The DuPont WFFM100XCH and the Waterdrop WD-FC-06 are among the most popular and well-rated faucet filters on the market. So, which is the better filter to choose for your kitchen?

Well, long story short, according to our tests and reviewers’ opinions: the Waterdrop WD-FC-06, although pricier, will always make for a better investment than the Dupont WFFM100XCH.

Performance-wise, the Waterdrop model definitely win out over the DuPont. With a perfect chlorine filtering score (10/10) and being the model with the highest flow rate in filtration mode (1.3 GPM when mounted to a 2.2 GPM high-flow faucet), its performance can only be described as “excellent.”

On the other hand, while the DuPont WFFM100XCH also got a perfect score in chlorine filtration (10/10), it has some of the slowest filtering flow rates in our database. At 0.46 GPM, the DuPont even failed our flow rate test due to having a flow rate lower than 0.5 GPM.

In terms of build quality, the Waterdrop WD-FC-06 also showed itself as the better product with a solid stainless steel housing. Meanwhile, the DuPont WFFM100XCH has a pretty, but definitely far less durable housing due to being made from chrome-plated plastic.

Overall, even though the Waterdrop WD-FC-06 is a fair bit pricier, we highly recommend splurging a few extra bucks on it over the DuPont. The value’s just all around better!

Pros & Cons

  • Chrome-plated design gives it a sharp appearance
  • Excellent chlorine filtering capability
  • Decent flow rate
  • Easy to install and use
  • Excellent filtering flow rate (1.3 GPM).
  • Near-perfect chlorine filtration efficiency.
  • Great build quality using 304 food-grade stainless steel.
  • The routing valve is solid and easy to use.
  • The filter has a very low maximum filtering capacity (100 gallons)
  • Only has one nozzle, so it’s hard to know what mode the filter has been switched into until you look at the routing valve’s handle
  • Lacks filter replacement indicator.
