Benefits of Using the 1812 100 GPD FilmTec

This membrane ensures consistent permeate flow, excellent contaminant removal, and improved water taste. Additionally, it reduces dissolved solids and provides long-lasting reliability. Furthermore, it fits standard 1812 housings, making installation straightforward. As a result, homeowners and small offices can enjoy clean, safe drinking water with minimal maintenance.

Moreover, its advanced thin-film composite technology enhances durability, allowing stable performance even with daily use.

Installation & Maintenance

1. Confirm your RO system supports 1812 membranes.
2. First, install sediment and carbon pre-filters to protect the membrane.
3. Insert the membrane following the proper flow direction.
4. Next, flush the system to remove preservatives.
5. Monitor TDS levels and replace the membrane when performance declines.
