What Is The Difference Between RPWF And RPWFE Water Filter?

As various manufacturers nowadays include RPWFE and RPW filters in their fridge products, many consumers might find it perplexing to distinguish between the two filter systems.

So, what is the difference between RPWF and RPWFE water filters regarding quality, price, install, design, capacity, and features? If you are looking for a detailed answer, you’ve come to the right place! Read on to discover!

What Is The Difference Between RPWF And RPWFE Water Filters?

Price Difference

When it comes to price variation, RPWF leads the race over RPWFE. In detail, the sellers often offer the former in a package of 2 at around 50-60 dollars while the latter comes to the market at around 80-90 dollars for a pack of 2. 

Filtration Quality

This section will explain the reason why RPWFEs have become increasingly common, forcing RPWF to yield its first place to its competitor.

Both filters offer outstanding filtering efficacy regarding pollutant filtration quality.

RPWF eliminates 97 percent chlorine, poor taste and smell, corrosion, rust, particles, and turbulence using an activated charcoal block filtering substrate. 

The filtering quality of the RPWFEs, however, is more sophisticated. The filter uses a charcoal-block coconut shell filtering medium to combat 50 pollutants, including arsenic, heavy metals, sediments, chlorine, cysts, bacteria, and other toxins.

The filter is also certified to eliminate 99 percent of perfluorooctane sulfonate -so-called PFOS and perfluorooctanoic acid (or PFOA) and five trace medicines such as progesterone ibuprofen, atenolol, fluoxetine, and trimethoprim.

With such powerful filtering capabilities, RPWFE easily outperforms its prior counterpart.

Filter Longevity And Capacity

Regarding the longevity and capability of both filters, there is not much to distinguish them, as they are quite similar. In particular, both filters provide 300 gallons of purified water that is free of pollutants and pathogens.

Users can change these two filters for half a year or when the filters reach their maximum of 300 gallons. Both RPWF filters and RPWFEs are available in 3, 2, and 1 package sizes. Besides,  purchasing a 3-pack filter will be the best option that can save you time and money compared to the other two packs.

The replacement for a new filter will depend on the water flow rate. If you are confused with something, reach out to the company web for more assistance.


Installation and changing both filters are simple if you follow the correct procedure. Since people go through the same procedure for both filters replacement, there might be some confusion once the new filters didn’t match correctly.

The twist fix technique was used on the RPWF filters, which required twisting the filter within the gap and locking it. Meanwhile, the fresh RPWFE filter deviates from this trend. It’s a lot easier to put together, as you do not have to turn and twist the RPWFE for the fitting. 

You can quickly change the cartridges after you correctly installed the filter.

Verification & Warranty

The warranties of both filters are unclear, so you’ll have to ask the company to find out more and file a claim.

On the other hand, the filters have been tested, confirmed, and validated to meet NSF/ANSI safety requirements to enhance the quality of the water and decrease visible pollutants.

For the elimination of chlorine, sedimentation, arsenic, mercury, and other hazardous particles, the RPWFs have received NSF validation against requirements 42 and 372. Although RPWFE is well-known for its qualifications, the safety requirements remain unknown.


It is hard to tell any apparent difference between these two filters when mentioning their appearance. Still, there is a big variation concerning filter suitability.

The match of RPWFE filters appears to be restricted to GE’s French-door fridge. Also, the RFID chip that the RPWFE filters contain is what makes them remarkable and distinctive.

RFID is the abbreviation for radio frequency identification. It functions as a sensor, informing your fridge about filter longevity, filtering operation, and replacement schedules. 

Value For The Money

If you’re on a tight budget and need a substitute filter for your GE fridge, RPWF is an excellent option due to its small gap in quality. 

RPWFE filter, on the other hand, is significantly more costly than RPWF and offers a variety of sophisticated capabilities beyond simple filtering. Even though it would be of little use to a non-RFID-used fridge, installing an RFID chip to the RPWFE will increase its price.

Yet, both filters perform admirably and offer excellent value for money. Either you pay a little more on RPWFE or save money by using the RPWF; they are all worth your money! 


With the release of the newer RPWFE models in 2017, the existence of RPWF filters will probably fade away. However, the modern filters are far more expensive, leaving many individuals questioning whether the additional expense is worth the expense. So, a chance is still there for RPWF.

You won’t have much of a choice if you possess a newer GE refrigerator. The RPWF model filters will not work in fridges that are designed to utilize the RPWFE filters. The RPWFE, on the contrary, is interoperable. This implies that you can only use a newer filter in an older refrigerator.

In case your refrigerator does not need one, you may choose not to pay the extra money on a modern RPWFE filter because they’re way more pricey.

Internal Feature

As radio-frequency identification-so-called RFID chip in the RPWFE involves linking features with your fridge, the filters and the refrigerator function and link together.

Although it would be best to replace your water filter every six-month of use for optimum water quality, the RFID chip may inform you how much time the filter will last. The device can also notify you if a leak happens in your fridge system, which may help you avoid unnecessary damage and fixes.

RPWFs are not compatible with current new refrigerators due to the RFID. Older General Electric fridges can utilize the RPWFE filters, but they lack a touchscreen interface or other devices to access the RFID chip.  Thus, RPWFE filters are useless in older designs.

Since the RPWFEs are more costly than the RPWF filters, several consumers have attempted to modify the older filters to operate with the latest refrigerator. The RFID chip, which communicates with the modern fridge to filter and deliver water, is crucial.

Despite all freezers having a bypassing cartridge, you can choose the water dispensers even if you’re not using a filter; they will not process the liquid.

A Quick Rundown Of RPWF and RPWFE

Can RPWF And RPWFE Water Filter Remove Pesticides?

Although RWPF is not guaranteed to eliminate pesticides, RPWFE promises to lower apparent pesticide levels and other pollutants.

How Do I “Hack” GE Fridge?

RPWFEs are much more expensive than older RPWF filters with few discernible variations. It stands to reason for saving the dollars by utilizing the older model filter, even when you have a modern GE refrigerator. There is a method to use the older type filters, even though they aren’t theoretically compatible.

In detail, the RFID chip included in the RPWFE is removable. You can make your refrigerator grab a new RPWF filter by inserting the RFID chip from a modern RPWFE filter to that RPWF filter.

 However, there comes a disadvantage:

The new RPWF won’t serve as a new filter because it has the exact RFID chip that your refrigerator already uses. Hence, the “replace filter” alert light will stay illuminated even if the filter is completely fresh. If you can get beyond this small irritation, you could save a lot of money on new RPWFE filters by using this simple trick.

How Do I Know If My Refrigerator Filter Needs Replacement?

The finest fridge filters have a six-month lifespan. The flow rate of water, on the other hand, may allow you to know when it’s time to replace the filters.

The Final Verdict

Hopefully, after reading this post on “what is the difference between RPWF and RPWFE water filter,” you have learned some key distinctions between these two filters.

You can purchase an RPWF filter or learn how to “hack” the system for those on a tight budget. Otherwise, RPWFE is ideal for purifying the water and many other benefits, given a higher selling price.
