ZeroWater 52-Cup
Score: 86/100
Brita UltraMax White
Score: 74/100Rankings
The ZeroWater 52 Cup Ready-Read is a large-capacity dispenser featuring 5-stage ion exchange that removes 99.6-99.7% of dissolved solids. It stands out with an integrated TDS meter and includes two replacement filters to enhance initial usability. While highly effective, filter lifespan is dependent on incoming water quality, requiring more frequent changes in areas with poor tap water.
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.
