50 Air Purifying House Plants by NASA

Air-purifying house plants by NASA that can help you improve the quality of air in your home. These air purifying indoor plants remove toxins, volatile organic compounds (VOCs) from any space in your home.  It’s important to note that we don’t know how many plants we need in a space to effectively clean the air. Most people go for quite a few between 5 and 20 depending on the square footage of your house.

It’s safe to assume that the more air purifying plants you have the more toxins they remove. Air circulation also plays a large part in the removal of the VOCs. Make sure you keep your windows open as much as possible to allow some sort of transfer of outdoor air inside. This list contains plants listed by NASA as well as others listed by other researchers.

How Air Purifying Plants Remove Toxins

The plants get rid of the toxins in the air by either absorbing them, excreting them or degrading them.  They take the toxins and absorb them through their foliage through the stomata and cuticles. The toxins move into the plant’s system where they are absorbed, excreted, or degraded.

The plant root system and the soil system also have microorganisms that break down the toxins. The soil can also bind the toxins making them immobile and not able to move freely in the air.
