Many people think that houseplants can make the air in our homes clean and fresh. But, the truth is, their air-cleaning power is quite small1. They can’t filter out many harmful substances like volatile organic compounds (VOCs) well.
To really clean the air, you’d need a huge number of plants, up to 1,000 per square meter1. That’s way too many for any home. Even with a few plants, they only take out tiny bits of pollutants. They don’t do much to change the air quality.
Houseplants do make our homes look nice, though. But, they’re not a good way to clean the air we breathe.
Key Takeaways
- The idea that houseplants can effectively clean indoor air is a myth.
- Plants can only remove small amounts of pollutants and their ability to absorb carbon dioxide and produce oxygen is not enough to improve air quality significantly.
- To effectively filter out VOCs, you would need 10-1,000 plants per square meter, which is not practical for most homes.
- While plants can be visually appealing, they are not a reliable solution for purifying indoor air.
- Other methods, such as air purifiers and proper ventilation, are more effective for improving indoor air quality.
The Myth of Air-Purifying Plants: What the Research Reveals
The idea that houseplants can clean indoor air has been debated for a long time. Many believe they can make a big difference, but the truth is more complex2. Let’s dive into what research really says about plants and air quality.
Research Findings on Plant’s Air Purification Capabilities
The famous NASA study on plants and air quality was done in small, sealed spaces. These conditions don’t match real-life indoor settings2. The study showed some plants could remove pollutants like benzene and trichloroethylene. But in real homes and offices, the effectiveness was much lower, removing 50 to 90% of benzene and 9 to 23% of trichloroethylene2.
The study also found that plants aren’t the only ones cleaning the air. The soil and plant system together are key to air purification2. It didn’t suggest using one plant for every 100 square feet for clean air. Instead, it recommended 10 to 1,000 plants per square meter for better air quality, similar to office air systems2.
Limitations of Plants in Removing Indoor Air Pollutants
Plants can help make indoor air better, but they have limits3. Research shows they remove pollutants at best by 0.9–9%3. Only a few plants, like peace lilies and chrysanthemums, are proven to cut down on certain pollutants3.
Plants also have mental health benefits, like reducing stress and making us feel more at ease3. But they shouldn’t be the only answer for clean air. Using air purifiers and good ventilation is key for clean air4.
In conclusion, the idea that plants can purify air is often overstated. While they do offer some benefits, their role is limited. They shouldn’t be the main way to improve indoor air quality. Knowing the real benefits and limits of plants helps us create better indoor spaces234.
Understanding Indoor Air Pollution and Its Effects
Houseplants are often praised for improving indoor air quality, but the truth is more nuanced. Indoor air can be 2 to 5 times more polluted than outdoor air, says the Environmental Protection Agency5. This pollution comes from many sources, like cleaning products, furniture, and building materials, as well as harmful gases and particles5.
These pollutants can cause health problems, such as headaches, nausea, and irritation of the eyes, nose, and throat5. They can even harm the kidneys, liver, and brain. The World Health Organization says that indoor air pollution leads to about 4.2 million deaths each year6. Secondhand smoke and pollution from cooking stoves also cause thousands of deaths annually, mostly among women and children6.
Common Indoor Air Pollutants and Their Sources
Here are some common indoor air pollutants and where they come from:
- Volatile Organic Compounds (VOCs) – from cleaning products, furniture, and building materials5
- Particulate Matter – from cooking, smoking, and dust
- Carbon Monoxide – from faulty fuel-burning devices
- Radon – a radioactive gas that comes from the ground
Indoor plants can help clean the air, but they’re not a full solution6. To match the NASA study’s air-cleaning results, a home would need 680 plants5. Using air purifiers and good ventilation is usually better for clean air than just plants7.
Some plants can be harmful to pets, like spider plants and peace lilies5. So, think carefully about which plants to have at home if you have pets.
“HEPA filters remove 99.97% of airborne particles that are 0.3 microns or larger from the air that passes through it.”6
As technology gets better, air purifiers are getting more effective at cleaning the air6. New air purifiers use advanced sensors and technology to remove tiny pollutants6. When picking an air purifier, look for a high CADR rating to make sure it cleans the air well6.
In conclusion, while plants help with air quality, they’re not enough to solve indoor pollution. Using air purifiers, good ventilation, and low-emitting materials is a better way to keep indoor air clean.
Is There a Plant That Can Clean the Air?
Some air purifying houseplants can remove certain pollutants from the air, but they don’t do it all by themselves8. You’d need a huge number of plants to see a real difference in air quality9.
Houseplants like the money plant, spider plant, and snake plant can take out volatile organic compounds (VOCs) and other bad stuff810. But, they can’t beat the effectiveness of air purifiers or good ventilation9.
Still, indoor plants bring big benefits to your home. NASA’s Bill Wolverton found in 1989 that they’re a budget-friendly way to fight indoor pollution8. These plants work like nature’s air filters, making the air cleaner through photosynthesis and taking in pollutants8.
They’re great for places where the air isn’t good, acting as personal air cleaners8. These plants also make people feel better, lowering stress and boosting creativity8.
For your air-purifying plants to work well, pay attention to their needs. Each plant likes different light, so pick one that fits your room’s light8. Knowing what each plant needs helps it clean the air better8.
Keeping the right humidity helps air-purifying plants do their job8. Water them right to keep them healthy and effective8. The right temperature lets these plants clean the air well8.
Use pots with holes to stop waterlogging and repot often to keep the soil fresh8. While plants help, they’re not a full replacement for air purifiers or good ventilation9. For the best air quality, use plants, purifiers, and good airflow together8109.
Proven Methods for Improving Indoor Air Quality
Houseplants can make your home look nice and feel better, but they don’t clean the air well11. To really clean the air, you’d need a huge number of plants, which isn’t practical11. Also, most studies on plants and air quality are done in small, sealed spaces that don’t match real life11.
For better air quality, using air purifiers and good ventilation at home works best11. Air purifiers clean the air by catching bad particles and pollutants12. Experts say one air purifier can clean the air better than thousands of plants11. Opening windows can also clean the air, but not when you have allergies11.
The Effectiveness of Air Purifiers and Proper Ventilation
Good air flow and air purifiers are key for clean indoor air11. Studies say indoor air is often 2-5 times dirtier than outside air1213. Since we’re inside most of the time, this is a big concern12. To clean the air well, having a few big air-purifying plants per 100 square feet is best12.
Some plants like the Bamboo Palm and Spider Plant can take out harmful chemicals from the air12. But, they’re not as good as air purifiers at cleaning the air11. Also, some plants can cause allergies and asthma attacks if they’re not taken care of11.
To make your indoor air cleaner, experts suggest controlling pollution sources, using fresh air, and air cleaning devices like HEPA filters1113. By doing these things, you can make your home healthier for everyone111213.
Top NASA-Recommended Air-Purifying Plants
Some people think houseplants can fix all air pollution issues, but research shows certain plants can help clean your home’s air. NASA’s Clean Air Study14 looked into natural ways to purify air indoors. It found several houseplants that can remove pollutants like formaldehyde and benzene14.

- Areca Palm
NASA says put one plant for every 100 square feet of your home14. For a 1800-square-foot home, you should have 15-18 of these plants14. Plants like the Areca Palm and Spider Plant are great at cleaning indoor air. They fit well in living rooms and kids’ playrooms14.
Care and Maintenance Tips for Indoor Plants
To keep these plants working well, take good care of them. This means watering, pruning, and cleaning leaves regularly15. With proper care, these plants can make your home look better and breathe cleaner air14.
Houseplants aren’t a full fix for air pollution, but they can help. Adding these NASA-recommended plants to your space can make the air better to breathe16. Knowing how to care for them helps you get the most out of their air-purifying benefits15.
“Houseplants are not the panacea for indoor air pollution, but they can be part of the solution.”
It’s important to use plants along with other air cleaners for the best air quality161415.
Striking the Right Balance: Plants and Other Air-Cleaning Solutions
Houseplants can help improve indoor air quality, but they’re not the only solution. Adding a few air-purifying plants to your home can help remove harmful compounds and increase oxygen levels17. However, they should be part of a bigger plan that includes air purifiers and good ventilation17. This mix can make your home healthier without just counting on plants.
Some top air-cleaning plants are Dracaena, Peace Lily, Spider Plant, Aloe Vera, and Aglaonema17. These plants are great at removing toxins like formaldehyde and benzene from your home17. For example, Dracaena is easy to care for and Peace Lilies and Spider Plants are good at cleaning the air17. Aloe Vera and Aglaonema also have extra benefits, making them great for any room.
But remember, plants aren’t the only answer to clean air17. NASA found that you’d need many plants to really make a difference in air quality17. For the best air, use plants, air purifiers, and good ventilation together17. This way, you can keep your indoor air clean and fresh.
Some plants like Cacti and Asparagus Ferns can also block harmful EMF from devices18. Putting these plants near your electronics can help protect you from EMF radiation18.
To get the best air quality, mix plants with air purifiers and good airflow171819. This balanced approach helps create a healthier space for everyone.
“Indoor air can be up to five times more polluted than outdoor air.”19
