COSLUS E40 Featured in TechTimes: Adjustable Pressure for Everyday Water Flossing
COSLUS is gaining attention for its approach to personalized oral care. On October 29, 2026, TechTimes featured the COSLUS E40 Water Flosser in an article titled “COSLUS E40 Brings Adjustable Pressure to Everyday Water Flossing,” highlighting its 10-level pressure dial, user-focused design, and commitment to making daily water flossing more convenient.
The feature reflects an important part of the COSLUS philosophy: effective oral care should fit into people's everyday lives, not the other way around.

The dial comes first
TechTimes puts the E40’s rotary pressure dial at the center of its story. Instead of cycling through preset intensities with repeated button presses, you turn a physical dial to choose among 10 pressure levels — a direct, one-handed adjustment that the article describes as the product’s defining feature. One-touch start keeps the rest of the routine simple.
The coverage also makes a point we agree with: ten levels are about choice, not about maxing out. The right setting is the one that feels comfortable and matches your dentist’s guidance. If you want a deeper look at how the dial performs day to day, see our COSLUS E40 review.
Shaped by feedback from U.S. users
As TechTimes reports, the current E40 reflects qualitative research COSLUS conducted in 2026 with 18 consumers across Los Angeles, Houston and New York, along with interviews with eight dentists. The refinements that came out of that feedback include an updated control panel and exterior finish, transparent tips for better visibility, a thicker periodontal tip, tip materials upgraded to PCTG, dedicated tip storage, and refreshed packaging.
Two modes, five specialty tips
The article walks through the E40’s two cleaning modes — Floss Mode and Massage Mode — and the five tips in the box: two standard jet tips, an orthodontic tip for cleaning around braces, a periodontal tip for the gumline, and a tongue-cleaning tip. Together they cover daily interdental cleaning, after-meal cleanups and care around orthodontic appliances. New to water flossing?

What ADA Acceptance means
TechTimes also explains the E40’s ADA Acceptance: the E40 carries the American Dental Association’s Seal of Acceptance, awarded to products that meet the ADA’s safety and efficacy requirements. The accepted claims are that it helps remove plaque and helps prevent and reduce gingivitis when used as directed. We covered the announcement in detail when the COSLUS E40 earned the ADA Seal of Acceptance.
Built for everyday routines
Rounding out the coverage are the practical specs: a 300mL tank sized for a full daily clean, up to 30 days of battery life per charge, and an IPX7 waterproof rating — in a cordless body that works as easily in a hotel bathroom as it does at home.
