As plants photosynthesise, they absorb carbon dioxide and release fresh oxygen into the air, but air-purifying plants go one step further. They can actually absorb harmful chemicals often found in the home, making the air that we breathe inside much cleaner. Whether you're looking for full-foliage plants for your bedroom or succulents that thrive in low-lit bathrooms, there are heaps of options to choose from.
In this guide, we'll discuss the main points to consider whilst shopping, including checking whether the plant is safe for cats, dogs and babies. We'll also share our top ten air-purifying plants to buy in the UK. Moreover, we have partnered with interior designer Belen Dakak for reviewing and fact-checking the article to deliver you the best information.

First on the list, check which toxins each specific plant species absorbs. Many will be able to fight off common household toxins such as xylene (often found in paint or cigarette smoke), benzene (found in furniture wax, paints, varnish and carpeting), formaldehyde (often seen in glues, paints detergents, floor lacquers and certain moulded plastics), trichloroethylene (commonly used in cleaning products) and toulene (paints).
If you have any wood-burning stoves, tumble dryers or gas stoves, it might also be worth looking at plants that remove toxins in carbon monoxide. Other plants protect the air from toxins found in ammonia – which can enter the atmosphere if you have cat litter boxes or use glass or window cleaning products.
Alongside your new green leafy purifier, why not consider an actual air purifier for even cleaner air?
One of the first things to think about when it comes to conditions a plant needs is light. If you have a sunshine-flooded, south-facing flat that receives streams of direct sunlight, you shouldn't have too much of a problem.
For people living in small apartments that only get sun in a couple of rooms, you need to choose your plants a little more carefully. If in doubt, always choose plants that can thrive in low-lit environments. A good rule of thumb is to go for plants that originate from subtropical climates. These have learnt to cope in conditions sheltered from the sun by taller trees and canopies, so will do well indoors without much direct sun.
Some air-purifying plants, such as the Elephant Ear, require extremely precise conditions to flourish. They need a decent amount of light, the perfect amount of humidity and need to be misted regularly – but only a little – the leaves cannot be wet! You also need to ensure that they have protection from pests and wipe their leaves regularly.
If you can't provide this type of heavy maintenance, stick to an easier plant such as Pothos. Nicknamed Devil's Ivy, this plant has earned its name through its hardy ability to withstand almost any conditions. Overwatering, underwatering, near pitch-black lighting conditions – and it still manages to thrive! Pothos is a perfect choice for people who don't have much spare time.
The Royal Horticultural Society (RHS) also recommends the following easy care houseplants, though no plants will tolerate a site of complete darkness like a windowless room, as they need daylight to produce food for themselves: Sanseviera (will tolerate some drought, hapin the sunsun or part shade, grow in low humidity and need well-drained compost).
Spathiphyllum (tolerates bright light through to full shade, happy in average room temperatures, and tolerant of lower relative humidity) and Philodendron (Tolerant of lower relative humidity grows well in shade or brighter light, happy on average room temperatures and tolerant if under-watered occasionally).
Plants look wonderful in bathrooms and kitchens. They brighten up the room by adding a bit of colour to a generally white-based theme. That said, if you plan on placing your plant here, you need to make sure it can withstand humid environments.
Species such as Calathea, Air Plants and Monsteras are perfect for steamy bathrooms, as do Boston Fern, as they love humid conditions and are one of the best for absorbing moisture. Snake Plants are also a good choice as they are exceptionally hardy and can thrive in any level of humidity. Due to the regular steam in the bathroom, you shouldn't need to mist them either!

One essential point to remember is that not all plants are safe for animals. Cats, in particular, seem to enjoy pawing at the soil or trying to climb plants with large leaves. So if you have any pets, make sure the plant you are buying is non-toxic and safe for them to investigate.
That, unfortunately, rules out many of the uber-exotic looking greens like Alocasia or Fig Leaf, but there is still a huge range of leafy greens to choose from that are 100% safe. Some species that are pet-friendly are Spider Plants, Areca Palms, Bamboo Palms and Boston Ferns.

Known as both Devil's Ivy and Golden Pothos this sizeable waxy-leafed plant is a great one for beginners. It thrives under even the most unsuitable conditions, such as extremely low light and over-watered or underwatered soil. They do like moisture, so they do especially well in a bathroom.
Pothos reduces most common household toxins such as xylene, benzene, formaldehyde and trichloroethylene. This is also a great choice if you want a bright climbing plant that will weave its way across beams or along high shelves. Apparently, it's harder to actually kill this plant than it is to keep it alive. Bonus: this one comes in a hanging pot!
Aloe Vera is one of those wonder-plants that we think should have a place in every home. As well as protecting the air quality by reducing toxins, Aloe Vera is also medicinal. Cut open the leaves, and you'll find a cooling gel with anti-inflammatory properties that can be applied topically to cool sunburn and heal wounds.
These plants work to purify the air of formaldehyde and benzene, which is commonly found in detergents and varnishes. They prefer a warm, well-lit spot too, making them an overall top choice for brightening up your kitchen windowsill.
Dracaenas are another one that can grow to incredible heights. Repotted and provided with its optimum growing conditions, a Dracaena can reach up to 15 feet tall! This makes them a must-have if you're decorating a big, open space.
Preferring indirect sunlight, this plant is suitable for most homes, and it has a nice red finish to its leaves which adds an unusual flash of colour. It works well at filtering the three main household toxins, xylene, trichloroethylene and formaldehyde, and it doesn't require much water at all – just a little misting.
English Ivy has long been touted as one of the best houseplants for air purifying. It's often found crawling outside walls, but they also grow exceptionally well indoors. They prefer a more cramped existence, so you don't need to re-pot them at all and they can be left growing in a small container for years.
As well as combatting toxins, English Ivy has been shown to help reduce mould levels and airborne faecal particles in the air, making them a great addition to the bathroom. English Ivy is a thirsty plant, though, and requires a good amount of watering and sunlight.
There's a reason why Mother-in-Laws Tongues (also known as Snake Plants) can be seen in almost every Instagrammer's posts – they're one of the hardiest houseplants around. They can thrive in virtually any lighting conditions and they even release oxygen at night, making this a great plant to place in the bedroom for a good night's sleep.
This is an excellent choice for forgetful plant parents, as they do well in dry conditions – just make sure not to overwater them. They are brilliant at reducing toxins like formaldehyde, trichloroethylene, benzene, and xylene.
If you're looking for something a bit more substantial, bushy and dramatic, try an Areca Palm. These are excellent for big, open, white spaces and they're also fairly easy to look after, requiring just a couple of watering sessions each week during summer and a bit less during winter.
One of the Areca Plants' best qualities is that they are completely safe for cats, dogs, and babies, so you don't need to worry about protecting them against prying fingers or paws. They are also one of the best plants for removing toxins in the air.
Peace Lilies are also an excellent choice if you haven't yet grown your green thumbs! They are really easy to look after, just needing the occasional water and a bit of fertiliser to bring in those lovely white flowers.
Peace Lilies are very popular for their beautiful appearance, as well as the fact they help to remove the usual household toxins, including carbon monoxide, which can contaminate the air when using wood burners, gas stoves and dryers. They are, however, harmful to animals, so make sure to keep them well out of reach.
Chinese Evergreens are one of the easiest house plants to keep alive, making them great for newbie plant parents! They can live in most conditions, whether dry, moist, sunny or shaded, but they really thrive in humid conditions. They do, however, require decent well-draining soil.
This makes them an ideal option for placing in hanging baskets in the kitchen or bathroom. When it comes to toxins, Chinese Evergreens do well to eliminate formaldehyde, xylene and benzene in the air, which is commonly found in cosmetics and detergents.
Originating from India, Rubber Plants thrive in bright light, so they're best kept in areas that receive a decent amount of sunlight. Apart from the regular watering, they don't require much maintenance, so they are easy to keep alive.
This plant has a striking look and keeps its healthy appearance with minimal effort; it's also meant to be one of the best for cleansing the air of toxins. It is, however, poisonous to animals, so we wouldn't suggest this one if you have pets at home.
The Weeping Fig plant is beautiful, but it does require a bit of extra maintenance, including the need for the soil to be thoroughly dried out in between its weekly waterings. It can reach highs of 10 feet tall, so make sure you have enough room for it to grow. They also don't like change, so try not to move it about too much.
This plant thrives best when in direct sunlight, so you will need to ensure that you can provide these consistent conditions if you want the plant to reach its full potential. Like many other air-purifying plants, this one reduces formaldehyde, trichloroethylene and benzene toxins in the air.
We all know that plants are good for us. As our science lessons taught us, they keep our air clean by recycling carbon dioxide into oxygen. That's why we often have a higher sense of wellbeing, clarity and focus when we're around plants – our oxygen levels have been topped up. But air-purifying plants do one better.
NASA did a study in 1989, which proved that certain plants are able to reduce toxins in the air like formaldehyde and benzene. This is especially important in this day and age when we dress our houses in chemical-laden paints and treated vinyl floors, as well as cleaning with highly toxic products.
By placing even just a few air-purifying plants in each room, you can detoxify the space and improve the air quality. This benefits our mental health, concentration levels, productivity, quality of sleep and can even help you recover from illnesses quicker. Why wouldn't you take in a couple of our green-leafed friends?!
While it is difficult to quantify the exact number of plants required to purify indoor air, we recommend at least two healthy plants for every 100 square feet (9.3 square metres) of space. The larger and leafier the plant, the better it is at purifying more air.
Yes. Through photosynthesis, plants take in carbon dioxide and release oxygen. But the amount of oxygen it can release depends heavily on environmental factors, mainly the amount of light it receives. When plants do not enough light to photosynthesise, they start absorbing oxygen and releasing carbon dioxide instead.
