What is UFBDUAL™️?
The UFB DUAL™ is the only ultrafine bubble generator nozzle in Japan certified as a water supply device, thanks to its patented technology. Unlike products designed for specific uses like bathtubs, showers, or washing machines, UFB DUAL™ is installed at the main water valve, transforming the entire building’s water supply into ultrafine bubble water. This unique feature sets it apart, providing a comprehensive solution for all water outlets within the structure.

What is UFBDUAL™️?

Key Features and Benefits

Transforms all building water into ultrafine bubble water
By installing UFB DUAL™ at the main water valve, ultrafine bubbles are generated using only the natural water pressure, converting all the water within the building into ultrafine bubble water.

Hygienic design with no external air intake
UFB DUAL™ creates ultrafine bubbles using only the air dissolved in clean tap water, without introducing external air. This structure eliminates the risk of bacteria or viruses, ensuring maximum cleanliness.

Special structure that maintains water volume and pressure
Conventional nozzle-based fine bubble generators are known to reduce water pressure and volume. However, UFB DUAL™ overcomes this issue with its patented DUAL structure, minimizing pressure loss and allowing it to achieve certification as a water supply device in Japan.

Maintenance-free
With its highly durable structure, UFB DUAL™ requires no special maintenance after installation. It begins working immediately and provides ultrafine bubble water continuously without the need for ongoing upkeep.

Easy installation and no external power required, with no running costs
UFB DUAL™ is easy to install and operates solely on the water pressure from the tap. It does not require any external power sources like electricity, meaning there are no ongoing running costs.
