One of the easiest and prettiest ways to clean the air in your home is to utilize houseplants. Studies have shown putting one average houseplant (those that come in 6-inch pots) per 100 square feet of your home can remove up to 87 percent of indoor air pollutants. The key is to place the plants where they have access to sunlight and are in the most-visited rooms, like the office, living room or bedroom. If you have trouble keeping plants alive, look for houseplants marked “plants of steel” at the nursery. These are plants that can thrive on low light, low humidity and even if you forget to water them from time to time.
