Monstera plants do clean the air, but not in the dramatic, Instagram-perfect way you might expect.
If you’ve ever typed “do monstera plants clean the air” into a search bar, you’ve probably seen conflicting answers.
The true answer is yes, monstera plants clean the air by absorbing certain indoor pollutants through their leaves.
However, their air-purifying power is modest, especially when compared to some smaller, less glamorous houseplants.
That doesn’t mean your monstera is useless, though, and in this post we’re going to explore exactly how monstera plants help clean the air in your home.
By the end, you’ll know what they remove, why they’re not miracle workers, and how to get the most out of them.
Let’s get started.
Why Monstera Plants Can Clean The Air
1. The NASA Clean Air Study Foundation
The idea that monstera plants can clean the air became popular after NASA’s landmark Clean Air Study in 1989.
That research was designed to figure out which houseplants could remove volatile organic compounds, or VOCs, from sealed chamber environments.
While monstera deliciosa wasn’t directly tested in that initial study, other members of the Araceae family were, and they performed well.
Scientists discovered that plants remove these toxins through a natural process called phytoremediation.
This simply means the plants take up harmful chemicals through their pores and transport them down to the roots.
Once there, beneficial microbes in the soil break the toxins down into compounds that are harmless to humans.
So when you ask if monstera plants clean the air, the answer has a solid scientific foundation.
2. What Specific Pollutants Can Monstera Remove?
Monstera plants can help clean the air of several common indoor pollutants that come from everyday household items.
The most notable VOCs that monstera plants remove include formaldehyde, benzene, xylene, and toluene.
Formaldehyde is often released by new furniture, pressed wood, carpets, and certain cleaning products.
Benzene is found in paints, glues, and synthetic fibers, while xylene and toluene can off-gas from printing inks and rubber.
When your monstera plant absorbs these fumes, it essentially detoxifies your indoor air.
It’s important to remember that this cleanup happens at a fairly slow pace, and in small amounts.
Still, having a monstera plant contributes to a healthier indoor environment by removing at least some of the chemicals you’d rather not breathe.
3. It’s Not Just the Leaves: Soil Matters
The actual air-cleaning power of a monstera plant goes beyond the big, beautiful leaves you see.
One of the biggest misconceptions is that monstera plants clean the air by simply capturing dust on their foliage.
In reality, the roots and soil do a significant portion of the work.
Gaseous pollutants are absorbed by the leaves and then migrate down into the potting mix.
Once they reach the soil, microorganisms like bacteria and fungi use those chemicals as a food source.
This is why maintaining a healthy root system is so important if you want your monstera plant to clean the air effectively.
If your monstera is sitting in poor, compacted soil or sitting in stagnant water, the microbial community won’t thrive.
Keep your monstera in a well-aerated potting mix and avoid overwatering, and it will reward you with better air purification.
How Effective Are Monstera Plants at Cleaning the Air?
So now you know the mechanism, but the question of effectiveness is where the “do monstera plants clean the air” debate really heats up.
There’s a big difference between a laboratory chamber and your actual living room.
In a tightly sealed lab, plants show impressive removal rates; in your home, conditions are completely different.
Let’s look at some practical factors that determine how well monstera plants clean the air for you.
1. The “One Plant Per 100 Square Feet” Rule
There’s a popular guideline that suggests using about one houseplant for every 100 square feet of living space.
Following that rule, a 300-square-foot living room would need at least three monstera plants to make any measurable difference.
That’s because a single monstera plant only filters a small volume of air per hour.
To put it in perspective, you would need around 10 monstera plants in a typical 150-square-foot room to get the same effect as an actual air purifier.
That number might sound crazy, but it puts the reality of plant-based air cleaning into context.
Having monstera plants clean the air in your home is a long-term, low-level improvement, not a quick fix.
2. Monstera vs. Other Air Purifying Plants
If you want to maximize air purification, monstera plants aren’t the best choice on the market.
English ivy, peace lilies, spider plants, and pothos all outperform monstera when it comes to VOC removal per plant.
But that doesn’t mean monstera plants clean the air badly.
It just means they’re a less efficient tool for that specific job.
Most people choose monstera because of those dramatic split leaves and the incredible jungle-like vibe they give a room.
If you combine a monstera with some of the more efficient purifiers, you can get both style and substance.
Honestly, monstera plants clean the air well enough to still be worth including in your green family.
So, Do Monstera Plants Clean The Air?
So, do monstera plants clean the air?
Yes, they absolutely do.
Monstera plants clean the air by absorbing VOCs, filtering out small amounts of formaldehyde and benzene, and improving overall indoor air freshness.
But they’re not miracle purifiers, and you’ll need multiple plants, good airflow, and patience to see meaningful results.
A single monstera plant will still make your space feel more alive and can passively improve air quality over time.
So go ahead and give that monstera a spot in your living room, office, or bedroom.
Just remember that monstera plants clean the air best when they’re healthy, well-watered, and surrounded by a few leafy friends.
The more monstera plants you have, the more they can clean the air for you.
In the end, do monstera plants clean the air?
They really do.
