Fresh air is hard to come by in smog-filled metropolitan areas. Especially in the summer months, many people find solace through filtered air conditioning at home. But all it really takes to get fresh air indoors is to grow the right plants.
Kamal Meattle is an environmental activist who led a project to create India's healthiest building. He realized that clean ambient air at home is completely possible, with the help of the right plants.
Trees and plants are usually full of harmful pollutants because they absorb them through minuscule pores on the surface of their leaves. With Meattle's new system, particulate matter is siphoned and the plants work together to absorb carbon dioxide and emit oxygen. The three plants together can get rid of up to 87 percent of indoor air pollutants within 24 hours.
The three plants in the system are Areca Palm, Mother in Law's Tongue and the Money Plant. Areca Palm is great for dry offices, as it transpires up to a full liter of water a day. It also absorbs particulate matter, which often lead to heart disease or asthma. Mother in Law's Tongue emits oxygen through the night (most only do so during the day), and can absorb nitrogen oxide and fossil fuel. The Money Plant absorbs formaldehyde and benzene (found in car exhausts), which can cause drowsiness and headaches.
