I recently added three snake plants to my bedroom window sill. It’s been well documented that the air inside our homes is often polluted by chemicals from cleaning products, furniture, and from poor air circulation. Fortunately, a study by NASA reveals that some plants, such as these, are excellent at removing toxins from the air including formaldehyde, xylene, and toluene. Plants like peace lilys and chrysanthemums, go even father by also removing benzene, trichloroethylene, and ammonia.
I chose snake plants for my bedroom windows for a few reasons. In addition to being able to filter these chemicals out of the air we breathe, they are among a select group of plants that can theoretically help you sleep better. While most plants produce oxygen during the daytime, and release carbon dioxide at night, these do the opposite, creating oxygen after dark. Orchids also produce oxygen at night, so I plan to add one to my dresser. Bromeliads and aloe vera also produce oxygen at night, but in feng shui, sharp and spikey plants are said to be the wrong idea when trying to create a restful sleeping environment. They would work better in another part of the home or outdoors.
Snake plants do well indoors and should thrive by my windows since they only need partial sun. My windows face north, and have UV filtering / energy efficiency film, which carry a slight tint.
If we can remove harmful chemicals from the air we breathe inside our homes and offices, imagine what we could do for the planet if we devoted more outdoor space to air filtering plants, and less space to grassy lawns. All the more reason for us to protect the forests, deserts, and jungles.
As always, be sure you know what plants are toxic to house pets if you have a curious, or mischievous, creature living among you.
