As if I didn't need any more reason to adore peace lilies (Spathiphyllum), these gorgeous indoor blooms are officially one of the best houseplants for purifying the air in your home.
Not only is peace lily care easy, but these plants help remove harmful toxins in the air, all while adorning interiors with elegant white flowers. They were even named in a NASA air-cleaning indoor plants study as one of the best for leaving rooms feeling more fresh.
But, how does it work? Here, I explore more about how peace lilies purify the air and how to take advantage of it in the home.
How Do Peace Lilies Purify the Air?
'Peace lily is considered a natural air purifier as it has been proven to remove toxic materials such as benzene and formaldehyde from the air, thus, creating a healthier environment,' says plant expert Lee Miller.
In 1989, NASA released a game-changing report for indoor gardens. It revealed the houseplants that are most effective for removing toxins from the air, and peace lily was in the mix.
As Lee notes, the NASA clean air study found that the plants tested (including peace lily) significantly reduced the amount of benzene and formaldehyde – common indoor pollutants – in particular.
This occurs through a process called phytoremediation where the plant absorbs toxins through its leaf pores (or stomata). The toxins are then transported to the roots where microbial activity breaks them down.
'Plant roots and their associated microorganisms are the major pathway for chemical removal,' reads the NASA clean air study.
At the same time, peace lilies transpire, releasing moisture and oxygen into the air in exchange.
The fact peace lily has such luscious foliage makes it one of the most effective in this process, alongside ficus plants and ivy (also mentioned in the NASA report).
This peace lily measures 14-24 inches tall when delivered. It comes in a white ceramic planter.

This Lowe's peace lily is 24 inches tall at time of arrival. It comes in a nursery pot ready for repotting into a planter.
How to Use Peace Lilies to Purify the Air
You can take advantage of the fact peace lilies purify the air by placing a peace lily carefully.
For example, it can make a great bedroom plant for clean air that improves better sleep, and likewise works well as a bathroom plant to keep this space feel fresh and relaxing. Plus, the extra humidity in this room will keep this moisture-loving plant happy.
Another trick to make the most of the fact peace lilies purify the air is encouraging strong foliage growth.
This includes fertilizing your peace lily with a balanced NPK plant fertilizer to supply all the essential plant nutrients.
Nitrogen will encourage foliage growth, phosphorus encourages blooms, and potassium will improve plant processes, aiding toxin movement to roots where they're broken down.
This peace lily fertilizer from Amazon is a good choice, specially formulated to support all of these needs.
Make sure to also clean houseplant leaves to remove dust, ensuring pores aren't blocked and can absorb toxins effectively. I find microfiber houseplant dusting gloves (like these from Amazon) work well.
