Filmtec (TW30-1812) Thin Film Composite Replacement Residential Reverse Osmosis Membrane

Filmtec

TW30-1812 Thin Film Composite RO Membrane

Industry-standard residential reverse osmosis membrane with proven thin film composite technology
NSF/ANSI 58 Listed 1.8" × 12" Standard Size 50 GPD at 50 PSI 2-5 Year Service Life
The TW30-1812 is the workhorse membrane in residential reverse osmosis systems, using Dow Filmtec's thin film composite technology to reject up to 99% of total dissolved solids. Rated at 50 psi rather than the typical 60 psi, this membrane produces approximately 20% more permeate water than competitive elements while maintaining excellent rejection rates across a wide range of contaminants including lead, arsenic, fluoride, nitrates, and hardness minerals.
SPECIFICATIONS

TW30-1812 Technical Data

COMPATIBILITY

Fits Most Standard Residential RO Systems

The TW30-1812 fits conventional residential reverse osmosis systems with 1812-size membrane housings, which represents the vast majority of under-sink and countertop units. This includes systems from APEC, iSpring, Watts, Express Water, and most other major brands using standard 1.8" × 12" membrane housings. Direct replacement for Filmtec TW30-1812-50, TW30-1812-100, and functionally equivalent to BW60-1812-75 in residential applications. Verify your existing membrane size before ordering, but if your system uses a white cylindrical membrane approximately 12 inches long, this is almost certainly the correct replacement.
