Breathing Fresh: NASA’s Top 12 Air-Purifying Plants for Cleaner Indoor Spaces

In 1989, the National Aeronautics and Space Administration (NASA) partnered with the Associated Landscape Contractors of America (ALCA) to conduct a Clean Air Study. Led by Dr. B. C. Wolverton, the study provided a comprehensive list of plants that are highly effective at purifying indoor air. The research demonstrated that plants have the ability to filter pollutants such as benzene, ammonia, and formaldehyde, which helps mitigate the effects of Sick Building Syndrome. Certain tropical houseplants were found to be particularly efficient in removing formaldehyde, trichloroethane, benzene, and other harmful substances from the air, replacing them with oxygen. According to the report, it is recommended to have at least one plant for every hundred square feet of indoor space, be it at home or in the office.

Common Indoor Pollutants

Trichloroethylene, formaldehyde, benzene, xylene, ammonia, nitrogen dioxide (NO2), sulfur dioxide (SO2), and suspended particulate matter (SPM) are harmful substances found in various products and environments.

• Trichloroethylene, present in inks and pa2ints, can lead to symptoms such as dizziness and coma.
• Benzene, used in plastics and tobacco smoke, may result in drowsiness and unconsciousness.
• Formaldehyde, commonly found in paper products and fabrics, can cause irritation and swelling in the respiratory system.
• Ammonia, found in cleaning products, can cause eye irritation and sore throat.
• Xylene, present in rubber and vehicle exhaust, can lead to liver and kidney damage.
• NO2 and SO2, emitted by vehicles and factories, can harm the cardiovascular and respiratory systems.
• SPM, small particles in the air, can irritate the eyes and respiratory tract and contribute to long-term health issues like asthma and cardiovascular problems.

Portable smart farm concept lets you plant veggies anywhere inside your home

Indoor gardening became quite a fad in recent years as people tried to cope with being stuck indoors for days at a time. But while the majority of this trend revolved around succulents and decorative plants that are easy to grow, it also presented an opportunity to start a trend of growing consumable greens indoors as well. Indoor planters try to offer this kind of convenience, but most of them tend to be large appliances no smaller than cabinets or shelves. Smaller households that want to grow a small number of verbs and vegetables might feel left out, but this concept tries to offer those same conveniences and smart features in a more portable design that you can literally put anywhere in your house, apartment, or room.

Designers: Deokhee Jeong, Yubin Choi, Youngnam Lee, Sewoom Hahn

Smart planters may sound simple but the amount of calculations they have to make can be quite complicated. They have to make sure that the plants are not just getting the right amount of LED light each day, they also have to distribute the right amount of water that the plants need, not less and definitely not more either. It’s no surprise, then, that many indoor planter appliances can be quite big, taking into account not only the water container and soil pots but also the electronics and mechanisms needed to make it work.

The POT version of the BalconyFarm planter condenses all those those into a farm that can fit on a small table or even a wide window sill. The box-like device has eight circular containers that can hold the potted plants, but in reality only six of these can be used at the same time, at least if gardening indoors. One spot is where you’ll set up the lamp, while the other circle is reserved for the water container. These two can be placed in any of the eight holes, making the proper arrangement of herbs and vegetables even easier.

Despite the petite size, the BalconyFarm POT has the same smart features as its bigger sibling. That means it knows exactly how to to distribute the water to plants, no matter which spot you place the water container on. Admittedly, there are a few disadvantages, though, like the uneven distribution of light from a single lamp and the lack of ventilation around the plants. On the flip side, you place this planter anywhere, so you can use the growing plants as a decorative centerpiece for your table or desk as well.
