Almost 70% of ice machine service calls are due to water-related problems. As the water freezes, minerals dissolve and form scale on machine components. Over time, it leads to serious problems with ice machines. Using proper ice machine water filters improves quality and flavor. It removes chlorine and various contaminants, making the water softer and cleaner.
However, choosing the proper filter can be a bit tricky. In this article we’ll show you the top 11 choices in the market.
Ice Machine Water Filters
When your machine makes ice cubes, their quality is directly correlated with water. If the water is pure and clean, the cubes will be too. On the other hand, if the water is contaminated, cubes can develop an unpleasant odor and bad taste. If that’s the case with your ice machine, you need to buy a filter.
Besides purifying the water, an ice machine filter may extend the life of your appliance. If your water is contaminated, it will build scale and negatively affect all of the machine parts.
Ice Filtration
Ice machine water filters clear the water before it even reaches the maker. They also manage and treat hard water, which can leave dust on top of cubes, and build scale that damages the equipment and inner parts of ice makers.
Chlorine Removal
Chlorine in water gives it a specific taste and smell, which further affects the ice quality. If you put that ice in your drink, it may give it a “swimming pool” smell and taste as it melts down. Filters can remove this contaminant, leaving you with better water quality.

Choosing the Right Water Filter for Your Machine
Consider Water Condition
When buying an ice machine water filter, the first thing to consider is the water condition. Not every filter is ideal for all situations. How do you know what the condition of your water is?
For example, states like Arizona are known for high mineral content in their water. On the other hand, some states are known to have a much lower concentration of particles. Also, some states have hard water in general, and hard water can damage your appliance.
If you want precise results, call a professional to test your water. Once you know the condition of your water, you can properly choose the best water filter for your needs.
Consider the Flow Rate
What is flow rate and why does it matter? Flow rate is the amount of water that can pass through the filter without causing any damage. For example, if your filter has a 3 GPM rate, it means that 3 gallons can pass through the filter each minute.
Of course, you should look for the rate according to your ice machine. If the maker requires a higher rate, and you install a small filter, it can lead to some problems. For example, ice cubes might be too small, or it could even damage the appliance over time.
Water Filter System’s Rated Capacity
Rated capacity should be greater than the amount of water that your machine will use between filter changes. You will want to calculate that amount first and then check for the rated capacity of the filter.
The Durability of the Filter
Filters are disposable, which means that you will have to replace them from time to time. After you install the filter, it’s always on. It will work until you need to replace it, which is usually after 500 gallons. However, depending on the unit, it might last longer.
Cost of the Filter
The cost of the ice maker filter differs from unit to unit. Remember, the most expensive product isn’t always the best. You need to replace your filter every six months or so, which can be very pricey if you choose a more expensive filter. You should always look for a compromise between the price and the quality.
Types of Water Filters for Ice Machines
All of these filters can be divided into three categories. They differ by the particles that they can filter, so knowing your water condition is crucial.
Sediment Filters
These filters are standard and most widely used. You can find them on almost any machine. They are good for preventing larger particles from entering the water. However, they are not ideal for removing small particles or chlorine.
When buying a sediment filter, you should have two things in mind – micron rating and flow rate.
Micron rating tells you the size of particles that the filter will block. For example, if the micron rating is 5 microns, the filter will successfully prevent 10-micron particles from entering the water. However, particles smaller than five microns won’t be affected. Flow rate is also important to prevent damage to your appliance.
Phosphate Filters
If you live in a city where water has lots of minerals, you might have had problems with scale. It happens when minerals like magnesium and calcium bind together, which can become a serious problem for your machine over time.
If you have problems with scale, using a phosphate filter is the way to go. However, just like sediment filters, you should replace phosphate filters every few months.
Carbon Filters
Carbon filtration is a very old method of filtering water. It dates back to ancient Egypt when people stored water in charcoal pots. They noticed that after a short time, the water taste becomes significantly better.
Those filters use a process called adsorption, where the specific texture of activated carbon traps particles from entering the ice maker. However, unlike the previous two types, carbon filters also trap chlorine.
Like most filters, you should replace them every six months.
Installation
Installing this kind of water filter is usually very simple. You don’t need any DIY skills or special tools. Depending on the filter, you will need a wrench, pipe cutter, drill, screwdriver, rag, and some screws and nuts.
First, turn off the main water supply. Then, properly mark the best position to drill screws that keep the filter on the cabinet, wall, or wherever you’re placing it. After marking, drill the necessary holes and attach the filter.
Next, remove the inlet pipe using the wrench and attach the inlet pipe of the water filter to the valve. After that, attach the water filter to the water tap, but keep a bucket ready for possible leakage. It might happen while tightening the nuts. Also, it’s useful to have a rag nearby, in case things get a bit dirty.
When you complete the whole connection, you can turn on the valve. It will let the water pass through the filter, so let it flow for at least half an hour. After that, the filter will be ready for normal use.
