Stage 4: 1-micron granular activated carbon post-filter (Hydronix ICF-10); enhances taste and clarity; replaces every 12 months
Production Rate: Up to 100 GPD (378 liters/day) ≈ 15.8 L/hour
Rejection Rate: Minimum 95% – Maximum 99%
Operating Pressure: 40–85 PSI (minimum 40 PSI required; max 150 PSI)
Dimensions: 14" L × 6" W × 16–18" H (varies by post-filter position)
Installation: Under-sink mount; includes saddle valve, drain saddle, tank shut-off valve, and dedicated faucet
Comparison: Outperforms standard 3-stage systems by adding a post-filter for superior taste; comparable to Watts PWRO4 but with Hydronix-certified filters for longer lifespan

Detailed Description

The reo-pure 4-Stage RO System Water Filter operates through a scientifically optimized sequence: first, water passes through a 5-micron sediment pre-filter that traps silt, rust, sand, and dust, protecting downstream components . Next, a carbon block filter removes chlorine, chloramine, VOCs, and unpleasant odors—critical since chlorine can degrade the RO membrane . The core stage involves the reverse osmosis membrane, which squeezes water through microscopic pores (1/10,000 micron), eliminating 99% of dissolved solids, heavy metals, and pathogens including giardia and cryptosporidium . Finally, an activated carbon post-filter polishes the water, enhancing clarity and delivering premium taste .

Build quality features durable polypropylene filter housings, high-tensile tubing, and precision-molded O-rings for leak-free performance. The system mounts neatly under your sink, with a 3–5 gallon storage tank (included) for on-demand dispensing . Real-world applications include daily drinking, cooking, coffee brewing, baby care, and aquarium maintenance. Users report consistently smooth water texture, no aftertaste, and significant reduction in bottled water costs. The reo-pure system is designed for potable water sources only and operates most efficiently with filtered feed water (pH <6.5, hardness <10 GPG) .

Troubleshooting

Common issues and solutions for the reo-pure 4-Stage RO System Water Filter include:

Low or No Water Flow: Cause: Clogged sediment/carbon pre-filter or plugged saddle valve. Solution: Replace filters (every 3–6 months) and unclog/open valve . Ensure feed pressure ≥40 PSI .
Tastes or Odors in Product Water: Cause: Exhausted carbon pre-filter, foreign matter in tank, or reversed drain/product lines. Solution: Replace filters, sanitize system, flush tank, and verify plumbing per flow diagram .
System Shuts Down Unexpectedly: Cause: Low feed pressure (<15 PSI) or high product pressure (>45 PSI). Solution: Check household pressure; install pressure regulator if needed .
Excessive Drain Water: Cause: Fouled RO membrane or incorrect flow restrictor. Solution: Replace membrane (every 3 years) and inspect flow restrictor .

Preventive Measures: Replace filters per schedule; sanitize system annually; replace filter housings every 5 years to prevent leaks . Warranty & Support: Alpha Water Systems Inc. provides 7-day tech support (914-489-3068) and 1-year warranty on components .

Pros & Cons

Pros

Superior Filtration: 4-stage process removes 99% of contaminants including lead, arsenic, and 99.95% of cysts
Enhanced Taste: Post-filter ensures crystal-clear, odor-free water with no plastic aftertaste
Cost-Effective: Saves $1,000+/year versus bottled water; filters last 3–12 months
Easy Installation: Includes all parts (faucet, valves, tubing); under-sink mount keeps kitchen tidy
Reliable Performance: Hydronix-certified filters offer longer lifespan than generic brands

Cons

Water Waste: Produces 1 gallon product for 2–3 gallons drain water (typical for RO systems)
Maintenance Required: Filters must be replaced every 3–6 months; membrane every 3 years
Pressure Sensitivity: Requires ≥40 PSI feed pressure; may need booster pump in low-pressure homes
Initial Cost: Higher than basic pitcher filters (~$300 vs. $30) but far more effective

Value for money is excellent: compared to 3-stage alternatives, the reo-pure’s post-filter delivers noticeably better taste. Alternatives like Watts PWRO4 lack Hydronix filters, making reo-pure more durable long-term .
