Gentle on Gums. Powerful on Plaque
Advanced Nano Bubble Jet technology helps gently yet effectively remove sticky plaque and food debris from hard-to-reach areas between teeth and along the gumline. Powered by water vapour bubbles, it delivers up to 8x* more cleaning power than conventional models while remaining gentle on sensitive gums and everyday oral care routines.
* Compared to EW-DJ26 (tested by Panasonic).

Features
Oral Care That’s Tough on Plaque*, Not Gums
Nano Bubble Jet Plus cleans without relying on high water pressure. Instead, it uses micro-droplets and nano-sized bubbles that burst in the water stream, helping lift away plaque gently and effectively.
* Sensory evaluation compared to EW-DJ86/EW-DJ66 at level 3 water pressure.
Boosted Cleaning Performance*
Cleaning performance* isn’t determined by water pressure alone. It depends on the right balance of water pressure, the number of bubbles in the water stream, and how easily those bubbles burst - working together to improve overall cleaning effectiveness.
*Cleaning performance based on simulated stain removal. Tested by Panasonic.

Stronger Cleaning Power, Gentle on Gums*
Nano Bubble Jet Plus delivers up to 8x the cleaning power of our conventional model (EW-DJ26), while remaining gentle on gums. This is achieved by precisely controlling the number of bubbles in the water stream and how easily they burst, improving cleaning effectiveness without increasing water pressure.
*Cleaning performance based on simulated stain removal. Tested by Panasonic.

Powerful Water Flow, Gentle on Gums*
Air Charger technology infuses air into the water stream to deliver effective cleaning without relying solely on high water pressure. This helps maintain strong cleaning performance while remaining gentle on gums.

Number of Bubbles Contained in the Water Stream
Air-Infused Water for a More Effective Clean
Air Charger technology mixes air into the water stream by reversing water flow, helping enhance cleaning performance where it’s needed most. This creates a stronger yet controlled cleaning action without relying solely on water pressure.

More Air for a Gentler, More Effective Clean*
Nano Bubble Jet Plus delivers 15.3 times* more air in the water stream compared to our conventional model, helping create a gentler yet more effective cleaning experience. This increased air content supports improved plaque removal while maintaining comfort on gums.
*With EW-DJ26 (conventional model) set at 100. Tested by Panasonic.

Enhanced Cleaning Through Nano Bubble Action*
The Double-Neck Nozzle uses an internal compression chamber to combine air and water, creating fine nano-sized bubbles. As these bubbles burst in the water stream, they help lift away plaque for a more effective clean.
*Cleaning performance based on simulated stain removal. Tested by Panasonic.
