h2oMatch helps you understand mineral waters using official label data such as sodium, calcium, magnesium, bicarbonate and fixed residue. You can search for a specific water, compare waters side by side, use the Water Calculator to filter by mineral preferences, and get personalized matches based on your lifestyle and taste preferences. It is designed to make water labels easier to understand and mineral water choices more transparent. Not all water is equal! Find the ones that fit you best!

I built h2oMatch after realizing how hard it is to compare mineral waters in a meaningful way and understand which water fits you better. Every bottle has numbers on the label - sodium, calcium, magnesium, bicarbonate, fixed residue - but those numbers are difficult to interpret. h2oMatch turns official label data into simple comparison, filtering and personalized matching tools. It is not medical advice and it does not rank waters as universally “best.” The idea is simpler: help people understand what’s in the bottle and choose more consciously the waters that fit better their preferences or life style. I’d love your feedback on the product and which countries or brands you’d like us to add next.
