Flavor cartridges

Cartridges are the heart of the system, and each one adds a flavor that blends into plain water as you drink. Flavor strength can be adjusted, so you can start light and move up as your taste changes. The variety of flavors gives everyday drinkers a way to enjoy more water without turning to sugary drinks. Each cartridge slots into the bottle with a simple twist and is ready to use straight away.

Bottle materials

Bottles come in plastic and stainless steel options, and the lids are designed to hold the cartridge in place during use. The bottles are made without BPA, which suits buyers who want a reusable bottle for daily carrying. Tumblers give a different feel for desk or home use. Choosing between materials often comes down to weight, feel and how the bottle will be carried. Each option feels different in the hand, so trying one in person helps.

Daily use and taste

Reviewers say the bottles work well for building a steady habit of drinking water through the day. Flavor strength can be dialed up or down, which helps with taste preferences that shift over time. Regular cleaning keeps the bottle and cartridges fresh, and rinsing after each use is a simple habit that keeps flavors clean from one refill to the next. Keeping the cartridges fresh with timely cleaning means each flavor tastes as intended.

Our full take

Reusable water bottles with adjustable flavour cartridges. The range includes plastic and stainless steel bottles, tumblers, flavour cartridges and starter kits.
