Review on KX 06-250-10-GREEN Pb1 Carbon Block Filters - Chlorine Taste, Odor & VOC Reduction, Lead & Cyst Removal - KX MatriKX Powered by GREENBLOCK - Replaces 06-250-125-975 by Lisa Starcher

I have used these filter blocks before and they work very well. A well-functioning and well-maintained reverse osmosis system is absolutely essential to the maintenance of your reverse osmosis membranes. That will help. Get as low a TDS as possible before injecting membranes and they will last for years (3-5 years). With this and other micron media I get 0-2 TDS. No hard water or limescale deposits in coffee pots and kettles. No chemicals to drink.
