2. Snake Plant

The Snake Plant is extremely effective at absorbing harsh chemicals such as benzene, formaldehyde, and carbon monoxide — all of these chemicals can cause nose and throat irritation —  and other harsh pollutants found in indoor air. It also produces oxygen while absorbing CO2 at night, and has been shown to help with airborne allergies.

A study made at Naresuan University, Phitsanulok, Thailand confirms that the snake plant can absorb CO2 in a closed system at 0.49 ppm/m3.

Also known as Mother-in-Law’s Tongue in different parts of the world, this indoor plant is very easy to take care of. They grow in both low and full light conditions and don’t need a lot of water. As a result, the snake plant is definitely ideal for beginners.
