Most New Zealand households receive chlorinated water through municipal supplies, with typical chlorine levels ranging from 0.3 to 0.8 mg/L. While this chemical treatment protects us from harmful bacteria and waterborne diseases, many families prefer to remove chlorine from their drinking water for better taste, odour, and potential health benefits.
How Water Filtration Systems Remove Chlorine
The good news is that modern water filtration systems excel at chlorine removal. The most effective method uses activated carbon filtration, which removes chlorine through a process called chemical reduction.
Activated carbon filters are highly effective at removing organic compounds, chlorine, and improving taste and odor, making them the gold standard for chlorine removal in residential systems.
Carbon filters work by providing a massive surface area where chlorine molecules bond with the carbon material, effectively pulling them out of your water.
The process is remarkably efficient. Activated carbon block filters have unique properties that can effectively remove total suspended solids, volatile organic compounds, sediment, heavy metals, chloramines, and other contaminants from drinking water.
Three-Stage Filtration: The Complete Solution
Professional-grade water filtration systems use a systematic approach to deliver the best results. A typical three-stage system includes:
First Stage: Pleated 5 Micron Filter removes larger particles like sand, sediment, and rust that could interfere with chlorine removal in downstream filters.
Second Stage: Carbon 5 Micron Filter specifically tackles chlorine, taste, odour, discolouration, and chemical contaminants. This is where the majority of chlorine removal happens, along with the elimination of chemicals like agricultural runoff that can affect water quality.
Third Stage: Melt Blown 1 Micron Filter provides final polishing, capturing any remaining particles and ensuring your filtered water is crystal clear.
Health Benefits of Removing Chlorine
Why should you care about removing chlorine from your drinking water supplies? The benefits extend beyond just better taste and odour.
Chlorine can react with organic matter in water to form byproducts like trihalomethanes, which some studies suggest may have long-term health implications. By removing chlorine, you're also reducing exposure to these secondary compounds.
Many families notice improved taste in their cooking and beverages after installing filtration systems. Coffee, tea, and other drinks taste noticeably better without chlorine's chemical interference.
NSF-Certified Systems: The Gold Standard
When choosing water filtration systems for chlorine removal, certification matters. NSF (National Safety Foundation) certification ensures that systems do what they claim.
In New Zealand, systems certified to NSF 42 standards have been rigorously tested for chlorine reduction performance.
Quality filtration systems use NSF-certified components that are tested for material safety, ensuring no dangerous chemicals, dyes, or adhesives leach into your water.
These cartridges typically last 9-12 months under normal conditions, though heavily chlorinated water or poor source quality may require more frequent changes.
