Now that the weather is colder and we’re keeping doors and windows closed, indoor air quality can really suffer. Instead of using chemical air fresheners, try house plants to improve indoor air.
According to a two-year study by the National Aeronautics and Space Administration (NASA), many indoor plants absorb air pollutants through their leaves and roots and convert them into breathable air. Within 24 hours, some plants can remove up to 87 percent of toxic indoor air.
Depending on the species, one plant can provide effective cleaning for every 100 square feet of space. For example, between 15 and 20 golden pothos and spider plants can refresh the air in an average 1,800 square-foot home.
Plants work equally well in homes, offices, and factories, as long as their requirements for sunlight, water, and soil are met. Here are 15 plants that can really help improve indoor air quality.
