Overview
At 33 cups, model ZEROD33 is the largest dispenser in Culligan's ZeroWater Technology lineup, built for households or offices that go through more water than a standard pitcher holds.
This is the volume option in Culligan's lineup: sized for bigger households, offices, or anyone tired of refilling a smaller pitcher multiple times a day. It runs the same 5-stage filter and TDS meter as the smaller dispensers, so the filtration chemistry is identical and only the capacity changes.
- 33-cup capacity, the largest in Culligan's ZeroWater Technology lineup
- Same 5-stage filtration and TDS meter as the smaller models
- Sized for larger households or shared office kitchens
- Requires new Culligan with ZeroWater Technology cartridges
Who it's for
Suited to a larger household, a shared office kitchen, or anyone who refills a smaller pitcher too often. Overkill for one or two people, where the 12-cup pitcher fits the fridge better.
What buyers say
From Amazon customer reviews.
Buyers describe the water as tasting notably purer than what they got from Brita, PUR, or plain tap water, with several mentioning that ice made from this water comes out clear rather than cloudy. As with the smaller Culligan models, the tradeoff is filter life: heavier households report replacing cartridges sooner than expected, and the ongoing cost of new filters is the most common gripe even among reviewers who otherwise rate the taste highly.
Strengths and trade-offs
Drawn from this product's published specifications.
- Large 33-cup capacity means fewer refills for households
- Water and ice reviewers describe as clearer
- Built-in TDS meter to track filtration
- Filter replacement cost adds up for heavy-use households
