Key Takeaways:

• The Challenge: Most DFW cities use Chloramine (Chlorine + Ammonia) to disinfect water, not just chlorine.
• The Failure: Standard "Activated Carbon" (GAC) is great at removing free chlorine but very slow and ineffective at breaking down chloramine.
• The Solution: Catalytic Carbon is chemically enhanced to target chloramine, breaking the chlorine-ammonia bond effectively.
• Why it Matters: If you buy a standard filter in DFW, you'll likely still smell chemicals and have ammonia in your water. You need Catalytic Carbon.

If you are shopping for a whole-home water filter in the Dallas-Fort Worth area, there is one technical specification you absolutely must look for: Catalytic Carbon.

The Chloramine Problem

Most older water filters were designed to remove Free Chlorine, which is easy to filter out. However, utilities like the NTMWD (serving Plano, Frisco, Richardson, etc.) now use Chloramines—a combination of chlorine and ammonia.

Chloramines are much more stable than chlorine. This is good for the city (it stays in the pipes longer) but bad for your filter. Standard Activated Carbon works by adsorption, but it struggles to "grab" the chloramine molecule. It can let a significant amount pass right through into your shower and glass.

The Catalytic Solution

Catalytic Carbon is a specialized media that has been altered to have a highly reactive surface. It acts as a catalyst to chemically break the bond between the chlorine and the ammonia.

1. It breaks the chloramine molecule apart.
2. It captures the chlorine.
3. It treats the remaining byproducts.

Don't Buy the Wrong Tank

Many cheap systems sold online or in big-box stores only use standard GAC (Granular Activated Carbon). In North Texas, these systems are effectively obsolete for whole-home filtration. To truly remove the taste, smell, and skin-drying effects of our city water, a Catalytic Carbon system is the only professional choice.
