Which Types of Plants Give Off Oxygen at Night?

Updated: May 29

Creating a healthy living space involves more than just cleaning and organizing your home; it’s also about improving the quality of the air you breathe. While many houseplants provide oxygen during the day, certain plants have the unique ability to continue producing oxygen even at night. These plants utilize a special type of photosynthesis called CAM (Crassulacean Acid Metabolism), which allows them to take in carbon dioxide during the night and release oxygen. Here are some top plants that not only beautify your home but also boost oxygen levels at night, contributing to better indoor air quality and overall health.

The Power of Night-Time Oxygen Producers

Unlike typical plants that photosynthesize only during daylight, CAM plants keep working after the sun goes down. This unique feature makes them ideal for bedrooms and other areas where you spend your evenings. Here’s a closer look at some of the best plants for this purpose:

1. Snake Plant (Sansevieria trifasciata)

  • Air Purification: Snake plants remove formaldehyde, benzene, xylene, and toluene.

  • Care: They require minimal water and can tolerate low light, making them an easy addition to any room.

2. Aloe Vera

Integrating Night-Time Oxygen Producers into Your Home

These plants will help you breathe easier and sleep better by maintaining a steady supply of fresh oxygen.


Incorporating plants that produce oxygen at night into your home can significantly enhance your indoor air quality. These plants not only contribute to a healthier living environment but also add a touch of natural beauty to your home decor. By choosing low-maintenance options like snake plants, aloe vera, and peace lilies, you can enjoy the benefits of cleaner air and better health with minimal effort. Happy gardening!
