Firewall put to the test against COVID-19

Waterlogic’s patented Firewall technology has long been recognised for its ability to purify water up to 99.99% virus-free and 99.9999% bacteria-free. Firewall was rigorously tested against the human form of COVID-19 by a team of microbiologists from the University of Arizona led by Dr. Gerba, internationally known for his methodologies for pathogen detection in water and food.

"I have tested the Waterlogic Firewall machine and can confirm it removes COVID-19."

The world’s first COVID-secure range of UVC water coolers

Peace of mind guaranteed for the 50 million people around the world who rely on Waterlogic dispensers to provide safe and hygienic access to great-tasting drinking water.

How Firewall technology works:

Unprotected pipes expose water to the risk of being infected by viruses and bacteria from outside. Firewall disinfects the water from the mains supply by exposing it to a high dose of UVC radiation as it flows down then up through the unique double-helix spiral. Any pathogen present in the water is then deactivated, as its DNA gets permanently damaged and so it becomes harmless.

Firewall’s intense UVC light also acts as a powerful barrier, stopping viruses and bacteria from entering the system and sanitises the nozzle to prevent cross-contamination between users.

The Result:

Purified water on demand that’s safe and delicious to drink.
