NASA has been doing researches on ways to cleanse the air so that future space stations can become fit for human habitation for longer periods of time. Through the research made, it has been discovered that many common houseplants eliminate significant amount of harmful gases – such as benzene and formaldehyde – from the air through photosynthesis. The plants absorb the pollutants and render them harmless in the soil.
This is especially useful for those who live and work in newly constructed buildings, which are tightly sealed to conserve energy but trap pollutants indoors consequently. As recommended by NASA researchers, a minimum of two plants per 100 square feet should be used indoors, whether inside home or in the office. You don’t even need to have a green thumb to have these useful, popular and low-maintenance indoor plants.
Dracaenas are slow-growing plants that can retain their foliage for long periods of time. They can be planted in regular potting mix with constantly moist soil, but don’t let the pot sit in water. These plants love bright, indirect sunlight, low humidity, and warm temperatures.
It is one of the favorite house plants because they can grow better than most plants even under adverse conditions. They are best kept in warm, moderately moist areas and away from direct sunlight.
This plant looks similar to the philodendron but it can be distinguished by the ridges on the stems. Because these plants are climbers, they will look nice in a hanging basket. They grow best in warm temperatures, bright but indirect sunlight, and low humidity.
Chinese evergreen plants can tolerate various indoor settings and flourish for years with minimal care. If kept in a shadowless area, such as a north-facing window, with the soil kept barely moist, they can stay with you for many years.
The weeping fig, or ficus benjamina, grows well under normal household conditions. The leaves drop in cold temperature. Keep the plant’s roots crowded in a small pot and frequently wipe the leaves with a wet cloth.
