16 Houseplants You Can Use as Air Purifiers

Last updated May 24, 2023

Danny as been writing about air purifiers for 10+ years. He is a major fan of home technology, which makes him the perfect person to test and evaluate products for HouseFresh

When I first wrote up this research paper, there was general agreement that it was correct that houseplants plants in the home can help to clean the air. But since that publication, several public responses from prominent scientists have rejected the idea, including on Therefore, we share this list of plants but recommend you not buy them if your only plan is to clean your air.

We think plants have many benefits, so don’t let this put you off owning and looking after plants.

If you are serious about cleaning the air in your home, then be sure to check out the specific guides we have written with our recommended units based on our in-house testing and analysis:

The Best Air Purifiers in 2023

A Note About Pets:

As noted by several readers, many of the plants on this list can also be poisonous to dogs and other pets. Be sure to check for any potential poison or allergies from the plants for your animal, and try to put plants in locations that pets can not reach.

If you do have pets, check out the recently updated list of our recommended air purifiers s for pets, as these, in combination with a combination of the 15 plants on this list, can allow pet owners to live without the fear of allergic reactions.

If you want to clean your home’s air, I suggest a cheap HEPA air purifier; we recently reviewed the Levoit 300 and Levoit PUR131.

1. NASA Research

A NASA research document concluded that “house plants can purify and rejuvenate air within our houses and workplaces, safeguarding us from any side effects connected with prevalent toxins such as formaldehyde, ammonia and benzene.”

Here are the results of the NASA research study:

16 Air Purifier Plants

Concerning Dr. Wolverton’s and NASA’s experiments, I have compiled a list of 16 house plants that provide the greatest level of air purification.

1. Areca Palm Tree

Areca Palm Tree
The ultimate “plant air purifier,” according to NASA

Costa Farms Areca Butterfly Palm Tree, Live Indoor Plant, 3 to 4-Feet Tall, Ships in Grow Pot, Fresh From Our Farm, Excellent Gift
  • Do not recommend shipping to states currently experiencing extreme cold weather/temperatures.
  • I can adapt to full sun or light shade, but bright indirect sunlight is the best!
  • Place me on your patio to create a topical paradise!
  • I love regular watering's, keep me damp, but not muddy
  • We're unable to ship this item to: AK,AZ,CA,GU,HI

According to the ratings from NASA’s research, the Areca palm tree is the best air-purifying plant. According to Dr Wolverton’s data, it has the 8th highest removal rate for Formaldehyde. This house plant was referred to as “the most effective air humidifier” by The Areca can maintain your office or home moist throughout dry periods and continually remove chemical toxins from your air. During the winter season, it’s so effective at putting moisture back in the air that you could switch off your electric humidifiers!

2. Lady Palm

Lady Palm

American Plant Exchange Lady Palm Rhapis Excelsa Indoor/Outdoor Air Purifier Live Plant, 6" Pot
  • A graceful palm for gardens or a beautiful addition to an indoor space.
  • Adds an elegant and graceful tropical effect to any home.
  • Slow growing, bamboo-like clustering trunk pattern.
  • Wonderful in large pots and containers.
  • Nasa clean air study discovered Rhapis Excelsa to be one of the Best houseplants at cleansing the air of formaldehyde, ammonia, xylene and toluene.

This house plant – Lady palm (or Rhapis excelsa) achieved the same rating as the Areca Palm tree in NASA’s research. This adaptable house plant can be stored in dry or moist parts of the world ( between 20-100° Fahrenheit) and is particularly resistant to most plant insects.

The Lady Palm is not the most effective at removing Formaldehyde, so if this is a concern, then I would suggest you look at another plant.

The bamboo palm was the third most powerful plant at removing formaldehyde from the air. It ranked third in the NASA experiment, so it is a good all-rounder at keeping your room air clean. This house plant will grow best in moist but not wet soil and in direct sunlight. However, this palm will require much room to grow, so it might not be the best option if you want this plant to sit on your desk.

5. Rubber Plant

Rubber Plant

Burgundy Rubber Tree Plant - Ficus - an Old Favorite - 6" Pot
  • Easy to grow house plant
  • Great for the house, apartment, office or dorm
  • Provide bright, indirect or artificial light
  • Trim as needed
  • The plant you will receive is growing in a 6" pot

This rubber house plant (Ficus robusta) has been mentioned as one of the leading Twenty plants by doctors. B.C. “Bill” Wolverton’s “50 Houseplants That Purify Your Home Or Office.” This rubber house plant provides moisture, eliminates bio effluents, takes away volatile organic compounds as well as suppresses air-based microorganisms as soon as it’s put into a room

As time passes, this rubber plant will become much more skilled at eliminating toxic compounds in the air. Bacteria within the rubber plants leaves to break up the toxins and feast on them. The procedure subsequently emits clean air into the surrounding environment. Since the plant grows, these microorganisms increase.

This increased number of bacteria assists the rubber house plant in becoming progressively more effective at extracting further toxic compounds from the air.

6. Janet Craig – Dracaena

Janet Craig Dracaena

No products found.

The Dracaena (or Dracaena deremensis) places fifth on NASA’s ranking with a 7.8 score.  According to data, it can remove Formaldehyde at a rate of 1,328 micrograms per hour. It also removes Xylene at a rate of 154 micrograms per hour, according to

Recommended Placement in Home: These are especially effective in newly carpeted or newly furnished rooms where formaldehyde levels are at the highest.

Tips to keep this plant healthy:

  • Favors vibrant light, although not direct sunlight.
  • Water completely through early spring through the winter season and allow the plant’s soil to dry out in between watering

7. English Ivy

English Ivy

American Plant Exchange Easy Care English Ivy California Trailing Vine Live Plant, 6" Pot, Indoor/Outdoor Air Purifier
  • The English ivy plant is a classic, fan-shaped, Silver green ivy.
  • Makes a wonderful, bright light houseplant. It will grow long and lush, bringing a bit of the outdoors inside.

  • English ivy helps in reducing indoor air pollution and certain allergens from the house like molds and other fungus growth. It also removes airborne fecal matter from pets and formaldehyde from household cleaning products.

If your airflow in your area has stagnated and dried out, English ivy (also known as Hedera helix) may be the solution! talks about this effervescent house plant as “a solution for allergic reactions,” observing that sixty percent of air-based mold within the space was removed after just six hrs right after introducing English ivy.

People with allergies, asthma, or even wanting to inhale cleaner, more fresh air might be wise to give this English ivy plant a shot!

8. Date Palm Tree

Date Palm Tree

Although it does not position at the top of the purifying scale when compared to its three palm relatives, make no mistake: this Date palm house plant (also known as Phoenix roebelinii) remains an extremely efficient and stylish-looking method to both cheer up the design of an area and reduce the content level of volatile organic compounds floating all over the air.

The Date house plant is very effective at getting rid of formaldehyde and thus works great in combination with other purifier plants (it has the second-highest removal rate after the fern plant.)

Aloe vera was proven to be much more effective at eliminating formaldehyde at lesser concentrations when compared with Philodendrons. Aloe vera is likewise famous for being a healing plant acknowledged for its therapeutic qualities, giving it most of its nicknames.


The Aloe house plant was also used in the initial photography used for the Andrea plant air purifier – probably due to the plant’s purification properties.

12. Spider Plants

Spider Plants

The spider plant was used by Dr. Wolverton in his 1985 study that examined the plant’s removal of carbon monoxide and nitrogen dioxide. In a room with many spider plants, the amount of carbon monoxide and nitrogen dioxide dropped to near zero after only 24 hours.


13. Chrysanthemum


This beautiful house plant effectively removed the VOC compound – benzene is known to cause cancer.

Many tobacco products contain high levels of benzene, so it would be helpful to have one of these plants in a smoking household. However, no house plant can ever negate the effects of tobacco smoke.

Remember to be careful with Chrysanthemum as it is poisonous when ingested or with prolonged skin exposure.

14. Heart leaf philodendron

Heart leaf philodendron

The N.A.S.A. study showed that the Philodendron house plant was one of the best house plants for eliminating formaldehyde from the surrounding air, especially when working with higher concentrations.

15. Snake Plants or Mother of Law Tongue


Snake Plant, Mother-In-Law's Tongue - Sanseveria - 6" Pot/unique-from jmbamboo
  • 10-12'' inch live plant.Extremely hardy house plant, difficult to kill

  • In China, it was kept as a treasured houseplant because the Eight Gods bestowed their eight virtues on those who grew them
  • Will grow in dime light, water when dry
  • The plant you will receive is growing in a 6" pot

Snake house plants — these types of plants tend to be incredible growers and extremely tough. They’re excellent at eliminating most toxins and are quite happy to grow in areas where other plants may decline and perish ( say, a hot window ledge). Also, they are great bathrooms and darker area plants.

16. Sago Palm Air Purifier

Snake Plant, Mother-In-Law's Tongue - Sanseveria - 6" Pot/unique-from jmbamboo
  • 10-12'' inch live plant.Extremely hardy house plant, difficult to kill

  • Will grow in dime light, water when dry
  • The plant you will receive is growing in a 6" pot

There are many air-purifying palms on this list for a good reason, and the sago palm is a great plant for cleaning the air.

One Final Point:

Make sure to Maintain your house plants in good condition and make sure you have enough of them. The NASA research advised that there should be a six-inch plant for every 100 sq feet of interior living space.

  1. Pingback: “Got Birds?”
  2. I just wanted to know if any of these plants harm animals? I have two cats and a spider plant that i keep away from them because I was told to keep it away from them. If the spider plant is harmful,which plant is best for me?

  3. Ummm… And what, then, do we do about the molds and bacterias that live and breed in the moist soil in the planters?

  4. Hi there,
    I am Leland Smith,

    I was just wondering if marijuana plants would help purify the air. I don’t grow nor do I smoke this drug but it has caught my curiousity. Please let me know.

  5. My question is, I have had almost all of these plants and never had a problem with them until I moved from California to Texas, they all died within about 6 months after moving. I did nothing different to them other than move them from one state to another, could that of had something to do with it or could it of been the home I moved into. My mother has lived in the same house for at least 17 years and has never been able to keep a plant alive and she just as myself has never had aproblem with our plants. (Green Thumb as some may say)

  6. This information would be much more helpful if you also included which plants are poisonous for children, dogs, and cats. If you make revisions, please consider adding that info. Thanks!

  7. Thank you for this report. I had heard having plants indoors was a good way to remove toxins but did not know which ones.

  8. Thank you, I love this kind of an educational post. Glad to know I have some of the plants that you mention in my home & now have a better idea of the remaining ones I should buy.

  9. I found this list of plants to be very helpful. I love house plants and have many allready. Its good to know which ones are helping my home and to purify my air.. Thank you

  10. I watch your show every day. It is like taking a college coarse. I learn so much.

    Thanks so Much..
    Love your show
    Marilyn G…

  13. I am excited to hear about these plant air purifiers. I will tell all my friends and family! Thanks for the information

  14. everyone of these plants I have had or still have… I will now replace the ones I no longer have… I LOVE PLANTS

  15. I have had houseplants since I was a young girl. Then I’ve collected, grown and gave many away over the years. Still, several rooms of my home appear to be an indoor garden. I was pleased to read that my unknowing choices are actually very healthy ones, as I have at least one of the plants on your list in every room and all but one room has several plants listed! Thank you for sharing this information.

  16. For those worried about spider plants and cats… aunt has always kept a spider plant specifically for her cats to eat during the winter when they cannot get to grass here in Michigan. I, too, have cats that eat my spider plants. Neither of us have ever had a problem as a result.

  17. Am so happy to have info on houseplants, have very large aloe and others in my bedroom bay window. Now I know that they are good for me!!

  18. this so good i have four out of the plant and i was thinking of getting an air purifier now i see i don’t need it after all

  19. I’ve been raising plants for over 25 years. Spider plants are great they’re pet friendly, easy to maintain, easy to start new plants (no rooting needed, just gently break spider from plant and put into soil, water, and it will root and grow).

    Mother in law tongue is a tough plant to kill. I’ve had both cats and dogs and no issues with any plant.

    Ivy is nice and easy too…again I have not had problems with my cats and dogs.

  20. thank you so much for this page. i was so happy when i saw this at DR. OZ’s page at
    again, thanks so much, coz i dont get to go out that much now a days and im so in need of fresh air. so i guess buying the right type of plant for the house is now on top of my list.


    dont forget to follow me at

  21. thanks, very helpfull. I pretty well know about the dog and cat stuff with plants, how about bunnys? we have two house bunnys and I would hate to poision them out of ignorence. they do there best to eat my plants now when leaves hit the floor or they droop enough for them to reach.

  22. For Dorothy de la Rosa,
    You said your plants “all died within about 6 months after moving.” ” My mother has lived in the same house for at least 17 years and has never been able to keep a plant alive and she just as myself has never had aproblem with our plants.”

    It sounds very likely that your house is subject to Geopathic stress. This causes plants to die, but it’s also very harmful to humans so it’s important you get it checked out or move house. It is the main cause of Sudden Infant Death Syndrome and if you sleep in a particularly bad place then your could get cancer.

    I have had this problem in several houses I’ve lived in.

    See this page for more information.
    I bought a Raditech from the Dulwich Health Society and it works wonders at neutralising an otherwise stressed place.
