Your Indoor Air Is Dirtier Than You Think
Air purifying hanging plants are one of the easiest ways to fight back against indoor pollution — and the best options include:
- Pothos (Epipremnum aureum) — 77% VOC removal, nearly indestructible
- Spider Plant (Chlorophytum comosum) — pet-safe, 62.5% VOC removal
- Syngonium — 81.69% VOC removal, great for small spaces
- English Ivy — trails beautifully, removes benzene and formaldehyde
- Boston Fern — high humidity lover, excellent for bathrooms
- Philodendron scandens — low maintenance, pet-friendly trailing vines
- Spanish Moss (Tillandsia usneoides) — soilless, zero-fuss, unique look
Indoor air can carry 2 to 5 times more pollutants than outdoor air. Benzene from furniture, formaldehyde from cleaning products, trichloroethylene from paints — these invisible toxins build up in your home every day.
The good news? A handful of well-placed hanging plants can make a real dent.
NASA’s landmark 1989 clean air study was one of the first to show that common houseplants can remove VOCs (volatile organic compounds) from indoor air. More recent lab research backs this up — one study found that Syngonium podophyllum removed over 81% of VOCs in controlled conditions, while Pothos hit 77%.
Hanging plants are especially smart for busy urban homes. They free up floor space, stay out of reach of pets and kids, and add a dramatic visual layer to any room — all while quietly cleaning the air above your head.
This list covers the best air-purifying hanging plants, what they actually remove, how hard they are to keep alive, and where to put them for maximum effect.

The Science of Air Purifying Hanging Plants
We often think of plants as mere decorations, but they are actually sophisticated biological filters. The primary advocate for this was Dr. Bill Wolverton, who led the 1989 NASA Clean Air Study. His research proved that certain plants could scrub the air of harmful chemicals. But how exactly do they do it?
The process is called phytoremediation. Plants absorb gases through tiny pores on their leaves called stomata. Once inside, the toxins are moved down to the roots, where soil microbes break them down into food for the plant. In the case of air purifying hanging plants, this means the very pollutants making you feel sluggish are being converted into plant fuel.
Recent scientific research has taken these findings even further. According to a Comparative evaluation of air phytoremediation potential of four ornamental potted plants for ecofriendly biofilter applications | Scientific Reports , different species have varying “removal efficiencies” for Volatile Organic Compounds (VOCs).
For example:
- Cordyline fruticosa: Showed a staggering 87.5% VOC removal efficiency.
- Syngonium podophyllum: Achieved 81.69% efficiency and actually reduced particulate matter (PM2.5 and PM10) by 100% in lab tests.
- Epipremnum aureum (Pothos): Clocked in at 77.23%.
- Chlorophytum comosum (Spider Plant): Reached 62.5%.
These plants target specific “bad guys” in your air:
- Benzene: Found in plastics, synthetic fibers, and tobacco smoke.
- Formaldehyde: Common in pressed-wood furniture, carpets, and household cleaners.
- Trichloroethylene: Found in printing inks, paints, and lacquers.
- Toluene and Xylene: Often found in nail polish and adhesives.
For those of us living in high-traffic urban areas, these plants act as a secondary defense against smog and dust. You can find more details on hardy air-purifying plants that can withstand the tougher conditions of a busy home.
Top 7 Air Purifying Hanging Plants for Your Home
When we select plants for hanging baskets, we look for “trailers” or “cascaders”—plants that naturally grow downward to create a lush, vertical jungle effect. Here are our top picks based on recent scientific data and ease of care.
1. Syngonium podophyllum (Arrowhead Vine)
This is a hidden gem in air purifying hanging plants. While many people know Pothos, Syngonium is a powerhouse that achieved an 81.69% VOC removal efficiency in recent studies. It’s also incredible at capturing dust and particulate matter. As it matures, it develops long, trailing vines that look stunning in a hanging pot.
2. Cordyline fruticosa (Ti Plant)
Though often grown as an upright plant, smaller varieties or young Ti plants can be used in mixed hanging arrangements. It holds the crown for the highest VOC removal efficiency at 87.5%. Its vibrant colors (pinks, reds, and purples) add a pop of life that green-only plants can’t match.
3. English Ivy (Hedera helix)
NASA loves English Ivy for its ability to tackle formaldehyde. It’s a classic choice for a reason—it’s incredibly hardy and drapes beautifully. You can find high-quality English Ivy Plant in Hanging Basket – Lush, Air-Purifying Indoor/Outdoor Greenery – The Garland Guy that are ready to go right out of the box.
4. Boston Fern (Nephrolepis exalta)
If you have a humid spot, the Boston Fern is your best friend. It’s a top-tier air purifier that excels at removing xylene and formaldehyde. Its feathery fronds act like a natural humidifier, releasing moisture into the air, which is great for your skin and respiratory system during dry winters.
5. Philodendron scandens (Heartleaf Philodendron)
The Philodendron scandens – Air Purifying Evergreen Indoor Plant in Hanging Basket, Bright Green Trailing Vines is one of the most forgiving plants you can own. It thrives in low light and is highly efficient at scrubbing the air. Its heart-shaped leaves make it a decorative favorite for bedrooms.
6. Pothos (Epipremnum aureum)
Often called “Devil’s Ivy” because it’s nearly impossible to kill, Pothos is the gold standard for beginners. With a 77.23% removal efficiency, it’s a workhorse for your indoor air quality. It’s also very easy to propagate, meaning you can turn one plant into a whole house full of air scrubbers.
7. Spider Plant (Chlorophytum comosum)
We call this the “eight-legged hero.” It’s famous for its “spiderettes”—baby plants that hang down from the mother plant. It’s a solid performer (62.5% efficiency) and is incredibly resilient. For more on this specific hero, check out why spider plants are the eight-legged-heroes of your living room.
Best Air Purifying Hanging Plants for Pet Owners
One of the biggest concerns we hear is: “Will my cat get sick if they nibble on this?” It’s a valid worry, as many popular plants (like Pothos and Philodendrons) contain calcium oxalate crystals which can be irritating or toxic to pets.
If you have furry friends, focus on these non-toxic air purifying hanging plants:
- Spider Plant: Completely non-toxic and even slightly hallucinogenic to cats (they might bat at the leaves!), it’s a safe bet. Read more about spider plants vs indoor air pollution to see how they protect your pets’ air too.
- Boston Fern: Unlike “True” ferns, the Boston Fern is safe for cats and dogs.
- Spanish Moss: This soilless wonder is a bromeliad, not a moss, and is pet-friendly. You can see how it looks at Tillandsia usneoides – Spanish Moss Hanging Epiphyte .
- Lemon Button Fern: A smaller, easier-to-manage relative of the Boston Fern that is also safe.
Pro Safety Tip: Even with non-toxic plants, hanging them high is the best strategy. It prevents “pica” (the urge to eat non-food items) and keeps your beautiful vines from becoming a chew toy.
How to Maintain Your Air Purifying Hanging Plants
Hanging plants have slightly different needs than their floor-dwelling cousins. Because they are higher up, they are often in warmer, drier air (since heat rises).
- Watering: Checking the soil can be tricky when a plant is six feet in the air. We recommend using a long-necked watering can or taking the basket down once a week for a soak. If you’re a forgetful waterer, look into low-water air-purifying plants.
- Humidity: Plants like ferns and English Ivy love a good misting. This helps keep their leaves clean so they can continue absorbing toxins efficiently. If the leaves get dusty, they can’t “breathe” or purify as well.
- Light: Most trailing plants love “bright, indirect light.” This means a spot near a window where they can see the sky but aren’t being baked by direct sunbeams.
- Mess-Free Hanging: Watering hanging plants can lead to drips on your carpet. We’ve got you covered with a guide on how to hang hanging baskets inside without making a mess.
- Maintenance: Don’t be afraid to prune! Pruning encourages fuller growth and removes dead material that could attract pests. If you’re dealing with a rare variety like Philodendron Warszewiczii: How to Care for This Air Purifying Plant – Plant America , follow specific pruning guides to keep its multi-lobed leaves healthy.
Maximizing Benefits: Placement and Room Size
How many plants do you actually need? While one plant is better than zero, you need a certain “density” to see a measurable difference in air quality. A general rule of thumb is one medium-sized plant for every 100 square feet of living space.
Air Purification Placement Guide
| Room Type | Primary Pollutant | Best Hanging Plant | Why? |
|---|---|---|---|
| Bedroom | CO2, Formaldehyde | Pothos / Spider Plant | Pothos is hardy; Spider plants are safe for pets sleeping nearby. |
| Bathroom | Ammonia, Xylene | Boston Fern | Loves the high humidity from showers; filters cleaning chemicals. |
| Kitchen | Cooking fumes, Benzene | English Ivy | Excellent at scrubbing toxins from gas stoves and cleaning agents. |
| Living Room | VOCs from furniture | Syngonium / Cordyline | High efficiency for larger spaces with more “new furniture” smell. |

Airflow Tip: Plants work best when air is moving. Placing a hanging plant near a slightly cracked window or in the path of a ceiling fan helps the plant “capture” more pollutants as they drift by.
Hanging vs. Upright Plants: Pros and Cons
Why choose air purifying hanging plants over a standard potted Snake Plant or Peace Lily? It mostly comes down to your lifestyle and space.
The Pros of Hanging Plants:
- Floor Space: In small apartments, floor space is gold. Hanging plants use the “dead space” near your ceiling.
- Visual Interest: They draw the eye upward, making rooms feel taller and more “jungle-like.”
- Safety: Keep toxic plants away from toddlers and pets by using stop floor-hogging with these ceiling hanging plant baskets.
- Light Access: You can hang plants directly in front of windows where they get the best light without blocking your walkway.
The Cons of Hanging Plants:
- Accessibility: Watering and pruning can require a step stool.
- Drying Out: Air near the ceiling is often warmer, meaning hanging baskets dry out faster than floor pots.
- Weight: You need to ensure your ceiling hooks for plants are properly installed into a joist or use heavy-duty anchors.
If you want to combine style with function, try using geometric hanging pots to give your greenery a modern, architectural edge.
Frequently Asked Questions about Indoor Greenery
How many hanging plants do I need per room?
For noticeable air quality improvement, aim for 2-3 medium-sized hanging plants in a standard 12×12 room. If you are dealing with a freshly painted room or new carpet, you might want to double that number temporarily to handle the “off-gassing.”
Which hanging plant removes the most formaldehyde?
According to NASA and subsequent studies, English Ivy and Boston Ferns are the champions of formaldehyde removal. Pothos is also a very strong contender and much easier to care for if you don’t have high humidity.
Are all trailing plants safe for cats and dogs?
No. Many popular trailing plants like Pothos, Heartleaf Philodendron, and English Ivy are toxic if ingested. If you have a plant-chewing pet, stick to Spider Plants, Boston Ferns, or Spanish Moss.
Can air plants (Tillandsia) purify the air?
Yes, though their surface area is smaller than a large-leafed Pothos. Species like Tillandsia mooreana | Moore’s air plant Houseplants/RHS absorb moisture and nutrients (including some airborne particles) through their leaves. They are great for “supplemental” purification and look amazing in hanging glass globes.
