Can Spider Plants Purify The Air In Your Home

Spider plants can purify the air in your home, but the truth about how effective they are might surprise you.
 
If you’ve been asking can spider plants purify the air in your home, the short answer is yes, spider plants do have air-purifying abilities.
 
But here’s the thing, the way spider plants purify air in real-world homes is a little different from what you may have read about on the internet.
 
Many people bring spider plants indoors specifically because they want these plants to clean the air in their living spaces.
 
And while your spider plant absolutely does help, it’s not a magic bullet for turning bad indoor air quality into fresh mountain air overnight.
 
In this post, we’ll explore the science behind how spider plants can purify the air, what they actually remove, and what you can realistically expect from your spider plant when it comes to air purification.
 
Let’s get into it.
 

Why Spider Plants Can Purify The Air In Your Home

The main reason people believe spider plants can purify the air in your home comes down to one famous NASA study from the 1980s.
 
Let’s break down exactly what that study found and what spider plants are best at removing.
 

1. The NASA Clean Air Study Put Spider Plants to the Test

Back in 1989, NASA published a study looking at which houseplants could help purify air inside sealed environments like space stations.
 
Spider plants performed exceptionally well in that study.
 
The study showed that spider plants can remove certain volatile organic compounds from the air.
 
This is where the reputation that spider plants can purify the air in your home originally came from.
 
But keep in mind the study was done in a sealed laboratory chamber, not in your average living room with open windows and doors.
 

2. Spider Plants Are Excellent at Removing Formaldehyde

One of the big reasons spider plants can purify the air is their ability to absorb formaldehyde.
 
Formaldehyde is a common indoor pollutant found in carpets, furniture, cleaning products, and even some fabrics.
 
Spider plants take in this compound through their leaves and break it down inside their tissues.
 
So if you want to know which specific pollutant your spider plant can handle best, formaldehyde is the answer.
 

3. Spider Plants Also Filter Out Xylene and Toluene

Beyond just formaldehyde, your spider plant can also remove xylene and toluene from indoor air.
 
These are chemicals often released by paints, adhesives, and gasoline fumes that may sneak into your home from attached garages.
 
So yes, spider plants can purify the air of multiple VOCs, not just one.
 
This makes them a solid all-rounder in the houseplant world.
 

4. Oxygen Production Happens as a Bonus

Like all green plants, spider plants take in carbon dioxide and release oxygen during photosynthesis.
 
Now this doesn’t mean they’ll dramatically boost the oxygen levels in a large room.
 
But the fact that spider plants can purify the air while adding a little fresh oxygen is definitely a nice perk.
 
It’s not the main reason to buy one, but it contributes to that feeling of fresher air.
 

What Spider Plants Realistically Do For Your Indoor Air Quality

Now that we know spider plants can purify the air in a lab setting, let’s talk about real-world expectations.
 

1. You Need Many Spider Plants To Make a Meaningful Difference

Here’s the honest truth, for your spider plant to truly purify the air in a typical room, you would need dozens of them.
 
One single NASA study recommended having at least two plants per 100 square feet of space.
 
And even that number is debated because modern homes are less airtight than the laboratory chambers used in the study.
 
So while spider plants can purify the air, they are not a replacement for a mechanical air purifier if you have serious indoor air quality concerns.
 

2. Spider Plants Still Improve Your Home Environment in Other Ways

Even if your spider plant isn’t scrubbing every pollutant out of the air, it still benefits your home in meaningful ways.
 
Spider plants increase humidity by releasing moisture vapor through their leaves during transpiration.
 
This can help with dry indoor air, especially during winter months when heating systems dry everything out.
 
Plus, having greenery around has been shown to reduce stress and boost mood.
 
So while you might not rely solely on spider plants to purify the air, they absolutely make your home feel healthier.
 

How To Get The Most Air Purification Out Of Your Spider Plant

If you want your spider plant to do as much air cleaning as possible, here are a few practical tips.
 

1. Keep the Leaves Clean and Dust-Free

Dust buildup on the leaves blocks the plant’s ability to absorb pollutants.
 
Wipe down the leaves of your spider plant every few weeks with a damp cloth.
 
A clean spider plant can purify the air much more efficiently than a dusty one.
 

2. Give Your Spider Plant Enough Light

Spider plants need bright indirect light to stay healthy and produce new growth.
 
A plant that is stressed or struggling in low light won’t have the energy to purify much at all.
 
So put your spider plant near a window but out of direct afternoon sun.
 

3. Grow More Baby Spider Plants

Spider plants produce offsets called spiderettes that you can propagate into new plants.
 
The more spider plants you have in your home, the more potential air purification you get.
 
Even if one spider plant can’t purify an entire room on its own, a cluster of spider plants placed strategically can make a noticeable difference.
 

So, Can Spider Plants Purify The Air In Your Home?

Spider plants can purify the air in your home, especially when it comes to removing formaldehyde, xylene, and toluene.
 
But you should understand that a single spider plant won’t transform the air quality of a large room overnight.
 
If you ask whether spider plants can purify the air enough to replace a filter system, the answer is no, not realistically.
 
However, when combined with good ventilation, regular cleaning, and a few other houseplants, your spider plant contributes to a fresher, healthier indoor environment.
 
So go ahead, enjoy your spider plant and let it work its quiet magic, knowing that even a small amount of help is still helpful.
