When we bring furniture, carpets, inks, and dyes into our homes, we often unwittingly introduce toxins into the air. If left unabated, these toxins can cause long-term issues such as respiratory ailments, allergies, and headaches. The best air purifying indoor plants can help.

Not all houseplants are ideal for purifying indoor air. But these houseplants that have been found to effectively improve indoor air quality. Plus, these 10 houseplants help you to create a healthier home with minimal effort.

 

Common Indoor Air Pollutants

Toxins in our furniture, in building supplies, and products we use can accumulate in our environment reducing indoor air quality in our homes and offices. In 1989, NASA conducted its renowned Clean Air Study. This study examined common indoor air pollutants and the houseplants best able to naturally remove those contaminants from indoor air.

The results of that study found that there are five toxins commonly found in homes. Those toxins can have serious health effects over time, depending on exposure rate, length of exposure and other factors. Those most common indoor air pollutants include:

  • Benzene. Found in plastics, resins, dyes, synthetic fibers and more. Benzene can cause dizziness, increased heart rate, mental confusion, frequent headaches, and unconsciousness in high doses.
  • Xylene. Tobacco smoke, car exhaust and products produced by the paint and leather industries all can contain xylene. In high doses, xylene has been linked to serious heart issues, liver and kidney toxicity, and comas.
  • Formaldehyde. Products like paper bags, face tissues, paper towels, and plywood paneling all can contain formaldehyde. Exposure to this chemical can cause serious consequences, such as nose and mouth irritation and swelling of the lungs.
  • Trichloroethylene, Most often found in building supplies, such as paints, lacquers, adhesives, and varnishes. High concentrations of trichloroethylene have been linked to headaches, dizziness, vomiting and even comas.
  • Ammonia. Found in some window cleaners, fertilizers, and floor waxes, ammonia can cause coughing, sore throats and eye irritation.

 

Luckily for us, NASA also determined that some common are ideal natural purifiers to add to your home. These plants are houseplants readily available for purchase at nurseries and garden centers. According to NASA, a single plant can purify the air in a 100 square foot space quite well. But add more plants to your rooms and they clean your air that much more efficiently.
