Schedule That Keeps Your ERO-175 at Peak Performance
With AutoShip, replacements go on autopilot. Pick a schedule, and your EcoWater ERO 175 never runs on spent components. Fresh filters show up at your door before the old ones are spent.
Pre-filter and post-filter every 6 to 12 months.
RO membrane every 18 to 36 months, depending on source water quality.
Bottled Water Quality From Your Own Faucet
Fresh filters in the ERO-175 mean pure water for drinking and cooking that matches what you’d get from a bottle, without the ongoing expense or the plastic. The three-stage process handles sediment, chlorine taste, dissolved solids, lead, nitrates, cysts, and radium.
For a compact system that fits under the kitchen sink, the EcoWater ERO 175 punches well above its weight. Maintaining it with compatible filters keeps the cost per gallon far below bottled water. That’s a better deal every month you own it.
Frequently Asked Questions
-
Each stage of the ERO 175 reverse osmosis system depends on the one before it. When the pre-filter reaches capacity, sediment and chlorine hit the membrane directly, accelerating wear on the component that costs the most to replace. Over time, the membrane’s rejection rate drops and water flow slows. A filter set costs a fraction of a membrane.
-
Yes, as long as chlorine levels don’t exceed 2.0 ppm and the feed water has zero iron, hydrogen sulfide, and manganese. The ERO-175 is rated for both municipal and well water supplies within those parameters.
-
No. Our compatible filter set includes a dedicated pre-filter (CM108) and a dedicated post-filter (CM109). Each is designed for its specific position in the system, so make sure you install them in the correct slots.
-
Sticking to the recommended schedule of replacing the membrane every 18–36 months is the most reliable way to keep your system performing consistently.
