Score: 80/100
Brita UltraMax White
Score: 74/100Rankings

The Culligan with ZeroWater Technology 32 Cup Dispenser is a gravity-fed water filtration system that removes 99.9% of total dissolved solids using a 5-stage filtration process. It includes a built-in TDS meter for real-time water quality monitoring and offers purification comparable to reverse osmosis without requiring electricity. It is best suited for families requiring large quantities of filtered water without frequent refilling and households with high TDS 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.
