Indoor Plants For Cleaner Air And Health

House plants remove pollutants and toxins. Imagine using indoor plants for cleaner air inside your home! And improving your own health at the same time!

Wanna know something that a lot of people don’t think to do? Bring the plants inside!

You spend a lot of time indoors.

Time in your house. In your office. In your car. Inside shopping.

Houseplants Can Clean The Air Inside

Inside air can carry pollutants and toxins. Studies show that having indoor plants can help remove pollutants and toxins from the air, making it healthier.

Plants can naturally absorb carbon dioxide and other harmful compounds from the air, acting as living air purifiers, absorbing chemical pollutants. And not only do they look good, but plants also produce oxygen and naturally add humidity to the air.

Just think, healthier air to breathe can help make you healthier too!

Plants with their lovely foliage and flowers are a welcome (and inexpensive, score!) addition to the interior of any home. But, there are more benefits to houseplants than just their good looks.

Indoor houseplants have been shown to reduce stress and lift moods. Some studies even suggest that plants help improve workplace performance productivity when people have them grow within their workspace.

Want proof? Need hard and fast numbers to convince you?

We’ve got that too. Let’s look at some of the studies to see how indoor plants can help purify the air and remove toxins.

What is Indoor Air Quality?

A survey by the U.S. Environmental Agency (EPA) found that Americans spend 87 percent of their time indoors. Wow, 87%!

Since we spend so much time indoors, good indoor air quality is vital for good health!

The EPA also found that indoor levels of pollutants might be as much as 100 times the levels found outside!

Many factors contribute to indoor air quality. This is due to all of the toxins released into the air from cleaning chemicals, dust and dirt, cooking fumes, and all of the other simple daily activities that take place in the home on a daily basis.

The most common toxins in your home are ammonia, formaldehyde, and benzene. These indoor toxins can come from furniture, carpets, building materials, cleaning products, personal care products, and improper maintenance of heating and air conditioning systems.

The pollutants become trapped by closed ventilation systems and can cause respiratory and allergic reactions that are now known as Sick Building Syndrome.

And you know what the experts recommend for improving indoor air quality? Indoor house plants!

In 1996, a six-month study was published that compared a room filled with plants with a room that had no plants.

The room without plants had a 50% higher level of airborne microbes and bacteria.

It proved that large quantities of house plants can be used to increase humidity levels and suppress harmful bacteria while reducing air polluting substances. And perhaps indoor plants purify the air!

Do You Know What NASA Plants Are?

How pure is the air you breathe? Perhaps you can create your own fresh air! WITH PLANTS! Plants remove pollutants and toxins from the air.

NASA conducted a Clean Air Study trying to find solutions for individuals who were having health issues caused by spending a large amount of time indoors.

They published the results in 1989 (Interior Landscape Plants for Indoor Air Pollution Abatement) and recommended using plants to help remove contaminants from the air.

If you want to learn more about the NASA Clean Air Study, here’s a link to the Wikipedia article that is easier to read than the NASA Clean Air Study document.

Also, while working with NASA to develop a method for creating a breathable environment for a NASA lunar habitat, Dr. B.C. Wolverton discovered that house plants are the best filters of the common pollutants.

He wrote a book How to Grow Fresh Air: 50 House Plants that Purify Your Home or Office which lists 50 indoor plants that can help remove contaminants and pollutants.

In his book, he shows us how to grow and nurture these 50 plants. He rates each one for its effectiveness in removing indoor toxins, as well as its ease of growth and maintenance.

Today, NASA even adds plants to its international space station to help control air quality.

So, just think what a few plants can do to improve your home or office air quality!

The Plants

While most leafy plants can purify indoor air, some are better than others at removing volatile organic compounds (VOCs) like benzene and formaldehyde.

VOCs may have short- and long-term adverse health effects.

Here are a few of the plants that were studied in the NASA Clean Air Study.

They are proven to help improve your indoor air quality and remove pollutants, toxins, and VOCs from the air. And the plus? Plus, they are all very low-maintenance and easy-care!
