A 2024 PNAS study found the average liter of bottled water carries roughly 240,000 plastic fragments, most of them nanoplastics small enough to enter cells. This guide ranks what to buy and what to skip, comparing source disclosure, packaging, microplastics, and cost. You'll see why glass-bottled spring water beats cheap single-use plastic, and where a home ionizer fits the picture.

Electrolyzed water is regular water run through an electric current that splits it into two streams, one alkaline for drinking and one acidic for cleaning. This guide explains how it's made, the difference between electrolyzed reduced water and electrolyzed oxidizing water, and why the dissolved molecular hydrogen in the alkaline stream has drawn over 1,000 studies. You'll learn what the research supports and what's still hype.

Most US tap water meets legal safety standards, but the EPA regulates fewer than 90 contaminants while the USGS detected PFAS in roughly 45% of American tap water samples in 2023. This guide compares tap water, filtered water, and ionized water on contaminant removal, pH, dissolved hydrogen, and cost so you can decide what belongs in your glass. If daily health is the goal, ionized water is the only option that combines advanced filtration with dissolved molecular hydrogen above the therapeutic threshold.
