In this article, we’re exploring the best refrigerator water filters. These filters can provide clean and pure water in your home for drinking and cooking needs, but some may be better for your fridge than others, as we’ve explained in our detailed refrigerator water filter reviews.
We’ve reviewed six of the top options on the market in our list. Our editor’s choice is the Samsung HAF-CIN/EXP, the best water filter for Samsung refrigerator. It features an excellent carbon block that removes 99% of potential contaminants to leave you water in much better condition, ready to drink! This filter has been tested and certified independently by NSF International, and you can really taste the difference. We’ve also collected five other options for you to view, in case you need a fridge water filter from another brand, for instance.
We’ve created our list of top aftermarket refrigerator water filters by reviewing a certain number of different criteria. The filter life is one of the key functions, and we’ve reviewed how long this is likely to last. We’ve also looked at the operating pressure the filter can work at, any certifications and which fridges it works within. The weight, and the number within the pack are also reviewed for each model. Our information has been presented as a simple overview table of the best options. We’ve also provided detailed reviews of each of the six models that have been selected, and a buying guide to help explain some of the terminology involved in water filters.
"It is best water filter for GE refrigerator but also works with Kenmore and Hotpoint models, features 99% removal of heavy metals, pesticides and herbicides, also removes over 95% of copper, Chromium and Cadmium."
"This budget friendly model improves the smell and the taste of water and can filter out 99% of contaminants including particulates Class I, Cysts, Heavy metals, Pesticides, Insecticides, BPA and more."
The Samsung HAF-CIN/EXP is a fantastic water filter for use within your Samsung fridge, but, as you would expect, it only works within a Samsung fridge. There is a useful tool on their website to help you to establish whether you have a fridge with a water dispenser that can take this filter.
It weighs just 8.8 Oz and it is pretty versatile other than needing to be used on a Samsung model. It can be used in 30-125 PSI pressures and temperatures between 34 and 100F.
The Half-Cin/EXP is designed to last either six months or filter 300 gallons of water (whichever comes first). This is a fairly respectable lifespan before you have to replace it, and it also means that the filter represents decent value for money. It has a filter light that tells you when the filter is ready to be replaced, too, so you don’t have to worry about reminding yourself when it is time.
The filter is effective, with multiple certifications. It filters out 99% of unwanted bodies from the water. It gets rid of Microbial Cysts, heavy metals and chlorine. This helps with both the taste and the quality and purity of the water. It can help you to avoid diseases as well as leave you with purer, more enjoyable water.
This is a great refrigerator water filter for use with Samsung fridges.
What do we love it for?
Filters 99% of unwanted material out.
Has a filter light to warn when it needs replacing.
More features: coconut carbon block for advanced filtration; comes in a pack of 3
The PURELINE PL-100 is the best water filter for GE refrigerator but also works with Kenmore and Hotpoint models. It is sold in packs of three and each of these can last 6 months each, so one purchase might mean you don’t have to worry about buying any water filters for your fridge for some time.
The filtration works excellently, it has a carbon block which makes use of coconut carbon. Though this is a generic aftermarket product. it is not made by GE, but it is excellent for use on their fridges but can also work with other brands. The carbon block has electro-kinetic absorption to allow for the product to filter more effectively.
The certifications include NSF, WQA, and IAPMO so you can rest assured that it has been independently tested. It has an effective, 99% removal of heavy metals, pesticides and herbicides. It also removes over 95% of copper, Chromium and Cadmium.
These aren’t cheaper than the branded models of water filter, but this isn’t a surprise because they are actually largely better than the models that ship with the fridges or are made by the same brand. The 0.18mm pore size is brilliant and makes the Pureline a strong choice.
The brand’s product listing page has a huge list of all the compatible models these filters are compatible with, so you can check before you buy.
More features: fits specific Frigidaire Side-by-Side models after 2009 that use a water filter located in the back, right top
Are you looking for the best inline refrigerator water filter that can work with your Frigidaire fridge? Some people have struggled to find specific models that were made after 2009, as many of these need a specific type of filter located in the top right of the fridge. The WF3CB works perfectly for these.
The filter life is six months or 200 gallons, whichever comes first.
We’ve named this as the best budget pick for refrigerator water filters. It is exceptionally affordable for those who have a Frigidaire model of fridge and who want to improve their filtration.
It improves the smell and the taste of water and can filter out 99% of contaminants including particulates Class I, Cysts, Heavy metals, Pesticides, Insecticides, BPA and more. You can make sure you vastly improve the purity of your water with no effort and not much expense!
This filter needs to be “primed”. This means you need to run over a gallon of water before using it properly.
On Amazon, you can check your fridge model to ensure that this actually fits your fridge so don’t end up wasting money. Be careful, as there is a very similar model that is just slightly longer that can be confused with this filter.
What do we love it for?
Effective for use in Frigidaire fridges.
Removes 99% of contaminants.
NSF 42, 53 & 401 Certified.
What were we disappointed with?
May need replacing more than every six months due to 200G capacity.
Best suited for: Whirlpool, Maytag, Amana, KitchenAid and JennAir
Operating pressure: 30-120 PSI
Certifications: NSF 401, 53, 42
Number in pack: 1
Weight: 7.2 oz
More features: reduces 24 contaminants including lead
Whirlpool is one of the best refrigerator water filter brands and the EveryDrop is designed for this brand of fridge, but can also be used for Amana, Maytag, Kitchen aid and other brands. There are multiple certifications including the vital NSF 401 to show just how well this filter manages to remove contaminants that you will not want in your water.
In total, it can reduce or totally remove up to 24 different types of contaminants and this includes lead, this has made the filter one of the best options if you live in an area where lead can be an issue in pipes.
As is pretty standard, this can be used for 6 months or 200 gallons of water, whichever comes first. This is the equivalent of about 1500 bottles of water.
This model can be used within different types of refrigerator. You can use Amazon’s tool to check if it is compatible with your Whirlpool fridge. It can be used in side-by-side, top freezer and bottom freezer models. It functions between 30 and 120 PSI.
This is usually one of the easier filters to install. Whirlpool models tend to be quite simple to install, but as it is compatible with lots of models, it does depend which you are installing it in.
More features: no tools or water-turnoff required to replace cartridge inside refrigerator; filters 50+ impurities
The GE RPWFE Refrigerator Water Filter has been named the best refrigerator water filter for GE systems. It is a simple model for installation and doesn’t need any tools. You can replace the cartridge within without having to turn off the water or use any tools. It really does take a few seconds.
It has a six month life before you have to replace the cartridge, but you will need to replace it if you use 300 gallons of water through the dispenser if you use more water.
It has a tested functionality to filter five different trace pharmaceuticals, so even tiny particles can be filtered out with this filter. It has over 50 different elements and contaminants in total that can be removed with ease. This includes chlorine-resistant cysts and heavy metals.
This filter can operate between 25 and 120 PSI.
Make sure you check that this is compatible. It’s easy to think that it will work in any GE fridge, but it has been designed with certain french door designs in mind. It is always worth triple checking so that you don’t waste your money.
This is quite pricey for what it is. Though it is very effective, you might not want to spend this month on six months worth of clean and pure water. Other systems might be more economical.
Why are we impressed?
Just the cartridge needs replacing and this can be done very quickly and easily.
This model is one of the best for LG fridges and certainly one of the best for improving the taste if you live in an area where chlorine has a big impact on the taste of your water. It can work its magic on a lot of different types of contaminant, but chlorine is the really noticeable difference when it comes to taste.
It uses modern filtration technology including carbon block filters which means very minute micron measurements of filtration. This leads to healthy and clean water and removal of dozens of different types of contaminants.
One negative is the fact that this does require you to run quite a bit of water through it before consumption to ‘break in’ the carbon filter.
As with all options, make sure you check the compatibility so you get a product that works with your fridge. This doesn’t automatically work with every LG model so refer to the manual to ensure yours is one that does take this filter.
This filter has an indicator, and when it reaches zero you will know that it is time to replace. This means you’ll never be using a spent filter. The actual replacement is pretty simple to do.
Why are we impressed?
Has an indicator for when the replacement of the filter is required.
NSF 42, 53 certifications.
What negatives must you be aware of?
Price is not the best.
Needs to be broken in by running water through, which is a bit of a frustration and wastes water.
Things to Consider
As well as providing you with the top options on the market for refrigerator water filters, we wanted to create a buying guide, too. We’ve included this guide to help you to be more confident, and make the right decisions when it comes to which water filter to buy. You can make a choice based on all of the available information, and our guide is designed to help you to understand what all the features and functionality of refrigerator water filters are. Some features might be more of a priority than others for you. Our refrigerator water filters reviews will go most of the way to help you to choose, but you should also think a lot about which of the features below are most important to you.
Why purchasing a refrigerator water filter will save your money in the future
What is the point in purchasing one of these filters, anyway? Well, for one thing, they can save you money in the long run. A water filter can make the water dispensed by your fridge far higher in quality and mean that you don’t have to buy water from the store. It can replace thousands of bottles of water, and in the process save you a lot of money.
It is also an alternative to having a water filter of some other kind, such as a filtration system installed in your kitchen, which can be very expensive! By having a water filter installed in your fridge, you may save money on other methods of filtration.
Also, the better quality of water means that you are less likely to contract diseases or become unwell as a result of consuming it. Let’s face it, you can’t put a price on your health, but ultimately, it is a good idea to buy a filter so that you don’t end up risking your health with poor quality water.
Features to consider while choosing a refrigerator water filter
The following features are the main ones we used when creating our reviews of refrigerator water filters. You should think about each of these features and which are the most important to you before you make your purchase. These criteria have been picked out as a way to compare and contrast the best filters, but compatibility could be a big deciding factor.
Replacement models/refrigerator models it’s compatible with
This is the first thing to check for. There is simply no point in buying a refrigerator water filter that doesn’t fit your model of fridge. Luckily, there are simple ways to check. Many of the manufacturer websites allow you to put the model of filter into a search box, or your model of fridge, and show the compatibility.
Don’t assume that just because the fridge brand is the same that it is going to fit. Some of the models will only fit within certain ranges. An LG fridge filter will not automatically fit in every LG fridge. Amazon also has its own method of helping you to work out compatibility. On the product page for many of the filters, you can enter the model of the fridge to check whether it will work.
Every model on our list has a filter life of six months. This is very normal, as more than six months for a filter can be hazardous, and the buildup of contaminants can cause issues with the water quality.
All of the filters also have a certain capacity in terms of gallons that needs to be adhered to. For instance, it may say six months or 200 gallons. This means once it has filtered 200 gallons of water, it is time for a replacement, even if it is a long time before the six month mark. Filtering a lot of water will age your filter far quicker, and it is better to be safe.
The water pressure needs to be within a certain level in order to work with your filter. The operating pressure simply tells you the pressure required in PSI. Most operate somewhere between 25 and 150 PSI which is pretty standard. The EveryDrop by Whirlpool Refrigerator Water Filter 1 works between 30 and 125 PSI.
There are many independent certifications that can be provided for water filters. NSF 401, 53, 42 are examples of these. The certifications are related to the type of contaminants and substances that are filtered out. These are managed independently, so the company offering the filter has to get it approved by an independent body. This means you can rest assured of the quality on offer when you see the certifications.
Always check whether this is in place for your water filter. It’s a nice vote of confidence and means you can feel a lot better about the quality of the filter, and the effect it has on the water. For more information, you can even look up the specifics of the certifications and what they mean.
What are the dimensions of the filter? Does it fit within the space for it in your fridge? This should be covered when you check the compatibility, but it is good to know the size and how much space it is going to take up. Also, if you plan to buy multiple filters together, you will need to know how much space you need to store them.
It’s important to consider the price of your filter, but it is also important that you consider the money that it will be saving you. Most water filters for fridges come in at under $50, and the best budget-friendly model is Frigidaire WF3CB. If you are able to save the cost of thousands of bottles of water (and the wasted plastic) then this is a fantastic way to spend your money.
Unfortunately, not many water filters come with any sort of warranty because they are a consumable product, designed for temporary use. It is very important that you buy from trusted sources as, believe it or not, there are fake products out there, too! These certainly won’t offer you any protection as a consumer.
How do they work?
How does a water filter work? Without getting too scientific, the water is pushed through a carbon block. This provides a sort of ‘netting’ effect. Imagine it like fish being caught in a net. Only the smallest particles in the water will get through the block, whereas the rest gets left behind and filtered out.
What additional features have been included? How have the manufacturers created a product that stands out? This is hard to do with a product such as a filter. It is either effective or it isn’t! However, some have worked on the filtration systems. Lower micron measurements mean smaller and smaller contaminants can be removed. This leads to a better quality and purity of water. Coconut shell carbon featured by PURELINE PL-100 is a popular substance for the actual carbon block, and this can help the filtration overall.
Some products offer extra features such as the ability to buy multiple filters in the same package. Others have functions including easy install and cartridge replacement.
This is a risky game. We do not recommend using a filter for longer than the six months that is usually advised. This can allow the built-up materials within to clog up and create more damaging bacteria that can get into the water supply. This defeats the object of having a filter in the first place. The six month limit is not set as a way for the filter companies to make money! It is to keep you safe.
Lots of contaminants are removed by these filters. For instance, heavy metals that are in the water. Lead, bacteria and chlorine (and chlorine derivatives) can all be filtered out. It depends on the micron size of the filter itself.
Some are manufactured in the USA, while others have been imported from China where they are manufactured.
The Samsung HAF-CIN/EXP is our editor’s choice, we’ve rated it 9.9. It can filter up to 300 gallons or last for six months and is easy to install within Samsung fridges. This model also comes with certifications and does a good job of removing nasty tastes from water.
Another of the best refrigerator water filters is the PURELINE PL-100. We’ve named it the best value as you receive three filters within a packet. They’re also versatile and can be used in many different fridges. We’ve given this model a rating of 9.8/10.
With a rating of 9.6, and the best budget choice, is the Frigidaire WF3CB. This works excellently on lead and heavy metals and fits easily within many Frigidaire fridges. Naturally, the best refrigerator water filter for you depends on the type of fridge you have in the first place. You need to choose a model that is compatible first and foremost.
