TDS Testing

Excerpt:

We were intrigued by ZeroWater’s claim of "0 Total Dissolved Solids," and the 32-cup dispenser certainly delivers. The five-stage filter system brilliantly tackles metals, chlorine, lead, chromium, and even PFOA/PFOS, with IAPMO certification adding to our confidence. Testing it side-by-side with a standard TDS pitcher, we noticed a clear difference—our water was purer, tasting crisp and clean. The large capacity is a plus for us, especially when hosting gatherings, though we did wish the replacement filters were slightly less expensive. Still, the transparency of its 0 TDS measurement is a standout feature, making each glass refreshing. While the glass could be more shatterproof, the performance alone makes it a compelling choice for anyone serious about water quality at home.
