Over the years, the refrigerator has become a must-have appliance in every home. The appliance is suitable for getting cold water and storing your food.
The GE® is the top choice when it comes to experiencing the best refrigerators. But even the best refrigerators need filter replacements. And this is why this blog discusses all you should know about the RPWF and RPWFE filters.

How the RFID Chip Distinguishes the RPWF and RPWFE Filters

Although the RPWF and RPWFE water filters have several differences, the most phenomenal one is the radio frequency identification (RFID) chip on the back of the E which tells when to change the filter and supposedly detects leaks.
The RFID chip communicates with a GE® refrigerator, validating it as a genuine product. For a non-genuine or old (more than 6 months) GE® RPWFE filter, you will see a message on the display screen suggesting that the refrigerator cannot dispense water at the time.

Other Differences Between RPWF and RPWFE

The RPWFE filter is an upgrade to the RPWF filter.

Filtration Performance

Because the RPWFE filter is an upgrade, it has a better filtration performance.
The RPWF filter has an activated carbon block for filtering water and removing up to 97% chlorine and other impurities, including bad taste and odor, corrosion, turbidity, and sediments.
The RPWFE filter, on the other hand, has a more advanced filtration quality. The filter uses a carbon block coconut shell to fight against several water contaminants, including mercury, lead, cyst, microbes, and chlorine.

Service Life

The lifespan of the RPWF and RPWFE filters are comparable. They filter up to 300 gallons of water, removing harmful contaminants and impurities.
Once the filters reach 6 months or exceed their 300 gallons limit, it is best to change them. Fortunately, since both filters are available in packs of one, two, and three, you can save more money and relax for more than a year by buying the 3-pack filter.

Installation Procedure

Installing and replacing the RPWF and RPWFE filters is relatively straightforward.
The RPWF filters feature a twist fix technology. As a result, you have to twist the filter inside the slot during installation and lock it.
The RPWFE filter, on the other hand, is much easier to install. Since it does not feature the twist fix technology, you don’t have to twist and turn it during fittings.

Filter Compatibility

The RPWF and RPWFE filters have similar designs; you may not be able to tell them apart when you see them together. Nevertheless, the two filters are compatible with different refrigerator models, especially the General Electric (GE®) brand.
It is important to note that new GE® fridge models may only be compatible with new RPWFE filters. Also, refrigerators designed to use the RPWFE filters are incompatible with older style filters.
Nevertheless, the RPWFE filters are backward compatible. You can use a new filter model on an older fridge but not vice versa.
If your fridge does not require an RPWFE filter, you may not purchase one since they tend to be more expensive.

Where to Get RPWFE Filter at a Lower Cost

The new RPWFE filters became available in 2017 as an upgrade to the old RPWF filters. Unfortunately, the RPWFE filters are considerably costlier.
Replacing the water filter of a GE® refrigerator is quite cheap. For example, the GE® RPWFE water filter costs as much as $50, and these costs add up when you change your filter every six months.
A significant challenge is that most GE® filters have an RFID chip which prevents replacements with cheap water filters. Usually, a GE® refrigerator will not recognize generic RPWF water filters from other brands.
Fortunately, Maxblue has a solution to this problem.

Maxblue Replacement for GE® RPWFE Refrigerator Water Filter (with CHIP)

Authoritative NSF Certified

The Maxblue refrigerator water filter has the NSF 401&53&42 certification, certifying that it reduces several water contaminants. In addition, the filter has an NSF 372 certification assuring that the filter is lead-free. These multiple certifications validate the product’s quality and effect.

Perfect Fit

The filter has a built-in chip that makes it fit perfectly with the GE® refrigerator without fears of misinformation. Furthermore, Maxblue’s research team is working diligently on producing perfect fit refrigerator filters with exquisite designs and no leakage issues.

Excellent Filtration

The Maxblue filter effectively reduces water impurities, including cadmium, heavy metals, VOCs, Chlorine, THM, and odor. In addition, the filter’s precise filtration effect provides purified and safe drinking water. A third-party lab tests the data backing the filter’s performance.

Premium Material

The filter’s filtration media is a 100% coconut shell carbon block. Compared to other carbon blocks, this media has a larger surface area and more micropores, increasing its adsorption effect and improving water taste.

Monthly Installation Stickers

The filter comes with monthly installation stickers that indicate when the filter needs replacement. You only have to stick the stickers to the water filter, and you are good to go. Although the filter life is six months or 300 gallons, it may vary depending on the water condition.

Easy Installation

Time is precious. Therefore, Maxblue aims to save your time through its tool-free refrigerator filter replacement. As a result, you can always complete the installation within a few minutes.


All Maxblue products, regardless of size, pass through extremely high-standard examinations. These examinations ensure that the product is top of the range in the market. Even better, Maxblue takes responsibility for all products even after leaving the factory.
We hope this blog helps you understand the key differences between RPWF and RPWFE water filters.
