The QuBottle Evidence Center
Written by the QuBottle team · Last reviewed:
We don't ask you to trust the claim. We show you the status either way — including when the status is "nothing yet". Every QuBottle capability below carries one of four labels: Independently validated when third-party testing is complete and published, Prototype-demonstrated when it runs on our own development hardware, Planned when it is in the design but not yet built or measured, and Test not yet commissioned for testing we intend to run but have not ordered. A sensor is not the same thing as accuracy. A UV‑C LED is not the same thing as a measured reduction.
Where we actually stand today, stated plainly. No independent laboratory testing of treatment performance or measurement accuracy has been performed, and none has been commissioned. An earlier version of this page said validation was "being commissioned"; that was not accurate and has been corrected. No efficacy figure, log reduction or removal percentage is claimed anywhere on this site, and none will be published until a third-party report is on file.
Evidence status
Fluid-intake measurement
Test not yet commissionedLoad-cell weight sensing runs on our bench hardware today and streams live readings; calibration is in progress. Controlled testing of measurement accuracy against a calibrated reference scale has not been commissioned, and no accuracy figure is published.
What we're testing →Four-stage treatment performance
Test not yet commissionedIndependent, organism-specific microbial testing of the treatment architecture, and filtration-stage performance testing, have not been performed or commissioned. Optical dose in the flow cell is unmeasured.
What we're testing →Realistic drinking patterns
Research plannedWhether measurements hold up across real drinking behavior, not just controlled totals.
Why this matters →Motion
Research plannedWhether movement introduces measurement error. Bottles are rarely used sitting still.
Why this matters →Temperature
Research plannedInternal and external temperature effects on measurement.
Why this matters →Beverage variation
Research plannedWater isn't the only thing people drink. Density and type may matter.
Why this matters →Battery life
PlannedInternal power models disagree with each other, so no defensible public figure exists. Nothing is published until bench validation returns a measured number.
Behavioral outcomes
Research plannedEngagement and retention research in design with university partners.
Why this matters →When a card turns Independently validated, the result is published with context — what was tested, the reference method, sample size, conditions, error definition, limitations, and date. Never just a percentage.
Measure what you actually drink
A load cell in the base measures changes in bottle mass, so intake is estimated automatically — no manual logging. One distinction we hold ourselves to: a bottle can measure fluid that leaves the bottle. That is not automatically the same as fluid you swallowed, and neither is the same as your body's hydration status.[1] QuBottle estimates intake behavior; it does not claim to measure physiological hydration. Read the full distinction →
Treat the water you actually drink
The intended architecture. QuBottle's planned treatment straw is detachable and carries four stages in order: a sediment mesh, an activated carbon stage, a NanoFiber stage, and then an enclosed UV‑C flow cell. The UV‑C emitter itself sits dry in the crown and lights that flow cell through a fused-silica window, so no electronics sit in the wetted path. UV‑C performance is not about having a light — it depends on delivered dose, exposure time, water clarity and optical geometry.[4] How UV-C bottles actually work →
What we have demonstrated about it: nothing yet. The four stages are a design, not a result. We have not measured optical dose in the flow cell, we have not run organism-specific testing, and we have not run filtration-stage performance testing. None of that work has been commissioned. We name the stages so you know what is being built, not to imply any of them has been shown to remove or inactivate anything.
UV-C is not a filter, and a filter is not disinfection. UV‑C does not remove sediment, dissolved metals, salts, PFAS, microplastics or other chemical contaminants, and filtration does not inactivate microorganisms. That is precisely why the planned straw combines both. To be exact about the status: filtration is in the intended product and has always been, but QuBottle makes no contaminant-removal claim — no PFAS, lead, chlorine, microplastic or heavy-metal removal claim, and no percentage — because no such test has been run. If that changes, the supporting test data is published here first. UV-C vs filtration, explained →
Do not read "antimicrobial" into the NanoFiber stage. Internal engineering documents have at times labelled that stage with an antimicrobial material name. That is a material-selection label, not a performance claim, and we do not publish it: asserting that a surface kills or controls microbes is a pesticidal claim requiring a registration we do not hold. QuBottle claims no antimicrobial, sanitising, sterilising or self-cleaning performance of any kind.
Test instead of assuming
Peer-reviewed research has already established parts of this category: a connected bottle has measured 24-hour intake to within about 3% of manual recording in published validation work.[1] We treat that literature as the bar, not a threat. The open questions in the field — accuracy beyond controlled daily totals,[2] performance in free-living conditions, and why users disengage from hydration hardware[3] — are exactly what our program is designed to test. What accuracy studies actually show →
Why these tests matter
Motion
Why test it? A bottle is rarely used sitting perfectly still. What we're evaluating: whether movement changes intake measurements. Status: planned.
Beyond daily totals
Why test it? A daily total can look accurate while the measurements inside it are not.[2] What we're evaluating: measurement agreement across realistic drinking patterns against a calibrated reference. Status: protocol in design.
Engagement over time
Why test it? Published trials suggest hydration hardware often loses its users — and a device that stops being used can't help anyone.[3] Understanding the difference between "didn't drink" and "didn't use the bottle" is one of the least-studied questions in the category. Status: research program in design.
FAQ
Does a smart water bottle actually measure hydration? No — no smart bottle does. Bottles estimate fluid removed from the bottle. QuBottle measures intake behavior and does not claim to measure physiological hydration status.
Do UV-C water bottles work? UV‑C at germicidal wavelengths can inactivate many bacteria and viruses, but performance depends on dose, time, water clarity, and geometry. That's why we're testing our specific design rather than quoting generic figures.
Is QuBottle scientifically validated? Not yet — and we won't say it is until it is. Results will be published here, with methods and limitations, when testing is complete.
Built to prove it — and honest until it's proven.
