The Thames Clipper that was turned into a Fresh Air Zone for the day.

Inside the Fresh Air Zone.

Throughout the boat, healthy plants were installed, much to the delight of passengers.

Different plants were used to show just how easy it is to decorate a space with displays that both look the part and clean up the air.

Peace Lilies were chosen because they are nature's natural air freshener - they're one of the best plants when it comes to purifying the air, whilst also emanating a pleasant fragrance.

Even the coffee bar was given a plant makeover with this fabulous Phalaenopsis Orchid.

The boat looked the part and put a smile on the faces of commuters!

Every passenger was given a free peace lily to take away at the end of their journey. Over 3,000 were given away during the stunt.
