Echo RO Tankless Reverse Osmosis Water Filter

Traditional reverse osmosis systems require a bulky storage tank that wastes energy maintaining pressure around the clock. The Echo RO eliminates the tank entirely — water is filtered on demand at 1.2 liters per minute through a continuous supply membrane, so you never wait for a tank to refill. The integrated manifold is leak-free and low maintenance, and tool-free quick-change filters make replacements effortless and mess-free. An intuitive touchscreen display provides real-time feedback on filter life and total dissolved solids (TDS) at a glance.

4-stage filtration

• Stage 1 — Spun PP Filter: removes large-particle sediment, rust, and impurities. Lifespan 3–6 months.
• Stage 2 — Carbon Block Filter (CTO): removes organic particles, unwanted smells, chlorine, and discoloration. Lifespan 3–6 months.
• Stage 3 — Reverse Osmosis Membrane: reduces bacteria, viruses, and heavy metal contaminants. Lifespan 12–24 months.
• Stage 4 — Post Activated Carbon Filter (T-33): reduces bacteria and enhances final water taste. Lifespan 3–6 months.
