DuPont WFFM100XCH Faucet Water Filter {Updated May 2024}

In this DuPont WFFM100XCH review we break down why we love this water filter. While we are generally led to believe that the water that arrives in our taps from the city mains is safe to drink, there is a big difference between “safe” and “clean”. Because human beings and animals rely on clean pure drinking water for their health and well-being, this may be somewhat unsettling for some people.

The good news is that the quality of your drinking water can be improved with the addition of a faucet water filtration system.

If you have been tentatively eyeballing your glass of water wondering what else is in there other than pure H20, this article is for you. Here we will discuss the DuPont WFFM100XCH Faucet Mount Drinking Water Filter, how it works and how it can benefit you and your household. So, let’s get started.


What is the DuPont WFFM100XCH Water Filter?

The Faucet Mount Filter from DuPont is a water filter that noticeably improves the quality, taste, smell, and purity of the water coming from your kitchen faucet. In addition to top-notch performance, it looks terrific and won’t take up much space on your kitchen sink.

DuPont’s filter has been specially designed to reduce the levels of pollutants and contaminants that are present in most water supplies. This includes filtering out asbestos, mercury, lead, sediment, benzene, and chlorine. These contaminants are often found in city water supplies and well water. Even though they might not kill you, they can certainly deteriorate the water quality and a good filter will make drinking water more pleasant in every way.

The filters included in this superior water filtration system can purify as many as 100 gallons of water. This means they will clean about 2-months’ worth of drinking water before they need to be replaced.

The DuPont Faucet Mount Drinking Water Filter can be connected to just about any type of faucet directly. If your faucet is especially unique, there are adaptors included in the system that can be used to make a good connection. Everything else you could need to set up your filtration system is also included in the unit, including washers, faucet mounts, and even proper plumbing tape.

Features of the DuPont WFFM100XCH Water Filter

The DuPont 100-series filter works to reduce the number of contaminants in your water supply including lead, asbestos, chlorine, sediments, cysts, and mercury. Each filter will last about 2 months and clean 100 gallons of water before they need replacing.

Faucet mount & filter housing

The specially designed mount connects the filter housing to the faucet mount. It can be screwed into the filter housing and is fairly simple for anyone to connect. The filter and housing unit are made of durable materials and can be expected to last far longer than most other options in its category.

2 Faucet Adapters

Most faucet filtration systems you will find on the market come with 4 adaptors, so you may find that neither of these fits your faucet. But you can contact the manufacturer to check if the filter will be the right match for your needs before you even set this up. This will save you the hassle of having to shop around for another adaptor after making the purchase.

Installation parts

There will be no need to run around looking for parts and pieces for connecting your DuPont Faucet water Filter as this option comes with everything you could need. You will find washers, adaptors, and plumbing tape as needed, plus some to spare.

Installation instructions

There is really nothing difficult about the setup for this filtration system and it can be completed within about 10 minutes, even with zero DIY experience. You will find a handbook with detailed instructions on how to perform this fairly simple task.


The DuPont WFFM100XCH Water Filter is a little more expensive than many of the other options found on the market so you will hope that the performance will stand out in some way.

But what you are paying for more than anything else is the superior quality and craftsmanship of the filter housing unit. In many ways, this does improve the quality of the product by protecting the inner workings of the filter and providing extra longevity to your product. You can expect this item to last far longer than many of the other options that include cheaper plastic housing that can be easily damaged with all the activities that happen in and around the kitchen sink.

As far as performance goes, the DuPont WFFM100XCH is a fairly standard filtration system. You can expect a solid 100 gallons of pure water from each filter cartridge, which is not the most impressive amount on the market. But you will still get about 2 to 3 months of clean water from each filter and this is pretty good. Furthermore, you can find some better filters that will fit the device and this means you can take advantage of that superior housing to protect a longer-lasting filter.

Installation & Maintenance

Installation for the DuPont WFFM100XCH Faucet Drinking Water Filter is simple. Simply hook it up to the faucet by following the included instructions and then allow the water to run for about 2 minutes to properly flush the filter system.

The biggest problem you will face is that there are only 2 different filter adaptors to connect to your faucet. This is not a very extensive range of options if you have a very unique faucet in your kitchen. The simple solution would be to check online for another adapter if you see that neither of these works. But the best idea will be to check with the manufacturers before you make a purchase.

Unlike many other faucet filtration systems that have an indicator light that will alert you to the need to change the filter, this item is pretty simple. But not to worry, you will certainly notice when it is time to change the water filter as the water flow will become greatly reduced after a certain amount of time. Then just pop open the housing unit, pull out the older filter and throw in the new one — a very simple process.

Filter Info

The DuPont 100-Series Water Filter is WQA certified to reduce the quantity of lead, sediment, cysts, and asbestos that can often be found in urban water supplies. It can also eliminate many of the contaminants that affect the taste, smell, and even feel of the water. It is important to note that this filter will not remove chloramines from the water. For this reason, it is always good to begin your quest for pure water with a clear idea of which contaminants are present in the water so you can purchase a suitable water filter.

Another good point to keep in mind is that the DuPont manufacturers suggest the DuPont WFFM100XCH Faucet Mount Drinking Water Filter be only used to purify water from city mains. This product is not recommended for use with well water. This is because the DuPont filtrations system is not designed to remove ions that can cause limescale, or the minerals commonly found in well-water like magnesium and calcium. Like the vast majority of water filters on the market, the DuPont Faucet Mount Drinking Water Filter is only designed to improve the taste, smell, and appearance of the water.

But you will be happy to know that the DuPont manufacturers are constantly designing and upgrading their filtration systems and there is a good chance that there will be more advanced filters soon that provide special benefits to a wider range of water supplies. Just keep in mind that the performance of different types of water filters will vary.

Filter lifespan isn’t the longest and this can be a problem for households that use a lot of water

Frequently Asked Questions

Q: Does this Water Filter only run filtered water?

A: You will be able to conserve the longevity of your filter by switching between filtered and unfiltered water with the flip of a switch. This means that dishwashing and other tasks that do not require filtered water can be done with regular water. Furthermore, you don’t want to use hot water with this filtration system as this could damage the filter.

Q: Will the filter reduce water flow?

A: The DuPont WFFM100XCH Faucet Mount Drinking Water Filter will reduce the flow of water marginally. This is caused by the extra time water takes to pass through the filter and have contaminants removed. But a regular-sized glass can be filled within about 10 seconds.

Q: Is there an indication for replacing the DuPont filter?

A: The DuPont WFFM100XCH Drinking Water Filter should be swapped out after every 100 gallons of water. Of course, it is unreasonable to assume you will be able to count that much water being used. The best indication that the filter has been spent and it is time to change it out will be when the water flow has slowed and it takes anywhere from 20 to 30 seconds to fill the same glass of water that took only 10 seconds initially. This means that the filter has reached a maximum capacity of contaminants and is no longer functioning as intended.

Q: Does this filter function on a pull-out spray hose?

A: No, this product is designed to work with a bar faucet only. Actually, you will probably not find a faucet filter system that works with the pull-out hose. For this, you will need the under-the-counter option.

Q: What should I do if the unit doesn’t fit my faucet?

A: Two adapters come with a filter that can be applied to your faucet. If neither of these adaptors works, you can either look online for another adaptor or check your local hardware store and see if they have an option for you.
