Snake Plants – An Indoor Plant that Aids Air Purification

If you are on a quest to decorate your living room or your bedroom, then getting an indoor plant should be part of your list. An indoor plant brightens the room’s mood, but some plants aid air purification. And in this post, I will be introducing one of these air purification plants called the Snake Plant.

What is a Variegated Snake Plant?

The variegated Snake plant or Snake Plant (Sansevieria Trifasciata) is an evergreen perennial plant native to tropical West Africa. It is commonly known as the Snake Plant and by its other names like Saint George’s sword, Mother-in-law’s tongue, or viper’s bowstring hemp. It has stiff leaves that grow vertically from a basal rosette. This plant’s leaves usually grow from 70 – 90 centimeters (28 – 35 in) long and 5 – 6 centimeters (2.0 – 2.4 in) wide.

The snake plant is one of the plants tested during the initial 1989 NASA Clean Air Study. The study was conducted by the  National Aeronautics and Space Administration (NASA) in association with the Associated Landscape Contractors of America (ALCA). It aims to seek ways to clean the air in space stations. 

Researchers from Naresuan University in Thailand conducted another study specifically for this plant. The study aimed to show that the snake plant can efficiently reduce carbon dioxide (CO2) levels. Indeed, they were able to decrease carbon dioxide levels in their experiments.

The plant can exchange oxygen and carbon dioxide using the Crassulacean Acid Metabolism process, which gives the plant the ability to withstand drought. It uses its stomata, the microscopic pores in the plant’s leaves, to exchange gases, and these only open at night to prevent water from evaporating. And, when these stomata open at night, stored oxygen is released. 

Aside from converting carbon dioxide into oxygen, the plant also absorbs/filters cancer-causing pollutants like benzene, formaldehyde, xylene, and toluene.

This particular plant is a trouble-free plant. It can tolerate lower light conditions so that you can place it in a shady area with no direct sunlight (indoor). Or, you can put it outdoors where it could also strive. It also does not require any pruning. Lastly, make sure to take note of the following when you have water these plants:

1. It does not require frequent watering.
2. Make sure not to overwater the plant. Check the soil if it is all dry before watering the plant.


To have a healthy body, one must eat healthy food and do exercise, but we also need to make sure that we have a healthy living space. A healthy living space needs to be clutter-free and clean, but it must have adequate ventilation and clean air.
