1. Product Overview
The Waterdrop WD-PF-01A Plus filter is designed to provide clean, filtered water by reducing various impurities from tap water. This filter is compatible with all Waterdrop pitcher filtration systems, including models WD-PT-05, WD-PT-05-L, WD-PT-07, WD-PT-04, WD-PT-72, and WD-PT-61. It utilizes multi-stage filtration technology to enhance water quality.
The filter employs advanced Activated Carbon Fiber (ACF) technology, offering superior absorption capabilities. It is independently tested and certified by NSF International against NSF/ANSI 42 and NSF/ANSI 372 standards for the reduction of specific contaminants in models WD-PT-04, WD-PT-05, and WD-PT-07. The filter is designed to be lead-free and BPA-free.

2. Setup Instructions
- Preparation: Remove the new filter from its packaging.
- Soaking (Optional but Recommended): For optimal performance, soak the new filter in cold tap water for 10-15 minutes. This helps to remove any air bubbles and primes the filter.
- Installation: Insert the filter firmly into the designated slot in your Waterdrop pitcher's reservoir. Ensure it is seated correctly to prevent unfiltered water from bypassing the filter. The filter should fit tightly to prevent leakage.
- Flushing: Fill the pitcher with tap water and allow it to filter through completely. Discard the first two pitchers of filtered water. This flushes out any carbon fines and prepares the filter for regular use.

3. Operating Instructions
Once the filter is installed and flushed, your Waterdrop pitcher is ready for use. Simply fill the top reservoir with tap water, and the water will pass through the filter into the main pitcher. The WD-PF-01A Plus filter features an exclusively fast flow rate of 0.4 gallons per minute (gpm), allowing for quick access to filtered water. Ensure the pitcher is placed on a stable, flat surface during filtration.
4. Maintenance
Filter Replacement
The Waterdrop WD-PF-01A Plus filter has a lifespan of approximately 3 months or 200 gallons, whichever comes first. Regular replacement ensures continued optimal filtration performance. Exceeding the recommended lifespan may reduce the filter's effectiveness.
Cleaning the Pitcher
Periodically clean your Waterdrop pitcher according to its specific cleaning instructions. The filter itself should not be cleaned or reused beyond its recommended lifespan; it must be replaced.
5. Troubleshooting
- Slow Flow Rate: If the water filters slowly, ensure the filter is properly seated and not clogged. If the filter is near the end of its lifespan, a slow flow rate can indicate it's time for replacement.
- Unfiltered Water or Leakage: If water appears to bypass the filter or leaks occur, remove the filter and re-install it, ensuring a tight and secure fit within the pitcher's reservoir.
- Unpleasant Taste/Odor: If the filtered water has an unusual taste or odor, ensure the initial flushing steps were followed. If the issue persists or the filter is old, replace the filter.
