16 Houseplants You Can Use as Air Purifiers

Updated 19th April 2020

Here are 16 plants that could clean your air for just the price of a few drops of water each day.

First lets check some of the evidence behind the claim that plants can purify your household air:

1. NASA Research

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

Here are the results of the NASA research study:

  Common name Scientific name Score
1 Areca palm Chrysalidocarpus lutescens 8.5
2 Lady palm Rhapis excelsa 8.5
3 Bamboo palm Chamaedorea seifrizii 8.4
4 Rubber plant Ficus robusta 8.0
5 Dracaena “Janet Craig” Dracaena deremensis “Janet Craig” 7.8
6 English ivy Hedera helix 7.8
7 Dwarf date palm Phoenix roebelinii 7.8
8 Ficus Alii Ficus macleilandii “Alii” 7.7
9 Boston fern Nephrolepis exalta “Bostoniensis” 7.5
10 Peace lily Spathiphyllum sp. 7.5

2. Interior Plants: Their Influence on Airborne Microbes inside Energy-efficient Buildings

In another study made in 1996, a bedroom with no plants had 50% more colonies of airborne microbes than a room which contained houseplants.

3. Foliage Plants For Indoor Removal of The Primary Combustion Gases Carbon Monoxide and Nitrogen Dioxide

During a laboratory experiment in 1985, Dr. Wolverton PHD compared the removal of carbon monoxide and nitrogen dioxide using a sealed chamber of spider plants.

4. Dr Wolverton – Formaldehyde removal experiment

In another laboratory study by Dr. Wolverton PHD, he compared a number of house plants at removing formaldehyde from a sealed chamber. Formaldehyde is a common household toxin that is released from a variety of household items.

With reference to the experiments of Dr Wolverton and the NASA experiments, I have compiled a list of 15 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.

The Areca palm tree is the very best air purifying plant according to the ratings from NASA’s research and has the 8th highest removal rate for Formaldehyde according to Dr Wolverton’s data. This house plant was referred to as “the most effective air humidifier” by MetaEfficient.com. The Areca has the ability to  maintain your office or home moist throughout dry periods as well as continually removing chemical toxins from your air. In the course of 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

This house plant – Lady palm (or Rhapis excelsa) achieved exactly 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 the majority sorts of 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.

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 present in the air. Bacteria within the rubber plants leaves break up the toxins and also feast on them. The procedure subsequently emits clean air in to the surrounding environment. Since the plant grows, these microorganisms increase.

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

6. Janet Craig – Dracaena

13. Chrysanthemum

Chrysanthemum

Aster Seeds 30Pcs Chrysanthemum Annual Outdoor Flower Garden Seeds Callistephus Chinensis Pink (Pink)
  • 🌺our China Aster seeds will begin germinating in as little as 7 to 10 days after sowing. The plants will mature to a height of roughly 12 to 36 inches tall and can be spaced about 12 to 18 inches apart.
  • 🌺China Asters make a wonderful cut flower and can be seen in many floral arrangements and bouquets as well.
  • 🌺hey will also attract an array of beneficial insects to the garden, such as butterflies, bumblebees, hummingbirds and ladybugs.
  • 🌺China Aster seeds will grow best in an area that consists of full sunlight to light shade.
  • 🌺To increase drainage, we recommend adding a light compost to areas containing hard, compact soil. Provide moisture when the soil becomes dry, until germination occurs.

This particularly attractive house plant was shown to be effective at removing the VOC compound – benzene which has been 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.

  1. Thanks for the links James.. i will work on getting a set of plants you can eat and also use a purifiers.

    Great comment!

  2. Nice job, too bad all the commenters are too lazy to do any additional research regarding pets, etc.. You can’t put everything in one article, but this is a good start.

  3. wow.. guess besides bamboo charcoal, there are many other plants can be used as home air purifiers too

  4. Is it healthy to have plant in your room where you sleep. I have plants in my room where i spend night to sleep, three big palm, and a date palm, a Tamarind, and Royal Poincian *flamboyant tree*. sometimes i have problem to breath, or bad breath , i put door open of my room for more fresh air!

  5. I sleep with 7 plants in my bedroom! I see no problem if the plants are health. It would also depend on what plants you have chosen.

  6. A word of caution about the ‘spider plant’ They are not necessarily pet friendly. There are a few types out there that people refer to as “Spider Plant”. The spider plant actually produces a chemical that works similar to an opiate to a pet. In low doses this may not be a problem, but large doses or extended munching can cause problems.

    With any plant accessible to your pets, check the SPCA website and/or consult a vet. Then, watch your pet to see if they leave it alone. I manage to keep some of these plants away from my pets through the use of red pepper sprinkled around the containers.

  7. I have some kind of plants in my bedroom. i have 3 big palm’s in pot, but i dont know name, the seed come for spain. I don’t know if its wrong to have many plant in my bedroom! In lifingroom we have a Cycas revoluta and banana tree, i sleep in my room under 3 big palms, have in same pot a Tamarind tree. Have a Royal poinciana, and a canary date palm, and now i have coconut palm.

  8. This is a wonderful article. I’m going to go out in the garden and see which of these plants can come inside.

  9. Germaphobe? Keep it properly watered and you will not have a fungal issue. Those bacterias will not harm you. They are necessary and beneficial.

  10. duh ok are you not getting that teh plants are purifying, you should not be getting mold in plants-unless overwatering. Also be aware that some level of exposure to bacteria is good for you!!!!!How did our ancestor survive.

  11. Yes some of these plants are poisonous to pets and children. But for those of you who are concerned about pets…they will not eat poisonous plants they have a natural instinct to eat only things that are good for them. Children on the other hand eat anything because that is part of their learing process…I would keep all plants out of their reach.

  12. I have raised 3 children and have had 8 grandchildren around my gazillion house plants and no one has ever eaten one. And true, animals are smart enough to know better.

  13. House plants can be great, better yet are bio-filters which use microbes tuned to eat just about any toxin.(very expensive). Okay plants for purifying you air… there are major issues here. 1) humidity , if the humidity in your house is over 50% you are in trouble and will grow mold. 2) because the plants need moisture and have a food source for molds, you will have molds at least growing in the soil. If you have asthma this NOT a good idea as mold is the number one trigger for asthma attacks (this is a medical fact).
    If you want good quality air.. keep the humidity in your house between 40 to 50% RH in the summer or 30 to 40% in the winter. The use standalone HEPA air cleaners, with 15Lbs or more of high-end blend activated carbon. That is all you need.. if you highly immune compromised, then you may consider germicidal UVc lamps.. But few need these and the must be used with a HEPA 99.97% at 0.3 microns) or ULPA filter (99.9995% at 0.3 microns).

    Then to do a good job you need to do 6 to 8 air exchanges per hour (this is environmentally dependent, for example a hospital OR room has 40 per hour), for home applications 6 to 8 is good especially if you have asthma, copd etc..

    Stay away from gimmick air cleaners. Ionizers typically produce ozone and that is NOT good. They are typically used with electronic air cleaners to improve their performance. Stay with HEPA as it will significantly our perform any electronic air cleaner. Stay anyway from any air cleaner that uses an oxidization process. The fact are the do incomplete oxidation and their produce more toxins than the remove. It is like a pill the doctors give you.. it made treat the symptoms but give you a heart attach in the process.

    I recently read so marketing on an air cleaner that uses a super HEPA (there is no such thing, after HEPA comes ULPA), The claim is that their HEPA captures a 100:1 more than most HEPA.
    They get a like creative here, their assumption is that other HEPA filters only capture partials down to 0.3 microns and nothing else and theirs capture down to .003 microns so therefore a 100 time better), that is false and deliberately misleading marketing. The 99.97% capture at 0.3 micron`s and industry standard test, it is the minimum standard which must be met to be called a HEPA filter and each filter must be individually tested to ensure it meets that standard. HEPA filter, filter out particles well below .3 microns.

    So stay with HEPA period! if you want a suggestion on a good one.. Well Austin Air is great.. it is easy for me to say that ans the USA department of defense test over 100 air cleaners. Only 4 of the 100 did the job and Austin Air was the most cost effective. So far in its price class and cost performance.. I have not yet seen a better one. However, Aller Air is also a very good one, A close copy of Austin Air, but here you can customize carbon blends which is important for those with MCS.
