COSLUS E40 Earns ADA Seal of Acceptance, Advancing Clinically Proven At-Home Oral Care！

On July 1,2026, COSLUS reached an important milestone in that pursuit.
Our water flosser, COSLUS E40, has earned the American Dental Association (ADA) Seal of Acceptance, one of the most respected certifications in oral health care. In addition, three COSLUS water flosser models C20, C50, and C51 also received ADA certification under the same evaluation framework.

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 you 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.

The ADA Seal of Acceptance confirms that COSLUS E40 meets strict standards for safety, effectiveness, and supporting clinical evidence.

• For users, this recognition provides confidence that daily oral care is backed by professional standards.
• For dental professionals, it reflects a level of performance and responsibility they trust.
• For COSLUS, it reinforces a long-term commitment to professional oral care.

According to ADA-Accepted clinical data, COSLUS E40 demonstrates meaningful improvements in gum and oral health, including:

• Helps prevent or reduce gingivitis.
• Helps remove plaque.

Earning ADA recognition is not an endpoint for COSLUS it is a direction.

As we continue to design products that align everyday care with professional expectations, E40 stands as a blueprint for what modern, intuitive, and clinically validated oral care can be.
