This RO Pure replacement water filter kit provides a complete one year supply of filters for your Four Stage RO Pure reverse osmosis system. This kit includes two sediment prefilters (105311), two carbon prefilters (105351) and one carbon postfilter (105341). This is everything you need for a full year of operation. The RO Membrane is sold separately as it does not require annual replacement. The Watts RO-Pure reverse osmosis system consists of a stage 1 five micron sediment filter that traps particulate matter like dirt, rust, and silt that will affect the taste and appearance of your water. Stage 2 is a five micron carbon block filter that reduces chloramines, chlorine as well as other materials that cause bad taste and odors (these are called PRE-filters because they filter in front of the reverse osmosis membrane). Stage 3 is the heart of the reverse osmosis system, the RO Membrane. This 50-Gallon per day semi permeable membrane will effectively reduce TDS (total dissolved solids), Sodium and a wide range of contaminants such as Lead, Arsenic, Perchlorate, Chromium, Copper and Radium. It will also remove over 99.95-Percent cysts such as Giardia and Cryptosporidium.
