Brita UltraMax White
Score: 74/100Rankings

The ZeroWater 32-Cup Ready-Read is a high-performance countertop dispenser that utilizes 5-stage ion exchange to remove 99.9% of dissolved solids. Its standout feature is the integrated TDS meter, which allows users to monitor water purity in real-time. While the filtration speed is slow due to its gravity-fed design, it is ideal for users prioritizing water quality over speed.

The Brita UltraMax Large Water Dispenser with BritaPlus Filter offers a massive 27-cup capacity and slim design, making it ideal for high-volume households and offices. It effectively reduces chlorine and heavy metals, though the plastic construction feels less durable than premium alternatives. It is best suited for users who prioritize volume and fridge compatibility over premium build quality.
