DuPont WFPF13003B Review

Well water may seem more appealing than heavily treated water from the city but it actually comes with its own drawbacks. Well water often carries high concentrations of rust, dust, sand and other sediment particles. These often affect the taste, odor and overall quality of water.

To make matters worse, these sediment particles can do serious damage to your dishwasher, boiler or washing machine. If you’re in this situation or just want to prepare for the worst, then a sediment filter should be at the top of your shopping list.

DuPont WFPF13003B Review

The WFPF13003B whole house water filter from DuPont is an efficient and easy to install sediment filter. This model does a good job of keeping water free or dirt, rust, and sand by not allowing these contaminants to enter your plumbing and reach your appliances.

The WFPF13003B from DuPont is a point of entry (POE) water filter. What this means is that it begins the filtering process at the water main before it splits into different lines and reaches all faucets and appliances in your house. It improves both the drinking water and the water that goes into your heater or your washing machine. This way, you increase the longevity of your appliances.

Who is this water filter for?

Like most sediment filters, the DuPont WFPF13003B is a must-have for households that rely on well water or municipal water with a high concentration of sediment contaminants. It is not a good choice for removing chemical or bacterial contaminants from water. If your water analysis shows concerning results of heavy metals or pesticides this sediment filter won’t fix your problem on its own.

The WFPF13003B is easy to install and easy to maintain. If you’re not the type of individual with a background in plumbing, you don’t need to worry about it. The filter has a good capacity and only requires you to change the cartridge every six months or so.

You might also find this a useful product if you are particularly worried about dirty water damaging your appliances. Water heaters, toilets, washing machines and dish washers benefit greatly from sediment-free water. Installing this water system filter at your water main will save you the trouble of purchasing multiple units to protect appliances individually. This makes it a very cost-effective choice.

What’s included?

  • Standard 10” filter
  • Poly block cartridge
  • Installation instructions
  • Filter wrench

Overview of Features

Let’s take a closer look at what makes the DuPont WFPF13003B a good whole house sediment filtration unit. First of all, it uses a standard 10” filter. This is not only great at keeping away large particles, but it is also quite interchangeable. You can use almost any 10” filter with this unit, from most popular brands.

The 15,000 gallons filtration capacity is good for small houses, offices and even RVs. You can achieve a 5 gallon per minute flow which is often more than enough for small families.

The standard 3/4 inch inlet and outlet allow this unit to be fitted in almost any household. One minor inconvenience is the lack of a clear casing. Although the filter has a good capacity, the cartridge may need replacing sooner if your water quality is poor. Since there is no visual indicator you will have to manually check the state of the filter from time to time.

The installation process becomes significantly easier once you understand that this water system filter is meant to be used as a POE filter. You should always install it on your main water line before the water splits into cold and hot. Never use it on a hot water line because the filter is not built to withstand the heat.

Before you do anything with it you should turn off your main water supply. You might want to also drain your pipes by turning some faucets on and off.

The WFPF13003B measures 13.8×6.4×5.4 inches. Measure carefully how much pipe you need to cut, and how much wall space you need. Leaving enough room is important if you want to have easy access when it’s time to change the cartridge. The filter doesn’t come with a mounting bracket but it only weighs 2.1 pounds so you shouldn’t need a complex system to support its weight.

Since the filter has 3/4” inlet and outlet ports you shouldn’t have a problem connecting it to your main pipe. If for some reason the seal doesn’t feel tight enough, try using some Teflon tape to make it leak-proof instead of twisting too much.

Note that if you already have a POE filtering system and you wish to add the WFPF13003B in line with the others, you should connect this model first in line. As a general rule, sediment filters are always the first in line and usually, carbon filters go last. If you are also using a UV filtration unit, then the carbon filter would become second to last.


While the WFPF3003B filter has almost everything you could want from a sediment filtration unit, the more expensive WFPF38001C, also by DuPont, has some additional features.

The WFPF38001C has a clear plastic casing that allows you to check the wear on your filter. This comes in handy should your filter begin to lose its efficiency.

Another improvement over the WFPF3003B model is the built-in bypass valve. Not everyone is thrilled about bypass valves on filters as they don’t tend to be very durable. If, however, this is something you simply must have, you can go for the WFPF38001C. Of course, it would be cheaper to just buy a bypass valve and install it on your WFPF3003B.


The DuPont WFPF13003B is a great sediment filter unit. It is easy to install on your main water line and it ensures sediment-free drinking and washing water. At the same time, it cleans your water before it splits into cold and hot circuits, so it has a great impact on your appliances too.

The 15,000 gallon capacity of the filter is good for small homes or RV’s. With normal usage, you won’t have to change filters more than two times a year. The standard 3/4 inch inlet and outlet make this filter a good fit in any household by itself or in line with other filtration units.
