Best Oxygen-Producing Houseplants for Indoor Air Quality

NASA-Approved Plants for Cleaner Air

Research by NASA identified several common houseplants that effectively remove volatile organic compounds (VOCs) and convert CO₂ to oxygen. For a lung cancer patient—or anyone wanting healthier air—these hardy, broad-leaved plants are excellent choices:

• Snake plant (Sansevieria trifasciata) – extremely tough, low light tolerant
• Peace lily (Spathiphyllum 'Mauna Loa') – beautiful blooms, good air cleaner
• Chinese evergreen (Aglaonema modestum) – durable, variegated foliage
• Bamboo palm (Chamaedorea seifrizii) – graceful, humidifies air
• Golden pothos (Epipremnum aureum) – fast-growing, trailing
• Spider plant (Chlorophytum comosum) – easy, produces plantlets
• Dracaena varieties (Janet Craig, Warneckii, Marginata, Cornstalk) – upright, architectural
• Heartleaf philodendron (Philodendron scandens) – classic trailing plant
• English ivy (Hedera helix) – needs bright light, good for hanging
• Weeping fig (Ficus benjamina) – tree form, needs stability

Choose based on light availability and care level. Snake plant and pothos are the most forgiving.
