10 plants to purify the air in the house – Indoor plants – Plants to purify the air

In our homes, air quality is not always optimal. There can be many pollutants: cigarette smoke, city smog or compounds released from paints and plastics. To make the environment healthier you can act on several fronts, but the most economical and immediate is the inclusion of plants capable of filtering the air by “capturing” the harmful agents. Here are the best!

purificare l'aria piante


SansevieriaVery fashionable, in all its varieties! Whether it’s the trifasciata (with its flat, elegantly wavy leaves) or the cylindrica (which has them similar to long cones), it will not fail to amaze us with its charm and adaptability.

Perfect for those who tend to forget to care for their own green: they require occasional irrigation and live well in bright or shady environments, varying only the speed of growth.

It is perfect for the internal hallways, entrances and lounges, but especially for the bedrooms. In addition to filtering the air from pollutants, it is able to continue to produce oxygen even during the night.

Anthurium andreanum

Anthurium andreanumHow can I not wish for it? Its shiny leaves create a magnificent contrast with the large heart-shaped spatas. The whole is really suitable for all contexts, from the most modern to the most traditional. They commonly have dark red inflorescences, with the yellow spadix in evidence. More and more often, however, there are variations in pink, for more delicate settings, or in elegant white.

Cultivation is not very easy: we must guarantee heat and a high and constant level of humidity, but avoid stagnation. However, it is suitable for dark rooms because it likes half a shade.

It is an excellent aid in reducing the impact of formaldehyde, toluene and ammonia.


Orchidee Orchids always give a lot of satisfaction even in apartments: many varieties (such as phalaenopsis and dendrobium) are able to bloom well, year after year, especially if they receive enough light and heat.

They are perfect in the living room, but are also suitable for open bathrooms and bedrooms.

It is precisely when we sleep that we get the maximum benefit from them: they are among the few plants capable of emitting, in addition to carbon dioxide, also good quantities of oxygen. They also capture many different types of pollutants, thus helping to improve the quality of our sleep.

Dracaena deremensis

Dracaena deremensisDracaena is one of the most common indoor plants. It is appreciated for the essentiality of its forms, and for the different colors of the foliage: from homogeneous green to variegated, to striped in bright pink. It is also among the easiest to cultivate: it requires frequent irrigation, but making sure that the substrate is perfectly draining. It does not need particularly bright rooms, but naturally with a good exposure it grows faster.

It is ideal to keep in bedrooms and kitchens as it is an excellent filter for toluene, formaldehyde and benzene.

Ficus Benjamin

Ficus Benjamin Its broad and light shape makes it one of the best plants to give a touch of liveliness to a living room or a large kitchen. We can choose between the dark green leaf variety or the variegated one according to our tastes and the setting.

It requires a light substrate, perfect drainage and frequent irrigation, as well as a high level of ambient humidity (frequent nebulisations are useful). It lives well in bright rooms, but it also bears the half shade.

It is appreciated for its ability to seize in stomata toluene, formaldehyde, benzene and ammonia.


SpatiphyllumPerfect for giving an exotic touch to our rooms, resting on the ground or as a centerpiece.

In winter we will appreciate the beautiful dark green leaves, elongated and shiny. In the summer we will see the beautiful and elegant spatas appear, similar to light feathers.

Let’s choose a pot not too big and a rich, but well drained, soil. Watering should be frequent, like fertilizing (especially in the summer); it likes bright rooms with a high humidity (perfect kitchens and bathrooms with windows).

Very effective against organic compounds and formaldehyde.

Sturdy and elastic ficus

Ficus elastica Here are two other very popular ficuses in homes. These species have a very vertical deportment and large, oval, shiny and leathery leaves. The most common varieties have dark green, but there are also those variegated in the cream and with pink streaks. The cultivation is very simple: it wants quite rich soil, but well drained, frequent irrigations and fertilizations, as well as high ambient humidity. They are perfect for an entrance hall, a living room or even in the landings.

Both are excellent for reducing the impact of cigarette smoke and paint and plastic residues.

Dracaena margined

Dracaena marginataBeautiful, easy and very effective!

Thanks to its vertical posture and its essential and modern appearance, it adapts perfectly to contemporary environments. It requires only a fairly bright room, regular irrigation and a good level of ambient humidity. We will only have to pay attention to water stagnations that could cause the only frequent inconvenience: root rot.

However, it will reward us adequately: it is really one of the plants considered best for purifying the air of domestic environments. Let’s take it seriously, especially if there are smokers in the family.


Edera So common, but so useful! It is in fact among the best ever as an air purifier and is recommended by pulmonologists and experts to all those who suffer from asthma and allergic rhinitis. It is in fact able to “capture” many allergenic agents, significantly reducing the concentration in the air.

Let’s choose a variety with a limited development and with a small leaf, to be cultivated in small pots or hanging baskets, maybe combined with some flowering plants. We can keep it in the most frequented rooms of the house, such as the kitchen or the living room. But it is also perfect in the bedroom.

10 plants to purify the air in the house: Plant “spider”

Pianta “ragno” Who didn’t have one? It’s the easiest solution if you’re looking for something to put in a hanging basket, in a well-lit and warm area of your home. He wants a draining, acid-reacting soil that stays cool for a long time, but with excellent drainage. The growth is fast, as the propagation: it is sufficient to detach one of the many “offshoots” and bury it immediately.

In summer it can also be moved outside.

Chlorophytum comosum (as it is actually called) is perfect for reducing the impact of cigarette smoke and also absorbs good amounts of formaldehyde.
