General
FlavaFil is the world’s first all-in-one filtration and flavour enhancement straw that fits most standard water bottles. It filters out contaminants while letting you customize your hydration with teas, syrups, electrolytes, or flavour powders - without staining or scenting your bottle.
FlavaFil filters water as you drink and allows you to add flavor if desired. Water passes through the filter for purification, then through the FlavaChamber for optional flavoring. You can use it for filtration only, flavoring only, or both.
FlavaFil is designed to be universally compatible with most standard straw-cap water bottles ~ including Owala, Stanley, Hydro Flask and more. You can easily cut the universal connector straw to size to match your bottle perfectly.
The main components are dishwasher safe (top rack only). For manual cleaning, use warm, soapy water to clean the straw and FlavaChamber. Rinse thoroughly. The filter should not be washed - just replace it when needed.
We're currently in the pre-launch phase. You can reserve your FlavaFil with a $1 deposit and save 51% when we launch. Visit https://get.flavafil.com/to reserve.
We will be launching in Fall.
FlavaFil is the only product that filters and flavors water at the same time ~in a universal, modular straw that fits your favourite bottle. It usesNASA-level filtration and patented flavour control technology, so you get clean, flavored water without the mess or plastic waste.
Yes! FlavaFil is perfect for travel. Whether you're worried about water quality abroad or want to carry your favorite tea blend, FlavaFil keeps you hydrated safely and conveniently. We recommend using the MAX Filter for peace of mind while travelling.
No. FlavaFil is designed for cold or room temperature water only. Using hot water may damage the filter or FlavaChamber.
Yes! FlavaFil is a great hydration tool for kids. It encourages them to drink more water through flavor, without added sugar. Just make sure the filter and chamber are assembled correctly and not used with hot liquids.
Flavor
FlavaFil is designed to work with a variety of flavour formats, including cold brew teas, electrolyte and flavor powders, as well as flavored syrups. These different formats work depending on which insert you're using in the FlavaChamber. There are two insert options: the SwirlBullet and the Tea & Syrups Bullet ~ each tailored for specific flavour types.
Use this Bullet when you want to infuse your water with:
~ Cold brew tea bags (herbal, green, fruit, rooibos, etc.)
~ Loose-leaf teas (use the mesh layer provided to catch fine particles)
~ Flavoured syrups and cordials (including natural fruit syrups and concentrates)
The FlavaBullet is ideal for steep-style flavour release and syrup dilution as you sip.
Use the SwirlBullet when you're mixing:
~ Electrolyte powders
~ Flavour powders and granules
~ Vitamin or hydration drink powders
The SwirlBullet's internal spiral design helps distribute powders evenly as water flows through, creating a smooth, well-balanced sip without clumping or sediment.
Cold brew teas are tea bags specifically designed to infuse in cold water (no hot water needed!). They're the chill cousin of your regular tea bags, bringing smooth, refreshing flavor.
How it works: Pop a cold brew tea bag into your FlavaBullet, place it in the FlavaChamber, and enjoy instant flavor as you sip.
You can find cold brew tea bags at most grocery stores and tea shops. They come in tons of flavors, from classic black tea to fruity herbal blends, giving you endless options to customize your hydration experience.
Yes! FlavaFil is compatible with off-the-shelf cold brew tea bags. Simply roll it up and place inside the FlavaBullet. You can also use loose tea leaves if you desire.
FlavaFil uses a unique two-channel system inside the patented FlavaChamber to deliver clean, balanced flavor ~ without overwhelming your water.
As you sip, water flows upward through two paths:
1. One path moves through the flavour insert (either the Tea & Syrups Bullet or SwirlBullet), where it picks up flavor from tea, syrup, or powder.
2. The second path flows around the outside of the insert,, remaining unflavored.
At the top of the chamber, the flavoured and unflavored water meet and blend ~ giving you a perfectly balanced sip every time.
You can also control the intensity using the built-in FlavaControl dial, which adjusts how much water flows through the flavor insert versus around it. This gives you complete control over how strong or subtle your flavor is, without needing to shake or stir.
The result: fresh, customizable hydration in every bottle ~ with no lingering taste, no mess, and no wasted water.
Yes! FlavaFil features a dial mechanism called the FlavaControl that lets you control how much water flows through the FlavaChamber. Want a subtle hint? Turn it down. Want a bold blast of flavor? Turn it up. It’s hydration, personalized.
Yes! The Tea & Syrups is fully compatible with flavored syrups and cordials. It mixes them evenly as you sip, without leaving residue or staining your bottle.
We designed FlavaFil to be the optimal size to fit most water bottles, this means the amount of syrups and powders it can use is restricted, which affects the amount it can flavor. How long the flavor last or how quickly the powder dissolves caries according to your flavor setting preference. The stronger the flavor setting the less water it will flavor , the more subtle the flavor the longer it lasts.
As a rule of thumb powders dissolve between 9oz (250ml) and 12oz (350ml). Tea lasts the longest depending on the strength of the leaves 14oz (400ml) to 21oz (600ml). Syrups and cordial flavoring can last between 11oz (300ml) and 14oz(400ml)
No. FlavaFil’s flavor stays inside the FlavaChamber, meaning your water bottle remains clean, unstained, and free of residual taste ~ so you can switch from berry tea to lemon electrolytes without needing to rinse.
FlavaFil uses aVenturi system ~a narrow pathway that increases water speed and pressure, allowing flavour to be pulled through and mixed more effectively. This creates a smooth, natural blend without the need for shaking or squeezing.
Filter
We have made 2 filters for FlavaFil.
1: The DAILY filter uses carbon block technology and removes Chlorine, Chloramine and Lead. We made this filter because it has a good flow rate and sips easily while immediately improving the taste of your water as you sip. Chlorine is used to purify water because it kills just about everything harmful hat is in your water but to kill all viruses and bacteria in you drinking water but leave the water with an awful taste. Lead can be added to your water through outdate infrastructure in your home or from sources.
2. The MAX filter uses Ahlstrom Disruptor technology which was originally developed for NASA. this filter uses electroadsorptive filtration to remove just about everything from your water despite having a larger pore size for better water flow, including viruses, bacteria, pesticides, VOC particle class 1 and 2, and mechanically reduces tiny microscopic particles, like microplastics of up to 1.2 to 1.5 microns.
We didn't create the filter media we used to make our filter cartridges, we sourced them from the most reputable suppliers we could find, (Ahlstrom Disruptor is made in the US) thats their expertise not ours so best let them do what they do best ad we do what we do bets. This is to ensure quality and peace of mind for both you and us.
Of course we are busy with our own independent lab testing to ensure they do exactly what they say they can but specifically in our product.
Microplastics have been found in over 90% of global tap water ~ and they don’t just pass through the body harmlessly. Research suggests they can carry toxins, disrupt hormones, and cause long-term health effects. Because these particles are extremely small, most standard filters don’t catch them.
FlavaFil’s PurePlus™ filter is engineered with Disruptor™ technology, which is fine enough to trap even the tiniest microplastics ~ giving you cleaner, safer water in every sip.
The activated carbon membrane in FlavaFil is a key layer of the filter that targets taste, odor, and chemical pollutants. It works through adsorption, attracting and holding onto molecules like chlorine, chloramine, volatile organic compounds (VOCs), and some heavy metals.
Unlike basic filters that rely on mechanical separation alone, this membrane helps transform harsh-tasting water into a clean, crisp sip ~ perfect for pairing with any flavour you add. It enhances the quality of your base water, ensuring that your flavours shine through without interference.
Tap water often carries unpleasant tastes caused by chlorine, chloramine, and organic compounds. FlavaFil doesn’t just block those substances ~ it neutralizes them using an activated carbon layer, reducing their impact on both taste and smell.
This means your water tastes fresher, cleaner, and more natural ~ without the chemical aftertaste or “swimming pool” smell some tap water has.
Yes. The core filtration material in FlavaFil ~ Disruptor™ ~ was originally developed with support from NASA to help astronauts access safe water in space. It uses positively charged nanofibres to attract and trap negatively charged contaminants, while allowing clean water to pass through at a high flow rate. That same space-age innovation is now available in your everyday bottle.
Each filter lasts approximately one month. You'll know it’s time to replace it when the flow slows down or the taste changes.
