DuPont Faucet Mount Water Filter (WFFM100XCH) Review

Thinking of upgrading your kitchen with a faucet filter? The DuPont WFFM100XCH faucet mount filter should make for a pretty good choice!

Overall Verdict

The DuPont WFFM100XCH is a decent faucet-mount filter. But while it certainly does the job, having passed our chlorine filtering test with an excellent score and a passing score in our flow rate test. However, there are better options out there on the market for the price.

Our main concern is the filter of the DuPont WFFM100XCH, having a fairly low filtering capacity of 100 gallons. There are cheaper models on the market that offer roughly the same amount of capacity while being just as capable (when it comes to chlorine filtration).

Things We Like

  • Chrome-plated design gives it a sharp appearance
  • Excellent chlorine filtering capability
  • Decent flow rate
  • Easy to install and use

Things We Don’t Like

  • 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

DuPont is a household name around the world. Although it’s not known for its residential water filtering systems in the same manner as PUR or Brita, surprisingly, DuPont’s faucet-mount water filter did pretty well in our tests.

The DuPont WFFM100XCH passed our chlorine filtration test with a perfect score. Though it didn’t do quite as well in the filtering flow rate test, its test results are pretty impressive compared to other models we’ve tested.

Analysis and Test Results

6.8 Performance

Performance-wise, the DuPont is a mixed bag. While it performed excellently in the chlorine test and removed virtually all traces of the chemical in the highly-chlorinated water that we pumped through it, it didn’t do quite as well in the flow rate test.

We attached the filter to a 2.2 GPM faucet and measured an output flow rate of just 0.46 GPM once it was switched to water filtering mode. This is lower than our passing minimum of 0.5 GPM, so the DuPont is one of the few faucet filters that failed our flow rate test.

8.4 Design

Although the DuPont WFFM100XCH has the appearance of a metallic filter, it’s actually constructed from plastic. Though the overall build quality is solid, and we haven’t found any issue with the design, its long-term durability may be less than filters made from stronger materials like stainless steel.

The filter cartridge that comes with the filter has a mediocre capacity of 100 gallons, which will last for around 1-2 months before it has to be switched out.

9.7 Usability

If you’ve ever used a faucet-mount water filter before, the DuPont WFFM100XCH won’t be any different than your old one. After you’ve fixed it to your faucet, the only motion that you need to learn is switching the routing valve’s handle back and forth to select between unfiltered and filtered water modes.

Once every 1-2 months (depending on how much water your household use), you have to replace the spent filter cartridge with a new one to maintain the filter’s efficiency. The replacement process, blessedly, is simple.
