Best Indoor Air Purifying Plants Recommended by NASA-Chinese Evergreen

About Chinese Evergreen:

Chinese evergreen (Aglaonema), is one of the best plants for beginners (or folks too busy to keep most houseplants alive). This sturdy plant is wonderfully easy to grow; it tolerates just about every indoor condition. While it’s one of the toughest plants, it’s also beautiful. Most varieties have rich green leaves attractively patterned with silver. It also has cute, calla-lily-like blooms in spots where it gets enough light. 

Chinese evergreen, when it’s young, is small enough to fit on desks, tabletops, and other surfaces. It’s a slow-growing plant, so you can enjoy it without worrying if it will grow out of bounds. Older, larger plants are suited to growing on the floor — in corners, next to furniture, or as an accent piece along a wall. The silvery tones in Chinese evergreen’s leaves let you have some fun choosing pots; the neutral color works with just about every decor color palette and style.

Southern Living actually calls the Chinese evergreen “the easiest houseplant” because these plants thrive in low light and will grow in places where other plants won’t grow. Because they are tropicals, they like humid air. If your air is too try, tips might turn brown, so you might want to mist the leaves occasionally

Health Benefits of Chinese Evergreen:

Indoor air pollution

Living in an energy efficient, modern building can have unintended side effects. One of these side effects is less air flow. Lack of air flow allows for indoor air pollution to build up and cause health issues like asthma or sick building syndrome.

In fact, modern furnishings, synthetic building materials, and even your own carpet may carry more chemicals than expected. These chemicals can make up to 90 percent of indoor air pollution.

Plants to the rescue

In 1989, NASA discovered that houseplants can absorb harmful toxins from the air, especially in enclosed spaces with little air flow. This study has been the basis for newer studies about indoor plants like Chinese Evergreen and their air cleaning abilities. While plants have less horse power than air purifiers, they’re more natural, cost effective, and therapeutic.

Chinese Evergreen Plants are also known to:

  • increase mood and productivity
  • enhance concentration and memory
  • reduce stress and fatigue

NASA recommends two or three plants in 8 to 10-inch pots for every 100 square feet. Some plants are better at removing certain chemicals than others. Household chemicals come from objects and materials like:

  • carpets
  • glues
  • ovens
  • cleaning solutions
  • synthetic materials such as plastic, fiber, and rubber

You’ll benefit the most when you include a variety of plants in a room.

Eliminates: benzene, carbon monoxide, formaldehyde, trichloroethylene, and more

Chinese Evergreen Care:


Chinese Evergreen plants are one of the few houseplants with light green and gray in the leaves that can grow in low light. The newer varieties of Chinese Evergreen houseplants that have bright red, pink, yellow, and orange in the leaves require medium to bright light. Never place a Chinese Evergreen in the direct sun


Allow the top 25-30% of the soil of a Chinese Evergreen houseplant to dry out before watering. When the soil of a Chinese Evergreen Plant stays too wet for a long period of time, the stalks rot and die. If the soil of a Chinese Evergreen Plant gets too dry or too wet, yellow leaves develop


Chinese Evergreen houseplants do not need much fertilizer. Feed a Chinese Evergreen Plant every other month with a basic houseplant food at 1/4 the recommended strength when the plant is actively growing.


Temperatures below 50 degrees can damage the leaves of Chinese Evergreen houseplants. Keep Chinese Evergreen Plants out of cold winter drafts and away from air conditioners.


Chinese Evergreen plants prefer regular household humidity or higher if possible.


If your Chinese Evergreen houseplant produces flowers, immediately cut them off. The flowers are not very attractive and use energy that the plant needs to produce its beautiful leaves.


A Chinese Evergreen plant is susceptible to the plant pests Mealy Bugsscale, and Aphids. Thegreen solution, sprayed on both sides of the leaves usually solves the problem. (recipe for green solution in the Glossary ).


In high humidity, the large leaves of a Chinese Evergreen plant may develop bacterial diseases such as Leaf Spot.


The best soil for Chinese Evergreen houseplants is a basic, well-aerated houseplant potting soil that drains quickly


Keep a Chinese Evergreen Plant in a small pot so the soil can dry out quickly and the roots are not constantly wet.


If a Chinese Evergreen plant becomes thin and leggy, prune the stems a few inches above the soil line. The plant will send out new growth at the bottom of the stem and along the length of the stem.


Chinese Evergreen plants are propagated using stem cuttings and by plant division.


NASA lists the Chinese Evergreen Plant as one of the top 10 best houseplants to clean the air of harmful toxins.
