How to Remove Chloramine from Tap Water

What is chloramine, and why is it hard to remove?

Chloramine is chlorine combined with ammonia. Water utilities use it because it stays stable longer in the pipes than plain chlorine does. That stability is the problem for filtering: chloramine passes right through the standard carbon in most pitcher and fridge filters.

You often notice it as a faint chemical taste or smell, especially in a hot shower.

What actually removes chloramine?

Catalytic carbon is the answer. It is a specially treated carbon designed to break the chloramine bond, not just trap chlorine. Installed as a whole-house filter, it treats every tap in the house, so your shower, your kitchen, and your laundry all get the same water.

The right size depends on your water and your household, which is what the six questions sort out.
