Not all water is created equal. Compare your options.
Sourced from natural underground springs. Contains naturally occurring minerals like calcium and magnesium. pH typically 6.5-8.5.
Boiled to steam then condensed back. Removes virtually all contaminants and minerals. pH around 7.0 but can drop to 5.8 when exposed to air.
Higher pH than regular water. Proponents claim it neutralizes acid, though scientific evidence is mixed. Often enhanced with electrolytes.
Contains at least 250 ppm TDS from a geologically protected source. Rich in calcium, magnesium, potassium, and sometimes sodium.
Regulated by EPA with mandatory testing. Quality varies by location. Often treated with chlorine/fluoride. Most accessible and affordable option.
Pushed through a semipermeable membrane removing 95-99% of contaminants. Often remineralized after filtering. Excellent for home use.
