The Peperomia plant is an easy-going choice that’s great for beginner houseplant enthusiasts. They are extremely drought tolerant and require minimal effort. Their spectacular thick, fleshy leaves boast of lovely color and add freshness to their environment. One unique aspect of Peperomia is that its foliage purifies the air, according to NASA’s research. The supplementary Wolverton’s Clean Air study shows that Peperomia reduces the levels of formaldehyde indoors by 47% and that’s good to know because a significant portion of indoor air is made up of the substance. The easy-to-maintain plant should be situated in medium to bright filtered light and in soil that is chunky and loose. Only water it when the soil is dry, and you're good to go!
