How do air-purifying plants work? The complete explanation

Air-purifying plants are popular because they are not only beautiful, but also contribute to a fresher and more natural atmosphere at home. But how exactly does that work? And do plants really purify the air, or are they mainly a nice addition to your interior?

In this article, we explain how air-purifying plants work, which substances they can absorb, and which plants are suitable for the living room, bedroom, or office.

Do air-purifying plants really help?

Plants can absorb and process certain substances through their leaves, roots, and potting soil. In addition, they increase air humidity and bring a natural, calm ambiance into the home. The effect depends on the plant species, the number of plants, the space, and the ventilation.

Therefore, see air-purifying plants as a nice addition to a healthy indoor climate. Ventilation remains important, but plants can certainly contribute to a fresher feeling at home.

How do plants purify the air?

Air-purifying plants absorb substances from the air through their leaves. A part of this is processed by the plant itself, while microorganisms around the roots can also help break down certain substances in the potting soil.

Especially plants with a large leaf surface can contribute to a fresher living environment. Think of green houseplants with large leaves, such as Monstera, Areca palm, Dracaena, and Spathiphyllum.

Which substances can air-purifying plants absorb?

Various substances can be released indoors from furniture, paint, cleaning products, and materials. Air-purifying plants are often mentioned in combination with substances such as formaldehyde, benzene, and trichloroethylene.

It is important to remain realistic: plants do not replace ventilation or an air purifier. However, they can help make your interior feel greener, calmer, and fresher.
