How Does Our Team Choose Filter Cartridge?

We test the best and worst water filter cartridges for DuPont and other brands and share our results in this in-depth review.

Surface Filter Cartridges

Filtration along with surface filters preserves space on the top of the filter membrane. Sheets of nylon or Teflon, and polypropylenes are bonded and pleated on ends for giving a big filtration area.

The pollutants are trapped on the surface of the sheet making a layer that may aid filtration in itself.

Since the pressure drop rises, the filter cartridge may be removed from the filter housing and washed off. The merit of using a surface filter is that it may be washed off and cartridges are possible to use again.

As pleated filters are being used for coarse pre-filters, normally the range is 30 to 500 microns.

They are also applied in submicron applications since they give consistent and finer filtration for definable pore structure and size.

Filtration ratings for pleated surface filter cartridges may be anyplace between 50 microns down to 0.04 microns absolute that are applied in pharmaceuticals or semiconductor water filtration.

Compared with a depth filter; a surface filter may have higher filtration to repair the absence of depth. Filtration space may go high as 11 square feet in a normal 10″ x 2.5″ cartridge or higher.

Filters can be installed in series

Suppose one can use a 50-micron pleated filter to remove big particles. This type of filter may be reused and washed. After that 50 micron filter, a 50-micron depth filter is used to remove particles from the water. By having the 50-micron filter first, the filter will last for a longer time.

Depth Filter Cartridges

Deep filters are normally seen as wound spun, string, or melt-blown cartridges which hold big size particles on the surface and smaller particles beneath the surface down to the center core.

They are working well when verities of particle size are filtered. The work of the depth filter is to abolish more sediment and catch more sediment in general except losing pressure instead of a top filter cartridge.

Whole Filters vs. Cartridges

A whole filter usually costs more because there are fewer parts involved. However, an entire filter may last longer as well. On average, a whole filter should cost about half what a cartridge does. There are many advantages to using a whole filter instead of a cartridge.

You don’t have to worry about replacing the filter every month since a whole filter can last much longer than a cartridge. This means you won’t have to pay for consumables like cleaning and maintaining cartridges. Lastly, you can choose which type of filter works best for your needs. Some people prefer whole filters, while others prefer cartridges.

How To Change A Whole House Water Filter – DuPont

Frequently Asked Questions (FAQs) about DuPont Water Filter Cartridge Review

How often do I change my cartridge?

Saving money can be achieved by considering changing your cartridge once per year. If you live where tap water is low in contaminants, you can get away with this frequency. The most frequent cartridge replacements would be California, Florida, Hawaii, New York City, Texas, and Washington DC.

What type of water does my faucet come equipped with?

If your faucet comes equipped with hard water, you should look into replacing your cartridge every six months. Hard water tends to contain high concentrations of minerals like calcium and magnesium. When combined with soap, these minerals form scale deposits on the internal parts of your faucets. Over time, this buildup causes leaks and clogs. Replacing your cartridge regularly prevents this problem.

Do I need to buy a new cartridge?

You don’t necessarily need to purchase a brand new cartridge when you’re ready to switch out your current one. However, there’s no harm in doing so. It depends on what kind of cartridge you currently own. Some brands last longer than others. For example, the Durafilter Plus lasts about three times longer than the standard Durafilter.

Is it safe to drink unfiltered tap water?

It is fine to drink unfiltered water. You’ll likely enjoy drinking straight from the tap if you’re worried about filtered water’s lack of flavor.

Does my home already include a water softener?

There’s no need to worry if your home already includes a water softener. Most homes built before 1990 were installed with a water softening device.

Can I reuse old cartridges?

Yes! be sure to follow the instructions provided by the manufacturer.

Are all DuPont water filter replacement cartridges compatible with my system?

All DuPont water filter replacements are made for their respective models.

Will using another brand of water filter affect the performance of my existing cartridge?

No. All DuPont water filter replacements work together seamlessly.

Which model should I go with?

There are two main options available. You can replace the whole cartridge at once with the DuPont AquaSana Advanced Faucet mount. Installing this way is easier since you only have to remove one part instead of several screws. DuPont Aquasan Premium Faucet Mount replaces only the top part of your cartridge. Both versions allow you to swap between them depending on your needs.

Should I buy an extra set of cartridges?

This decision depends on your budget. It may seem expensive to buy extra sets of cartridges, but it may prevent future problems.

Final Words of Recommendation

As we have seen in this DuPont water filter cartridge review, it is no doubt that DuPont offers one of the most advanced water filtration systems. The company has been continuously innovating water filter systems to help make its customers’ lives free of disease-causing pollutants.

Both water filter systems certainly have outstanding qualities with attractive and affordable prices. However, if you have a small family that consumes about 2 gallons of water in a day, we recommend getting the DuPont WFPTC102 pitcher cartridge. But if you have a large family, DuPont WFQTC70001 is just perfect.
