One of the most powerful parts of your FlavaFil is something you can see and feel right at the top of your straw: the FlavaControl dial. This is the small but mighty tool that puts you in control of your hydration experience. With a simple twist, you decide exactly how much flavor enters your sip. No more guessing, no more “too strong” or “too weak” moments. Just your drink, your way.
In this guide, we will walk you through what the dial does, how it works, and how to use it to create the perfect drink every time.
Step 1: What the FlavaControl Dial Does
The FlavaControl dial is connected to the FlavaChamber, where your flavor Bullet sits. As you turn the dial, you adjust the size of the opening that allows flavored liquid to mix with the water flowing through your straw. A larger opening lets in more flavor, while a smaller opening keeps it subtle.
Because of the Venturi effect, the flavor mixes evenly with the water as you sip. That means no clumps, no uneven bursts of taste, and no need to shake or stir. Every sip has the same flavor intensity from start to finish.
Step 2: Understanding the Flavor Levels
The dial is marked with three settings. Each one changes the personality of your drink.
Level 1
The lightest touch of flavor. Perfect for syrups or cordials when you want a hint without overpowering the taste of your water. It is also ideal for cold brew teas when you want the flavor to last longer.
Level 2
A balanced, refreshing middle ground. Great for cold brew teas, loose leaf teas, or lighter electrolyte mixes. This setting gives a noticeable flavor without being too intense.
Level 3
Full burst. Designed for strong flavor delivery, especially for electrolytes, sports drinks, or when you want a bold taste that hits right away.
Step 3: Matching the Setting to Your Flavor Type
Different flavors work best at different settings.
~ Powders and Electrolytes: Level 2 or 3. Powders dissolve more completely when more water flows through the Bullet.
~ Syrups and Cordials: Level 1 or 2. Concentrated liquids can be very sweet, so lower settings help balance them.
~ Cold Brew Tea Bags: Level 1 or 2 for the longest lasting flavor.
~ Loose Leaf Tea (with mesh insert): Level 1 or 2, never above Level 2 to avoid clogging the mesh.
Step 4: Adjusting the Dial
Adjusting the dial is simple, but there are a few tips to get the best performance.
~ Hold your FlavaFil by the FlavaCap or the bottle lid to keep it steady.
~ Turn the dial clockwise to lower the flavor level.
~ Turn the dial counterclockwise to increase the flavor level.
~ Listen and feel for a soft click as it passes each setting. This tells you the dial is aligned properly.
~ You can adjust the dial at any time, even mid-drink. If you start at Level 2 and want a stronger taste halfway through, simply twist to Level 3 and continue sipping.
Step 5: Fine-Tuning for Your Bottle and Sip Style
Your bottle size, water temperature, and sipping pace all affect flavor delivery.
~ Bottle Size: Larger bottles may need a higher setting to maintain the same flavor strength.
~ Water Temperature: Cold water tends to release flavor more slowly, so you may want to increase the setting for iced drinks.
~ Sip Speed: If you take long, slow sips, a lower setting may be enough. For quick, deep sips, you might prefer a higher setting.
Step 6: Conserving Flavor
If you want your flavor to last longer, start at a lower setting and increase it later in the day. This is especially useful for teas and syrups, where the flavor concentration in the Bullet decreases over time. Lower settings help stretch your flavor across more ounces.
Step 7: Troubleshooting Common Issues
If your flavor feels too weak, even at a higher setting:
~ Make sure the Bullet is seated correctly inside the FlavaChamber.
~ Check that your filter or Carbonated Straw is fully connected and not blocking the flow.
For powders, shake the bottle gently before your first sip to help start the dissolving process.
If the flavor is too strong at the lowest setting:
~ Reduce the amount of syrup or powder you load into the Bullet.
~ Try starting with more water in your bottle before adjusting the dial.
Step 8: Cleaning the Dial
Over time, the dial and its connection points can collect residue from your flavor Bullet. To keep it working smoothly:
~ Disassemble the FlavaChamber and remove the Bullet.
~ Rinse the FlavaCap and dial area under running water.
~ If needed, use the straw cleaning brush to gently scrub around the dial’s edges.
~ Dry before reassembling to maintain a smooth twist.
Why the FlavaControl Dial Matters
Without the dial, you would be locked into a single flavor intensity. That might work for some drinks, but hydration should be personal. The FlavaControl dial makes it easy to adjust on the fly. It turns your water into a customizable experience that matches your mood, your activity, and your taste.
This is part of what makes FlavaFil different from other hydration products. We did not just design a filter straw. We designed a system that puts you in charge.
