If you're looking at the reviews, you'll see many that hate this filter complain about slow water flow. Googling the issue with this filter you'll see it's really common on many other sites. After many years of dealing with this, GE has finally rolled out a newer design. Not sure when this happened, but Home Depot in the Chicago area started to carry the newer ones summer of 2014. I waited until my 2nd filter to now leave a review here (deleted my old review since I couldn't figure out how to add image while updating an old review).

Anyways, the new filter is GOOD with EXCELLENT water flow. Just like when fridge was new. I recommend you buy it in person at Home Depot so that you know you're buying the new design. How do you tell the difference, please see the images in this review. First, the box will look different. Box design has MWF in bold black print and "splash of water" in bottom right. The old packaging was green and blue. Second, to confirm the new design see the comparison image I added. Notice the new design has 2 tabs that protrude from what was the flat area of the old filter. This is consistent with an old hack for the filter (that worked for me) of cutting out a plastic "washer" that assisted in pushing in the pointed button where the filter connects to. You can see this "pointed button" when you take out the filter and look at the filter head. If you push that in, you'll see that is where all the water supply enters the filter. It was suspected the old design either did not depress that fully or the filter being flush just blocked the water supply some. If you're wondering why the fridge wasn't like that when you bought it, it's like it was using the even older design made by Culligan. You can google the info on that, but basic Culligan made the filters and there was a dispute between the 2 companies.

Anyways, I hope this helps clear up the mystery for some folks.

I really like the simplicity of this filter. You don't need to turn off anything to install it and you can easily do with with you bare hands without using specialized tools. It has never leaked and does a great job providing water filtered through activated charcoal for about 6 months. I had to admit I was curious about what was inside so I opened an old unit open to check it out. I included an image in the media section. GE uses an interesting approach with this filter. Rather than using a mesh screen with activated charcoal particles in an inner sleeve, they developed a solid, fused charcoal plug that must serve as both the particle and chemical filter. The filter canister is really thick-walled so I imagine it can withstand even intense water pressure. All and all a great product.

Shipped immediately, took it out of the box, ignored all the instructions and warnings as men do, unscrewed the other one, put this one in, filled up 2 big glasses of water to "flush it" and that was it.

Maybe 5mins worth of effort?

Not sure what else to say in a review of this item, worked great in our GE fridge.

This was the same filter I could have ordered from GE directly, but at a much better price.

I read some of the negative reviews and gave this a try anyway. Fearing that I may end up getting a used repackaged product (as mentioned in some of the negative reviews) I made sure to pick up a TDS* water meter/tester as well. Not only to make sure I got a new filter from this seller, but also so I can test the various liquids used around my home.

As I'd mentioned in my review for the TDS* water meter/tester, my tap water is hard so I used the baseline measurement (PPM's) of a bottle of Poland Spring water. My main concern about this filter or my refrigerator water line in general, was that it wasn't going to make too much of a difference drinking water from the tap versus one that came out of this filter. After my baseline measurements, my concerns were put at ease.

Below are results from my tests:

(measurements in PPM)
0-50 = Ideal drinking water
50-100 = Carbon filtered water
100-200 = Hard water
200-300 = Marginally acceptable
200-400 = Average tap water
400+ Very high TDS contaminant level

--My household baseline--
Bottle of Poland Spring = 18
Tap Water = 281
Gatorade = 260
5 month old filter from my refrigerator water line = 240
New filter from my refrigerator water line = 200
Melted ice (4 hours) = 293

So what did I learn from this... My tap water isn't too bad, this particular filter can probably go another month or two, and I really need to clean my ice maker. The good news is that this filter removed 80+PPM's of TDS* from my tap.

*TDS* - Total Dissolved Solids are the total amount of mobile charged ions, including minerals, salts, or metals dissolved in a given volume of water.

Water passing through this filter was painfully slow. We waited patiently hoping the water pressure would increase over time. After several months, I called the GE answer center. They had me remove the filter and use the by-pass plug. The water pressure was normal without the filter installed, so the problem was the filter.

Then I got the bad news. GE says Amazon is not an authorized retailer and they would not replace the filter. They said "Don't ever buy them on-line because we can't guarantee the quality." I hope Amazon will work with GE to resolve this issue.

Six months ago I ordered one sold by Amazon and it worked great with my fridge.
A week ago I ordered another one and did not notice that is not sold by Amazon. At first I thought there is no big deal, it was prime eligible so it arrived on time.

I received the package and I noticed something is not right when I tried to replace it. The two filters do not look the same.
So I immediately went to Home Depot to buy another one to see which of them is bootleg.

I have three photos here:
Photo 1 - the boxes:
Left - from Appliance Cove, Right - from Home Depot.
Left one is a bit smaller. An extra label is there hiding the original barcode. The barcode on top does not match anything from Google search.
Right one is a bit bigger. Search the barcode on Google will return you it is GE MWF water filter.

Photo 2 - the filter:
From left to right: from Amazon, from Appliance Cove, from Home Depot.
You can notice that the print of the center one is worse than the others.

Photo 3 - the filter again:
From left to right: from Amazon, from Appliance Cove, from Home Depot.
Again the center one does not look same as the others. The align arrow does not align and it is shorter than the others.

Clearly the one from Appliance Cove is a bootleg product.

I was a little worried about changing the filter as I'd never done it before and wasn't entirely sure this was the right filter. Returns with Amazon are really easy, so I just bought it and two days later it was here (thanks to amazon prime). The instructions were simple and very easy to follow. They include simple instructions for removing the old filter without breaking anything. The water tasted TONS better immediately. The filter was less expensive on amazon than in the local stores. I can't think of a reason to give it less than 5 stars...

You just can't go wrong buying original manufacturer GE refrigerator water purification cartridges actually made by GE. Since they're fully enclosed (and consequently you will never know exactly what's inside) you should be able to trust the original manufacturer, who has a reason to make high quality replacement parts so that you don't think your fridge is defective. On the other hand, refrigerator owners need to know that your GE fridge is programmed to notify you to replace the cartridges every six months WHETHER OR NOT you need to do so. We've easily gotten more than a year out of each cartridge; you can tell it needs replacement when the water doesn't taste quite as fresh as it should. I like to keep an extra cartridge on hand in case I need one quickly, but so far that has never happened. Happy Hint: Write the date you replace the cartridge on the cartridge itself with a black sharpie pen, and that way you will know exactly how long your cartridge lasts (which can vary according to the water supply you are using).

I have 2 GE refrigerators, both under 2 years old. I purchased 2 of these replacement filters...and an HM water meter, to see how good the the filters work. To my extreme surprise, the water filters remove nothing from the water, the contaminent levels are equal with the tap water in each of my two houses!!! I ran gallons of water through the filters and the readings never went down. So I called GE, customer service informed me there was a small chance I could have received 2 defective filters, and I should try to return them to Amazon. I tested the HM water meter on bottled water that is supposed to be very pure, and it was. Arrowhead water is at a "marginally safe tap water" level. My neighbor's reverse osmosis worked well. (I highly recommend everyone get a water meter...especially if you are putting any kind of trust in these GE filters!).
