What Plants Produce the Most Oxygen?
Plants are the foundation of life on Earth, providing oxygen through the process of photosynthesis. While all plants produce oxygen, some are more efficient than others. Here are some of the plants that produce the most oxygen:
1. Phytoplankton
Phytoplankton are microscopic plants that live in the ocean and are responsible for producing a significant portion of the world’s oxygen. According to EarthSky, phytoplankton contribute between 50 to 85 percent of the oxygen in Earth’s atmosphere. These tiny plants drift with ocean currents and use sunlight, carbon dioxide, and nutrients to produce food and oxygen through photosynthesis.
2. Areca Palm
The Areca palm, also known as the golden palm or butterfly palm, is a popular indoor plant that produces a high amount of oxygen. According to Nurserylive, having two large Areca palm plants in close proximity can significantly increase the oxygen levels in your home. These tropical trees not only produce oxygen but also remove harmful pollutants such as formaldehyde, xylene, benzene, and toluene from the air.
3. Snake Plant
The snake plant, also known as mother-in-law’s tongue, is renowned for its efficiency in producing oxygen. It is one of the most popular indoor plants, finding its way into both homes and offices. According to NASA-sponsored clean air research, the snake plant purifies the air by absorbing formaldehyde, nitrogen oxide, xylene, benzene, and trichloroethylene. This plant is unique in that it photosynthesizes during the day and respirates at night, absorbing oxygen at night.
4. Money Plant (Golden Pothos)
The money plant, also known as the golden pothos, is easily found in many homes and is able to reduce carbon dioxide at a faster rate than other plants, thereby increasing oxygen levels. It has many air-purifying qualities that can remove chemicals and air pollutants like xylene and formaldehyde with ease. The money plant is also a low-maintenance plant that needs to be watered once every 7-10 days.
5. Peace Lily
The peace lily is a popular indoor plant known for its distinctive white flower. In addition to its beauty, the peace lily is also an excellent oxygen producer. According to NASA studies, peace lilies are good at removing benzene and trichloroethylene from the air, which are common pollutants found in both homes and offices.
6. Spider Plant
The spider plant is one of the easiest indoor plants to grow and is known for its long, tendril-like leaves. It is also a great oxygen-producing plant. The spider plant is noted for filtering carbon monoxide, formaldehyde, and benzene from the air, making it a fantastic oxygen-producing indoor plant. It is also recognized for distributing positive energy and aiding in anxiety and stress management.
7. Gerbera Daisy
The Gerbera daisy is a vibrant flowering plant that not only adds color to a room but also serves as a wonderful source of oxygen. According to NASA’s Clean Air Study, the Gerbera daisy is effective in removing trichloroethylene, benzene, and formaldehyde from the air.
8. Aloe Vera
Aloe vera is well-known for its medicinal properties, but it also has air-cleaning and oxygen-increasing capabilities. The aloe vera plant is effective in removing toxins such as aldehydes and benzene from the air. Unlike most plants, it also produces oxygen at night, making it ideal for bedrooms and other enclosed spaces.
9. Tulsi (Holy Basil)
Tulsi, or holy basil, is a sacred plant found in many Indian homes. It is recognized for producing oxygen for more than 20 hours a day and absorbing hazardous gases like carbon monoxide and carbon dioxide. Tulsi leaves have a sweet aromatic smell and minty taste that freshens the surrounding air. The leaves are also eaten raw to cure cough and cold, and the essential oil extracted from the plant is used in soaps, perfumes, and shampoos.

FAQs
- Which indoor plant produces the most oxygen at night?
The snake plant (mother-in-law’s tongue) is the most effective plant found to produce oxygen at night. - Are there any indoor plants that can produce oxygen without sunlight?
While most plants require sunlight for photosynthesis, some indoor plants can survive on very low amounts of light. One important example is the ZZ plant (Zamioculcas zamiifolia), also known as the “Eternity Plant”. - Are these oxygen-producing plants safe to grow indoors?
Some plants might have spikes or leaves that may contain certain chemicals, but with a little prior knowledge about the plant’s nature and properties, these could be safely grown at homes and office spaces. - How much oxygen do indoor plants produce?
The amount of oxygen produced by indoor plants varies depending on factors such as the plant species, size, and growing conditions. However, having a variety of oxygen-producing plants in your home or office can significantly improve air quality and contribute to a healthier indoor environment. - Are there any downsides to having indoor oxygen-producing plants?
While indoor plants offer numerous benefits, it’s important to consider potential downsides, such as the risk of allergic reactions for some individuals, the potential for soil-borne diseases, and the need for proper care and maintenance to ensure the plants thrive and continue to provide oxygen.
