So, you’ve got your FlavaFil in hand.
You’re ready for clean, delicious, personalized hydration. But before you start dialing up that peach tea or mixing up your post-workout electrolytes, you need to know one thing: how to put this beauty together so it works like a dream.
We’ve made FlavaFil modular for a reason ~ so it fits your bottle, your flavor, and your flow. But that also means there are a few parts to get to know. Follow along and you’ll be sipping like a pro in minutes.
Step 1: Meet Your FlavaFil
Your kit comes with everything you need to filter, flavor, and fit your favorite bottle. Inside the box, you’ll find:
~ FlavaFil Straw
~ FlavaBullet for Teas & Syrups (no holes, funnel cap, optional tea mesh)
~ SwirlBullet for Powders & Electrolytes (holes in casing, swirl design)
~ DAILY Filter (already included)
~ Two Universal Silicone Straws:
-
-
Green Straw (push-over connection, 0.35in / 9mm)
-
White Straw (push-in connection, 0.39in / 10mm)
-
~ FreeFlow Straw (for use without filter)
~ Filter Replacement Straw
~ Straw Cleaning Brush
~ Mesh Carry Bag
We engineered every component for a purpose ~ and by the end of this guide, you’ll know exactly what each one does.
Step 2: Choose Your Straw Fit
Bottles aren’t one-size-fits-all, so we’ve given you two silicone straw options.
~ If your bottle’s lid uses a push-over fitting, grab the green straw.
~ If it’s a push-in fitting, go for the white straw.
Pro tip: Hold your original straw next to the FlavaFil straw and cut to match the length. This keeps your flow smooth and avoids awkward tilting mid-sip.
Slide one end of the silicone straw firmly over the FlavaCap. On the other end, push it into or over your bottle lid fitting as far as it will go. Test the connection ~ if you can hold the lid and let the straw hang freely, you’ve nailed the fit.
Step 3: Assemble the FlavaChamber
The FlavaChamber is your flavor command center. It’s where your Bullet sits, where flavor meets flow, and where the Venturi effect works its magic.
Duckbill Valve: Drop it into the FlavaChamber with the slit facing downward. This ensures a smooth one-way flow.
Connector Tube: Slide the silicone tube onto the neck of the chamber casing until it feels snug.
FreeFlow Straw:
~ For unfiltered water: Attach the FilterChamber to the bottom of the connector tube.
~ For already filtered water or fizzy drinks: Use the FreeFlow Straw instead.
~ Insert the Filter: Twist and press your chosen filter into the FilterChamber until you feel resistance. It might sit slightly off-center ~ that’s normal.
Step 4: Assemble the FilterChamber
This step locks your filter in place.
~ Place the FilterCap on the FilterChamber.
~ Press down firmly until it clicks.
~ For a perfect seal, press your thumb on the FlavaFil logo at the back of the cap.
Note: The DAILY Filter is perfect for everyday tap water, while the MAX Filter is your go-to for travel or questionable sources. Both have been independently tested to NSF/ANSI standards for taste improvement and contaminant reduction.
Step 5: Load Your Flavor
Here’s where the fun begins.
For Powders & Electrolytes: Use the SwirlBullet. Fill with about 0.4oz (11g) of powder, clip on the cap, and drop it into the FlavaChamber. Twist until it settles into place.
For Syrups: Use the Teas & Syrups Bullet. Pour in your syrup, cap it, and drop it in.
For Cold Brew Tea Bags: Fold or roll your tea bag to fit into the FunnelCap, cap it, and load into the chamber.
For Loose Leaf Tea: Use the mesh insert to keep leaves in place. Fill to about three-quarters, cap it, and drop it in.
Step 6: Set Your Flavor Intensity
Your FlavaControl dial is where you decide how bold you want your flavor:
1 ~ Light & breezy, perfect for syrups.
2 ~ Balanced and refreshing, great for teas.
3 ~ Full-on burst, ideal for electrolytes.
The dial works by adjusting the opening size, letting more or less flavor mix into your sip. Thanks to the Venturi effect, it blends evenly without stirring or shaking.
Step 7: Sip, Smile, Repeat
Once everything’s in place, pop your FlavaFil into your bottle, fill with cold or room temperature water, and start sipping. You’ll notice:
~ Smooth flow thanks to optimized fluid dynamics.
~ Consistent taste from first sip to last.
~ No bottle staining or lingering smells because flavor never touches the bottle itself.
Step 8: Cleaning & Care
~ To keep your FlavaFil in peak condition:
~ Disassemble into all loose parts after use.
~ Use the straw cleaning brush to run through the Duckbill Valve and straw.
~ All parts except the filter are top rack dishwasher safe.
For filters, just rinse under running water to remove any residual carbon dust ~ never use detergents or dishwashers.
Why Assembly Matters
We designed FlavaFil to work seamlessly only when everything is fitted correctly. A poorly seated filter can reduce performance, a misaligned Bullet can affect flavor flow, and a loose straw connection can lead to leaks. The five minutes you spend setting it up right the first time will reward you with perfect hydration every time.
