The Problem

You're drinking plastic. Every single day.

A single plastic water bottle can release hundreds of thousands of microplastic particles into the water it holds. Switching to a "stainless steel" bottle feels like the obvious fix - until you take a closer look at what's actually touching your water.

Most "stainless steel" bottles on the market hide plastic where you can't see it: plastic-lined caps, plastic spout inserts, plastic gaskets, plastic threading. Every sip drags water across those surfaces. Every twist of the lid creates microscopic friction. Over months and years, that plastic ends up in you.

Microplastics have now been detected in human blood, lung tissue, breast milk, and placentas. The science is still emerging, but the principle is simple: a bottle that's supposed to protect you from plastic shouldn't contain any.

The Solution

Zero plastic. Anywhere. Period.

The InoXS™ was built around a single non-negotiable: no plastic touches your water. Ever.

The interior walls are food-grade 316 surgical stainless steel. The exterior is food-grade 304 stainless steel. The cap is solid 316 steel with a hollow construction - no plastic insert filling the inside, no plastic threading, no plastic spout. The only non-metal component anywhere in the bottle is the food-grade silicone gasket that creates the airtight seal.

This is what a truly plastic-free bottle looks like when you build it without compromise.

The hollow steel cap changes everything.

Pick up almost any "stainless steel" bottle and unscrew the cap. Look inside. You'll see a plastic disc, a plastic insert, or a plastic-lined chamber. That's where manufacturers cut corners - the cap is where plastic hides.

The InoXS™ cap is engineered as a fully hollow stainless steel structure. The threading is steel. The walls are steel. The contact surface is steel. The only thing that isn't metal is the food-grade silicone ring that seals the cap to the bottle - and silicone is not plastic.

🧪
Silicone is Not Plastic It's an inert, non-toxic, medical-grade material made from silica (sand). Used in surgical implants, baby bottle nipples, and pharmaceutical seals.
🛡️
No Leaching, No Shedding Silicone doesn't break down into microparticles the way plastic does. It won't leach chemicals into hot or cold liquids.
✨
Built to Outlast You Food-grade silicone holds its seal for decades without cracking, hardening, or degrading.
The Materials

316 inside. 304 outside. Both food-grade.

Not all stainless steel is equal, and we don't pretend otherwise. We use two grades, each chosen for its job.

316 Surgical Steel - Interior & Cap
The same grade used in surgical implants, pharmaceutical reactors, and marine equipment. 316 contains molybdenum, which gives it superior corrosion resistance and makes it exceptionally non-reactive. This is what touches your water.
304 Food-Grade Steel - Exterior
The same 18/8 grade used in restaurant kitchens, commercial brewing, and food processing equipment. 304 is incredibly durable and handles daily use, drops, and dishwashers without flinching. It never touches your water.
Vacuum Insulated

Double-wall insulation. Real temperature performance.

Between the 316 interior and the 304 exterior sits a vacuum chamber. No air, no conduction, no heat transfer. That's what keeps your water exactly the temperature you poured it.

FAQ

Common questions, straight answers.

Isn't every "stainless steel" bottle plastic-free already?
No. Almost every steel bottle on the market uses plastic in the cap - either as a liner, a threaded insert, or a sealing disc. Many use plastic spouts and plastic-coated paint on the exterior. The InoXS™ is one of the only bottles built without plastic anywhere in its construction.
The cap has a silicone seal. Isn't silicone just another plastic?
No, silicone is chemically distinct from plastic. It's made from silica (sand), not petroleum, and its molecular structure is fundamentally different. Silicone doesn't break down into microparticles, doesn't leach chemicals, and is used widely in medical implants and infant feeding products. Food-grade silicone is one of the safest sealing materials available.
Why 316 inside and 304 outside?
316 is the higher-grade steel - more corrosion-resistant, more inert, used in surgical and pharmaceutical applications. We use it everywhere your water touches: the interior walls and the inside of the cap. The exterior is 304, which is still food-grade and incredibly durable, but doesn't need 316's premium properties since it never contacts your water. This approach gives you surgical-grade purity where it matters and proven durability where it doesn't.
How long does it keep water cold or warm?
The double-wall vacuum insulation keeps cold water cold for up to 24 hours and warm water warm for up to 12 hours.
Is it dishwasher safe?
Yes. Steel and silicone are both dishwasher safe (top rack recommended). With no plastic parts, there's nothing to warp, melt, or degrade over time.
Can I use it for hydrogen water, hot tea, coffee, or anything else?
Yes to all of the above. The InoXS™ was engineered with hydrogen water in mind - because if a bottle can keep hydrogen molecules contained, it can handle anything. Cold water, hot beverages, infused water, electrolyte drinks. The inert steel and silicone won't absorb flavours between uses.
One Bottle. Zero Compromise.

For a no-microplastics life.

The InoXS™ is the only water bottle you'll ever need - and the only one that doesn't sneak plastic into your hydration when you're not looking.

    Why would I need an H₂ storage bottle if I can generate hydrogen water on demand?

    Because generation and consumption don’t always happen in the same place - or at the same time.

    The storage bottle protects your hydrogen so you can drink when it actually matters, not only when it’s convenient to run a cycle.

    So what’s the real purpose of an H₂ storage bottle?

    To preserve your hydrogen until the moment you actually need it.

    Generate anywhere.
    Drink anytime.

    Can I use it for other drinks?

    Absolutely.

    Unlike a generator, this is a true multi-use bottle.

    You can mix hydrogen water with:
    • Tea
    • Electrolytes
    • Juice
    • Coffee alternatives

    You’re not limited to plain water.

    Why not just take the generator outdoors?

    Hydrogen generators are precision electronics.

    They are:
    • Not rugged
    • Expensive to replace
    • Vulnerable to water, sand, cold weather, mud, or drops

    A stainless steel bottle is built for real life.

    It can take scratches, bumps, and outdoor conditions without risk.

    What are some other advantages over a hydrogen water bottle?

    1. Most hydrogen generators involve plastic contact surfaces.
    Repeated lip contact and handling can contribute to microplastic exposure.
    By transferring the hydrogen water into an all-metal storage bottle, you eliminate:
    • Lip contact with plastic
    • Friction wear
    • Ongoing microplastic risk
    It’s a cleaner interface for daily use.

    2. Generators typically produce smaller volumes per cycle.
    But real-life moments - like hiking or reaching a summit - demand more hydration.
    With a 1L capacity, you can:
    Drink a meaningful amount when you need it most - not just 9 oz at a time.

    3. Running a generator every hour at work can feel… noticeable.
    With a storage bottle:
    No one knows what you’re drinking.
    It looks like a quality water bottle - not a device.

    Is this bottle compatible with a standard car cup holder?

    Does it fit the standard car cupholder?
