What is a Pure Air Zone?

At its simplest, more than 90% of contaminants do not respond to traditional ventilation or gravity. They are just too small. U-Earth’s Pure Air Zone biotechnology changes all that.


The AIRcel bioreactor uses an electrostatic charge formed from water and electricity to attract charged contaminants of any type or size. It’s a physics principle known as molecular charge attraction.


Once inside, the contaminants are neutralised using U-Ox, a patented blend of enzymes and bacteria from the natural world. The outcome is a dash of CO2 (less than the average house plant), some residue and Pure Air, which returns to the environment for you to enjoy.

Each AIRcel can also be tested for SARS-CoV-2, the virus responsible for Covid-19. A simple check of the water can ensure that the air that you are breathing is as safe as possible so that you can completely relax and enjoy your meal.


  • 13% of London’s particle pollution is caused by restaurants.

  • Indoor air quality is 2-5x worse, on average, than outdoors.

  • According to WHO, 91% of people live in an area with unsafe air.

U-Earth is working to change this.

We also offer U-Mask, a biotech face mask, used by multiple teams in Formula 1 and MotoGP. You can buy U-Mask online or why not visit U-Store, our flagship store in London? It is also a Pure Air Zone so that you can begin breathing the future today.
