Why the E40: Designed to Make Daily Oral Care Easier to Keep Up With
For years, water flossing has come with a small but familiar moment of hesitation. Standing at the sink, water running, users glance down to find the right setting, wondering if the next adjustment will be too strong, too weak, or send water splashing everywhere.
Professional Clean. Your Way.
The E40 was designed to make that moment simpler.
Its design keeps users focused on care, not controls, with every detail made for easy, whole-family use.
● Turn the dial, own your perfect pressure.
Its intuitive 10-level dial pressure control makes pressure adjustment simple, precise, and easy to control.
● One fill. All clean.
The large, visible 300 mL water tank enables one continuous clean without refilling.
● One Flosser. Multi-Clean.
Paired with 5 specialty tips, including a tongue-cleaning tip, the E40 helps clean between teeth, along the gumline, and on the tongue for a fresher-feeling routine.
● Gentle on sensitive gums.
Its dial-based control lets users start gently and adjust comfortably, making the E40 suitable for first-time users and those with sensitive gums.
