Plants have exploded in popularity in the past years, but this means that the plant market has become saturated. Plant Drop is an online plant retailer, but they face stiff competition. They needed a way to set themselves apart from the competition and steal market share, whilst also encouraging people who have never considered houseplants to see the value they bring.

Plants have air-purifying properties. This was proven way back in the 80s when NASA conducted research to see if plants could help clean the air for astronauts living in the International Space Station. This data was declassified years ago, but nobody has truly done anything with it. Many plant retailers advertise their plants as ‘air-purifying’ - but never go into detail about how specific plants can purify the air in our homes.

The air inside our homes can be up to 5x more polluted than outside, with toxins coming off everyday items like paint, scented candles & cleaning products. The NASA ‘Clean Air Study’ was conducted in 1989 and discovered that some everyday house plants had the ability of removing harmful toxins from the air. The study was declassified data, however, for the average person it was impossible to decipher and understand. Partnering with the lead botanist at Oxford University, Chris Thorogood, we crunched the data, built upon the research, and reimagined it into something entirely new.

Taking inspiration from the ‘Energy Rating System’ for appliances, we created the ‘Pollutant Absorption System’ for plants – a simple design key that categorises house plants based on their ability to scrub the air of harmful toxins.

Partnering with the lead botanist at Oxford University, Chris Thorogood, we crunched the data, built upon the research, and reimagined it into something entirely new.

We broke down complex science into something everyone could understand – pulling out the 5 main toxins that can be found around the home and making people aware of where they come from. For instance, the harmful chemical Benzene if often found in paint and cigarette smoke, whilst ammonia normal emanates from cleaning products.

This enables us to target consumers based on their lifestyle, via a new online tool that re-invented the plant shopping experience.

Inspired by the ‘Energy Rating System’ for household appliance, we created the ‘Pollutant Absorption System’ for house plants. Complex NASA data detailing plant variants and the toxins they can help remove was distilled down into a simple, easy-to-understand key. The design system fused together the design language of molecule structures with the visual aesthetic of plants and educated people about the 5 main toxins found in the home, and what items give them off.

The ‘Pollutant Absorption System’ changed the way consumers shopped for plants. Instead of buying plants based on looks, they now bought plants based on their lifestyle. If they had recently painted or smoked, they could opt for the Red-edged Dracaena, as it has the power to remove benzene from the air. Alternatively, if they had pets, they could buy the Weeping Fig as it helps remove xylene, a toxin given off by flea treatments.

The Pollutant Absorption System democratised clean air data for the masses – breaking down thousands of data points into an easy-to-understand system. Consumers now had a better understanding about the toxins inside their homes and could now buy plants based on their lifestyle and living arrangements instead of just looks.

- 64% increase in web traffic since launch.

- 45% increase in sales.

- 50% of customers buying more than one plant

Plant Drop believe that everyone should have the right to breathe clean air. So the Pollutant Absorption System was made open-source and free to download online for other plant retailers to adopt and integrate into their own e-commerce sites.
