Filter Replacement Schedule:
To keep your water fresh and ensure continuous filtration, replace your filter every 6 months or after filtering 6,000 gallons, whichever comes first. The actual lifespan may vary based on your local water conditions and usage.
Replacement Procedure:
Follow the installation steps outlined in the 'Setup' section to replace the old filter with a new one. Remember to turn off the water supply before starting and flush the new filter after installation.
Troubleshooting
If you encounter any issues with your Waterdrop 3US-AF01 filter, please refer to the following common problems and solutions:
- Low Water Flow: This could indicate a clogged filter. Check if it's time for a replacement. Ensure the water supply valve is fully open.
- Leaks: Ensure the filter cartridge is properly seated and twisted clockwise until it locks. Check all connections for tightness. If leaks persist, turn off the water supply and contact support.
- Unusual Taste or Odor: If this occurs shortly after installation, flush the filter for a longer period (10-15 minutes). If it occurs after prolonged use, it's likely time to replace the filter.
- Filter Not Fitting: Double-check that you have the correct model (WD-3US-AF01 or WD-W01) for your system. Refer to the model identification video in the Product Overview section.

Understanding TDS
Total Dissolved Solids (TDS) refers to the total concentration of dissolved substances in water. While some believe lower TDS always means better water, this is not necessarily true. TDS includes both beneficial minerals and harmful contaminants. This filter is designed to reduce specific contaminants like chlorine and lead, but it does not significantly reduce TDS.
