LONDON (CBSNewYork) — It is a literal breath of fresh air in the heart of busy London.

A new bar and its sea of green is giving customers a break from the toxins outdoors.

“The only real product that can viably remove those compounds, those nasty things in the air, are these lovely things – plants,” says botanist Freddie Blackett.

Blackett, who based his selections on NASA research, says the plants can absorb up to 85 percent of harmful gases.

The concept of The Clean Air Bar is simple: give people a chance to unwind around lush vegetation and cleaner air.

“There’s so much pollution in London,” says customer Peggah Kamali, “so the opportunity to get some fresh air, while you have a drink just make it that much more enjoyable.”

The pop-up bar isn’t just about improved air quality. A garnish wall adds a bit of fun for drinkers to customize their cocktails.

“We’ve got some fresh mint, and some basil here,” says Kate Jackson, a Ketel One brand ambassador.

It’s a small way to spice up a summer drink and perhaps provide inspiration, too.

“I hope that when people come to a place like this, that they enjoy things like the garnish wall…that they think this is something I could recreate at home,” says Blackett.

Environmentalists hope the concept will grow to other big cities around the world.
