That depends on which mouthpiece your air up® bottle has. There are two types:

🟢PullUp Mouthpiece Often found on Twist bottles, and sometimes on Twist Pro or Twist Pro Steel — depending on your version.

• Flavor ON: Slide the pod onto the mouthpiece and pull it upwards. Pod up = flavor ON.

• Flavor OFF: Push the pod downwards until it stops. Pod down = plain water.

• Feature:

  One line on the mouthpiece

🟢 ActiveOn Mouthpiece Often used in newer bottles like Twist Pro, Twist Pro Steel, and Click. This version was designed for more convenience — it activates the pod automatically when you open the lid. Functionally, it works the same as PullUp.

• Flavor ON:

  The pod is already ON when you open the lid. Just sip and enjoy!

• Flavor OFF:

  Gently pull the pod upwards — this turns the flavor off. It’s the reverse of the PullUp version.

• Features:

  Two lines close together + two bumps inside the mouthpiece
