The humble house plant has been revealed as a key weapon in the war on indoor pollution – now new research has revealed exactly which plants are the best for sucking up toxins.

Researchers from GardeningExpress.co.uk decided to study the purifying capabilities of a range of common houseplants following an NHS report on pollution in the home.

The NHS report highlighted how toxins from furnishings, detergents and paints can all have adverse effects on our health.

The report went on to claim that indoor pollutants could be causing thousands of premature deaths per year in the UK.

But the good news is that households can help to improve the air quality inside their homes by introducing a houseplant in each room. According to NASA, up to 87% of airborne toxins can be removed by plants.

Now the researchers at GardeningExpress.co.uk have identified exactly which plants are most efficient at improving air quality.

Having plants in a home could also have health benefits with suggestions they reduce headaches, improve breathing related illnesses and decrease high blood pressure.

Chris Bonnet, founder of GardeningExpress.co.uk said: “The quality of air inside some homes can be just as bad as the levels of pollution outside. The air homeowners breathe in could turn out to be just as bad as walking down a busy street in a city.

“Harmful toxins such as formaldehyde and benzene found in some household items pollute the air which can have an effect on people’s health.

“But thanks to Mother Nature there are specific plants Brits can use to dramatically improve the air quality inside their homes.

“Acting as a natural air purifier these plants remove many of the harmful toxins and release fresh oxygen, creating a healthier environment to live in.”

Here are 6 of the most effective plants to improve air quality in your home:

Aloe vera

Aloe Vera

Fragrant aloe vera is not only useful when soothing a kitchen burn, but also very effective at purifying polluted air in a home. Unlike most plants, aloe vera emits oxygen during night time as well as day time, meaning it improves the quality of air 24 hours a day.

Peace lily

Peace Lily

This evergreen plant was found to be one of the most effective at removing airborne toxins, particularly the carcinogenic benzene, which is a potential cancer-causing pollutant. Peace lilies are easy to care for as they require little light or water to remain healthy, however any households with pets should be wary as the plant is poisonous if consumed.

Snake plant

Snake Plant

Also known as Mother-In-Law’s Tongue, this evergreen perennial is another of the best plants for improving air quality as it was found to be most effective at removing formaldehyde, which is respiratory irritant commonly used in cleaning products.

The snake plant is similar to aloe vera in being one of the few to release at oxygen at night, but be careful not to overwater it as the roots will rot if they stay moist for too long.

English ivy

English Ivy

A popular house plant that is not only good at improving air quality but one that can also help to reduce mould. Placing the plant in a bathroom is where it will be most effective due to the amount of moisture in the air. English ivy does need some care as it is recommended to give it four hours of sunlight per day along with a generous watering.

Boston fern

Boston Fern

With its mass foliage, the Boston fern is thought to rid the air of harmful toxins as well as improving the humidity of a room due to it restoring moisture in the air. The plant could also have potential health benefits for people who suffer from dry skin.

Weeping fig

Weeping Fig

Originally from Asia and Australia this plant has been popular in the UK since Victorian times. Weeping figs are particularly effective at naturally filtering pollutants such as formaldehyde, which can cause respiratory issues. This is an ideal low-maintenance house plant as it only needs re-potting once every one to two years.
