Learn the replacement schedule for the DREO RO Water Filter 112 and its replacement filter. Know when to swap each part for clean, safe drinking water.
Quick answer
For the DREO RO Water Filter 112, replace the RO filter every 6–12 months and the replacement filter when the TDS reading rises or the smart indicator alerts you. Regular maintenance keeps your water clean and your system running smoothly.
Why regular replacement matters
The RO Water Filter 112 uses RO filtration to remove up to 99.99% of contaminants, improving taste and ensuring safe drinking water. Over time, the filter media becomes saturated and less effective, so sticking to a replacement schedule is key to maintaining water quality.
The built-in real-time TDS monitoring and smart indicators give you a clear picture of water quality, so you don't have to guess when a change is due. However, relying solely on indicators can be tricky—some issues, like a slow decline in performance, may not trigger an alert immediately.
Signs you need a filter change
Watch for these signs that your RO filter or replacement filter needs attention: a noticeable drop in water flow, a change in taste or odor, or an increase in the TDS reading. The smart indicator light may also turn red or blink to signal it's time.
If you notice any of these signs, don't wait—replace the filter promptly to avoid contaminant buildup and keep your water fresh.
Step-by-step replacement schedule
- Check the TDS reading weekly: Use the real-time TDS monitor to see the total dissolved solids in your water. If the reading rises above the recommended level (usually above 50 ppm), it's time to plan a filter change. A sudden spike in TDS is a clear early warning—don't ignore it.
- Replace the RO filter every 6–12 months: Even if the TDS reading looks fine, replace the RO filter every 6 to 12 months. This prevents gradual buildup and maintains consistent contaminant removal. Set a calendar reminder so you don't forget based on usage.
- Monitor the smart indicator light: Pay attention to the smart indicator on the system. When it changes color or blinks, it's signaling that the filter is nearing the end of its lifespan. Replace the filter within a week of the alert. Don't wait for the light to turn red—act on the first warning.
