How to install your ZeroWater filterUpdated 2 months ago

How to seat the filter correctly

1. Hold the filter with the flat base facing down and the threaded neck pointing into the reservoir.
2. Insert the filter into the hole in the bottom of the upper reservoir.
3. Turn clockwise until you feel resistance, then give it one firm additional quarter-turn. The filter should feel snug — not wobbly.
4. Do not overtighten. If you're using significant force, stop — the filter may be cross-threaded. Remove it and start again.

How to check the filter is seated correctly

After filling the reservoir with water, check underneath the upper reservoir before placing it on the pitcher. There should be no dripping from around the filter neck. If you see drips, the filter is not fully tightened.

The water isn't flowing through — what's wrong?

A very slow flow on a brand-new filter is normal for the first fill. For a full guide on diagnosing and fixing slow flow, see My water is filtering very slowly — what should I do?
