Explain why indoor plants can help purify the air?

In short (click here for detailed version)

Indoor plants can help purify the air by absorbing pollutants present in the environment, such as formaldehyde and benzene, thanks to their natural filtration ability.

The role of photosynthesis in air purification

Plants perform photosynthesis, a magical process where they transform light into energy. They absorb carbon dioxide (CO2) and release oxygen in return. It's somewhat like their way of breathing. We produce CO2 all the time by breathing and with our cars. Too much CO2 is bad. Plants work hard for us, capturing this CO2 and producing healthy oxygen. So, in addition to making our space greener and more lively, they purify the air we breathe. Thanks to photosynthesis, they make the air in our homes cleaner and fresher. Less CO2, more oxygen, we breathe better.

Elimination of VOCs (Volatile Organic Compounds) by plants

Houseplants remove VOCs such as benzene, formaldehyde, and trichloroethylene by absorbing them through their leaves. These substances are often emitted by furniture, paints, or household products. Once absorbed, these VOCs are transported to the roots where specific microbes, in symbiosis with the plant, break down these substances into nutrients. In short, plants act as living sponges, absorbing air pollutants and using them to their advantage and ours. The result: cleaner air and reduced health risks.

Plants and the Regulation of Humidity

Houseplants help regulate humidity by releasing water vapor through a process called transpiration. Stomata, small openings on the leaves, allow for this evaporation. When the air is dry, plants release more moisture, making the air more comfortable. Large and leafy plants are particularly effective at this. This additional humidity can reduce respiratory issues, decrease skin dryness, and even protect wooden furniture from drying out. In short, having plants at home is like having a natural mini-humidifier that works continuously.

Roots and Their Role in Air Purification

The roots of indoor plants play a key role in air purification. They don't just absorb water and nutrients; they also capture toxins present in the soil. These are then transformed by microorganisms that live around the roots. It's a bit like these roots have their own built-in cleaning team. Some plants, like the pothos, are particularly skilled at this job. The raglouts floating in the air can penetrate the soil via the roots to be broken down there. It’s a continuous, simple, and effective biochemical process. And all this while the plant produces oxygen. A real winning combo.

The most effective indoor plant species

Some indoor plants are more effective than others at purifying the air. The Spathiphyllum, or peace lily, is an expert at removing VOCs like formaldehyde and benzene. The Sansevieria, also known as the snake plant, works around the clock to convert CO2 into oxygen. The Pothos is a powerhouse at filtering benzene, formaldehyde, toluene, and xylene. Aloe Vera not only soothes cuts and burns but also tackles formaldehyde. The Ficus elastica, or rubber plant, is a champion against toxins and mold. In short, these plants are not just decoration; they work hard to provide you with cleaner air.
