Overall Verdict

The Waterdrop WD-FC-01 will be a good purchase for all. With its affordable pricing, high flow rate, and certifiably great filtering performance against chlorine, it’s currently one of the top choices out there value-wise.

The overall design of this faucet-mount water filter is great, with a unique design and installation system. However, its long-term durability can be questionable as it's made from plastic.

The filter is easy to use, like most filters on the market.

Things We Like

  • Excellent chlorine filtration efficiency.
  • High filtering flow rate.
  • Unique design and installation system.
  • Replacement filter is readily available.

Things We Don’t Like

  • While unique, the installation system of the filter is hard to figure out.
  • Plastic construction makes long-term durability a concern.

The WD-FC-01 is the second faucet-mount water filter from Waterdrop that we’ve put to the test. Fortunately, just like its sibling — the WD-FC-06 — this unit also performs excellently.

Despite being at half the price, it still does a great job filtering out chlorine during our performance test compared to all the other water filters we’ve tested. And later, in the flow rate test, the WD-FC-01 had one of our database's fastest filtering flow rates, second only to the Waterdrop WD-FC-06 (as of January 2023).

Analysis and Test Results

9.2 Performance

The overall performance of the Waterdrop WD-FC-01 is very good. In the chlorine filtration test, the filter removed nearly 100% of the free chlorine in the chlorinated water we pumped through it.

As for the filtering flow rate, at 1.29 GPM, the WD-FC-01 is one of the fastest-working faucet filters in our database (second just to its sibling, the Waterdrop WD-FC-06).

9.1 Design

The Waterdrop WD-FC-01 is built mostly from plastic. Although the unit feels solid and high-quality, the plastic construction doesn’t bode well for the filter’s long-term durability.

Waterdrop did a good job at designing the unit’s various components, from the removable filter piece to the marked routing valve and handle.

10 Usability

The filter’s usability isn’t as high as we had hoped. It’s mostly hampered by a lower score in the installation section than most due to having a unique installation system. Instead of a rotating collar like most models, the WD-FC-01 has a removable plastic ring that fastens to a faucet adapter. We had to read the manual (a first!) to know how to put it on correctly.

Besides the problematic installation, the WD-FC-01 is straightforward to use and maintain.
