What Are Air Purifying Plants?

The study conducted by NASA in 1989 showed that indoor plants that they were experimenting on have the capability to neutralize common air pollutants such as trichloroethylene, formaldehyde, benzene, xylene, and ammonia. Viewed in this manner, air purifying plants are plants that have the capability to remove air pollutants in the air and make the air more breathable.

It’s important that you know the sources and effects of common air pollutants.

Before we move on, it’s important that you know the sources and effects of common air pollutants such as trichloroethylene, formaldehyde, benzene, xylene, and ammonia. To start, trichloroethylene comes from printer inks, paints, and varnishes. Dizziness, nausea, and headache are some health problems caused by trichloroethylene.

Formaldehyde is an air pollutant that comes from commercial materials such as facial tissues, plywood paneling, synthetic fibers, wax bags, and paper bags. This pollutant has high concentrations in industrial and commercial areas. Health problems associated with it are irritation of the throat, nose, and mouth. Sometimes, it may also cause swelling of the larynx and lungs in severe cases.

Plastics, fibers, lubricants drugs, and pesticides are common sources of benzene. This may also come from vehicle exhausts, tobacco smoke, and paint. Factories, farms, and roads have high concentrations of this air pollutant. Regular exposure to benzene results in eye irritation, drowsiness, an increase in heart rate and in severe cases unconsciousness.

Xylene mostly comes from leather and paint industries. Health problems associated with this are irritation to mouth and throat, dizziness, headache, heart problems, liver damage, and coma. Last is ammonia. this is an air pollutant that comes from window cleaners, floor waxes, and fertilizers. Complications caused by ammonia are eye irritation, coughing, and sore throat.

Now that you know the meaning of air-purifying plants and what pollutants that they neutralize, it’s time that we talk about how they do their magic!

What Do Air Purifying Plants Do?

The main function of air-purifying plants is to make cleaner air by removing pollutants present in it. Air purifying plants start the process of cleaning the air by absorbing pollutants present on it into their leaves. After this, the air-purifying plants transfer the air pollutant absorbed by their leaves to their roots where microbes found underneath the ground disintegrate them. Those that cannot be disintegrated by the microbes are broken down by the plant itself.

Why do microbes disintegrate pollutants? The reason is simple, microbes that live in the roots of air-purifying plants feed air pollutants to survive. Also, plants need such pollutants such as ammonia and benzene for healthy growth.

Do Plants For Cleaning Air Really Work?

There are various studies that provide evidence about the effectivity of indoor plants for cleansing air. I cannot prove to you the effectivity of indoor plants using my own experience since I am no scientist. This is the reason why I will secure help from various studies conducted by reputable researchers to answer your question.

A study published in the Journal of Atmospheric Environment (2011) shows that four varieties of air-purifying plants – common house ivy, C.marifolium, dracaena compacta, and Epipremnum aureum- help to decrease the presence of formaldehyde on air within an enclosed space by 81%-96% per day per 1 plant. Such a decrease of formaldehyde brought only by a single plant is important to consider.

The research conducted by Peter Igra and associated states that S.podyphyllum may be utilized by cities to promote environment-friendly initiatives that promote cleaner air. S. podophyllum is claimed to decrease CO2 and benzene present in the air by 45%.

Research conducted by Bill Wolverton and many others in 1989 showed that the roots leaves, microbes and soil associated with plants have the ability to neutralize air pollutants coming from smoke, organic solvents, cigarette, and many others. This research, funded by NASA, further claim that plants neutralize such air pollutants to convert them into tissues, This study means a lot since it tells us that what seems harmful for us humans are beneficial to plants instead.

All the studies that I’ve discussed here are definite proof that plants for cleaning air work. If you’re eager to know the top 10 best NASA air purifying plants you need at home, then proceed with me unto the next section below.
