Overview

Upgrade your undersink drinking water setup with the Dow FilmTec TW30-1812-100HR membrane. This 100 GPD thin-film composite (TFC) element is designed to slot into compact reverse osmosis systems, delivering dependable filtration performance for home use. Built on advanced membrane technology and automated fabrication, it strives for consistent results across typical residential installations while fitting standard housings.

Key advantages come from the polyamide TFC construction and a design that emphasizes reliability. The unit is shipped dry, helping preserve shelf life and make handling straightforward before installation. When paired with a suitable pre-filter, it can help manage water quality before filtration, especially in chlorinated municipal supplies.

What makes it stand out

  • High rejection potential paired with a practical 100 GPD capacity for daily home use.
  • Engineered to operate at about 50 psi, which can yield more efficient water production under real-world conditions.
  • Shipped dry for convenient storage and longer shelf life prior to installation.
  • Free chlorine tolerance: < 0.1 ppm, when used with appropriate pretreatment, to help guard the membrane’s performance.
  • NSF/ANSI Standard 58 certified, offering an established quality benchmark for home drinking water components.

Technical snapshot

  • Size: 1.75" x 11.74" (fits standard 2" x 12" pressure vessels).
  • Output: 100 GPD under typical operating conditions.
  • Material: Polyamide Thin-Film Composite (TFC) membrane.
  • Pre-filter note: For chlorinated water, a carbon/sediment pre-filter is recommended to protect the membrane.

Practical use and installation tips

Designed for home drinking water setups, this membrane makes a straightforward upgrade or replacement option for undersink RO systems. Expect simple integration with common fittings and vessels, and plan for periodic checks of pre-filters and system pressure to maintain steady performance. Actual results can vary with water quality and overall system configuration, but the TW30-1812-100HR is built to support reliable, everyday filtration in many residential contexts.
