When replacing your RO membrane, consider these key factors:
1. **Capacity**: Ensure the membrane matches your system's daily water output requirements, such as 50 GPD for domestic or higher for industrial use.
2. **Material**: Opt for durable materials like polyamide for efficiency and longevity.
3. **Compatibility**: Verify the membrane is compatible with your RO housing model and system specifications.
4. **Contaminant Removal**: Check the membrane's rejection rate for impurities like TDS, heavy metals, and microbes.
5. **Brand and Quality**: Choose reputable brands for reliable performance and warranty support.
Proper selection ensures optimal purification and system durability.
