In today’s fast-paced world, maintaining a healthy indoor environment is more important than ever. Many people are aware of the importance of air purifiers, but did you know that certain indoor plants can also act as natural air purifiers? Not only do they improve indoor air quality, but they also add a refreshing aesthetic to your home. Here’s a deep dive into some of the best houseplants that will help purify the air in your living space, based on NASA’s Clean Air Study and other expert sources.
1. Spider Plant (Chlorophytum comosum)
Benefits:
Removes formaldehyde, xylene, and toluene.
Spider plants are one of the most popular air-purifying plants, known for their ability to remove harmful chemicals like formaldehyde, xylene, and toluene from the air. These substances are commonly found in household items like furniture, paints, and cleaning products. In addition to purifying the air, the Spider Plant also produces oxygen, improving the overall air quality in your home.
Care
Thrives in indirect sunlight and tolerates a range of temperatures.
Spider plants thrive in indirect sunlight, making them perfect for placement in any room with natural light but not direct exposure. They are also highly adaptable, tolerating a range of temperatures and humidity levels. The best part? They’re incredibly low-maintenance and can survive even with occasional neglect.
Why It Works:
Spider plants absorb toxins through their leaves, making them effective in reducing indoor air pollution. They can even tolerate various lighting conditions and still provide an air-purifying effect. If you’re a beginner plant owner, this is a perfect choice.
- Additional Tip: Keep the soil slightly moist but avoid overwatering, as Spider Plants do not like soggy roots. Source
2. Snake Plant (Sansevieria trifasciata)
Benefits:
Snake plants, also known as “Mother-in-law’s Tongue,” are highly effective at filtering formaldehyde, benzene, xylene, toluene, and nitrogen oxides. These toxins often enter your home through household products like paints, plastics, and adhesives. The Snake Plant is unique because it continues to purify the air even at night when many plants stop their photosynthesis process.
Care:
Snake plants are nearly indestructible. They thrive in low light and can go for long periods without water. They do well in a variety of temperatures and can be placed in almost any part of your home, making them perfect for those with a busy lifestyle who might forget about their plants.
Why It Works:
Snake plants are particularly effective at absorbing toxins from the air, as their stiff, upright leaves trap and neutralize pollutants. Their ability to produce oxygen while consuming carbon dioxide at night makes them excellent bedroom companions.
Additional Tip: Water sparingly, as Snake Plants prefer dry conditions and can develop root rot if overwatered. Source
3. Peace Lily (Spathiphyllum)
Benefits:
Peace Lilies are known for their ability to remove toxins like formaldehyde, benzene, trichloroethylene, xylene, and ammonia from the air.
