⭐ Key Features

•150 GPD thin film composite membrane, standard 1812 element; the stage that reduces dissolved solids

•ONE HUNDRED AND FIFTY GALLONS PER DAY - A single thin film composite reverse osmosis membrane rated at 150 GPD under standard test conditions, in the standard 1812 element size. This is the stage that reduces dissolved solids, and it is the piece most replacement sets leave out. It is a membrane only: no sediment prefilter, no carbon, no inline post-filter.

•MATCH THE MEMBRANE TO THE RESTRICTOR - Every system runs a flow restrictor sized to its membrane, and fitting a different rating without changing it throws off the ratio of filtered water to drain water. Too little drain flow scales the membrane early; too much wastes water and drops your tank pressure. If your system was built around 150 GPD, replacing like for like keeps the restrictor you already have correct.

•CHECK YOUR ELEMENT - This is a standard 1812 element and it drops into 1812 and 2012 membrane housings. It replaces HL22121 and fits Stealth RO150, RO200 and RO300 systems. Measure your existing membrane before ordering if your system is not listed - if it is the same element size, this will fit whatever the system is badged as.

•PROTECT IT AND IT LASTS - Chlorine damages this membrane faster than anything else in normal household water, so the carbon stage ahead of it determines how long it lives. Keep those cartridges on schedule. Leave the membrane sealed in its bag until the day you fit it, and flush the system after fitting before you drink from it.

📋 Product Description

A single thin film composite reverse osmosis membrane rated at 150 GPD, in the standard 1812 element size, for systems that take HL22121. This is the stage that reduces dissolved solids in a reverse osmosis system, and it is the piece most replacement sets leave out and sell separately. It is a membrane only - no sediment prefilter, no carbon cartridges and no inline post-filter. Match the membrane to the flow restrictor. Every system runs a restrictor sized to its membrane, and fitting a different rating without changing it throws off the ratio of filtered water to drain water. Too little drain flow scales the membrane early; too much wastes water and drops tank pressure. If your system was built around 150 GPD, replacing like for like keeps the restrictor you already have correct. Higher GPD is faster, not cleaner. The rating is production rate, not quality - a faster membrane fills the tank quicker but does not reduce more. It is a standard 1812 element and drops into 1812 and 2012 membrane housings. It fits Stealth RO150, RO200 and RO300 systems. If your system is not listed, measure your existing membrane - if it is the same element size, this will fit whatever the system is badged as. Chlorine damages this membrane faster than anything else in normal household water, so the carbon stage ahead of it determines how long it lives. Keep those cartridges on schedule. Leave the membrane sealed in its bag until the day you fit it, and flush the system after fitting before you drink from it.
