Top 10 Air-Purifying Plants for a Healthier Home

NASA research confirmed that certain houseplants remove harmful chemicals from indoor air. Here are the 10 best air-purifying plants and how to use them effectively.

In 1989, NASA published a landmark study showing that certain plants absorb volatile organic compounds (VOCs) — chemicals released by furniture, paint, and cleaning products. While plants alone won't replace an air purifier, they contribute meaningfully to healthier indoor air.

Top 10 Air-Purifying Plants

• Peace Lily — removes ammonia, benzene, and formaldehyde. Thrives in low light.
• Snake Plant — releases oxygen at night; absorbs CO₂ and formaldehyde.
• Pothos — excellent at removing formaldehyde and carbon monoxide.
• Dracaena — absorbs trichloroethylene and benzene.
• Areca Palm — outstanding at regulating humidity and removing xylene.
• Philodendron — highly effective at absorbing formaldehyde.
• Rubber Plant — removes formaldehyde; tolerates dry conditions.
• English Ivy — reduces airborne mold spores and allergens.
• Chrysanthemum — absorbs ammonia and benzene; most effective while flowering.
• Aloe Vera — removes formaldehyde and benzene.

How to Maximize the Effect

For meaningful air purification, aim for one 15–20 cm pot per 9 m² of floor space. Group plants together for a greater combined effect. Wipe leaves regularly to remove dust — clean leaves photosynthesize and filter air more efficiently.

Important: Pet Safety

Several top air-purifying plants — including Peace Lily, Philodendron, and Dracaena — are toxic to cats and dogs. Always check toxicity before placing plants in a home with pets.
