Mineral Water Guide
How the h2oMatch Score Works
A personal compatibility indicator - not a quality ranking.
The h2oMatch Score shows how well a mineral water matches your personal profile. The closer the mineral profile is to your preferences, the higher the score.
It is calculated by comparing your preferences with the mineral composition of each water.
What the Score Represents
The h2oMatch Score shows how compatible a water is with your preferences. It does not represent an absolute evaluation of quality.
A lower score does not mean a water is "worse" - it may simply be less aligned with what you are looking for.
What the Score Uses
The score is calculated using:
- Mineral values from official bottle labels
- Your profile answers
- Weighted comparisons between key parameters, reflecting their importance and how much they vary across different waters
The key mineral parameters evaluated include:
These elements are combined to define your personal reference point for comparison.
How the h2oMatch Score Is Designed
The h2oMatch Score is built around a simple idea: your answers define an "ideal" mineral profile.
Based on your preferences, the system estimates what a well-matched water would look like in terms of its mineral composition.
Each water is then compared to this ideal. The closer its composition is to your profile, the higher the score.
To make this comparison meaningful, the model does not treat all parameters equally. Each mineral is weighted based on:
- How relevant it is for hydration and normal body functions
- How much it varies across different waters
Broader indicators like total mineralization are included in a balanced way to reflect the overall character of a water.
In simple terms: the score defines what "ideal" looks like for you - and measures how close each water comes to it.
Two Profile Levels
The scoring system adapts to how much information you provide:
Standard Profile
Uses your 5 answers and returns qualitative labels: High, Average, or Low compatibility.
Premium Profile
Uses all 12 answers to generate a refined profile and shows a more precise numeric score for each water.
Both modes use the same underlying engine - the Premium profile simply provides higher precision in both input and output.
Why Scores Can Differ Between Users
Two people can get very different scores for the same water. This happens because the score is based on individual preferences and profiles, not a universal ranking.
Different preferences lead to different scores for the same water
A high score means the water fits your profile - not that it is objectively better
The goal is to find what fits you, not to rank waters universally
Transparency
All mineral values used by the scoring system come from publicly available label data. No proprietary medical data or undisclosed parameters are used in the calculation.
The h2oMatch Score reflects compatibility with your preferences. It does not represent an absolute evaluation of a water's quality and does not constitute medical advice.
Key Takeaway
The h2oMatch Score is personal - it measures how well a water fits your specific preferences, not how good it is in absolute terms. Two users will get different scores for the same water - and that's exactly the point: it is about finding what fits you.
