The HydroTech 41400008 is a genuine OEM reverse osmosis (RO) membrane designed specifically for HydroTech RO systems, including the HydroTech 103 Series, 203 Series, and other compatible residential RO units. This TFC (Thin Film Composite) membrane produces up to 35 gallons per day (GPD) of purified water and is engineered to deliver superior contaminant rejection for HydroTech's point-of-use drinking water systems.

The HydroTech 41400008 RO membrane features an ultra-fine filtration rating of approximately 0.0001 microns, making it one of the most effective filtration stages in your HydroTech system. It delivers up to 96-98% rejection of total dissolved solids (TDS), including lead, arsenic, fluoride, nitrates, sodium, chromium, cysts, and other dissolved inorganic contaminants. This semi-permeable membrane ensures your HydroTech system produces crisp, purified drinking water.

The HydroTech 41400008 reverse osmosis membrane should be replaced every 24 to 36 months under normal household usage conditions. Replacement intervals may vary based on your feed water quality, TDS levels, daily water consumption, and whether the pre-filters (sediment and carbon) in your HydroTech system are replaced on schedule every 6-12 months. Regular pre-filter replacement is critical to protecting the 41400008 membrane and extending its service life.

The HydroTech 41400008 is manufactured to meet industry performance standards for reverse osmosis membranes and is tested against NSF/ANSI 58 criteria for TDS reduction and contaminant rejection when installed in a complete HydroTech RO system. As a genuine HydroTech OEM replacement, it maintains the certified performance specifications of your original HydroTech reverse osmosis drinking water system.

To install the HydroTech 41400008, shut off the feed water supply and drain the RO storage tank. Unscrew the membrane housing cap on your HydroTech system, remove the old membrane, and insert the new 41400008 with the double O-ring end going in first. Reassemble the housing, turn the water supply back on, and allow the tank to fill completely. Drain the first full tank (and ideally a second) before using the water—this flushing process removes manufacturing preservatives and conditions the membrane for optimal performance.
