A whole-home (point-of-entry) water filter treats all the water entering your house before it reaches any tap, shower, or appliance. For North Alabama city water users, the primary targets are chloramine removal and sediment — two things a water softener alone doesn't address.
Why Standard Filters Don't Work for Huntsville Water
Huntsville Utilities switched to chloramine in 2021. Most whole-home filters on the market use standard activated carbon, which removes free chlorine efficiently but struggles with chloramine — requiring much longer contact time than a typical whole-home system provides. You need catalytic carbon media specifically.
Our Top Picks
Aquasana Rhino EQ-1000
The Rhino uses a combination of copper-zinc KDF and catalytic carbon — the only media combination that reliably reduces chloramine in a whole-home flow rate. 1,000,000-gallon capacity (approximately 10 years for most households). NSF/ANSI 42 & 61 certified. Our #1 pick for Huntsville homes specifically because of the chloramine issue.
iSpring WGB32B 3-Stage Whole Home Filter
A solid budget option using a CTO (chlorine, taste, odor) carbon block. Note: this uses standard activated carbon — it will reduce chloramine to some extent but not as effectively as the Aquasana Rhino. Better suited for Morgan County (Decatur) where chlorine, not chloramine, is used for disinfection.

A whole-home filter and a water softener serve different purposes and are best used together. Install the filter after the softener in the flow sequence — softened water passes through the carbon media more efficiently, and the filter doesn't have to work against heavy mineral loading.
