If your refrigerator features a built-in water dispenser and/or ice maker, it’s almost guaranteed to use a filter to ensure that the water is clean and tastes fresh at all times. Of course, this water filter needs to be changed every now and then.
The question is: Does it make sense to buy an expensive OEM replacement filter or is a cheaper aftermarket model more than enough? What’s the difference anyway, except for the price? And what about inline water filters as a completely different alternative? Well, you’ll get all the answer in the guide below.
Let’s find you the best refrigerator water filter!

In our opinion, the best refrigerator water filter in 2023 is the Clearly Filtered Universal.
As an inline water filter, the Clearly Filtered Universal is compatible with every single refrigerator brand and model that exists. So once installed, you no longer need to use the original filter that comes with your refrigerator. You can either bypass it or take it out completely, or simply use the Clearly Filtered as an additional layer of protection.
Why use this inline water filter instead of a genuine refrigerator water filter? One word: Effectiveness. The Universal Inline Fridge Filter outperforms every single of the refrigerator filters reviewed below – branded or not. That’s because it uses more filter stages and more types of filter media which allows it to target more types of contaminants and remove them more effectively (in terms of overall reduction rates).
If clean drinking water is at the top of your priority list, this is the way to go!

Off-Brand Filter Replacement: Waterdrop WDP-DA29-00020B
Obviously, Samsung recommends you to purchase nothing but genuine Samsung refrigerator water filters for “authenticity and guaranteed performance“. However, we don’t mind opting for a more affordable imitation as long as it’s compatible and delivers the same or even better water quality.
One of these imitations is the Waterdrop WDP-DA29-00020B. You can already tell by the name that it’s pretty close to the original – which it is! Same filter media (coconut shell activated carbon block), same filtration capacity, same installation process, 100% compatibility guarantee without leakage.
But what about the water quality? There’s no difference! This aftermarket refrigerator water filter, too, is tested and certified by NSF International against standards 42, 53, and 401.
So all in all, you can expect the same results. However, Waterdrop replacement filters are much more affordable thanks to factory direct selling. In addition, you get a 30-day money-back guarantee and free shipping.
This Samsung water filter is compatible with side-by-side and french-door refrigerators.

Off-Brand Filter Replacement: Waterdrop WDP-DA29-00003G
This is the second refrigerator water filter by Waterdrop that serves as a substitute for a genuine Samsung model. Again yet again, this filter will works just like the original. Most importantly, pure water quality is exactly the same – according to 3 NSF certifications.
Basically, the only difference between the generic and the genuine Samsung refrigerator water filter is that the former costs a lot less.

Aftermarket Filter Replacement (for EveryDrop Filter 4): Waterdrop WD-UKF8001 Refrigerator Water Filter
This time we can only provide you with one aftermarket filter, for the Everydrop Filter 4.
As a reminder: Filter 4 is used in bottom freezer and side-by-side refrigerators branded under Whirlpool, Maytag, KitchenAid, JennAir, and Amana. This also includes the Maytag UKF8001 refrigerator water filter!
As you might have guessed, it’s much cheaper than the OEM model due to factory selling, but the lower price is not without drawbacks.
Yes, you get 300 gallons filtration capacity which is 50% more than what the original filter provides. And 100% compatibility is guaranteed. On the downside, the coconut shell carbon block is only certified to reduce 8 different contaminants not 30.
Bottom line: This is a situation where we wouldn’t recommend going with the cheaper off-brand replacement refrigerator water filter, because filtration performance may lag behind – unless you only care about water taste rather than overall quality.
For GE
Please note: New GE refrigerators don’t allow you to use off-brand filters. That’s because GE fridge filters include an electronic chip.
The GE RPWFE refrigerator water filter is compatible with select GE french-door refrigerators, including those that use GE’s old RPWF filter.

Generic Filter Replacement: Waterdrop WDP-MWF
Let’s make this quick: Waterdrop’s WDP-MWF applies an identical filtration process to remove 14 different contaminants from water. This has earned the refrigerator water filter not 2 but 3 NSF/ANSI certifications: 42, 53, and 401.
The filter even beats the original when it comes to lead removal (99.6% vs. 99.3%).
Other than that, easy installation and functionality without leaks is a given.
Plus, the price tag is much lower obviously. We definitely recommend this generic water filter!
For Frigidaire
Frigidaire is another brand that recommends us to only use genuine water filters with their refrigerators to guarantee quality water filtration. Critics might say that the real reason behind that statement is that the company wants to sell as many replacement filters as possible, which come at a higher price than off-brand models.
To be honest, this is something we don’t really mind as long as there really is a difference in provided water purity. But is there?
There is indeed! During our research, we could only find one Frigidaire PureSource replacement filter for the ULTRAWF and the WF3CB, and this filter was only NSF 42 certified for chlorine removal. In contrast, genuine Frigidaire refrigerator water filters have at least 2 certifications and thus are guaranteed to not only remove chlorine but also asbestos, benzene, lead, mercury, lindane, BPA, and other harmful contaminants.
Simply put: Stick to the originals.
The EPTWFU01 is for french-door and side-by-side refrigerators by Frigidaire and Electrolux produced after 2015.

Above that, they’ve even earned more NSF certifications: 42, 53, AND 401.
Only the filter capacities vary a bit:
Overall, we recommend you go off-brand here. Why pay more for OEM filter versions when you get weaker performance?

OEM vs. off-brand, compatibility, NSF certifications – the following are things worth considering before you go out and buy the best fridge water filter. These are also the very same criteria we focused on when picking our top products for this guide.
OEM stands for “Original Equipment Manufacturer”. In other words, an OEM filter is manufactured and distributed by the same company that made the original refrigerator. For example:
Let’s say you own an LG refrigerator. The easiest way would be to buy a genuine replacement refrigerator water filter also from LG. But you don’t have to. You could also opt for a replacement solution provided by an off-brand manufacturer. In other words, aftermarket or off-brand refrigerator water filters are designed to fit certain refrigerator models made by another company.
On the upside, buying a filter imitation can save you quite a lot of money. Prices vary, but aftermarket filters are oftentimes 2, 3 or and even up to 4 times cheaper.
On the downside, the level of water quality you get might leave much to be desired. All that most of the really cheap filters do is reduce chlorine and other impurities to improve water aesthetics (taste and odor), but they won’t help to eliminate much of the harmful stuff, such as lead.
Bottom line: While trying to save money is a good habit, you should exercise caution when it comes to buying a replacement water filter for your refrigerator.
Another important criterion for choosing a refrigerator water filter is compatibility. If a filter is not compatible with your fridge, it won’t fit at all or at least not properly. The latter is a common cause for leaks.
Therefore, as your first step, you need to find your refrigerator’s model number. The number can be found in the owner’s manual and should also be printed on a label affixed to the refrigerator itself. Depending on the fridge type, the label can appear
This is what an example model number looks like: LFX28991ST
Once you’ve obtained the model number, you can match it to the list of refrigerators that a certain filter supports.
Pro tip: Use Amazon’s Partfinder to ensure compatibility. Simply enter your refrigerator model number into the search bar on top of a filter’s product description page.
Another way to go about this is to identify the old filter. A part number should be printed on a sticker affixed to its side. Then you can go looking for an identical replacement or a compatible substitute.
Depending on where you live, different kinds of contaminants may be present in your water supply. This is why, generally speaking, not every water filter is suitable for every household.
The safest way to ensure that the water you and your family consume is healthy is by sending a direct sample to a professional lab for analysis. Only by knowing what potentially harmful contaminants you’re facing, can you seek the ideal filtration solution. As an alternative, you can consult the latest Consumer Confidence Report of your local water utility.
What’s more, anyone could simply go online, import a random refrigerator filter from China, and sell it in the U.S. claiming it will remove fluoride, lead, pesticides, herbicides, asbestos etc. But only certifications from independent labs provide proof.
For refrigerator water filters, what you need to look for are NSF 42, NSF 53, and NSF 401 certifications.
In addition, there is NSF Standard 372 certifying lead-free material. Obviously, you want only lead-free material used in any water filtration system.
A filter’s capacity determines how many gallons of filtered water and ice it can provide before it requires replacement. For refrigerator water filters, the standard filtration capacity is 300 gallons. Some models may provide no more than 200 gallons, while others last for up to 400 gallons.
What we’ve noticed, however, is that filters which remove a wide range of contaminants oftentimes have a lower gallon rating. We assume that, due to the more thorough filtration process, the cartridges are prone to clogging. Thus, lower capacity isn’t necessarily a bad thing. Sure, you will need to change filters more frequently which adds to the costs, but you’ll also get better water quality.
Of course, you don’t need to worry about filter compatibility etc. if you simply install a universal inline water filter. This is also the best option in regards to contaminant reduction rates and filter life.
You only need to pay attention to design quality when opting for a generic water filter for your refrigerator. The best way to go about this it to check plenty of customer reviews, especially the bad ones.
There usually is no need to worry about difficulty of installation. OEM or off-brand, a compatible filter should fit your refrigerator with ease. The same goes for inline filters.
Last but not least, cost and warranty.
We’ve mentioned this before: You can save some cash buying an aftermarket refrigerator filter. Just don’t make the mistake and put your health at risk only to get a $10 discount.
As for warranty, most filters are warranted for lifetime for peace of mind.
More on Refrigerator Water Filters
A refrigerator water filter filters the water before it comes out of the water dispenser. And, in case your fridge features and ice maker, it also provides for crystal clear ice cubes.
Most refrigerator water filters are based on an activated carbon block. It’s most effective at removing chlorine and other chemicals, several heavy metals, and a bunch of other stuff.
The main advantage of using a refrigerator water filter is that it provides water of higher purity that also tastes and smells better. But, sophisticated filters aren’t cheap.
How and when to change a filter depends on your refrigerator model – anywhere from 2 to 6 months is possible.
One of the most common questions we get asked about refrigerator water filters is if they really work. The short answer is: Yes, refrigerator water filters do work. However, some are more effective at removing a wide range of contaminants than others.
Usually, refrigerator filters use activated carbon as their primary filter media. Activated carbon adsorbs impurities from water and traps them in its surface pores. Thereby, 2 factors determine the effectiveness of the filtration:
That’s why, generally speaking, large filters perform better than small ones.
A genuine fridge water filter improves the taste and smell of your drinking water.
Aside from improving water aesthetics, a fridge filter may remove contaminants that can be harmful to your health. Depending on the exact model, this includes lead and other heavy metals, pesticides, and all kind of organic contaminants.
A water filter saves you from buying water bottles. If you compare the costs, doing your own filtration is a lot cheaper.
200 to 400 gallons filtration capacity means you don’t need to change filter cartridges overly frequently which is convenient.
Chances are that thorough filtration reduces output water pressure.
Buying a water filtration system may be more affordable than buying water bottles. But, it’s still more expensive than drinking straight from them tap.
How to install or change a new refrigerator water filter depends on what type of filter your refrigerator uses.
If you’re having difficulties locating the water filter in your refrigerator, here’s where you can find it:
All in all, installing a water filter in almost any refrigerator is a piece of cake. In 95% of the cases, you don’t need tools, you don’t have to disconnect your fridge from the water supply, and you certainly don’t require any special training.
It’s simply a matter of removing the old filter by giving it a turn or pushing it in, and inserting the new cartridge in the same manner. Also, you can always consult the manufacturer’s instructions if you’re stuck. And don’t forget to flush the filter for a couple of gallons of water, also known as priming, before you start using the water.
You already know that refrigerator water filters rely on activated carbon for contaminant removal. These contaminants get trapped in the pores on the carbon surface. At some point, all pores will be filled and can’t absorb any more impurities. That’s when you need to change your filter at the latest. Of course, it makes much more sense to replace the cartridge some time before that to ensure you do not see a drop in water quality.
So, there’s no strict rule that says you have to replace a refrigerator water filter every 6 months or so. What refrigerator manufacturers do, however, is provide gallon ratings. These ratings are a rough guideline for how long a filter is going to last before it needs replacement. The standard gallon rating is 300. For some of you, 300 gallons may last for 4-5 months. For larger families, 300 gallons will only be enough for 2 months of filtered water.
Bottom line: How often you should change the water filter in your refrigerator depends on your water usage.
But not only that, it also depends on your feed water conditions. For instance, water with high mineral content a.k.a. hard water may cause a filter to clog quickly. As a consequence, water flow decreases dramatically to the point that it just takes too much time to wait for the water to be ready.
If you wait until you see a drop in flow or notice a change in how your water looks, smells or tastes, your family might have already been exposed to a number of dangerous substances. Luckily, there are better indicators that will tell you when it’s time to replace a fridge water filter.
In our opinion, the preferred brands for refrigerator water filters are the same brands that also manufacture the refrigerators themselves, namely: Samsung, LG, Frigidaire, Whirlpool, GE, Maytag, KitchenAid, JennAir, Amana, etc.
The only exception is Waterdrop, because it’s the only brand selling generic fridge water filters tested and certified to up to 3 different NSF standards for effective and broad contaminant removal (not just NSF 42 for chlorine taste & odor). In some cases, Waterdrop filters even beat the OEM competition in terms of overall contaminant removal, not to speak about the much lower cost.
