Buying Guide for Inline Water Filter For Ice maker

Below we have designed special inline water filters buying guides so that you will find it easier to choose the right one.

The markets are flooded with hundreds of models, but you need to make sure you are buying the filter best suited to your needs.

Let us have a look at the major things to consider before buying an inline water filter.


The first thing you need to understand is the purpose of buying an inline water filter.

Remember! Inline filters are specifically designed to connect to your main plumbing line, which is why they cannot be shut down.

This makes it essential for you to take the responsibility to keep a check on the maintenance and replacement of the filter. Otherwise, things will go nasty. 

Research Thoroughly 

The most important thing to start off the journey to find the best filter is to up your research game.

You can choose one of the two recommended ways. However, it is preferable to try out both for refined research.


Try to look out for the right thing by yourself because no one can understand your needs better than yourself. Surf the internet and search for the top-selling brands and products that fit your requirements. You can also visit the market to have a close look at how these filters look.

Tip! Compare both online and market rates to make a decision.


If you are always busy, you won’t want to get stuck in the research for the best quality filter. However, you will still want the best.

In such cases, you can ask your trusted acquaintances, friends, and relatives to help you out. Ask them about their experience with the inline filters they are using. It is always a good idea to buy the product people are already using and have good remarks about it.

Type of Inline Filter You Need

Another important thing to consider before buying an inline water filter for the ice maker is the type you need. There are basically different types of inline filters that you can choose from.

They are:

  • Utility coalescing 
  • High- Efficiency Coalescing 
  • Activated carbon
  • 2 in 1 filter

The utility-grade coalescing filtration removes all the particles from the water with the help of a size 1 micron. These filters are often used as pre-filters to other water filters as well.

The high-efficiency filters use a 0.01-micron size to remove bad taste, odor and other particles from the water to stop the cloudiness in your ice.

Activated carbon inline filters are efficient in removing mist and vapors along with other contaminants and particulates from the water.

While the two-in-one filter absorbs and removes chlorine, bad taste, odor, and small particles. Mostly, activated carbon filter and 2 in 1 filters are used for residential needs. 

Major Features

The following are some of the major features you should keep in mind before finalizing your inline water filter. 


Your inline filter can be resistant to withstand both high and low temperatures but perform incredibly well in high-temperatures.

Important! Low-temperatures can lower down the performance level as your ice maker will not be used as much as in high-temperature

Should Always Be On

This is one thing that you need to care for. Although inline water filters do not require any maintenance, they should always remain on. If your water filter keeps on shutting down, it can be a problem. 


Inline water filters are usually designed to be concealed behind your cabinets or under the sink. So, make sure that you get yourself a compact inline filter to stay away from any hassle.

Installation & Maintenance 

Inline water filters are directly installed with your plumbing line, which is why the installation should not be stressful for you. Similar to installation, the replacement of the filter is another thing that you need to consider before buying.

Important Point! Try to buy a filter that you can replace by yourself. 


The price of the product you are choosing makes a lot of difference in quality and durability.

This is a fact that most of the inline water filters are cost-friendly. They don’t go beyond the range of $10-$30.

However, if you are struggling with the bargain of a costly water filter, make sure that its functions, filter capacity, and life are as advanced as its price.

Tip For You! Don’t go for too cheap filters because they will remove just a few contaminants. 

Filter Life

You need a filter that can go at least 6 months without any replacement. Obviously, in today’s busy world no one has time to keep a regular check on the filters.

If you are buying an inline filter with a 3-month filtration life, make sure that you keep a reminder for the replacement. Otherwise, your water will taste very foul. 

Filter Capacity

The capacity of the filter depends on the flow rate and water pressure altogether. It is better is the psi of the water filter is at least 25 and the flow rate is 0.5GPM.

The filtration capacity of the inline water filter should be at least 1500 gallons so that you can easily get great tasting water and ice whenever you need it.


  • What Are Inline Filters?

Inline filters are water filters used to clean and purify the water of your water appliances such as refrigerators, water coolers, dispensers, ice makers, and coffee makers. These filters are directly connected to your water supply to provide you with contaminant-free tasty and healthy water. They are easy to install, compact in size, and designed to last long.

  • How Do Inline Filters Work?

By far you know that an inline filter is directly attached to your waterline or on the appliance so that clean water runs down the appliance as soon as it is turned on. Different models of inline filters work differently, but the general procedure is almost the same.

The water reaches the pre-sediment filter as soon as it reaches in the system where all the dirt, rust, dust, sand, and other debris are removed. After that, the water reaches to the activated carbon level where all the contaminants are removed.

The process that the filter uses to attract the contaminants is called adsorption. Then comes the mineral filter where the additional minerals like chlorine, copper, and zinc are removed.

Once the pre-filtration process is completed, the water reaches the post-filtration level. Only a few small particles are left in the water when it reaches in the post-filter where the polishing will be done.

The post-filter is a mesh-like filter that filters out the last small particles from the water. Through this mesh, the clean and purified water reaches your faucet. 

  • How to know when it is time for a filter replacement?

Your filter replacement time depends on the quality of your tap water. Of you are using municipal water; your filter can easily stay as long as its actual life. On the other hand, well water can force your filter to use its capacity more than usual. This can make its life a bit shorter.

  • What does a standard inline filter remove?

A standard inline filter that is compatible with the major refrigerator brands removes chlorine, sediments, bad taste, and odor. 

  • How to buy an advanced inline filter in a limited budget?

You don’t really have to buy an advanced level inline water filter if you don’t have a budget for it. a filter with mediocre features works as fine as any other filter. 

  • Do Inline filters remove TDs?

No, there are a few inline filters available in the market that removes TDs as well as other contaminants. 

Final Words
