What is purely fact? If instead of "Pure drinking from the nature", vendors market their products with one of these:

- Pure hydration, straight from the heart of pristine nature

- Crisp, untouched refreshment in every drop

- Silky refreshment straight from the source

- Clean, effortless hydration as nature intended

- Unfiltered clarity from mountain to bottle

- Naturally balanced, untouched by process

- Purity preserved from subterranean springs

Can you say they aren't purely fact? How do you prove it? Can you deny that marketing?

(I of course asked LLM for those alternatives)
