With the rise in living standards, it has become increasingly popular for people to use green plants to decorate and enhance their living spaces. Recently, NASA scientists have discovered that many evergreen and flowering plants can effectively remove harmful chemicals from indoor air. The research also revealed that plants don't just rely on their leaves for this process; their roots and the bacteria in the soil also play a crucial role in filtering out toxins. According to Zhou Shuqin, an engineer at the Indoor Environmental Monitoring Center of the China Decoration Association, there are three types of plants that are particularly beneficial to have at home.
Plants that can absorb toxic chemicals
Several plants are known for their ability to clean the air by removing harmful substances. Aloe vera, spider plant, tiger-tailed orchid, leaf orchid, and monstera are natural air purifiers that help eliminate pollutants. Studies show that Sansevieria and Chrysanthemum can absorb over 80% of indoor toxins, with exceptional performance in removing formaldehyde. Aloe vera is especially effective, capable of absorbing up to 90% of formaldehyde in one cubic meter of air.
Other plants like ivy, cypress, chrysanthemum, kumquat, pomegranate, rose, camellia, and marigold can efficiently remove sulfur dioxide, chlorine, ether, ethylene, carbon monoxide, and nitrogen oxides.
Orchids, sweet-scented osmanthus, broccoli, mosaics, and red-backed osmanthus act as natural dust collectors, using their fine hairs to trap airborne particles and smoke.
Mosquito-repellent plants
As temperatures rise, plants that naturally repel mosquitoes have gained popularity. One such plant is Mosquito Net Vanilla, a genetically modified geranium from Australia. It is drought-resistant, grows quickly, and can live for 10 to 15 years with proper care. Its pleasant lemon scent helps keep mosquitoes away without any harmful effects on humans. The hotter the weather, the stronger the fragrance and the better the repellent effect. Testing shows that a plant over 30 cm tall can significantly reduce mosquitoes in a 10-square-meter room. Another option is pyrethrum, which contains pyrethrins and also repels insects.
Plants that can kill bacteria
Aromatic flowers like roses, osmanthus, violets, jasmine, lemons, carnations, lilies of the valley, and crepe myrtle release volatile oils that have strong antibacterial properties. Plants such as Lagerstroemia, jasmine, and lemons can kill bacteria like diphtheria and dysentery within five minutes. The fragrances from roses, carnations, lilies of the valley, violets, and osmanthus also inhibit the growth of tuberculosis, pneumococcus, and staphylococcus.
Cacti, native to arid regions, absorb carbon dioxide during the day and release oxygen at night, increasing the level of negative ions in the air. Other plants like Tiger Piran, Sansevieria, agave, brown hair palm, garam blue, sedum, pineapple, and others also help purify the air at night.
Climbing plants such as grapevines, morning glories, wisteria, and roses can be trained to grow along walls or structures, creating a green canopy that reduces solar radiation and lowers indoor temperatures.
Finally, plants like cloves, jasmine, roses, violets, and peppermint can promote relaxation, improve mood, aid sleep, and boost productivity. Adding these plants to your home not only enhances aesthetics but also contributes to a healthier and more comfortable living environment.
