What do astronauts and your home have to do with each other? They both need clean air. NASA has conducted studies that show certain houseplants help to keep the air around them clean of toxins. They do this by absorbing the substances from the air and releasing oxygen. The toxins are then either used or released by the roots into the soil. Not all homes have a lot of windows or sunlight available, which means they need to choose air-cleaning plants that can tolerate low light.

Astronauts in space need clean air, just as we do in our homes.

Snake Plant

Sansevieria trifasciata, also known as snake plant, can live in low light and dry soil. It grows slowly. Its tall, stiff, upright leaves are pointed at the ends. The only condition to be careful about is avoiding over-watering, as this will cause root rot and kill your plant. Use well-draining potting soil mix to avoid having your plant's roots sitting in soggy soil. Give your snake plant fertilizer every month in the spring, summer and fall for best results. This plant will also help keep your air clean by removing toxins.

Spider Plant

The Chlorophytum comosum, or spider plant, has spider-leg-like leaves that grow out of the main base. It is a very easy-going plant that will tolerate low light and a variety of temperatures. The spider plant creates runners, off of which it grows baby plants that can be propagated by planting in soil. This plant enjoys being in a slightly small pot. Use a well-draining potting soil mix and keep the plant evenly watered, but not soggy. This plant will also help keep the air quality clean of formaldehyde in your home.

Heartleaf Philodendron

Philodendron scandens, or the heartleaf philodendron, can help the air quality in your home, and is easy to grow, and will also tolerate low light levels. Its leaves start out as bronze, but turn green and glossy. Pruning will keep your plant bushy, while leaving it to branch out results in long vines. The heartleaf philodendron is also slow growing and will not need repotting often. Treat it to a water mist every now and then to keep it thriving. Use a well-draining potting mix and fertilize in the spring, summer and fall months.
