Follow these clear steps to replace your DREO RO Water Filter 114, ensuring clean water and long filter life. Includes common mistakes to avoid.

Quick answer

Replacing your DREO RO Water Filter 114 is a straightforward process that takes about 10 minutes. Follow the steps below to remove the old filter, install the new one, and reset the filter life monitor.

Why regular replacement matters

The 7-in-1 reverse osmosis system in the DREO Countertop Water Filter 114 removes contaminants effectively, but the filter media wears out over time. Skipping replacement can lead to reduced water quality and slower flow. The built-in TDS and filter life monitoring helps you know exactly when it's time to change.

What you'll need

You only need the replacement RO filter cartridge (model 114). No tools are required. The self-cleaning function handles most maintenance, but the filter itself needs periodic swapping.

Step-by-step replacement process

Turn off and unplug the unit: Switch off the DREO RO Water Filter 114 and unplug it from the power outlet. This prevents the autofill or self-cleaning cycle from starting while you work. Always unplug before opening the filter compartment to avoid electrical hazard.
Remove the old filter cartridge: Open the filter compartment door. Twist the old filter counterclockwise until it unlocks, then pull it straight out. Discard it properly. If the filter feels stuck, do not force it. Check that you are turning it the correct direction.
Prepare the new filter: Remove the protective caps from the new RO filter 114. Align the tabs on the filter with the slots in the compartment. Push it in and twist clockwise until it locks into place. Do not remove the caps until you are ready to install. This keeps the filter clean and dry.
Reset the filter life monitor: Plug the unit back in and turn it on. Press and hold the filter reset button (usually located on the control panel) for 3-5 seconds until the indicator light changes or resets. This tells the system the filter is new. If you skip this step, the monitor will still show the old filter's remaining life, leading to premature replacement warnings.
Flush the system: Run the dispenser for about 3-5 minutes to flush any air and loose carbon fines from the new filter. The water may appear cloudy at first—this is normal. Wait until it runs clear before using. Do not drink the first batch of water after installation. It may contain fine particles from the new filter.
