10 best air purifying plants for the home

Do indoor plants purify the air?

Even a small number of indoor plants can help to improve air quality indoors. One mature, vigorous plant in a pot with a diameter of about 12-16 cm can do a good job of cleaning the air in a room of about 10 square meters.

Increasing the number of plants, their sizes, and and choosing good locations for them can significantly affect the air quality in your home. Remember that the larger the plant is, the greater the amount of leaf surface it will have, giving it a greater air cleaning ability. Your plants should be evenly spaced within each room and kept in areas with sufficient light and heat.

Also, make sure that your plants are healthy, as unhealthy plants have much less ability to purify air. And since the roots and microorganisms living in the soil also help neutralize harmful substances,  avoid stagnant water in the soil.

In today's world, the problem of cleaning the air in your home or apartment is becoming more and more important. Many harmful substances surround us, both outdoors and indoors. This is why people are increasingly trying to find plants that help purify air. Another benefit that you may remember from school is that plants absorb carbon dioxide and produce oxygen. And some kinds of houseplants can neutralize gases that are dangerous to humans.

What plants improve air quality?


Many of our grandmothers kept aloe plants in their homes. Aloe juice has medicinal properties, so it is widely used in folk medicine. But that is not aloe’s only useful property. Aloe cleans indoor air very effectively, and absorbs up to 90% of the formaldehyde inside the room the aloe is in.

There are many other plants that help to purify the air, and some are recommended by NASA.

What plants does NASA recommend?

In 1989, NASA launched a NASA Clean Air Study to determine the best indoor plants for cleaning ambient air on a space station. Scientists found that indoor air contains particles of harmful volatile organic compounds including trichloroethylene, benzene, ammonia and others. To clean the air, experts recommend placing certain plants in the rooms, as the right plants can neutralize up to 85% of indoor air pollution.

Anthurium andraeanum

This plant helps humidify the air and saturates it with purified water vapor. It actively absorbs xylene and toluene and converts them to compounds that don’t harm humans.

Gerbera jemsonii

This brightly colored flowering plant effectively removes trichloroethylene, formaldehyde and benzene from the air. It loves heat and sunshine.


The plant effectively cleans the air of formaldehyde and benzene, and Scindapsus tolerates shade. But this is a poisonous plant, so it should be kept away from children and animals.


This Chinese evergreen is an indoor plant that effectively cleans air of toluene and benzene. It grows in low light and likes moist air. But be careful. Its sap and berries are poisonous.

Bamboo palm

This plant filters benzene, xylene and toluene from air. It is best placed near furniture that is coated with paint and its harmful compounds.

The plant’s rich foliage and small white flowers actively fights benzene, formaldehyde, carbon monoxide, and xylene. Another reason to own this plant is safe for children and animals.

Are houseplants good for oxygen?

Plants that clean air absorb carbon dioxide produce oxygen, there's no doubt about that — but how many houseplants does it take to get noticeably more oxygen in the air? Humans consume about 550 liters of oxygen per day. Various factors influence how much oxygen a plant produces, including its size and the light on its leaves. It has been calculated that 22 liters of oxygen will be released while the plant's mass increases by 150 grams — and to get 550 liters per day, the growth must be 3.75 kilograms per day. 

It has been said that the quality of oxygen is higher in green spaces - but it doesn't make sense. Oxygen is just a molecule of two atoms, and it can't be low or high quality. In addition, plants not only do photosynthesis, but they also breathe - that is, they absorb carbon dioxide and produce oxygen. It has been shown that the amount of oxygen that plants add to the room atmosphere is negligible compared to the respiratory needs of humans.

Also, some houseplants can be toxic to humans and/or pets. Be sure to keep such plants out of reach of children and your parrots, dogs, and cats.

If you do not have enough patience or time to care for plants,there is an alternative. You can invest some money and buy an air purifier to improve the air quality in a room. Despite the cost, it should be much cheaper than paying the cost of medical bills due to poor air quality. 

Unlike the air purifiers that many manufacturers offer today, there are air purification systems that are fundamentally different from systems, whose basic principle of work is the  low-efficiency air filtration. To learn more about high efficiency air purification systems, please read our blog.
