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.
Pros and cons
- Large 33-cup capacity means fewer refills for households
- Built-in TDS meter to track filtration
- Filter replacement cost adds up for heavy-use households
- Cartridges can need changing sooner under heavy demand
- Takes up more space than the smaller pitcher
