The COSLUS E40 Water Flosser is made for people who want a cleaner, more comfortable daily routine.

Its 10-level smooth pressure control helps you adjust the water flow to what feels right for you — from gentle daily cleaning to a deeper clean when you need it.

ADA Accepted, the E40 helps remove plaque and helps prevent or reduce gingivitis. It also helps clean hard-to-reach areas along the gumline, between teeth, and around braces, crowns, and implants.

With a 300mL large-capacity visible tank and 5 specialty tips included, the E40 is built to make daily oral care easier, more effective, and more adaptable.

This COSLUS E40 comes with a 2-year limited warranty.

Turn the Dial, Own Your Perfect Pressure

The COSLUS E40 gives you 10 levels of rolling pressure control so you can adjust your clean the way that feels best for you. Whether you prefer a gentler setting for comfort or a stronger stream for deeper cleaning, E40 helps you find your perfect pressure with less guesswork.

One Fill. All Clean.

With a 300ml visible water tank, the COSLUS E40 gives you more water for a smoother clean with fewer interruptions. No stopping halfway to refill — just a more convenient routine from start to finish. Its curved ergonomic design also fits more naturally in your hand, making daily flossing feel easier, steadier, and more comfortable to use.

Gentle on Sensitive Gums.

The COSLUS E40 delivers a more professional clean by helping remove what brushing can leave behind, especially around braces, along the gumline, and between teeth. ADA Accepted and designed to feel gentler on sensitive gums, it gives you a deeper clean without the harsh feeling that can make daily flossing uncomfortable.

One Flosser. More Ways to Clean.

With 5 replacement tips across 4 specialty tip types, the COSLUS E40 is designed to support more than one cleaning need in one device. From professional daily cleaning and sensitive gum care to braces cleaning and tongue care for fresher breath, it helps make oral care more practical for individuals and more convenient for the whole family.

Powerful When You Need It. Gentle When You Prefer It.

The COSLUS E40 lets you adjust between powerful and gentle levels for different parts of your day — from after meals and after snacks to your shower routine and a quick daytime refresh.
