The Echo Reverse Osmosis Filter will provide you with clean fresh tasting water. But in order to keep the system running at optimum levels you must replace the filters at regular intervals.

| RO Membrane (LABELED 3, or RO) | Removes bacteria, heavy metals, dissolved matter, and salinity. | 12 - 24 months |
| Post Activated Carbon Filter (LABELED 4, or TT3) | Removes residual chlorine and odor. It also improves the taste of purified water. | 3 - 6 months |
