The Science of Chlorine in Municipal Water

Municipalities use chlorine and chloramines as primary disinfectants to kill bacteria and viruses. While essential for public health, these chemicals often linger by the time water reaches your kitchen sink. If your filtered water still tastes like chlorine, you are likely dealing with one of three common issues: filter saturation, bypass, or the presence of chloramines.

1. The Filter Cartridge is Saturated

Most basic filters use Granular Activated Carbon (GAC). These have a finite capacity for chemical adsorption. Once the carbon pores are filled with contaminants, the filter can no longer trap chlorine molecules. This is known as 'breakthrough.'

• The Fix: Check your filter’s lifespan. If you haven't changed it in 6 months or according to the manufacturer's gallon rating, it's time for a replacement.

2. You Are Dealing with Chloramines, Not Just Chlorine

Many modern water treatment plants have switched from chlorine to chloramines (a combination of chlorine and ammonia). Chloramines are more stable and harder to remove than standard chlorine.

Standard carbon filters (like those found in many pitchers or basic fridge filters) are often ineffective against chloramines. You need a specialized filter, such as those found in Woder’s advanced filtration systems, which utilize catalytic carbon or specialized micro-filtration to break the ammonia-chlorine bond.

3. The Problem of "Channeling"

In low-quality filters, water can create small paths or 'channels' through the filtration media. When this happens, the water flows through the gaps rather than making contact with the carbon. This results in water that exits the tap largely untreated.

Why Woder Filters Are Different

Woder filters aren't just standard carbon blocks. Our proprietary Selective Filtration Technology is designed to remove 99.9% of chlorine and heavy metals while leaving essential minerals intact. Unlike generic filters that allow 'bypass' or have short lifespans, Woder filters are engineered for high-capacity performance.

Key Advantages:

• Extended Lifespan: Many of our filters last up to 10,000 gallons.
• Advanced Media: Designed to tackle both chlorine and the more stubborn chloramines.
• High Flow Rate: Eliminates channeling by ensuring uniform contact with the filtration surface.
