The Hydrotech 33001068 is a Thin Film Composite (TFC) reverse osmosis membrane designed specifically for Hydrotech RO systems. It reduces up to 99% of total dissolved solids (TDS) and filters contaminants down to 0.0001 microns, effectively removing lead, arsenic, fluoride, nitrates, chromium, copper, and other dissolved impurities. This semi-permeable membrane is the core filtration component that delivers purified drinking water in compatible Hydrotech reverse osmosis systems.

The Hydrotech 33001068 TFC membrane has a service life of approximately 24 months (2 years) under normal household use and typical feed water conditions. Replacement intervals may vary based on water quality, TDS levels, and daily usage. For optimal performance, it is essential to replace the pre-filters (sediment and carbon) every 6–12 months to protect the RO membrane from chlorine damage and sediment fouling, which can significantly shorten its lifespan.

The Hydrotech 33001068 membrane is rated for a 35 gallons-per-day (GPD) production capacity at standard operating conditions (77°F and 60 psi). Its filtration rating is 0.0001 microns, making it one of the finest filtration technologies available for residential drinking water. This ultra-fine pore size allows it to reject dissolved solids, heavy metals, and microscopic contaminants that standard carbon or sediment filters cannot capture.

Yes, the 33001068 is a genuine Hydrotech OEM (Original Equipment Manufacturer) replacement membrane, engineered to fit and perform precisely in Hydrotech reverse osmosis systems. Using the authentic Hydrotech membrane ensures proper fitment within the membrane housing, maintains the system's rated rejection percentage, and preserves any applicable manufacturer warranty. Generic alternatives may not deliver the same TDS rejection rates or dimensional accuracy.

For the Hydrotech 33001068 TFC membrane to operate at peak efficiency, feed water should be within a pressure range of 40–100 psi, a temperature range of 40–100°F (ideally 77°F), and a pH range of 3–11. The feed water must be chlorine-free, as chlorine will permanently damage the thin film composite layer. Maximum TDS input should not exceed 2,000 ppm. Always install fresh sediment and carbon pre-filters before replacing the membrane to maximize its service life and rejection performance.
