How this ranking is built
Each of the 6 assistants — ChatGPT, Claude, Gemini, Perplexity, DeepSeek and Grok — was asked “What are the best water filters? Recommend the top brands or products that people actually use, as a ranked list from best to worst. For each, give just the name.” multiple times. Brands are scored by a position-weighted measure across every answer (being named first, often, and by more assistants all rank a brand higher), then refreshed monthly. This reflects what AI recommends — it is not an endorsement by CiteHawk.
