By Emma Johnson · July 21, 2026

# Indoor Air Purifying Plants: Breathe Easier at Home Indoor air can be 2-5 times more polluted than outdoor air due to volatile organic compounds (VOCs) from furniture, paint, cleaning products, and building materials. Certain houseplants naturally filter these toxins while adding beauty and humidity to your living spaces. ## The Science Behind Plant Air Purification NASA's Clean Air Study (1989) demonstrated that common houseplants can remove up to **87% of indoor air toxins** in 24 hours. Plants absorb pollutants through their leaves and roots, where soil microorganisms break them down into usable nutrients. ### What Plants Remove - **Formaldehyde**: Found in pressed wood, carpets, adhesives - **Benzene**: Found in plastics, resins, tobacco smoke - **Trichloroethylene**: Found in dry cleaning, printing ink - **Xylene**: Found in paint, varnish, car exhaust - **Ammonia**: Found in cleaning products, fertilizers ## Top 12 Air Purifying Houseplants ### 1. Snake Plant (Sansevieria trifasciata) - **Removes**: Formaldehyde, benzene, xylene, trichloroethylene - **Light**: Low to bright indirect - **Water**: Every 2-3 weeks (let dry completely) - **Special**: Releases oxygen at night - perfect for bedrooms - **Difficulty**: Very Easy ### 2. Spider Plant (Chlorophytum comosum) - **Removes**: Formaldehyde, xylene, carbon monoxide - **Light**: Bright indirect - **Water**: Weekly (keep slightly moist) - **Special**: Produces baby plantlets for easy propagation - **Difficulty**: Easy ### 3. Peace Lily (Spathiphyllum wallisii) - **Removes**: Formaldehyde, benzene, trichloroethylene, ammonia - **Light**: Low to medium indirect - **Water**: Weekly (droops when thirsty) - **Special**: One of few flowering air purifiers - **Caution**: Toxic to pets ### 4. Boston Fern (Nephrolepis exaltata) - **Removes**: Formaldehyde, xylene - **Light**: Bright indirect - **Water**: Keep consistently moist, mist daily - **Special**: Excellent natural humidifier ### 5. Rubber Plant (Ficus elastica) - **Removes**: Formaldehyde - **Light**: Bright indirect - **Water**: Every 1-2 weeks - **Special**: Large leaves = more filtering surface area ### 6. Aloe Vera (Aloe barbadensis) - **Removes**: Formaldehyde, benzene - **Light**: Bright direct or indirect - **Water**: Every 2-3 weeks - **Special**: Gel has medicinal properties for burns ### 7. Chinese Evergreen (Aglaonema commutatum) - **Removes**: Formaldehyde, benzene - **Light**: Low to medium - **Special**: Thrives in low light - great for offices ### 8. Golden Pothos (Epipremnum aureum) - **Removes**: Formaldehyde, benzene, xylene, carbon monoxide - **Light**: Low to bright indirect - **Water**: Every 1-2 weeks - **Special**: Trailing habit - beautiful on shelves ### 9. English Ivy (Hedera helix) - **Removes**: Formaldehyde, benzene, trichloroethylene, mold spores - **Special**: Reduces airborne mold - great for bathrooms ### 10. Bamboo Palm (Chamaedorea seifrizii) - **Removes**: Formaldehyde, benzene, trichloroethylene - **Special**: Adds tropical humidity, pet-safe ### 11. Dracaena (Dracaena marginata) - **Removes**: Formaldehyde, benzene, trichloroethylene, xylene - **Special**: Architectural form, slow grower ### 12. Areca Palm (Dypsis lutescens) - **Removes**: Formaldehyde, benzene, xylene, toluene - **Special**: Top-rated humidifier plant ## Room-by-Room Placement Guide ### Bedroom (Night Oxygen + Calm) - Snake plant (oxygen at night) - Aloe vera (easy care, medicinal) - Peace lily (humidifying, beautiful) ### Living Room (Statement + Function) - Rubber plant (large, dramatic) - Areca palm (humidifying, tropical) - Golden pothos (trailing, versatile) ### Bathroom (Humidity Lovers) - Boston fern (loves moisture) - English ivy (reduces mold) - Spider plant (tolerates low light) ## How Many Plants Do You Need? NASA researchers recommend: - **1 plant per 100 square feet** for effective air purification - A mix of different species targets more pollutants - Larger plants with more leaf surface area filter more For a 1,500 sq ft home: aim for 15-20 plants of varying sizes. ## FAQ **Q: Are air purifying plants safe for pets?** A: Some are toxic (peace lily, pothos, ivy, dracaena). Pet-safe options: spider plant, bamboo palm, areca palm, boston fern. **Q: Do plants really clean the air?** A: Yes, but you need adequate numbers. A single plant in a large room has minimal measurable impact. ## Conclusion Air purifying plants offer a natural, beautiful way to improve indoor air quality.
