Low-Maintenance Plants That Improve Air Quality
May 4, 2025

The NASA Clean Air Study highlighted certain houseplants that effectively remove volatile organic compounds (VOCs) like formaldehyde, benzene, and trichloroethylene from indoor air. These low-maintenance varieties require minimal effort yet deliver measurable air-quality benefits.
Snake Plant (Sansevieria trifasciata)
Air-Purifying: Can reduce formaldehyde levels by up to 10% within 24 hours.
Care: Thrives in low light. Water every 2–3 weeks, letting soil dry between waterings. Use well-draining potting mix.
ZZ Plant (Zamioculcas zamiifolia)
Air-Purifying: Removes xylene and toluene efficiently.
Care: Tolerates low to bright indirect light. Water sparingly—once a month—and avoid overwatering.
Spider Plant (Chlorophytum comosum)
Air-Purifying: Effective at reducing carbon monoxide and xylene.
Care: Prefers bright, indirect light. Keep soil lightly moist and propagate spiderettes in water or soil.
Pothos (Epipremnum aureum)
Air-Purifying: Removes formaldehyde, benzene, and xylene.
Care: Adapts to low light. Water when the top 2 inches of soil feel dry and trim vines to maintain shape.
Peace Lily (Spathiphyllum)
Air-Purifying: Eliminates ammonia, benzene, formaldehyde, and trichloroethylene.
Care: Prefers bright, indirect light. Keep soil evenly moist; drooping leaves signal thirst.
General Care & Placement Tips
- Place at least one plant per 100 sq ft for optimal VOC removal.
- Combine different species to target a broader range of toxins.
- Rotate plants monthly to ensure even growth and balanced light exposure.
- Use pots with drainage holes and a gravel layer to prevent root rot.
- Wipe leaves periodically to remove dust and maximize photosynthesis.
