⭐ Key Features

•SEVEN PIECES, A FULL YEAR OF SERVICE - Two sediment cartridges, two carbon block pre-filters, two inline carbon post filters and one 36 GPD TFC membrane. That is two changes of the pre and post filters at the usual six month interval, plus the membrane that normally runs two years, in one box.

•WHAT EACH STAGE DOES - Sediment first, catching sand, silt and rust so the stages behind it are not doing that work. Carbon block second, reducing the chlorine taste and odor. The membrane third, which is the stage that does the actual reverse osmosis. Inline carbon last, polishing the water on its way to the tap after it has sat in the storage tank.

•FITS AC-30 AND RELATED SYSTEMS - A replacement set for AC-30, and the same cartridges suit AC-15, H83, H83S and LC50 systems. This is a compatible replacement made by CFS, not an original manufacturer part, and model numbers are used for reference only to show what it fits.

•CHANGE THE PRE-FILTERS ON TIME AND THE MEMBRANE LASTS - The sediment and carbon stages exist to protect the membrane, which is the expensive part. Chlorine damages TFC membrane material, so a spent carbon block is not just a taste problem; it shortens the life of the stage behind it. Every six months on the pre-filters is the interval that matters.

•36 GPD MEMBRANE - Gallons per day is the membrane's production rate under ideal pressure and temperature, not what you will get at the tap; real output is lower and the storage tank covers the gap. Low incoming pressure is the usual reason a system seems slow. For any specific contaminant you are concerned about, look for a system certified to the NSF/ANSI standard that names it.

📋 Product Description

CFS seven piece replacement filter set for AC-30 reverse osmosis systems: two sediment cartridges, two carbon block pre-filters, two inline carbon post filters and one TFC membrane rated at 36 gallons per day. That is a full year of service in one box, since the pre and post filters change every six months and the membrane normally runs about two years. A reverse osmosis system is four jobs in sequence, and it helps to know which cartridge is doing what. Sediment goes first and catches sand, silt and rust, so the stages behind it are not wasting their capacity on grit. Carbon block goes second and reduces chlorine taste and odor. The membrane is third and does the actual reverse osmosis, which is the stage people mean when they talk about RO. The inline carbon filter is last, polishing the water on its way to the tap after it has been sitting in the storage tank. Changing the pre-filters on time is the single thing that decides how long your membrane lasts. Chlorine damages the thin film composite material a TFC membrane is made from, so a spent carbon block is not only a taste problem, it is shortening the life of the most expensive part of the system. Six months is the interval that matters; the membrane is far more forgiving about its own schedule than it is about yours. On the 36 GPD rating: gallons per day describes what the membrane can produce under ideal pressure and temperature, not what comes out of your tap. Real output is lower, and the storage tank is what covers the difference between production rate and how fast you fill a glass. If a system seems slow, low incoming pressure is the usual reason rather than a failed membrane. This set fits AC-30 systems, and the same cartridges suit AC-15, H83, H83S and LC50. This is a compatible replacement made by CFS, not an original manufacturer part, and model numbers are used for reference only to show what it fits.
