Studies from NASA and other researchers have proven that plants help purify the air in your home. They do this through a  process called photosynthesis and respiration by taking in carbon dioxide, carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), volatile organic compounds (VOCs), and other toxins and then converting them into oxygen.

The plants I list below are considered to be natural air filters because they can purify air through absorption, dilution, precipitation, and filtration (Kim et al., 2018; Lee, Hadibarata, and Yuniarto 2020). This is also known by the term, “Phytoremediation”, which describes the various techniques by which they clear the environment of pollutants (Pilon-Smits 2005).

They can also reduce airborne viruses like Covid and other harmful microbes such as toxic mold in the environment.

Now, let’s go over the details of each of these plants I listed above so you can find the best ones for your home or office.

Areca Palm

The Areca Palm plant is great for cleaning indoor air for several reasons.

It is very efficient at removing carbon dioxide from the air and replacing it with oxygen. This is important because carbon dioxide levels can build up indoors, especially if there are a lot of people in a space.

They are one of the best plants for removing formaldehyde from the air because they thrive in high indoor temperatures (greater than 60 degrees Fahrenheit).

The Areca Palm plant is also known for its ability to reduce stress and promote relaxation. This can be a great benefit in an indoor environment where people may be under a lot of stress.

Spider Plant (Chlorophytum comosum)

Spider plants help remove benzene, formaldehyde, and xylene from the air, according to NASA studies. These chemicals are found in tobacco smoke, car exhaust, and other sources of pollution.

This common tropical houseplant is native to Africa and Asia. The spider plant gets its name from its long stems that look like spider legs when they’re hanging down from their pots. The spider plant is also easy to grow indoors and tolerates low-light conditions well.

This makes it a great choice for beginners who don’t have much experience with growing houseplants. Just make sure there’s enough room for this plant; it can grow very large.

Money Plant

The money plant is a powerful natural cleaner that can be used to help purify the air in your home or office. It has been used by Chinese people for centuries as an air-purifier and it’s one of the most popular houseplants they grow.

Money plants are very easy to grow indoors, and they’ll thrive in any medium-light environment. They’re also low maintenance – they don’t need much water or fertilizer, and they don’t need to be pruned or kept warm like other houseplants do.

Snake Plant

The snake plant can help remove formaldehyde, which is found in furniture and building materials. Formaldehyde is one of the most dangerous chemicals used in industry today and some people are sensitive to it.

The snake plant can also remove other toxins from your home like benzene and trichloroethylene (TCE), which are both found in paint, cleaning products and even vehicle exhaust fumes.

The Snake Plant is also known as Mother-in-Law’s Tongue or Lady’s Slipper. It is native to India and grows in cold climates where it can be found growing along riversides, streams and ponds. It was brought to Europe in the 18th century by French aristocrat Madame de Pompadour who grew them in her gardens.

Rubber Plant

Rubber plants are a beautiful, easy-to-grow houseplant that can help clean indoor air.

The rubber plant, or Ficus elastica, is a tropical fig tree native to South and Southeast Asia. It grows up to 60 feet tall and produces glossy green leaves that are leathery and thick with a large surface area for absorbing pollutants from the air. The tree also produces a sticky latex sap that’s secreted by its leaves when they’re cut or damaged.

The rubber plant has been shown to help clean indoor air by removing toxins like benzene, formaldehyde and trichloroethylene (TCE). These chemicals are common in many household products like cleaning supplies, dryer sheets and permanent markers — so having one or two plants around can help neutralize their presence in your home.

Pothos (Devil’s Ivy)

Peace Lily

Peace lilies are one of the most popular houseplants because they’re so easy to grow and maintain.

A study from NASA found that they can remove formaldehyde from indoor air. Formaldehyde is a common indoor air pollutant resulting from many household materials and products, including particleboard furniture, carpets and wall paneling. The Peace Lily has been shown to absorb formaldehyde fumes from the air.

Peace Lilies are also known to filter out benzene, trichloroethylene and xylene. These three chemicals are often found in cleaning products such as paint thinners, lacquers and adhesives, as well as in some household paints.

English Ivy (Hedera helix)

English ivy (Hedera helix) is a common houseplant that is also used as a ground cover in gardens.

English ivy is an evergreen climbing vine that grows vigorously outdoors as well as indoors, so it’s a good choice if you want something that can climb up walls or trellises without much effort on your part! They help remove formaldehyde from the air in addition to other harmful chemicals like xylene and trichloroethylene.

They are also easy to care for, and they are tolerant of low light and low humidity.

Gerbera Daisy

According to the NASA study, within 24 hours, the gerbera daisy had removed half of the airborne formaldehyde, 67% of the benzene and 35% of the trichloroethylene from the indoor air. That is very impressive!

Gerber daisies or gerberas are great for indoor growing indoors. They will liven up your home with their brightly colored flowers in shades of pink, red, yellow, orange, and lavender.

This plant is a member of the Asteraceae family, which includes many other popular household plants, such as daisies and asters. The Gerber Daisy (Gerbera jamesonii) is native to South Africa and has been hybridized for more than 100 years.

Broad lady palm

Broad lady palm, or Rhapis excelsa, is a species of palm that originates from Asia. Studies have shown that Broad lady palm is effective at removing formaldehyde, nitrogen oxides, and benzene from the air.

Additionally, the plant has been shown to increase humidity levels, which can help to ease respiratory problems such as dry coughs and sore throats. Broad lady palm is a low-maintenance plant that does not require direct sunlight or frequent watering. As a result, it is an ideal choice for those looking for a easy-to-care-for plant that can improve indoor air quality.

Dwarf Date Palm (Phoenix roebelenii)
