4. Operating Instructions
The PUR Plus system is designed for ease of use, allowing you to switch between filtered and unfiltered water as needed.
4.1 Switching Water Flow
Locate the on/off lever on the side of the faucet mount. Move the lever to select between filtered water (for drinking and cooking) and unfiltered water (for washing dishes or hands). This allows you to conserve filter life.
4.2 Filter Change Indicator Light
The system includes a filter change light that provides a visual cue for filter replacement:
- Green Light: Filter is working optimally.
- Yellow/Orange Light: Filter is nearing the end of its life and should be replaced soon.
- Red Light: Filter has reached its capacity and needs immediate replacement to ensure continued filtration performance.

Regular maintenance, primarily filter replacement, is crucial for optimal performance of your PUR Plus Filtration System.
5.1 Filter Replacement
The Genuine PUR Plus Faucet Mount Replacement Filter is certified to last for up to 100 gallons or approximately 3 months of regular use, whichever comes first. Always replace with Genuine PUR filters to ensure proper fit and filtration standards.
- When the filter change light indicates replacement is needed (yellow/orange or red), turn off the water supply.
- Press the release buttons on the side of the filter housing and gently pull the old filter cartridge out.
- Insert a new Genuine PUR Plus filter cartridge into the housing, ensuring it clicks securely into place.

5.2 Cleaning the System

6. Troubleshooting
If you encounter any issues with your PUR Plus Faucet Mount Water Filtration System, refer to the following common solutions:
- Low Water Flow: This often indicates a clogged filter. Check the filter change indicator light. If it's yellow/orange or red, replace the filter.
- Leaks from the Faucet Mount: Ensure the system is securely attached to the faucet adapter. Check that the adapter is tightly screwed onto the faucet. If leaks persist, try reapplying plumber's tape to the faucet threads before attaching the adapter.
- Water Not Filtering: Verify that the on/off lever is set to the filtered water position. If the filter is old, replace it.
- Unpleasant Taste/Odor in Filtered Water: This suggests the filter has reached its capacity. Replace the filter immediately.
