10 Best Air Purifying Plants NASA-approved

Remove Indoor Toxins From Your Home and Office

Did you know that indoor air pollution is one of the top environmental risks to your health? After having some issues with what I thought must be allergies that just never went away, I introduced some NASA approved air purifying plants to my home. After not too long, my “allergy” issues started to disappear. A few carefully chosen plants (one for every 100 square feet is ideal), even for me, a total novice houseplant gardner, made quite a difference in my life. Who knew that NASA, an organization that achieved one of human-kinds greatest feats, would have such a great, but simple solution to indoor earth-bound, air pollution?

 

How is Indoor Air Quality Affected?

In this modern world, we live in enclosed spaces, oftentimes sealed up by high-quality windows, weather stripping, and high-efficiency furnaces and air conditioners. Combine this well-sealed environment with dust, furnishings, cleaning products, artificial air fresheners, and synthetic building materials, our homes can emit a wide variety of toxins and chemicals into our indoor air. Things like ammonia, benzene, and formaldehyde can really do a number on our bodies, even in small amounts. These chemicals can lead to something called “sick building syndrome,” which can be the cause of headaches, eye, ear and nose irritation, dizziness, and nausea.

NASA Study: What’s in our air?

NASA ran a clean air study to research the ways they could clean the air on space stations. They were looking for ways to use photosynthesis, the process that plants go through to “ingest” carbon-dioxide, and “breathe out” oxygen, to keep the air fresh and comfortable in a tightly sealed environment. What they learned not only helps astronauts stay healthy in space, but it revealed that plants don’t only clean carbon-dioxide out of the air in space, they also remove other things from our environments and purify the air.

After further study, NASA revealed that they had discovered plants also cleanse the air here on Earth in our indoor environments. Houseplants can remove other toxic chemicals from the air. NASA found that there are five main chemicals these plants are able to cleanse the air of; ammonia, xylene, trichloroethylene, formaldehyde, and benzene. Each of these chemicals is brought, by us, into our homes in many surprising ways.

  • Ammonia, likely the most familiar of these chemicals to most of us, is in window cleaner, multipurpose cleaners, toilet bowl cleaners, oven and drain cleaners, and the like.
  • Xylene is mainly found in paint and furniture stains and waxes.
  • Trichloroethylene is found in household cleaners, glues, carpet spot removers, and paint.
  • Formaldehyde makes its way into our indoor spaces via furniture, bed sheets, mattresses, air fresheners, and even clothing.
  • Benzene comes indoors in inks, rubber, paint, and glue.

 

How Do Plants Remove Toxins from the Air?

It turns out, those lowly houseplants are absorbing and processing some other harmful and unpleasant chemicals when they absorb and process carbon-dioxide. NASA discovered the plants are helping us out even more than we thought by taking in many of the compounds and chemicals we’ve added to our indoor air. Not only that, but NASA learned that even some of the microbes in the potting soil are working double-duty. The soil is keeping the plant happy and fed and alive, while at the same time removing benzene from the air around it.


Toxicity to Pets

Before running to your nearest gardening center or farmer’s market of choice, keep in mind that we are talking about indoor plants. And indoor plants can be harmful to your cats and dogs in ways they aren’t harmful to you and me. The ASPCA has an in-depth listing of plants that are toxic to dogs and cats. Always check there before deciding what plants to add to your home (indoors or out).

#6 Ficus or Weeping Fig

Ficus is a tree. When grown indoors it can be anywhere from two to ten feet tall.

This one is a great wintertime air cleaner. It likes indirect light and you can let the soil dry out between waterings.

More Uses and Benefits to Houseplants

Not only do these, and other, houseplants naturally and effectively clean indoor air, but they can also provide other benefits. Such as in the case of Aloe Vera’s wound-healing properties, houseplants can be used for other things. Just the very act of having living plants in your environment can make you healthier. Studies have shown that plants even have a psychological effect on us; being around plants, for example, can cause people to recover from illnesses faster. Keeping plants around also helps reduce stress.

Summary

I couldn’t imagine going back to having a house without houseplants. Having brought even just a little bit of nature inside my home has made life better by cleaning my air and making it, in general, a more cheerful and welcoming space. Stress levels drop and make everyone feel just a little closer to nature and having an Aloe Vera in the kitchen helps when I’m looking to soothe an accidental burn while working at the stovetop. Check into going this route with your indoor space. But don’t just take my word for it – NASA thinks it’s a good idea too!
