Do succulents clean the air? (The Truth)

Succulents contribute to cleaner air, but their air-purifying abilities are limited compared to other plants. While they release oxygen and absorb carbon dioxide through photosynthesis, their impact on removing harmful pollutants like volatile organic compounds (VOCs) is minimal. 

Some succulents, like snake plants and aloe vera, are known to eliminate specific toxins, albeit slower than other air-purifying plants. In conclusion, succulents can play a small role in improving air quality, but relying solely on them for air purification would not be sufficient.

How do succulents improve air quality?

Succulents purify the air by absorbing harmful toxins and pollutants through the pores on their surfaces.

They take in carbon dioxides and toxic gases, such as formaldehyde and benzene, commonly found in household items like building materials, insulation, glues, and paints.

In addition to removing these pollutants, succulents release oxygen and increase humidity in the indoor environment. However, it is important to note that the air-purifying capabilities of succulents are limited compared to other plants.

Here is a list of specific toxins that succulents can remove from the air:

  • Benzene is a common pollutant in gasoline, paint, and tobacco smoke. Plants like Aloe Vera and Jade Plant can help remove benzene from the air.
  • Formaldehyde:  A toxic chemical found in many household products, such as furniture, carpets, and cleaning supplies. Spider plants, Snake Plants, and Aloe Vera are known for purifying the air from formaldehyde.
  • Trichloroethylene: A solvent used in dry cleaning and industrial processes. Peace Lily and Aloe Vera can help remove trichloroethylene from indoor air.
  • Ammonia: A common ingredient in household cleaners and fertilizers. Flamingo Lily and Peace Lily are effective in removing ammonia from the air.
  • Xylene: A chemical found in paint, rubber, and printing inks. Aloe Vera, Spider Plant, and Jade Plant can help remove xylene from indoor air.
  • Toluene is a solvent found in paint thinners, nail polish, and adhesives. Spider plants and Snake Plants help reduce toluene levels in the air.

Are there any potential risks or drawbacks of keeping succulents indoors?

Yes, there are some potential risks and drawbacks to keeping succulents indoors. While these plants can provide numerous benefits, such as improving air quality and adding aesthetic value, it is essential to consider the following factors:

  • Toxicity to pets: Some succulents, like Aloe Vera, Jade Plant, and Snake Plant, can be toxic to pets, especially cats and dogs if ingested. These plants can cause symptoms such as vomiting, diarrhea, and lethargy. Ensure that you keep toxic succulents out of the reach of pets, or choose pet-safe options like Haworthia, Echeveria, and Sedum.
  • Overwatering: Succulents are prone to root rot if they are overwatered or left in water. Indoor environments can sometimes lead to less evaporation and increased humidity, increasing the risk of overwatering. Ensure that you use well-draining soil and a pot with drainage holes, and follow a proper watering schedule to avoid this issue.
  • Insufficient light: Succulents require sunlight to thrive and maintain their vibrant colors. Indoor spaces may not always provide enough natural light, leading to etiolation (stretching) or plant fading. To address this issue, place your succulents near a bright window or use a grow light to supplement their light needs.
  • Pest infestations: Succulents can attract pests like mealybugs, spider mites, and scale insects, which can be more challenging to control indoors. Regularly inspect your plants for signs of pests and treat them promptly using insecticidal soap, neem oil, or other appropriate methods.
  • Limited air circulation: Indoor environments often have limited air circulation compared to outdoor spaces, contributing to pest infestations and fungal issues. Ensure that your succulents have enough space between them for proper airflow, and consider using a small fan to improve air circulation if needed.
  • Allergies: While succulents are less likely to cause allergies than other plants, some individuals may still be sensitive to their pollen or sap. If you have a known plant allergy, take precautions when handling succulents or choose hypoallergenic options.

Factors Affecting Succulents’ Air Purification Abilities

Light Exposure

Effect on Air Purification: Adequate light exposure is crucial for succulents to perform photosynthesis, which helps them absorb and break down toxins in the air. Insufficient light can hinder their air purification abilities.

Light Exposure
Light Exposure

How to Optimize: Place succulents near a bright window that receives ample sunlight or use a grow light to ensure they receive the necessary light for optimal air purification.

Plant Size and Quantity

Effect on Air Purification: Larger plants or a higher quantity of plants can absorb more toxins and release more oxygen, thus improving their air purification capabilities.

How to Optimize: Choose larger succulents or have multiple plants in your indoor space to enhance their air-purifying effects. Ensure that there is enough space between plants for proper air circulation.

Humidity Levels

Effect on Air Purification: High humidity levels can reduce a succulent’s ability to absorb toxins from the air. Excess humidity can also lead to fungal issues and pest infestations.

How to Optimize: Maintain appropriate humidity levels in your indoor space by using a dehumidifier or increasing air circulation with a fan. Regularly check and adjust the humidity levels to create an optimal environment for succulents.

Soil Quality and Drainage

Effect on Air Purification: Well-draining soil allows succulents to grow healthy root systems, which is essential for absorbing nutrients and toxins from the air. Poor soil quality or drainage can lead to root rot and hinder their air purification abilities.

How to Optimize: Use a well-draining soil mix specifically designed for succulents, and ensure that the pot has drainage holes to prevent waterlogging. Avoid overwatering your plants, and allow the soil to dry out between waterings.

Plant Health and Maintenance

Effect on Air Purification: Healthy succulents are more effective at purifying the air. Pests, diseases, and other health issues can reduce their air purification abilities.

Plant Health and Maintenance

How to Optimize: Regularly inspect your succulents for signs of pests or diseases and treat them promptly. Prune dead or diseased leaves to promote healthy growth. Fertilize your succulents to support their overall health and air purification capabilities.

Air Circulation

Effect on Air Purification: Proper air circulation is essential for succulents to effectively absorb and break down toxins in the air. Limited air circulation can reduce their air purification abilities and increase the risk of pest infestations and fungal issues.

How to Optimize: Ensure enough space between your succulents for proper airflow. Consider using a small fan to improve air circulation in your indoor space, especially in areas with limited natural airflow.
