How to Use Your Flavor Water Bottle

Get the most out of your portable water bottle with flavor adjustment

Choose Your Flavor Cartridge

Select from our wide range of flavor cartridges. Each cartridge is designed to provide up to 6 bottles worth of delicious, sugar-free flavor. Simply twist the cartridge into the bottle lid until secure.

Adjust Flavor Intensity

Turn the flavor dial on your bottle to control the intensity. Rotate clockwise for stronger flavor or counterclockwise for a lighter taste. The dial has 10 levels, allowing you to customize your hydration experience perfectly.

Fill and Enjoy

Fill your bottle with cold water for the best flavor experience. As you sip, the water flows through the flavor cartridge, infusing each drink with your chosen taste. The bottle is dishwasher safe (remove cartridge first).

Replace Cartridges Regularly

Each flavor cartridge lasts for approximately 6 full bottles or 132 ounces of water. When you notice the flavor weakening, it's time to replace the cartridge. Store unused cartridges in a cool, dry place.

Clean and Maintain

Clean your bottle regularly with warm soapy water. Remove the flavor cartridge before washing. The bottle body and lid are dishwasher safe. Replace the silicone seal every 3-6 months for optimal performance.
