The ILMA-6.14 is a mineral addition cartridge for the OP70, OPS70, OP70CR series. The OP70 water treatment system uses reverse osmosis (RO) to remove TDS and then dissolves a balance of minerals, using the ILMA-6.14, to produce an "optimized" water solution. This replacement cartridge is exactly the same as the ILMA-6.14 that first came with your OP70 filtration system.
