Your electrolyte ratio, dialed in.

Electrolytes only work when they’re diluted right. The FlavaFil SwirlBullet helps mix your electrolytes more evenly through each sip ~ giving you better control over your dose, no matter your bottle size or how often you refill.

And because it stacks directly above your filter, you’re getting cleaner-tasting water plus a smoother electrolyte mix in the bottle you already own.

Less mess. Less clumps. More control in every sip.

FlavaFil Fans Are Losing It

Turns out, people get really excited about better-tasting water. Here’s what they’re saying about FlavaFil

Savannah G.

USA

I love to add flavoring to my water. I own a Cirkul, but I like the idea of using my own flavoring AND my Owala.

Josh P.

USA

Such a smart idea! I’ve been looking for a product that can store my Mio/flavoring without staining my cup. This is going to be Epic!

Sally M.

USA

Love the idea of being able to use this in any water bottle or even cup to filter my water no matter what I’m using or where I am, and flavor my water, without staining or leaving flavors or scents behind

Craig C.

USA

I really like my Cirkuls concept but not really the flavors. Being able to fully customize my drink is the perfect option for me

Jo D.

USA

I am always looking for ways to drink more water. I am terrible at it, but flavor helps. I don't like putting flavor directly in my bottle because it sometimes gets gross and dirty. This might help with that.

Mandy N.

USA

It's a product that actually fulfils a need that I as well as others can effectively use without requiring ongoing purchasing of additional “proprietary” cartridges that don’t work with products that aren’t practical for our specific needs.

Kaelyn S.

Very neat product that doesn’t make you buy a new water bottle for filtration. It is also multi function do different uses on top of filtration

FAQs

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.

Once we have delivered our Kickstarter pledges, FlavaFil will be available online. You can still back FlavaFil on Kickstarter to be one of the first to get yours!

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 uses NASA-level filtration and patented flavour control technology, so you get clean, flavored water without the mess or plastic waste.
