ULTRA-pure water 2 1/2 Liters

Ultra-Pure Water - When water needs to be absolutely pure.
Quality suitable for food-grade applications.

Guaranteed purity 0 microSiemens (uS). For your reference, distilled water typically measures at 2-3 uS, while double-distilled water is at 1.9 uS.

The water undergoes multiple stages of purification, beginning with softening, particle filtration, and an adsorption filter with activated carbon. This is followed by reverse osmosis and a final total purification stage that removes both positive and negative substances.

There is hardly any water purer than this, 0 microSiemens (uS). Please note, we're talking about microSiemens, not milliSiemens. Exceptionally pure.
