10 Best Nasa Approved Air Purifying Plants to Reduce Air Pollution

air purifying plants

There is a possibility that you are living in a sick house without knowing it. This is because we have three to five times more pollutants indoors than outside. 

A lot of things you use on a daily basis can cause headaches, allergies, breathing problems, and sore throats, like xylene (in paint and lacquers), benzene (in furniture wax and insect repellants), formaldehyde (in upholstery) and trichloroethylene (in cleaners and adhesives).

Therefore, a NASA study looked into simple, yet effective methods for detoxifying indoor air. In a study, it was revealed that some house plants have natural air purifying powers and can be kept at home. Would you like to know which air purifying plant NASA approved? Keep reading to find out.

How Do Air Purifying Plants Work

The first thing we need to understand is how plants purify the air. Plants purify air through photosynthesis, as you probably know. 

We breathe in oxygen and exhale carbon dioxide, but plants do the opposite. Additionally, the function of plants is to absorb light, carbon dioxide, and water, and to produce sugar. During this chemical process, oxygen is produced as a byproduct. 

Now, a second concept to understand is phytoremediation. When a plant mitigates pollution in the soil, air, or water, it is called phytoremediation. 

Moreover, NASA’s research shows that air-purifying plants can absorb other gases besides carbon dioxide, including volatile organic compounds (VOCs). Many indoor VOCs, including benzene, found in plastics, fabrics, pesticides, and cigarette smoke, are also eliminated by plants.

As air purifying plants transpire, phytochemicals and water vapor are released, causing air to move. It’s easy for plants to pull toxins out of the air as they transpire. Additionally, to absorb pollutants from the air, leaves have microscopic openings called stomata.

All of these processes result in a reduction in air pollution. However, air purifying plants can offer you much more than that. Take a look at the amazing benefits of air purifying plants below.

Benefits of Air Purifying Plants

Benefits of Air Purifying Plants

NASA Clean Air studies have shown that indoor plants can reduce airborne contaminants such as cigarette smoke, dust, germs, and chemicals.

Also, the benefits of air-purifying plants go beyond converting carbon dioxide into oxygen. Here are some:

  1. By detoxifying the air, plants reduce allergy symptoms like itching, runny noses, eye irritation, and breathing difficulties.
  2. You may feel more relaxed and calm when you are constantly surrounded by plants, which can reduce stress and anxiety. 
  3. In addition to improving concentration and memory, plants have calming effects.
  1. When certain air purifying plants are present at home, volatile organic compounds (VOCs) from home building and maintenance products are minimized. Some types of cancer are linked to VOCs due to their long-term effects, including chronic headaches, nausea, irritation, kidney damage, and nervous system damage.
  2. Air purifying plants can improve your sleep quality because they help purify the air you breathe.
  3. When people suffer from depression, trauma, and dementia, being around plants helps them recover.
  1. Aside from its physical and mental benefits, air purifying plants also enhance the aesthetics of a place.

Aren’t those great benefits of air purifying plants? Yet, it can be difficult to care for plants, especially if you lack a green thumb. Worry not! Listed below are the 10 best air purifying plants you can grow at home easily.
