• High rejection at start-up and after stabilization
• Up to 20% higher flow rates than competitive elements operated at the same pressure
• Stable, reliable performance even when treating high hardness waters
• NSF International safety certification and ability for NSF data transfer to reduce certification costs
• Dry shipping for convenient handling and long shelf-life

FilmTec™ Residential Reverse Osmosis (RO) Elements are some of the most reliableand consistent elements manufactured in the industry. Advanced membrane technology and precision manufacturing result in elements produced to tight, predefined specifications with consistent RO element performance. DuPont’s focus on manufacturing excellence is an essential measure to ensure OEM and brand owner customers develop and maintain their reputation for building world class, reliable water purifiers that produce water consumers can trust.

FilmTec™ TW30-1812-50HR Residential RO Elements offer quick stabilization at high rejection and flow performance, and long effective lifetimes. Element performance is achieved by coupling FilmTec™ patented membrane flat sheet technology with efficient element designs that are less prone to flux loss due to scaling. Systems are enabled to produce reliable, high quality water with minimal system maintenance costs.
