Excerpt from WQA NSF Test Report
According to NSF 42 Chlorine Reduction test , filters have an average Chlorine Reduction Rate of 99.06%
After having been tested to 1500G, the Chlorine Reduction is 98.57%, still much higher than the NSF42 standard which is 50%.
It means after using 1500G, the filter can be continuely used for Chlorine Reduction.
We strongly suggest that you should replace the filter every 6 months.
