Friends who’ve just finished a full-home renovation or custom furnishing often wonder: “The smell indoors is still strong—what green plants can help absorb formaldehyde?”
To be honest, plants are not a magic cure for formaldehyde. They can’t replace ventilation or professional treatment. But choosing the right ones can assist with air purification, add greenery, and make the home more comfortable. Here are several easy-to-grow, reliable plants that can help absorb some formaldehyde and freshen your space.
Boston Fern
Often called the “king of formaldehyde absorption”, this plant is especially suitable for newly renovated homes. Its feathery fronds are dense and covered with tiny hairs on the underside, giving it stronger absorption capacity than many common houseplants. Boston ferns love humidity, so misting their leaves often not only keeps them healthy but also raises indoor moisture levels—helpful in dry, newly decorated rooms.
Golden Pothos
The ultimate beginner’s plant for formaldehyde absorption: inexpensive, hardy, and adaptable. Whether grown in water or soil, it thrives even in low-light corners. Its leaves and roots can absorb some formaldehyde while also balancing indoor humidity. Just be careful: its sap is mildly toxic, so keep it out of reach of children and pets. Water only when the soil dries to avoid root rot.
English Ivy
A proven formaldehyde fighter, English ivy often scores well in scientific tests for VOC absorption. It’s also very decorative—its trailing vines look elegant cascading from cabinets or shelves, perfect for placing beside wardrobes or bookshelves in a newly furnished home. Ivy prefers cooler conditions, away from heaters or direct AC drafts. Mist its leaves regularly to keep them lush. Even if you forget to water occasionally, it usually bounces back quickly.
Snake Plant (Sansevieria)
A true low-maintenance champion, snake plants not only absorb formaldehyde but also release oxygen at night—making them excellent for bedrooms. Their thick, upright leaves can filter formaldehyde, benzene, and other pollutants. They’re highly drought-tolerant, surviving weeks without water. Place them in bright, indirect light, avoid pouring water into the leaf crown, and water only when the soil is completely dry.
