Indoor plants don't just brighten up the place, many also act as an air-purifying system for your home. 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. Let's go!

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?!
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 and varnish), formaldehyde (often seen in glues, paints and detergents) and trichloroethylene (commonly used in cleaning products).
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.
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. 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.

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.
