Best Air Purifying Plants for your Home

Top air-filtering indoor plants according to NASA

Did you know that the air that we breathe inside our homes has pollutants that affect directly our health?

Nowadays, buildings are filled with modern furnishings and highly technological equipment that emit hundreds of Volatile Organic Compounds (VOCs). VOCs are a large group of chemicals that vaporize and become gases at normal room temperature. They are found in many products we use to build and maintain our homes such as paints, varnishes, aerosol sprays, cleansers, furniture, and so on. These materials release chemical gases into the indoor air that we breathe, which affect directly our health. Some health problems may include eye, nose, and throat irritation, headaches, and damage to the central nervous system. If you want to know more details about VOCs, you can find them here: Volatile Organic Compounds' Impact on Indoor Air Quality.

Now that you know that indoor air pollution is a real threat to human health, how can the problem be solved?

According to NASA's Clean Air study, one effective way to reduce the levels of air pollutants inside homes is the use of specific indoor plants. NASA's researchers suggest one plant per approximately 9.2 square meters to efficiently clear the indoor air of your home. You can locate these plants most likely in your bedroom, living room, and other rooms like your home office or your children's playroom.

Best Air Purifying Indoor Plants

English Ivy

English ivy is a versatile plant that can be grown in hanging baskets, at the base of other houseplants, or in pots of their own. They grow best in direct sunlight and need to be watered once the soil dries out.

According to NASA's study, English ivy is the most effective houseplant for cleaning benzene from the air, removing 89.8% of benzene over 24 hours.

Spider Plant

Spider plants are extremely easy to grow since they survive with inconsistent watering. Studies show that spider plant are effective in absorbing chemicals such as formaldehyde, xylene, benzene, and carbon dioxide in homes and offices.

Peace Lily

Peace Lily is a flower and aesthetically pleasing plant. Additionally, it can benefit your health over time. According to the study Clean Skin From Within, published in 2022, peace lilies help to remove carbon dioxide and volatile organic compounds (VOCs) from the air. Peace lilies can live for years and constantly bloom white flowers.

Moreover, the peace lily helps eliminate mold spores in the air. It is beneficial, especially to people who are sensitive to these mold spores. For instance, exposure to mold spores leads to eye irritation, coughing, sneezing, and throat and skin irritation.

Another benefit of the peace lily is that it is a plant easy and practical to take care of and it doesn't need much light. Therefore, they are perfect for shady spaces and wintertime.


Snake Plants

Long known as “mother-in-law’s tongues,” the snake plant, features tall leaves that grow vertically. They are extremely low-maintenance. The plants only need to be watered when the soil is dry, and grow in any kind of light.

The benefits of snake plants are various. To cite some, they are great oxygen-producing houseplants and they absorb air pollutants such as carbon dioxide, benzene, formaldehyde, xylene, and toluene. In summary, snake plants are great to improve indoor air quality.


Also known as devil’s ivy or golden pothos, they have vibrant heart-shaped leaves. They are easy to maintain and they grow without sunlight. Research shows that these plants can lower indoor ozone levels, which can make it easier to breathe and reduce your risk for respiratory ailments, as well as remove VOCs from the air.

Gerbera daisy

A flower named after innocence, purity, and cheerfulness, the Gerbera daisies are one of the longest-lasting flowers. They also provide added health benefits by discharging oxygen and absorbing carbon dioxide and other airborne toxins at night.

According to NASA, in 24 hours, this flower removes half of the airborne formaldehyde, 67% of the benzene, and 35% of the trichloroethylene.

Other health benefits of indoor plants

Common Cold – As indoor plants increase humidity levels and decrease dust they can reduce cold-related sickness.

Drowsiness – Extra carbon dioxide can cause drowsiness levels to increase, but during photosynthesis, plants remove carbon dioxide from the air allowing you to feel more alert.

Stress – Plants are known to increase the feeling of well-being, helping you feel calmer and have a better outlook on life.

Headache – Because of the air-purifying properties of plants and the oxygen they create, you are less likely to breathe in musty stale air that contributes to headaches, allergies, and sinus trouble.

Dry Skin – Plants are a natural humidifier, which increases moisture levels in the air keeping your home less dry and your skin moister.

Insomnia – Because plants give off oxygen, they can help you have a great night’s sleep. Plants like gerbera daisies release oxygen at night, so keep them by your bed for optimal oxygen levels while you get well-rested.
