Top-Quality Inline Water Filter For Ice Maker Reviews

1. EcoPure EPINL30 In-Line Refrigerator Filter

Smelly and unpleasant-tasting ice can make our favorite cocktails and summer drink less enjoyable. Using an inline ice maker water filtration system can help address such a concern. And one of the most trusted we have tested is the EPINL30 from EcoPure.

The top-rated attribute of the EPINL30 is its extra-long service life. Most of the water filters for refrigerator ice makers we have seen and tested on the market only come with a 12-month filter service life. Others may even have a shorter lifespan of 4 to 6 months. It guarantees better savings on your part in the cost of maintenance and replacement.

This EcoPure device is also effortless to install. It can be tricky at first. However, one only needs to follow the directions that EcoPure has included in the package. The design of the water filtration system allows it to be used for most brands of icemakers and refrigerators. However, we recommend checking with EcoPure about the compatibility of the EPINL30 with your icemaker brand and model.

It is comforting to know that EcoPure designs and fabricates all the components of the EPINL30 in the US. It is perfect for those wary about any item not made in the US. The most suitable part is that the ice that the EPINL30 never has an unpleasant taste and odor.

However, we lament that the EPINL30 cannot remove certain chemicals, including lead. It cannot also remove microbial cysts. If you are concerned about these compounds, then EcoPure’s ECODWF will be a better option. Another issue is the price. Average households may not be able to afford the system.

While the EcoPure EPINL30 does not remove certain unsafe compounds, it does work to give you fresher and cleaner ice to use in your drinks. Its extra-long service life makes the EPINL30 a great cost-saving system for modern families, too.

4. Culligan IC 1 EZ-Change Filtration System

Juices and cold beverages are more refreshing, with plenty of ice in the glass. However, it is also essential to ensure the quality of the water we turn into ice. It is where a water filtration system can be advantageous. And if you have an ice maker at home, you would want to install the Culligan IC-1 EZ-Change Inline Icemaker Filtration System. This device provides better-tasting and safer ice for your drinks.

The top-rated ice maker filter is part of Culligan’s array of inline water filtration systems for refrigerators and icemakers. We like the simple design and ease of installation of this system. This unit is not as complicated as the other icemaker inline water filters we have tested so far. You can have the system running in no time. The same is true during filter replacement. There is no need to call a professional as you can do it independently.

The filter only requires replacement once a year. It also guarantees a faster flow of water through your icemaker. Such a feature ensures you get all the ice for all your needs. Homeowners will also feel safer with the quality certifications that the IC-1 has.

One thing that we didn’t like about the IC-1 is its inability to remove sediments, cysts, lead, and other molecules such as VOCs, mercury, and MTBE. If you need more intensive water filtration, you will need Culligan’s other models, like the IC-3 and IC-4. Another issue that we find worrying is the quality of the construction of the filter cartridge. There is nothing wrong with the filter itself. The problem is that the bottom of the cartridge is quite easy to break.

Despite these setbacks, the Culligan IC-1 EZ-Change Basic Inline Icemaker and Refrigerator Filtration System is still a wise choice. It does provide you with ice that will not taste and smell like chlorine. It has an exceptional filter service life, too.

Independent ice machines are widely used in food and catering businesses. Expect restaurants, cafes, and bars to have one varying size but one that dispenses clean ice on-demand. Your very own refrigerator can also be equipped with an icemaker where with a push of a button, ice cubes are dispended instantly.

Business owners and household members, including you, turn to using water filters for ice makers because it promotes safe and pure water ready for instant use. It doesn’t matter if the ice will be used – beverage, desserts, or just a cooling agent because with water filters, you are guaranteed cleaner, safer, and better-tasting ice. Refrigerated water filters for ice makers usually use granular activated carbon, which has an average scoring of 20 microns.

A water filter for an ice maker is pretty much geared toward removing the impurities found in tap water. These are harmful contaminants that negatively affect the overall quality of water in taste and smell. It provides clean and pure-looking ice cubes that we want to have for the most useful of our well-being.

Most refrigerators today come with built-in water or inline filters where your water and ice dispenser flow through and get cleaned during the process. There are various layers and filtering agents being used to help clean the water. It can be carbon filters, phosphate filters, sediment filters, and so much more.

How Does It Work


An ice maker’s built-in water filter works by its easy snap-in and out option and has activated carbon components either as a carbon box or in granulated form. This layer removes the taste and odor that’s not good. It also reduces volatile organic compounds and other sediments that cannot be seen in the naked eye.

Aside from activated carbon, an in line water filter for refrigerator ice maker would also have phosphate that is in charge of hard minerals becoming deposits. These filters are also utilized to prevent corrosion on metal and water-touching parts where rust will form. It will do this by creating a creative coating that is against chlorine, acidity, and others that generally result in corrosion and rust.

Depending on the brand and model of your choice, there can be more stages or processes involved. Still, the bottom line, the water filter works in collaboration with the different filter labels to remove all possible dirt and contaminants from your water before your first sip. It ensures that even before your water turns into ice cubes or whatever form, it is already up to 99% free of the harmful elements in the water. Then with a push of a button or a twist of a knob, comes out a tray or cartridge full of ice that is safe, accessible, and clean for whatever you find it fit for use.

Once it has reached its capacity of water to be filtered, all you need to do is to replace the filter correctly, and you are again set for another batch of ice water in just a matter of time.

Advantages And Disadvantages Of Using A Water Filter For Ice Maker

Without a water filtration system, regardless if it is pre-filters, the tap water, before it flows to the ice machine or one that is built into the actual ice machine, may sooner or later experience some issues. It is due to the presence of contaminants in tap water.

The main advantage of having a water filter for ice makers and an even better one built into the machine can address limescale. Limescale is the biggest threat to any device that uses or is exposed to water.

It not only unsettles the overall capacity of the ice maker machine, but it can also pave the way for bacteria buildup. The sediments in tap water can result in clogging the whole system, especially the valves and the tubes.

It will eventually stop working, costing you more for parts replacement or even the entire appliance itself.

Another advantage is it help improve the overall quality of the ice that it makes. A filter removes the impurities and contaminants in water, and the objective is to produce clean, safe, and better-tasting water that is ready for consumption.

Repair and maintenance would cost you more too. Another one is if the refrigerator ice maker filter, for instance, is incorporated in your refrigerator, then expects lesser space for storage.

Do I need a water filter for my ice maker?

However, if you want your machine to make the top-rated possible ice for your drinks, then you will need a water filter.

Where is the filter for my ice maker?

The most suitable way to determine the location of the water filter for your ice maker is by checking the information in your owner’s manual. Ice maker manufacturers place their water filtration systems in different locations. This is true for those with a built-in water filtration system.

If you do not have the manual, you can log into the official website of the manufacturer of your ice maker. Many companies have a Service section where consumers can download useful files as manuals. An alternative will be to search the information online through a general search.

Check the body of your ice maker for a knob or a similar fixture. It will allow you to open a panel and access the component inside. In most cases, this panel will house the water filter assembly. There are some models of ice makers that have their water filter compartments located near the control interface of the ice maker. Some brands have a water filter located at the back. It is why it is essential to check the whole body of the ice maker so that you can identify the location of a panel.

If your ice maker does not have a built-in water filter, then there is no point in looking for it.

How do you install an inline ice maker filter?

The basic design of a filter calls for connecting one end of the device to the water supply line and the other end to the water line that goes to the ice-making mechanism of the ice maker. This is true for both ice makers with built-in and non-built-in water filtration systems. They will only differ in how you install the inline ice maker filter.

If your ice maker has a built-in water filtration system, you will need to access the water filter first. Start by opening a panel to access the water filter. Check your manual about the location of this compartment. Make sure to close the water supply to your ice maker before installing a water filter. Once opened, you can then remove the existing water filter. Many products come with an easy twist off design. It allows for easier removal of the cartridge that houses the filter. Replace the filter with a new one and put the cartridge back. Secure the filter and close the compartment.

If you have an ice maker that does not have a built-in water filter, installing a filter can take more time. Do not forget to close the water supply to the machine. Check the water filter manufacturer’s directions for installing their product. Most products will require cutting the water line to accommodate the length of the water filter cartridge. Once cut to its recommended length, attach the different hardware onto the opposite ends of the cut waterline.

Connect one end of the waterline to one side of the water filter. Connect the other end of the waterline to the other side of the water filter. You now have installed the water filter in your ice maker.

Make sure to prime the filter by allowing water to run through it. Recheck the manual as to the volume of water with which you need to prime the filter.

How to know when it is time for an ice maker filter replacement?

It is time to replace the water filter for an ice maker and refrigerator filtration system when the built-in “filter change” indicator light turns on. Many ice machine manufacturers have integrated filter replacement reminders to keep the system running optimally.

If your ice maker does not have this feature, you can check the home water filter’s manual for the unit’s capacity (e.g., 2,000 gallons). Sadly, it would be nearly impossible to determine how many gallons of water you have already turned into ice, unless you keep track of usage every day.

The good news is that manufacturers of ice maker water filters also provide a time estimate of the filter’s lifespan (e.g., nine or twelve months). You only need to determine the last time you changed the inline ice maker filter kit to know when to replace it.

Alternatively, you can check your appliance’s ice production. Ice maker filters can clog because of impurities buildup. Sediments and other particles can obstruct the pores in an inline water filter for the sink, reducing water flow. Hence, your machine cannot produce as much ice as it should.

What does a standard inline ice maker filter remove?

A standard inline ice maker filter is similar to any inline carbon water filter. Carbon filtration removes tiny particles in the water that can make ice cubes look hazy or cloudy instead of crystal clear.

The water filter also removes chlorine, including its uncanny taste and scent, to transform ice cubes into sparkling crystals that will not add an unpleasant taste to drinks.

Other types of inline water filters for ice makers can remove pesticides, volatile organic compounds, pesticides, herbicides, heavy metals, and bacterial cysts (i.e., Giardia and Cryptosporidium).

Which inline ice maker filter removes the most toxins?

Culligan’s IC-EZ-4 EZ-Change Inline Filtration System is one of the most efficient ice maker filters for removing toxins. It can reduce all toxins identified under the NSF/ANSI 42 and NSF/ANSI 53 standards by as much as 99.99%. Unsurprisingly, it is a favorite for RV owners and homeowners alike.

On the other hand, the most effective inline water filter for removing impurities is a reverse osmosis system. This water purification technology reduces many harmful substances not eliminated by other filtration systems.

While ordinary carbon filters for well water systems have a 0.5 t0 50- micron pore size, RO membranes have microscopic holes that are 0.0001 microns in diameter. These semi-permeable layers only allow water molecules to pass.

Unsurprisingly, RO inline ice maker filter systems are the top-tier in eliminating the most toxins and other harmful substances.

How long does an inline ice maker filter last?

The lifespan of an inline ice maker filter is similar to the longevity of a conventional inline filter for drinking water, which is about three to six months.

However, different filtration technologies have varying lifespans. For instance, carbon filters can last 18 to 24 months, while an RO membrane can last two to four years. On the other hand, ultrafiltration membranes can last three to seven years.

Water quality and consumption can also impact an ice maker filter’s longevity. The more frequently you make ice and the more impurities in the water, the shorter the filter’s lifespan.

How to care & clean?

Water filters do not require frequent cleaning unless you have a cleanable and reusable water filter in your system. Such devices allow you to remove the water filter and clean them. You can then put them back into the cartridge to continue with their work of filtering water. In case of uncertainty, it is most useful to consult the manual.

Cleaning a water filter for an ice maker requires its removal from its connections. Close the water supply line and remove the filter from its housing or cartridge. If your filter has netting on the outside, it is most suitable to remove this, too. Hose the water filter down to remove the gunk that may have accumulated.

Make a solution of oxalic acid by dissolving about 62.5 grams of oxalic acid powder in a gallon of water. Mix well and soak the pleated water filter in the oxalic acid solution for 20 minutes. If you have a carbon filter, then a bleach solution is better. Mix one gallon of water and a tablespoon of ordinary household bleach. Soak the carbon water filter for 10 minutes. Make sure to rinse the water filter very thoroughly right after soaking them in either oxalic acid or bleach solution.

You also need to clean the cartridge or the housing of the filter. Fill a cup with half an ounce of bleach. Add water to fill the bowl full. Pour this solution into the housing of a pleated water filter. For carbon water filters, replace the paper and secure it as tightly as possible. You can then reinsert the filter into its housing.
