⭐ Key Features

•Full service kit: sediment, two carbon blocks, quick connect inline post-filter, 50 GPD membrane, wrench, 2 O-rings: 1/4" line Quick-Connect fittings are built in to the filter so no additional fittings are required. Just push the line in and the quick-connect fitting grabs and seals the line. The fastest and easiest way to change your filters.

•EIGHT PIECES, ONE SERVICE - Everything a five-stage system takes in one box: one sediment prefilter, two carbon block cartridges, one threaded inline post-filter, one 50 GPD reverse osmosis membrane, a housing wrench and two O-rings. The membrane is included rather than sold separately, and so is the wrench - the two things people discover they are missing halfway through a filter change.

•WHAT EACH STAGE DOES - The sediment prefilter reduces sand, silt and rust so nothing downstream is doing particulate work. The two carbon blocks reduce chlorine taste and odor, and in doing so protect the membrane, because chlorine shortens membrane life more than anything else in normal household water. The membrane reduces dissolved solids. The inline carbon is the last stage before the faucet.

•1/4" line Quick-Connect fittings are built in to the filter so no additional fittings are required. Just push the line in and the quick-connect fitting grabs and seals the line. The fastest and easiest way to change your filters.

•MATCH THE SCHEDULE TO THE STAGE - The pieces do not share a clock. Most households change the sediment and carbon stages every six to twelve months and the membrane every two to three years, so keep the membrane sealed until you fit it. Replace the prefilters on schedule even if the water still tastes fine, because a spent carbon stage stops protecting the membrane and the membrane is the expensive part.

📋 Product Description

A complete eight-piece service kit for a five-stage under-sink reverse osmosis system. What is in the box: one sediment prefilter, two carbon block cartridges, one quick connect inline post-filter, one 50 GPD thin-film composite reverse osmosis membrane, one housing wrench and two O-rings. Two of those are the pieces most replacement sets leave out. The membrane is usually sold separately, and the wrench is usually assumed — which is a problem the first time someone tries to open a housing that has been under pressure for a year. How the stages work together. The sediment prefilter reduces sand, silt and rust so nothing downstream is doing particulate work it was not built for. The two carbon blocks reduce chlorine taste and odor, and in doing so protect the membrane, because chlorine shortens membrane life more than anything else in normal household water. The membrane is the stage that reduces dissolved solids. The inline carbon cartridge is the last stage before the faucet and polishes the taste of the finished water. The inline post-filter uses 1/4 inch quick connect push-fit fittings at both ends, for 1/4 inch OD copper or poly tubing. Cut the tube square, push it fully into the collet until it seats, then tug gently to confirm it has gripped; to release, push the collet in toward the body and draw the tube out. If your system uses a threaded inline cartridge that screws on rather than pushing in, this kit will not match at that stage — check the small cartridge nearest the faucet before ordering. The pieces do not share a service schedule. Most households change the sediment and carbon stages every six to twelve months depending on use and water quality, while a membrane typically runs two to three years. Keep the membrane sealed in its bag until the day you fit it.
