Isopure Water (ISO-RO4) 4 Stage Reverse Osmosis System 50 GPD
The ISO-RO4 is a compact 4-stage reverse osmosis system that removes 90-99% of total dissolved solids and 99% of organics from well or municipal water supplies. At 50 gallons per day, it provides clean drinking water for households without the recurring cost of bottled water.

ISO-RO4 System Details
| Model Number | ISO-RO4 |
| Production Rate | 50 GPD |
| Dimensions (RO Unit) | 12"L × 6"D × 18"H |
| Storage Tank | 4 gallon (3.2 gallon usable), 11" × 14" |
| Inlet Pressure Required | 40-100 psi (2.8 bar minimum) |
| Water Temperature Range | 40-85°F (4.5-30°C) |
| Max TDS | 2,000 ppm |
| Included Faucet | Chrome non-air gap |
FILTRATION STAGES
Four-Stage Purification Process
SEDIMENT
Removes sand, rust, silt, and particles down to 5 microns
CARBON
Carbon block filter eliminates chlorine, chloramines, and organic compounds
MEMBRANE
Semi-permeable RO membrane rejects dissolved solids, bacteria, and viruses
POLISH
Post-carbon filter refines taste and removes residual odors before dispensing
INSTALLATION & USE
Setup Overview
- Mount the RO unit under the sink or in a utility room where it can access a cold water line and drain connection. Ensure at least 40 psi water pressure is available.
- Install the chrome faucet on the sink deck or countertop, then connect tubing from the RO unit to the faucet and from the cold water supply to the system inlet.
- Connect the drain saddle to the sink drain line and position the 4-gallon storage tank nearby with adequate clearance for future filter changes.
- Open the inlet valve slowly, check all connections for leaks, and allow the system to flush and fill the storage tank completely before first use.
- Replace pre-filters annually and the RO membrane every 2-3 years depending on source water quality and usage volume.
COMPATIBILITY
Water Source Requirements
The ISO-RO4 is designed for potable municipal or well water with TDS levels below 2,000 ppm and pH between 4-11. It requires a minimum inlet pressure of 40 psi to function properly. If your home has low water pressure, a booster pump may be necessary. This system is not suitable for brackish or seawater desalination. Standard replacement filters from Isopure Water fit this model, making long-term maintenance straightforward.
🔧 Pro Tip: Flush the system for 30-60 minutes after installing new filters to clear manufacturing residues and fine carbon particles. The first few tanks of water may appear slightly cloudy or have a carbon taste, which is normal and will clear after the initial flush cycle.
