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.
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.
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.
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.
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.
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.
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.
Cleans Teeth Surfaces
A powerful water jet utilizing Nano Bubble Jet Plus technology enables removal of food debris stuck to the surface of the teeth.
Designed to Tackle between Teeth
Easily get between teeth to remove food debris with the powerful Nano Bubble Jet Plus.
Protect with Periodontal Pocket Cleaning
The Nano Bubble Jet Plus removes the bacteria in periodontal pockets that cause periodontal disease.
Cares for Your Gums
Designed with comfort in mind, Nano Bubble Jet Plus technology helps to gently stimulate your gums.
Works around Orthodontic Appliances
Washes away food debris in difficult to brush places such as between teeth, orthodontic braces and bridges.
Before
Even if you think you have thoroughly brushed your teeth, about 40% of food particles remain when cleaning with a toothbrush.
After
Irrigators can easily and effectively remove food debris and plaque, even in interdental areas that are very difficult to reach with a toothbrush.
Fast USB-C Cable*1 for 20 Minutes of Use*
A full charge takes just 3 hours using a USB-C cable1, delivering up to 20 minutes of use2. Simple, convenient charging keeps your device ready when you need it.
3 Adjustable Water Pressure Levels with Memory Function*
Choose from 3 water pressure levels to suit your gum sensitivity and personal preference. The device automatically remembers your last setting, so it’s ready to use exactly how you like it next time.
80 Seconds of Continuous Use*
A large 145 mL tank provides up to 80 seconds of continuous use, giving you enough time to complete a thorough clean without interruption or refilling.
Interdental Guide Mode for More Confident Cleaning
The water pressure automatically pulses to help guide your timing as you move the nozzle between teeth, making it easier to clean thoroughly and consistently.
