The best alkaline water brands
Updated · Scores from third-party lab reports · How we score
The best alkaline water is Acqua Filette Natural Glass Bottle (95/100), followed by Acqua Filette Gently Sparkling Glass Bottle (95/100), Ophora Water Hyper-Oxygenated Half Gallon Glass Bottle (91/100) and Galvanina Still Mineral Water Glass Bottle (91/100). Every one of these 54 waters has a reported pH of 8 or higher.
Naturally alkaline waters get their pH from dissolved minerals. Many "ionized" alkaline brands are purified water with electrolytes added. A high pH alone does not make a water healthier, so we rank these by overall purity, not by pH.

Frequently asked questions
What is the best alkaline water brand?
Acqua Filette Natural Glass Bottle (95/100) is the highest-scoring alkaline water in our data.
Is alkaline water healthier?
There is limited evidence that alkaline water improves health for most people. Your stomach acid neutralizes it quickly. Purity, source and packaging matter more than pH.
How are these waters scored?
Every product gets a 0–100 purity score built from a lab report being on file, contaminants detected versus legal limits and health guidelines, the water source, mineral preservation, packaging material, cap material and PFAS testing. Products without a third-party lab report cannot score high, no matter how good the marketing is.
