The Best Refrigerator Water Filters in 2024 Buyer’s Guide & Reviews
If you have a refrigerator with a built-in ice maker and water dispenser, you will know about the importance and high cost of water filtration. Refrigerator filters generally only need to be changed every 6 months, or after 200 to 300 gallons of water, but the price and quality of these filters varies a lot. Having said that, you need to make sure that you are getting the best refrigerator water filter, meaning one that will actually improve the quality of your water and at a reasonable cost.
Everything we recommend
We’ve thoroughly researched and sought out the best water filters for your refrigerator that have stood up to more scrutiny than others.
This filter is a replacement for the Everydrop Filter 4 for Whirlpool and other selected Maytag side-by-side refrigerators. WaterDrop is a Californain company and their filters use a renewable, activated coconut, carbon-block filter. Carbon block is a structure with immovable carbon particles that ensures more uniform and better filtration.
If your refrigerator doesn’t have an built-in water filter, then you can use an inline filter which sits between your refrigerator and your water source. For the most part, it’s not possible to bypass your refrigerator’s built-in filter unless it comes with a bypass plug. Culligan independently develops and largely manufactures their products locally in the US.
Purline is one of the most popular generic filter makers and they independently manufacture their own products, rather than simply rebranding and relabelling. Like most other filters, they use carbon block technology, but layered on top of this are two additional ionization processes to further extract solids and contaminants.
LG OEM water filters are some of the most expensive, so people often seek out cheaper alternatives. There are many generic brand alternatives with not much difference between them. We chose to go with WaterDrop because they are a trustworthy distributor, their products check out, and they have a professional and informative website.
EcoAqua is a Hong Kong based company and their replacement filters for Samsung DA29XXX series and HAF-CIN numbered filters are quite popular. Like many similar generic brands, they utilize carbonated coconut shell and carbon block technology. This ensures finer filtration and a more eco friendly product. Carbon block is a structure with immovable carbon particles that ensures more uniform and better filtration.

A Guide to Quality and Certified Refrigerator Water Filters
The first step is to check for official NSF product certifications that pertain to water filtration standards. Companies voluntarily submit product samples for NSF testing and verification. NSF 42, NSF 53 and NSF 401 are dealt with together as the core standard:
- NSF 42: This applies mostly to aesthetic effects such as “taste and color of your filtered water. It covers chlorine, taste and odor, chloramine, particulate, iron, manganese, zinc and total dissolved solids (TDS).”
- NSF 53: “This standard offers over 50 contaminant reduction claims.” Some of the most popular include: lead, cryptosporidium parasites,volatile organic compounds (VOC’s), and chromium.
- NSF 401: “This standard offers up to 15 specific contaminant reduction claims”, including prescription drugs, over-the-counter medications, herbicides, pesticides and chemical compounds.
- NSF 372 and 61: This certifies that the material and components and of your water filter are not contaminated with any dangerous levels of lead only.
You can browse here for NSF/ANSI 42 and 53 certified products and manufacturers, or do a search for any manufacturer, brand or product number.
As you can see, NSF 42 is the most basic certification for clean looking and good tasting water. Depending on your local water quality, this might be sufficient. For most urban or industrial centers, NSF 53 is recommended and additional NSF 401 is the safest option.
Is NSF Assurance Enough?
An NSF seal alone doesn’t verify the degree to which contaminants are reduced. Two products with the same NSF verifications could have vastly different filtration outcomes.
For further quality assurance you may want to look for the WQA—Water Quality Association —Gold Seal Product Certification Program. Their certification verifies safe construction materials, and that packaging claims are backed up by data.
Another third party certification often seen is IAPMO’s Water Systems Certification Program. Other assurity can come from independent lab test results sometimes audited by companies themselves.
Unfortunately, the independent Consumer Reports group, as of yet, do not test refrigerator water filters. You can, however, do your own inexpensive home water test, or you can evaluate ad hoc tests done people who have purchased the same product.

Generic vs Manufacturer OEM Brands
Although most people feel more secure with popular OEM manufacturer brands, some have the need to look for more affordable options. Almost all generic water filters are rebranded products. It’s important, therefore, to research the brand name distributor, their website, and what information is available on the parent manufacturer.
Many generic brand names carry NSF and WQA certification seals, but people have trouble finding them on search databases. This is because NSF certifications generally appear under the parent company manufacturer. In this case, you should search using the product model number. If the product is WQA certified, it’s easy to just use the brand name. Just because a product is packaged with a nice certification seal, doesn’t mean you should automatically trust it.
Researching Generic Brands: Asking the Hard Questions
Always read the claims manufacturers or distributors make about the product on their website, online store, and packaging. Make sure these claims match the certifications they carry, and that claims on the package match the claims made in their product promotions.
Although most products are backed up with at least one NSF certification and data sheet, other publicly available data sheets deemed trustworthy should also be fine. If a product carries more than one certification, that is all the better. We do not recommend products that don’t meet these basic criteria.
Check Points Before Choosing Your Refrigerator Filter Replacement:
- Although we do this for you, search the product for their NSF or WQA listing or any other data to back up product claims.
- Check to see if a data and installation sheet is available through the online vendor or website— these may often contain test results.
- Investigate the company website to see if they are more than just a fancy name, rebranded distributor. Make sure all claims check out.
- Check user reviews for the frequency of ‘leaks’ any ‘tests’ done.
- A no hassle money back guarantee is well worth having.
How to change a Whirlpool Refrigerator Water Filter
Refrigerator designs vary as much as water filter designs. Whirlpool is one of the most popular manufacturers, so if you have a Whirlpool side-by-side refrigerator, or a French door refrigerator, here is what to do:
Know Where Your Whirlpool Filter is Located
- Filter #1: Upper right-hand corner inside the refrigerator, or in some models, in the left side base grille near the floor.
- Filter #2: Upper right-hand corner inside the refrigerator roof.
- Filter #3: Left side of the base grille near the floor.
- Filter #4: Upper right-hand corner inside the refrigerator.
- Filter #5:Lower left corner of the base grille near the floor.
The standard filter replacement procedure is to first switch off your refrigerator water supply, and purge out the remaining water from the dispenser. Some water may come out when you remove the filter, so have a tea towel handy. After replacing your filter, turn the water supply back on, and usually you need to purge at least three to five gallons. Releasing air may gurgle and splatter, but that’s quite normal. It may take about 24 to 36 hours for the normal flow rate to return.
How to install Whirlpool FIlter #1
In the upper right hand corner you will clearly see the filter cover hatch. As you lift up the hatch, the filter will partly eject. Once the hatch is completely open, just pull the filter out. Take the protective cap off the new filter, and make sure the two O-rings are still aligned correctly on the two protrusions. Align the filter according to the arrow, and as you gently insert, the hatch will start to close. Push the hatch lid down to secure the filter, and it will snap closed.
How to install Whirlpool Filter #2
In the upper right hand corner of your French door refrigerator, you’ll see a roof filter hatch which you press to snap open. Twist the old filter to the left, or counter clockwise, to remove it. This filter has an oblong protrusion which looks like an arrow pointing upwards. When inserting the new filter, make sure this tapered end is facing up, aligned according to the arrow. As you gently insert it, it will actually self rotate into place, and you simply snap the hatch shut.
How to install Whirlpool Filter #3
You’ll find your filter below the door, in the grille, on the left hand side of your side-by-side refrigerator. Press the eject button on the side, and pull the filter out. Twist the filter cap counter clockwise to remove it from the old filter. Remove the protective cover from the front of the new filter, and make sure the O-rings are in place. Place the cap on the new filter aligned to the ridge, and twist clockwise until it snaps into place. Insert the new filter with the arrow aligned on the top, and push in until the eject button pops back out.
How to install Whirlpool FIlter #4
Locate the filter in the upper right hand corner of your French door refrigerator. There’s a tab on the underside of the hatch which you pull towards you, or push in if it’s facing you. Twist counter clockwise to remove the filter, and insert the new filter correctly aligned. Push and twist to the right until it clicks into place, then close the hatch and you’re done.
How to install Whirlpool FIlter #5
This is an older type of filter found in some side-by-side refrigerators. It’s located to the left of the base grille near the floor. Twist counter clockwise until the handle is in a vertical position, and pull out. You have to slide the handle cap off along the groove and place it onto the new filter. Make sure to remove the front cover and check if the O-rings are in place. Simply insert with the handle in a vertical position, and twist to the right until it’s horizontal.
Conclusion
Finding the best refrigerator replacement water filter is no easy task. They are mostly rebranded generic filters from a number of manufacturers based in China and Hong Kong. There’s not a lot of difference between them, so it’s better to go with a reputable distributor and one that also has a no hassle money back guarantee.
