Which Plants Are the Best Oxygen Producers at Night?

Updated: May 29

Incorporating houseplants into your home not only adds to the aesthetic appeal but also brings numerous health benefits. While most plants release oxygen during the day through photosynthesis, some unique plants continue to produce oxygen even at night, improving indoor air quality around the clock. These plants follow a different photosynthetic pathway known as CAM (Crassulacean Acid Metabolism), which allows them to uptake carbon dioxide at night. Here’s a detailed look at some of the best night-time oxygen producers and their benefits for indoor air quality.

1. Snake Plant (Sansevieria trifasciata)

  • Night-Time Oxygen Production: The snake plant is a CAM plant that releases oxygen at night, making it an excellent plant for bedrooms.

  • Air Purification: It is known to remove toxins such as formaldehyde, benzene, xylene, and toluene from the air.

Care Tips:

  • Light: Tolerates low to bright indirect light.

  • Watering: Water sparingly; allow the soil to dry out between waterings.

  • Maintenance: Dust the leaves occasionally to keep them clean and ensure better air purification.

2. Aloe Vera

  • Night-Time Oxygen Production: Aloe Vera releases oxygen at night and absorbs carbon dioxide, promoting better sleep.

  • Air Purification: It helps in removing common indoor pollutants like formaldehyde and benzene.

  • Medicinal Properties: The gel from aloe leaves has soothing properties for burns and skin irritations.

Care Tips:

  • Light: Prefers bright, indirect sunlight.

  • Watering: Water every 3 weeks or when the soil is completely dry.

  • Maintenance: Ensure the pot has good drainage to prevent root rot.

3. Areca Palm (Dypsis lutescens)

  • Night-Time Oxygen Production: The Areca palm produces oxygen at night and increases humidity, which can be beneficial for respiratory health.

  • Air Purification: It is effective in removing pollutants like xylene and toluene from the air.

Care Tips:

  • Light: Thrives in bright, indirect light.

  • Watering: Keep the soil consistently moist but not waterlogged.

  • Maintenance: Mist the leaves regularly to maintain humidity and keep the plant healthy.

4. Christmas Cactus (Schlumbergera bridgesii)

  • Night-Time Oxygen Production: Like other CAM plants, the Christmas cactus releases oxygen at night.

  • Air Purification: It contributes to improved air quality by absorbing CO2 and releasing oxygen.

Care Tips:

  • Light: Prefers bright, indirect light.

  • Watering: Water thoroughly when the top inch of soil feels dry.

  • Maintenance: Provide a well-draining potting mix to prevent root rot.

5. Peace Lily (Spathiphyllum)

  • Night-Time Oxygen Production: Peace lilies produce oxygen at night, which can help improve air quality in bedrooms.

  • Air Purification: They are known for their ability to remove toxins such as ammonia, benzene, formaldehyde, and trichloroethylene from the air.

Care Tips:

  • Light: Best in low to bright indirect light.

  • Watering: Keep the soil consistently moist but not waterlogged.

  • Maintenance: Mist the leaves occasionally to maintain humidity and wipe them clean to enhance their air-purifying ability.

6. Spider Plant (Chlorophytum comosum)

  • Night-Time Oxygen Production: Spider plants release oxygen at night and are effective in improving indoor air quality.

  • Air Purification: They help remove pollutants such as formaldehyde and xylene.

Care Tips:

  • Light: Thrives in bright, indirect light but can tolerate lower light conditions.

  • Watering: Water when the soil starts to dry out.

  • Maintenance: Trim any brown tips and occasionally dust the leaves to keep the plant healthy.

7. Gerbera Daisy (Gerbera jamesonii)

 Gerbera Daisy


  • Night-Time Oxygen Production: Gerbera daisies produce oxygen at night and can improve sleep quality by maintaining fresh air.

  • Air Purification: They help in removing toxins like benzene and trichloroethylene from the air.

Care Tips:

  • Light: Needs bright light, ideally with some direct sunlight.

  • Watering: Keep the soil consistently moist but ensure good drainage.

  • Maintenance: Remove spent flowers to encourage more blooms and maintain plant health.


Incorporating plants that produce oxygen at night into your home can significantly enhance indoor air quality and promote better health. These plants not only contribute to a fresher atmosphere but also help in removing common indoor pollutants, ensuring that the air you breathe is cleaner and healthier. Whether you place them in your bedroom, living room, or office, these low-maintenance plants can make a big difference in creating a more pleasant and healthier indoor environment. Happy planting!
