      • A. One Cirkul flavor cartridge (also called a “Sip”) flavors about 132 ounces of water, depending on the flavor dial setting. With a 22oz Bottle that is about 6 fill ups. With a 12oz bottle that is about 11 fill ups. With a 32oz Bottle that is about 4 fill ups.

    • Q. Does the Cirkul lid only work on the Cirkul bottle?
      • A. We're partial to our bottle, but we understand that you might have one you know and love. That's why we designed our lid to work with the Cirkul bottle and also many other wide-mouth water bottles including Nalgene, CamelBak, Contigo, Hydro Flask, and Klean Kanteen.*

    Bottle & Lid

    • Q: How many ounces is the Cirkul bottle?
      • A: You have your choice of 4 Bottle sizes! 12oz, 22oz, 32oz, and 42oz.
    • Q: My lid or bottle squeaks, help!
      • A: Not to worry, that's just an audible reminder of all the hydrating you're doing! All kidding aside, the air valve located on the top of the lid (which balances the pressure in the bottle) can sometimes squeak when you first receive it. After a few bottles it should stop. A cycle through the dishwasher (top rack only) also seems to help. It's one of those quirks that come with new products and we're working hard to get rid of it! If you have any questions please reach out to us at
    • Q: Does the Cirkul bottle fit in my car cup holder?
      • A: Yes, most car cupholders can accommodate the 12 oz and 22 oz Bottles. However, since all vehicles are different you may need an extender for the 32 oz & 42 oz Bottle.
    • Q: Does the water in my bottle have flavor left in it from the Cirkul Sip?
      • A: Cirkul's patented technology contains a one way valve that prevents any back flow from the Sip into the Bottle. Feel free to switch flavors in and out with the same water in your Bottle.
    • Q: Can I use a Cirkul Sip on a different lid?
      • A: Cirkul Sips are only compatible with Cirkul Lids.
    • Q: Can I use Cirkul Sips with a different bottle?

    • Q: Can I use sparkling water in my bottle?
      • A: Cirkul Sips can be used with plain or sparkling water.
    • Q: Is my bottle dishwasher safe?
