Which replacement filter fits my ZeroWater pitcher?Updated 2 months ago

Two filter sizes

ZeroWater makes two replacement filter sizes, and it's important to order the correct one for your pitcher:

• Original ZeroWater filter — standard filter, fits all original ZeroWater pitchers (most of them have the blue reservoir)
• Culligan with ZeroWater technology filter — fits the new Culligan pitchers with drop in filters.

These filters can not be used interchangeably. 

How to check which filter you need

The easiest way is to look at your existing filter. The model number is printed on the side of the filter itself, the original ZeroWater filters are noted as ZR-017. These are the filters that we have available.

Alternatively, check the bottom of your pitcher — the model number of the pitcher is usually printed there, and the product listing on our website will confirm which filter it uses.

Where to buy replacement filters

Replacement filters are available at zerowaterfilter.com. Multi-packs offer better value if you go through filters frequently due to high local water TDS.

Not sure?

If you're unsure which filter fits your pitcher, please contact our customer service team with your pitcher model number or an image of your pitcher and we'll confirm the right filter for you.
