14 Houseplants that Will Naturally Purify the Air in Your Home

These days, it’s an unfortunate fact of life that the vast majority of us are living in moderately to highly polluted environments. Outdoor pollution and smog, particularly in dense urban centres, are a major concern, but many people don’t realize that the air inside their homes can also be laden with chemicals.

Indoor air quality can be quite poor due to things like paints, furniture, mold, smoking, oven exhaust, commercial cotton products, cleaning products, hair sprays, and so much more- over time it can really add up! In fact, according to a study conducted by the Environmental Protection Agency, some pollutants are often two to five times higher indoors than outdoors! The same study found that most people spend up to 90% of their time indoors, so what’s going on inside our homes really does matter.

Indoor pollutants have been tied to everything from headaches, nausea, and irritation of eyes, nose, and throat, to more serious implications including respiratory disease and cancer. While everyone is at risk, those with asthma, allergies, or lung disease are especially at risk.

The following are some of the most common chemicals found in our indoor air.

Trichloroethylene: Found in paints, varnishes, and pain removers, it’s been associated with dizziness, nausea, headaches, vomiting, and drowsiness.

Formaldehyde: Found in paper bags, waxed bags, facial tissue, paper towels, and more, formaldehyde can cause irritation to the throat, mouth, and nose, and even swelling of the larynx and lungs.

Benzene: Plastics, synthetic fibers, detergents, pesticides, tobacco smoke, and paints are just some of the many items containing benzene, which can cause drowsiness, dizziness, headaches, and irritation to eyes.

Xylene: Found in rubber, leather, tobacco smoke, and car exhaust, xylene has been known to cause irritation to mouth and throat, dizziness, headaches, heart problems, and even liver and kidney damage.

Ammonia: Ammonia is found in fertilizers and some household cleaners and can cause coughing and irritation to the throat, nose, and respiratory tract.

Okay, that was a lot of daunting information, but don’t worry, this post isn’t all doom and gloom! The good news? There is a very simple, completely natural, and décor-friendly way to purify you air.

In 1989, NASA conducted the Clean Air Study, which looked at the effectiveness of different houseplants for filtering toxins and pollutants out of the air. The findings have stood the test of time and continue to be a great resource today! The study recommended having one house plant per 100 sq. feet in your home. Before choosing a plant for your home, please note that some are toxic to pets, so do some research before you purchase!
