Plants that absorb high levels of CO₂ are an excellent addition to any indoor space, as they help purify the air while adding beauty. Choosing plants with effective CO₂ absorption rates can boost indoor air quality, providing a healthier environment in homes and offices. Here are ten top plant choices known as the best plants for CO2 absorption. Along with their specific care needs, covering pot, soil, light, water, and fertilizer requirements. I just love these pot head planters for my pothos, philodendrons, spider plants, air plants and so much more. They are a great conversation piece and make great gifts with a plant in them!!
1. Philodendron
Philodendrons are fantastic for CO₂ absorption, making them ideal for improving indoor air quality. They thrive in pots with drainage holes, as well as in lightweight, well-draining soil mixed with peat moss or perlite. Philodendrons prefer indirect light and do well in low to moderate light conditions, but too much direct sunlight can cause leaf burn. Water them when the top inch of soil feels dry, taking care to avoid overwatering, which can lead to root rot. Regularly fertilize them during the growing season with a balanced, diluted liquid fertilizer. With occasional pruning to remove dead leaves, philodendrons remain lush, vibrant, and healthy indoors.

2. Snake Plant (Sansevieria trifasciata)
Snake plants are known for their resilience and excellent air-purifying abilities. Plant them in a small to medium pot with drainage holes, and choose a cactus or succulent soil mix that drains well. These plants thrive in low to bright, indirect light, making them versatile for various room settings. Water them sparingly—only when the soil is completely dry. Fertilize once every two months in spring and summer with a half-strength balanced fertilizer to keep them healthy. For more in depth post on how to grow and care for Snake Plant just click here.
3. Spider Plant (Chlorophytum comosum)
The spider plant is efficient at removing CO₂ and is easy to grow indoors. It does well in a small pot with drainage and a lightweight, well-draining potting mix. Spider plants prefer indirect light, but they also adapt to lower light. Water them when the top inch of soil is dry, and avoid overwatering. During spring and summer, fertilize monthly with a balanced liquid fertilizer to promote healthy, vibrant foliage. For more in depth post on how to grow and care for Spider Plant just click here.
4. Rubber Plant (Ficus elastica)
Rubber plants are excellent CO₂ absorbers and make great statement plants indoors. They do best in a medium pot with drainage and a soil mix that retains moisture without getting soggy, like peat-based or cactus mix. Rubber plants thrive in bright, indirect light but can also tolerate lower light levels. Water when the top inch of soil feels dry, and avoid waterlogging. Feed them monthly in spring and summer with a balanced fertilizer to support growth and glossy leaves. For more in depth post on how to grow and care for Rubber Plant just click here.
5. Boston Fern (Nephrolepis exaltata)
Boston ferns not only absorb CO₂ effectively but also add a lush, tropical look. Use a hanging pot or one with good drainage, and fill it with a rich, peat-based potting soil. Boston ferns love indirect light and humid conditions, so keep them near a bathroom window or use a humidity tray. Water frequently to keep the soil consistently moist, especially during warmer months. Fertilize every two weeks in spring and summer with a half-strength liquid fertilizer to encourage thick, green foliage.

6. Peace Lily (Spathiphyllum)
The Peace Lily is known for its ability to absorb CO₂ and other pollutants. This plant prefers a medium-sized pot with drainage and rich, well-draining soil. Peace lilies thrive in low to medium, indirect light, making them ideal for offices or shadier rooms. Keep the soil slightly moist, but avoid standing water. Feed monthly with a balanced fertilizer during the growing season to promote its iconic white blooms and healthy leaves. For more in depth post on how to grow and care for Peace Lily just click here.
7. Aloe Vera (Aloe barbadensis)
Aloe Vera, beyond its medicinal uses, absorbs CO₂ well and adds a sleek touch to indoor decor. It needs a small to medium pot with drainage holes and cactus soil for optimal drainage. Place it in bright, indirect sunlight to keep it thriving, and avoid overwatering—only water when the soil is completely dry. Fertilize sparingly, about once or twice a year, with a diluted succulent or cactus fertilizer in the spring. For more in depth post on how to grow and care for Aloe Vera just click here.
8. Pothos (Epipremnum aureum)
Pothos is a popular indoor plant that purifies air and removes CO₂. It does well in a small to medium pot with drainage and a general-purpose houseplant soil mix. Pothos can handle various lighting conditions, from low light to bright, indirect light, making it versatile. Water when the top inch of soil is dry, and avoid letting it sit in water. Fertilize every two months during the growing season with a balanced liquid fertilizer for a full, trailing appearance. For more in depth post on how to grow and care for Pothos just click here.
9. Bamboo Palm (Chamaedorea seifrizii)
The Bamboo Palm, with its elegant, feathery fronds, efficiently absorbs CO₂ and thrives indoors. Use a medium pot with good drainage, and fill it with a well-draining, slightly acidic soil mix. Place the plant in bright, indirect light, although it can tolerate some shade. Keep the soil evenly moist but not waterlogged, and mist it occasionally to increase humidity. Feed monthly with a balanced liquid fertilizer during spring and summer to maintain healthy, green fronds. For more in depth post on how to grow and care for Bamboo Palm just click here.
10. Dracaena (Dracaena marginata)
Dracaenas are great for removing CO₂ from indoor air and offer a striking vertical look. Choose a pot with drainage and fill it with loose, well-draining soil, like a peat-based or cactus mix. Place your Dracaena in moderate to bright, indirect light. Allow the top inch or two of soil to dry out between waterings to prevent root rot. Fertilize every two months with a balanced fertilizer to support its long, slender leaves and encourage vibrant growth. For more in depth post on how to grow and care for Dracaena just click here.
