If the FlavaFil is the heart of your hydration system, the FlavaChamber is the soul. This is where science and creativity meet, where flavor joins your flow, and where you get to take control of exactly how your water tastes. The FlavaChamber is designed to keep flavor separate from your bottle so your bottle stays clean, your flavors stay fresh, and your options stay wide open.
In this guide, you will learn what the FlavaChamber does, the different Bullets it uses, and exactly how to load each type for the perfect sip.
Step 1: What the FlavaChamber Does
Think of the FlavaChamber as a mixing studio for your drink. It is where the water flowing through your straw meets your chosen flavor. Thanks to the Venturi effect, water is drawn past the Bullet and flavor is pulled smoothly into the stream. You get a consistent taste from first sip to last without shaking, stirring, or mess.
Because the flavor never touches the inside of your bottle, you can switch from lemon tea to vanilla cold brew without lingering scents or stains. That also means cleaning is faster and easier.
Step 2: Meet Your Flavor Bullets
The FlavaChamber works with two main Bullet types, each designed for a specific category of flavors:
SwirlBullet for Powders and Electrolytes
This has a casing with small holes and an internal swirl design. It helps powders dissolve evenly as water flows through. It can hold about 0.4 oz (11 g) of powder.
Teas & Syrups Bullet
This has a casing without holes and uses a FunnelCap. It is perfect for liquids like syrups and for cold brew tea bags. For loose leaf teas, you can add the optional tea mesh insert.
Each Bullet locks into the FlavaChamber so it stays in place as you sip.
Step 3: Preparing the FlavaChamber
Before adding flavor, make sure your FlavaChamber is ready:
~ Insert the Duckbill Valve into the chamber with the slit facing downward. This ensures one-way flow and prevents leaks.
~ Attach the silicone connector tube to the neck of the chamber casing.
~ If using a filter, attach the FilterChamber to the connector tube. If you are not filtering, use the Carbonated Straw instead.
Once assembled, your FlavaChamber is ready to load with flavor.
Step 4: Loading Powders and Electrolytes
The SwirlBullet is designed for any powdered flavor or supplement. Here is how to load it:
~ Drop the SwirlBullet casing into the FlavaChamber. Twist gently until it falls into position.
~ Add your powder directly into the casing, distributing it around the internal swirl.
~ Clip the cap onto the Bullet.
~ Align the marker on the FlavaChamber cap with the raised area on the BulletCap. This will line up with the flavor indicator markings.
~ Twist to your chosen setting.
Recommended settings:
~ Level 2 or 3 for full flavor release.
~ Powder will typically dissolve completely in 10–14 oz (300–400 ml) of water per serving.
Step 5: Loading Syrups and Cordials
The Teas & Syrups Bullet works perfectly for liquid sweeteners and concentrated syrups.
~ Place the Bullet casing into the FlavaChamber and twist until it clicks into position.
~ Pour syrup into the Bullet until it is full.
~ Add the cap to seal the Bullet.
~ Align and twist the FlavaControl dial to your desired level.
Recommended settings:
~ Level 1 or 2 for a balanced taste.
~ Syrup flavor typically lasts 10–12 oz (280–340 ml) per serving.
Step 6: Loading Cold Brew Tea Bags
Cold brew tea bags work best in the Teas & Syrups Bullet with the FunnelCap.
~ Remove the tag from the tea bag.
~ Fold or roll the tea bag so it fits directly into the FunnelCap.
~ Fit the cap into the Bullet casing.
~ Insert the Bullet into the FlavaChamber and twist to lock.
Set your flavor level.
Recommended settings:
~ Level 1 or 2 for the longest-lasting flavor.
~ Tea bag flavors last 13–16 oz (370–450 ml) per serving.
~ Allow 1–2 minutes after your first sip for the flavor to steep fully. This is what we call the Actiwait.
Step 7: Loading Loose-Leaf Tea
For loose-leaf tea, you will use the mesh insert to hold the leaves in place.
~ Insert the mesh into the Bullet casing.
~ Clip the cap into place over the mesh. It will only fit in one position so do not force it.
~ Invert the meshed cap and fill with tea leaves to about three-quarters full.
~ Close the Bullet casing over the cap with the leaves inside.
~ Insert the Bullet into the FlavaChamber, twist to lock, and set your flavor level.
Recommended settings:
~ Level 1 or 2, with a maximum of Level 2 when using the mesh.
~ Allow 1–2 minutes for flavor to steep before sipping.
Step 8: Setting Your Flavor Level
The FlavaControl dial is your way of telling the FlavaChamber how bold you want your drink.
~ Level 1 is a gentle hint of flavor.
~ Level 2 is balanced and refreshing.
~ Level 3 is strong and energizing.
The dial adjusts the opening size in the FlavaChamber, letting more or less flavor mix with each sip. Because the Venturi effect blends flavor as you drink, you will notice a smooth taste every time.
Step 9: Cleaning After Use
To keep your FlavaChamber performing at its best:
~ Disassemble the chamber and remove the Bullet after each use.
~ Rinse all parts under running water or place them on the top rack of your dishwasher.
~ For tea mesh inserts, remove and rinse thoroughly to avoid build-up.
Never put the filter in the dishwasher or clean it with detergents. Rinse under running water only.
