Benefits

This lateral RO membrane provides reliable water output with excellent dissolved solid removal. Moreover, its lateral-flow design supports versatile plumbing layouts while ensuring long-lasting performance. The membrane is easy to install, maintain, and replace, so households and small commercial setups benefit greatly.

Installation & Maintenance

1. Confirm 1812 housing compatibility.
2. First, pre-filter water with sediment and carbon filters to protect the membrane.
3. Install following the correct lateral flow direction and ensure O-rings are seated.
4. Then, flush the system after installation to remove preservatives.
5. Monitor TDS and water flow; replace if performance drops.

Applications

• Home under-sink RO systems
• Small commercial RO water bars
