Spider plant (Chlorophytum comosum)
Even if you tend to neglect houseplants, you’ll have a hard time killing this resilient plant. With lots of rich foliage and tiny white flowers, the spider plant battles benzene, formaldehyde, carbon monoxide and xylene, a solvent used in the leather, rubber and printing industries. As an added bonus, this plant is also considered a safe houseplant if you have pets in the house. (Find more houseplants that are safe for pets.)
Also known as airplane plants, spider plants are also easy to regrow. Just cut off one of the "spiders" and place it in a pot. Spider plants are incredibly easy to grow, but thrive in cool-to-average home temperatures and prefer dry soil. Bright indirect sunlight keeps them growing best, reports Kansas State University.
