Houseplants have become popular in recent years, but their effectiveness in purifying air remains uncertain. A 2019 review published in the Journal of Exposure Science and Environmental Epidemiology found that potted plants do not significantly improve indoor air quality. Drexel University researchers Bryan Cummings and Michael Waring examined past studies to determine if houseplants can effectively reduce indoor air pollution.
An influential NASA study from 1989 found that indoor plants could remove formaldehyde and other volatile organic compounds (VOCs) from the air, but the study was unrealistic for real-world use. Some scientists believe that houseplants are effective natural air purifiers, with bigger and leafier plants being more beneficial. However, the jury is still out on whether houseplants reduce indoor air pollution.
The reality is that the soil and foliage, possibly the pots if using clay or clay, do not truly “clean” or purify the air. While plants can be beneficial, the evidence does not show that they are an effective tool to reduce air pollution. Plants do clear toxic compounds from the air, but living rooms and offices are not small, sealed chambers in labs.
While a single spider plant won’t purify the air, a green wall covered in plants might help. Houseplants that clean the air include Philodendrons, Aglaonema, Aloe Vera, Dracaena Spider Plant Peace Lily, and Philodendrons Aglaonema, Aloe Vera, Dracaena Spider Plant Peace Lily.
📹 Can Houseplants Improve Air Quality?
We all have that coworker who insists that the houseplants on their desks are improving the office air quality, but is there any truth …
Do snake plants actually purify air?
Snake plants are air-purifying plants that release oxygen and moisture into the air, thereby reducing allergens and the impact of dander and dust. The plants are engaged in continuous air purification, with the highest oxygen production occurring at night.
Which plants gives 24 hours oxygen?
The peepal tree, also known as the bo or bodhi tree, is a tree native to India, Myanmar, and Sri Lanka, and now found throughout Southeast Asia. It grows up to 15 meters tall and has grey bark on its branches. The tree has pinnate leaves with seven leaflets arranged alternately on each side, and each leaflet has five double-serrated edges. The leaves are large, up to 30 cm across, and the flowers are small and yellow-green, with a five-lobed corolla. The fruit is a capsule with many seeds inside. In summary, the peepal tree is a unique plant that provides oxygen for 24 hours.
Are house plants bad for the environment?
Houseplants play a crucial role in combating climate change by absorbing carbon dioxide during photosynthesis. While their impact on global carbon dioxide levels may be small, every little bit helps. Studies suggest that indoor plants may have a greater carbon sequestration potential, with a single large plant potentially sequestering up to 1. 3 kilograms of carbon dioxide per year. Plants also help regulate indoor temperatures by absorbing heat and providing shade, reducing the need for air conditioning in summer and heating in winter.
Additionally, plants improve insulation properties by reducing heat loss through windows and walls, further reducing heating and cooling needs, positively impacting the environment and energy costs. Overall, houseplants play a significant role in reducing greenhouse gas emissions and promoting sustainable living.
Which indoor plant purifies the air the most?
Bamboo palms are highly effective in purifying air by removing chemicals from paints and carpets. They require a large space to grow, but their ability to filter air is a significant advantage. Chrysanthemums, also known as ‘Mums’, provide a vibrant display and are also beneficial for air purification. They remove chemicals from paints and glues. To maintain their blooming, place them in a bright room with direct sunlight.
English ivy, a houseplant, not only cleanses air but also reduces airborne fecal matter, which can be harmful if left untreated and spread diseases. These plants are ideal for the bathroom to maintain a healthy environment.
Do houseplants reduce dust?
Plants play a crucial role in maintaining home humidity levels by emitting water particles during transpiration, which naturally lower dust levels. These water particles combine with dust particles, causing them to fall from the air and towards the floor. Additionally, plants produce negative ions, similar to static or magnetism, which physically pull dust particles from the air and onto their leaves.
Spider plants, commonly found in paper bags, plywood furniture, and synthetic fabrics, help remove formaldehyde and carbon monoxide from the air. These plants thrive in any soil and require occasional watering.

By choosing plants from the list, you can naturally remove sources of indoor air pollution like formaldehyde, trichloroethylene, benzene, and xylene, and replace them with CO2 for a happier and healthier lifestyle. Whether you’re a beginner or an experienced plant owner, houseplants are a simple solution to bring the outdoors into your home year-round.
Do plants make the air dirty yes or no?
NASA research scientists have discovered that plants can help combat sick building syndrome by removing pollutants like formaldehyde, benzene, and trichloroethylene through photosynthesis and transpiration. They studied about a dozen popular ornamental plants to determine their effectiveness in removing these pollutants. Some plants will be launched into space as part of the biological life support system aboard future orbiting space stations.
One of the best plants for indoor air quality is the Spider Plant (Chlorophytum comosum), known for its ability to remove formaldehyde, xylene, and toluene. Spider plants thrive in indirect sunlight and tolerate a range of temperatures, making them easy to care for and effective in improving indoor air quality.

How many houseplants do you need to clean the air?
NASA recommends the planting of one plant for every 100 square feet of surface area, which equates to a density of approximately nine plants per 100 square feet. Two square meters are recommended for residences with an area of 1800 square feet, which is equivalent to 167 square meters. For residences of greater size, the recommendation is to include 15 to 18 houseplants. The precise number is contingent upon the specific plant species and its efficacy in detoxifying the environment. The majority of plants are purchased for use in bedrooms, living rooms, home offices, and children’s playrooms.
What plant is NASA recommend for air purifiers?
The Snake Plant, also known as the Mother-In-Law’s Tongue, is a unique plant that produces nighttime oxygen and can purify air by removing benzene, formaldehyde, trichloroethylene, xylene, and toluene. It produces fragrant flowers and effectively removes these pollutants from the air. The plant grows best in shady areas with moist soil. However, it can be toxic if eaten by children or pets. To care for the plant, maintain a constant temperature, allow it direct sunlight, and water it frequently with well-drained soil.
Do houseplants really purify the air?
Indoor plants can help clean the air and increase oxygen levels, but they should not replace air purifiers. They can boost creativity, productivity, concentration, memory, and reduce stress. A variety of plants is most beneficial. However, pets like cats and dogs may be impacted by some plants, so it’s important to choose pet-safe and allergy-safe options. Check the ASPCA Toxic and Non-Toxic Plants page for information on toxic plants for animals.
📹 How Well Do Houseplants Really Clean & Purify The Air? / Joy Us Garden
My conclusion is at the end of this video & the post but 1st I want to share a few thoughts with you. There’s a complex process …
Hi, Nell. Thank you for this article. Whether or not my house plants clean the air – what the heck. I love them, because they are beautiful and because they make me happy. I don’t buy them to aircondition my home. I enjoy them especially during the long winter season here in Germany, when the city is gray, when all the trees and shrubs have gone dormant. Then my house plants remind me of green times, of spring and summer. And those are my seasons. Ok, Nell, take care. I go out in the garden now and make my world a more beautiful place. See ya soon. 😉
Well, I declare! You are the best scientist for this job. You did the research. Now, may I suggest the following article experiment. 1 small room in your house. Use air quality control meter. Take reading. Take plants out. Take reading. Use room as normal. Let time pass. etc. Put your plants back in the room. Take reading. etc. You get the idea. Initially, all scientist are taught that they must control everything so their work excludes as many false posibilities as possible. See what happens; you scientist!
Well researched Nell. As for the language in scholarly works they use the language they do because it is a way to cover themselves. Good researchers know that with improvements in technology you may find new things that were not found in your study. That is why in scholarly works they always mention that further research may be needed. The word choice such as ‘may cause’ is strong in the academic field. Academic language differs somewhat from everyday language. Thank you for making this article. I bought house plants in hopes of improving my home’s air quality, I’m not sure if it did or not but the plants sure made me happy.
There’s a Study in France done by a University for about 5 years in a real world situation. It’s called Phyt’Air. It says the same as you. Plants do clean the air but it’s not that significant. They found that the best results are from soil/micro-organisms/plant association. They also found that potting soil with only microbes performs better than plants alone. In fact plant has little to do with depollution, it’s mostly the micro-organisms. Plants then reabsorb the mineralized components.To stimulate microbial population, they give off some of the sugars they produce through photosynthesis because they want those chemicals broken down by someone to feed themselves.
Interesting topic. I really thought they did a great job cleaning the air. What I have noticed though is the smell. For some reason the air indoors has a pleasant smell of freshness to me. Especially in homes that have an extensive collection of house plants (eg., like a mini forest), it also feels much cooler than homes without!
Hi Nell, I agree with you on some of the points you brought up. I think they actually offer so much more than cleaning the air such as what you said about feeding the soul. I believe the study for the conditions they tested but I agree, in our homes it’s an entirely different thing. So many variables. It sort of makes me think of humidity trays (in whatever form). They work good or great depending on the environment and so many variables. It also makes me think of vitamins and if those work and how well. I read an article a while back where they mentioned that most doctors won’t recommend them because of lack of proof but most doctors take them. Science/proof isn’t everything. p.s. If I’m ever living in space, I definitely want a plant. ;D
If you put a human being in a sealed room with no air flow, they will eventually use up all the oxygen and die. However if you add 6 snake plants to the room, then they will process enough carbon dioxide to allow the human to live indefinitely. So I think if you have enough plants, they do clean the air.
