Plants that dehumidify your home: which ones should you choose?

If your home feels like a tropical greenhouse, minus the exotic palm trees and the pineapple cocktails, it might be time to look into the plants that can help dehumidify your interior. Yes, you read that correctly: some plants are able to absorb part of the moisture in the air. They won't replace an electric dehumidifier in extreme cases, but they can contribute to a drier, healthier environment… and a far prettier one.

How can plants dehumidify a home?

To understand the role plants play in reducing humidity, it helps to remember that these living things breathe, perspire and drink… rather like us. The difference is that they do it with far more elegance.

Absorption through leaves and roots

Some plants absorb moisture from the air through their leaves. It is part of their vital process: capturing the water present in the air to meet their hydration needs. The roots, meanwhile, absorb the water held in the soil. In other words, the more water a plant takes from the air, the less it depends on watering: good news if you tend to be forgetful!

Transpiration (or evapotranspiration): friend or foe?

All plants transpire: it is how they regulate their temperature. The catch is that this transpiration releases moisture back into the air. So how, you may ask, can a plant reduce humidity if it gives some off itself? Excellent question! The answer lies in the balance: certain species absorb more moisture than they release, particularly in a very damp environment. They then become genuine **natural water pumps**.

The overall regulating effect

Beyond absorption alone, plants help create a **healthier microclimate** by regulating air circulation, filtering certain pollutants and bringing a sense of well-being. A room filled with well-chosen plants "breathes" better, and so do you.

The best plants for dehumidifying your home

Here is a selection of plants known for their ability to reduce humidity. Some are famous, others less well known, but all have a natural talent for drinking the water out of the air without asking permission.

Nephrolepis exaltata (Boston fern)

The Boston fern is a real star among air-purifying plants… and a little moisture vacuum. It loves damp environments, which makes it the perfect companion for your bathroom. Bonus point: its dense foliage instantly gives any room a chic jungle feel.

Spathiphyllum (peace lily)

If one plant deserved a gold medal for absorbing moisture, it would probably be the **peace lily**. Not only is it beautiful, with its elegant white flowers, it also soaks up excess water from the air and filters out many unwanted chemical compounds.

Chlorophytum comosum (spider plant)

Easy to care for and able to survive even the most absent-minded owners, the spider plant is ideal in a home where damp is an issue. It absorbs moisture from the air effectively and grows quickly: a true indoor champion.

Tillandsia (air plant)

Tillandsias are remarkable plants: they live… without soil! They absorb moisture directly through their leaves thanks to trichomes (tiny absorbent structures). Lightweight and easy to hang, they are perfect in a shower room or a kitchen.

The orchid

Contrary to what you might think, the orchid can be an ally against damp, especially in a warm room. It draws moisture from the air to feed its aerial roots, while adding a touch of unrivalled elegance.

English ivy

A genuine champion of air filtration, English ivy also absorbs some of the moisture in the air. One word of caution: it prefers cool, well-lit rooms, and it can be toxic to pets.

The table below sums up where to place each of these six plants and what to expect from them.

Plant	Where to place it	What it brings	Watch out for
Boston fern	Bathroom	Loves damp rooms, dense foliage	Needs a genuinely humid room
Peace lily	Bathroom, bedroom	Absorbs excess moisture and filters chemical compounds	Low CO₂ output at night, hence suited to bedrooms
Spider plant	Any damp home	Soaks up ambient moisture well and grows fast	Forgives missed watering better than the others
Tillandsia	Shower room, kitchen, hanging	Lives without soil, absorbs through its leaves via trichomes	Light enough to solve any space problem
Orchid	Warm room	Draws moisture from the air through its aerial roots	Works best in the heat
English ivy	Cool, well-lit room	Top air filter, takes up part of the moisture	Can be toxic to pets

What using dehumidifying plants really involves

Bringing in plants to reduce humidity is a charming, eco-friendly and attractive solution… but it isn't magic. Here is what you need to know.

They are no substitute for a real dehumidifier

Let's be clear: if your humidity level goes above 70%, or if your windows steam up systematically in winter, plants will not be enough. They are excellent as a supplement, but not as your main solution.

They need a minimum of care

Most dehumidifying plants like humidity… but not to excess. Ironic, isn't it? Water them sparingly, clean their leaves and make sure they get enough light.

They shape the decor and layout of your space

Some plants are bulky, others need hanging, and others again like bright corners. That may call for a few adjustments to the way your furniture is arranged. But let's be honest: a house full of plants does look very Pinterest.

They really do improve air quality

Even though their dehumidifying effect remains limited, they bring many other benefits: cleaner air, better mood, less stress and even a boost in productivity. A plant is a bit like a quiet, kind-hearted housemate.

Where should you put plants for maximum effect?

Positioning is crucial if you want to make the most of a plant's natural ability to absorb moisture.

In the bathroom

Between hot showers and ventilation that is sometimes inadequate, this is the dampest room in the house. The Boston fern, the peace lily and the tillandsia will all feel perfectly at home there.

In the kitchen

Boiling pasta, evaporation, steamed-up windows: the kitchen sends humidity soaring like a bread oven. Place plants on the shelves or near the window.

In the bedroom

Thanks to their ability to absorb moisture and purify the air, plants can improve the quality of your sleep. Choose species that release little CO₂ at night (the peace lily, for example).

Conclusion: can plants really dehumidify a house?

Yes… but only up to a point. Plants that absorb moisture are valuable allies in the fight against an interior that is a little too damp. Without replacing technical solutions, they help create a more balanced, healthier and decidedly more attractive environment.

So why not invite a few ferns, orchids or spider plants to join your home? They will help you breathe drier air… and they will never complain about the weather.

Frequently asked questions

Can plants replace a dehumidifier? No. If humidity goes above 70% or your windows fog up every winter, no plant will solve that. They work as a supplement, never as the main solution.

Which plants work in a bathroom that is too damp? The Boston fern, the peace lily and the tillandsia all thrive there. Bathrooms are warm and often poorly ventilated, which suits them. The tillandsia can be hung up, which solves the space problem.

Doesn’t a plant that transpires raise the humidity? Partly, yes. Every plant transpires to regulate its temperature and therefore releases water into the air. It comes down to balance: some species absorb more moisture than they give back, especially in a room that is already very damp.

Where should I put them for them to actually help? In the rooms where the moisture is produced: the bathroom, with its hot showers and often poor ventilation, and the kitchen, where cooking sends steam up. In the bedroom, go for species that release little CO₂ at night, such as the peace lily. Put them on shelves or near a window rather than in a dark corner.

Is English ivy dangerous for a cat or a dog? It can be toxic to pets, so avoid it if a cat or dog roams freely in the property. It also needs cool, well-lit rooms, which limits where you can put it. If those two constraints bother you, the spider plant does the job without the same caveats.

Do these plants need a lot of care? A little, but nothing unmanageable. They like humidity without liking excess: water them in moderation, wipe the leaves now and then, give them enough light. The spider plant forgives the most neglect, which makes it a good starting point.
