots. An ideal starter plant for beginners and an air-purifying powerhouse that, according to some studies, filters formaldehyde from the air.
This airy palm from Madagascar is known by several names— Dypsis lutescens , Chrysalidocarpus lutescens , Areca palm—but they're all the same golden cane palm. It adds a tropical touch to your living room or home office, but can also be placed in the bathroom (provided it has enough light). It increases humidity, which is beneficial for your skin and respiratory system. Place it in a bright spot, water it regularly, and you'll enjoy it for years to come.
