Succulents have long been admired for their beauty, ease of care, and compact charm—but there’s more to these resilient plants than just good looks. In recent years, succulents as air purifiers have become a growing trend among plant lovers and wellness seekers alike.
These water-storing wonders are now taking center stage not only on windowsills but also in the conversation about indoor air quality.
If you’re someone who’s looking to add a little green life to your home and breathe cleaner, healthier air at the same time, this guide will walk you through everything you need to know.
From how succulents clean the air to which varieties work best, we’ll explore their role as natural purifiers and how you can make the most of them in your indoor space.
How Succulents Help Purify Air
We spend up to 90% of our time indoors, and indoor air can be more polluted than outdoor air—especially when we’re surrounded by synthetic materials, cleaning products, or stale ventilation. Luckily, nature offers some help.
Succulents like Aloe Vera, Snake Plant, and Jade Plant help improve indoor air by:
- Releasing oxygen during both day and night (thanks to CAM photosynthesis)
- Absorbing harmful volatile organic compounds (VOCs) like benzene and formaldehyde
- Maintaining humidity levels through slow water evaporation
What makes succulents especially unique is their ability to perform photosynthesis at night. Unlike most plants that take in CO₂ during the day, some succulents open their stomata at night, releasing oxygen while absorbing carbon dioxide—making them ideal bedroom companions.
Even though succulents may not dramatically purify large spaces on their own, they contribute to a fresher, more breathable environment—especially when grouped together or placed strategically.
Scientific Insights on Air-Cleaning Succulents
You may have heard about NASA’s famous Clean Air Study, which highlighted the power of certain houseplants in removing toxins from indoor spaces.
While succulents weren’t the main focus of that study, many of the same principles apply.
What is CAM Photosynthesis?
Crassulacean Acid Metabolism (CAM) is a specialized type of photosynthesis that many succulents follow. It allows them to:
- Absorb carbon dioxide at night
- Store CO₂ as malic acid
- Convert it to oxygen and sugars during daylight
This water-efficient, nocturnal breathing system means that succulents don’t just sit around looking pretty—they’re working round-the-clock to clean the air, reduce CO₂ buildup, and even improve your sleep quality.
Research also suggests that environments enriched with plants can boost mood, reduce anxiety, and improve cognitive function. Succulents do this subtly by regulating air quality, adding oxygen, and enhancing visual aesthetics.
Best Succulents for Air Purification
Looking to boost your indoor air naturally? Here are ten of the best succulents that purify the air and look amazing doing it.
1. Aloe Vera
A household favorite, Aloe Vera is known not only for its healing gel but also its ability to remove formaldehyde and benzene from indoor air. It thrives in bright light and needs minimal watering.
2. Snake Plant (Sansevieria)
Sometimes called mother-in-law’s tongue, this upright succulent is a powerhouse for releasing oxygen at night. It filters toxins like toluene and formaldehyde and can survive in low light, making it ideal for bedrooms and bathrooms.
3. Echeveria
With its rose-like rosettes, Echeveria brings charm and air-refreshing qualities to any space. It’s particularly good at oxygen release and humidity control.
4. Jade Plant (Crassula ovata)
This chunky-leaved plant is believed to bring luck and prosperity. It also helps absorb CO₂ and can purify small amounts of indoor air when grouped with others.
5. Zebra Haworthia
This stylish striped plant is a low-maintenance option perfect for desks and small shelves. It quietly filters air while requiring very little water or sunlight.
6. Panda Plant (Kalanchoe tomentosa)
Fuzzy, silvery leaves with chocolate tips make the Panda Plant a visual treat. It purifies air subtly while doubling as a cute decorative piece.
7. Christmas Cactus (Schlumbergera)
Not just a holiday beauty, the Christmas Cactus also helps maintain moisture levels and improve indoor air. It prefers filtered light and a bit more watering than desert succulents.
8. Burro’s Tail (Sedum morganianum)
Trailing over hanging pots, Burro’s Tail looks great and plays a role in air purification. Its dense leaf clusters help absorb carbon dioxide and release oxygen.
9. String of Pearls
Dramatic and delicate, this succulent cleans the air while adding character to your home décor. It’s best placed in bright, indirect light with careful watering.
10. Ponytail Palm (Beaucarnea recurvata)
Technically a succulent, this elegant, bulbous plant purifies air and adds a bold touch to modern interiors. It stores water in its trunk and thrives with neglect.
When arranged thoughtfully, these plants can transform your space into a mini green oasis that not only elevates aesthetics but also improves your breathing environment.
Where to Place Succulents for Maximum Benefit
Strategic placement is key to making the most of your air-purifying succulents.
- Bedrooms: Snake Plant, Aloe Vera, and Jade Plant are excellent for nighttime oxygen release.
- Home Office or Study: Echeveria or Zebra Haworthia can help improve focus and air freshness.
- Kitchens: Try Panda Plants or Christmas Cactus in well-lit spots with good airflow.
- Bathrooms: Snake Plants thrive in humidity and low light.
- Living Rooms: Make centerpieces with Ponytail Palms or trailing succulents like String of Pearls.
Place succulents where they’ll get indirect light and proper air circulation. Avoid cluttering too many in dark corners or sealing them off in closed terrariums unless they’re meant for short-term display.
Care Tips to Keep Your Succulents Healthy
To enjoy both the air-purifying benefits and the visual delight of your succulents, you’ll need to take good care of them. Here’s how to do that, the easy way:
Light
Most succulents need bright, indirect sunlight. A south-facing window works best for most types, but some (like Snake Plant) tolerate low light.
Watering
Overwatering is the #1 killer of succulents. Water deeply but only when the soil is completely dry. For pots without drainage, water even more sparingly.
Soil
Use a well-draining cactus or succulent mix. Add sand or perlite if necessary.
Temperature and Humidity
Succulents generally prefer dry, warm conditions—ideal for indoor settings. Keep them away from AC vents and radiators.
Pest Control
Succulents are fairly pest-resistant but can attract mealybugs or spider mites. Use neem oil or a mild soap spray to keep them clean without chemicals.
Benefits Beyond Air Purification
Succulents do more than just clean your air—they subtly contribute to a calmer, healthier indoor atmosphere in several unexpected ways:
1. Natural Humidifiers
While succulents release less moisture than tropical plants, they still contribute to balancing humidity levels, especially in dry indoor environments. A collection of small succulents can gently lift dry air in air-conditioned spaces.
2. Stress Reduction and Focus
Studies have shown that indoor plants—including succulents—help reduce stress, fatigue, and mental exhaustion. Just having greenery nearby can improve mood, increase focus, and support creativity, making them perfect for home offices and study nooks.
3. Allergy Relief
Succulents help filter dust and allergens from the air, reducing irritation for sensitive individuals. Their waxy, compact surfaces also accumulate fewer airborne particles than larger foliage houseplants.
4. Eco-Friendly Décor
Unlike artificial purifiers that use electricity and filters, succulents are low-impact, energy-free air purifiers. Their longevity and low resource needs make them an excellent sustainable choice.
Common Misconceptions About Succulent Air Purification
Let’s clear up a few misunderstandings to help you enjoy realistic expectations:
“Succulents can replace air purifiers completely.”
No. While they help improve indoor air quality, succulents can’t match the efficiency of mechanical HEPA filters. Their purification power is modest, but combined with ventilation and clean habits, they do contribute to healthier indoor environments.
“All succulents purify air the same way.”
Not quite. Some succulents, like Snake Plant and Aloe Vera, have unique chemical-absorbing capabilities and nocturnal oxygen release. Others provide aesthetic and humidity benefits without targeting VOCs.
“More succulents = better air.”
To a degree, yes—but you still need light, proper watering, and airflow. Cramming too many plants in a poorly lit or stuffy room may backfire by encouraging mold or attracting pests.
Creative Ways to Style Succulent Air Purifiers at Home
Adding succulents to your home is an opportunity to blend beauty with wellness. Here are some styling ideas that combine function with flair:
