What is An Inline Water Filter?

An inline water filter is a machine designed to filter water. It becomes a part of a particular water supply. An alternative to an inline water filter is a dedicated water filter. The former is a better option since it doesn’t require the user to call a plumber or drill a hole in the sink.

What Are the Benefits of an Inline Water Filter?

As mentioned earlier, an inline water filter is beneficial and a better alternative than a dedicated water filter. Here are some of its pros:

  • Improves Water Flow: It improves the flow of water, which means you will not have to wait for long to get your glass filled. 
  • Environment Friendly: These filters can handle both low and high pressure conditions and do not affect the performance of other filters around them. 
  • Always Running: These filters are installed under the sink and will continue to work until you need to replace the unit. Since most are durable, you will not have to worry about replacement for a good few years.
  • Easy to Install: Inline water filters are typically DIY units that do not require special skills or tools for installation. Plus, they require little to no maintenance. 
  • Space-friendly: These filters can be concealed behind refrigerators or inside your cabinet. Moreover, most can be installed vertically or horizontally to save space.

How to Buy the Best Inline Water Filter for Ice Maker

We have highlighted ten of the best inline water filters for ice makers earlier in this article, yet it is important to know the right one for you. 

So, how to find the one most suitable for you? Pay attention to these factors:

Capacity

This factor will tell you how long the unit will last. We have covered some like the Watts Inline Water Filter 20,000 gallon Capacity- Inline Filter that can filter up to 30,000 gallons of water and is made to last for about 5 years, but there are some like the LASCO 37-1821 Ice Maker Inline Filter with 1/4-Inch Compression Connection, 2-Inch x 10-Inch that can only handle up to 2,500 gallons. 

Prices will differ based on capacity. Also, the capacity may depend on how much effort the filter has to put in. If the water is highly contaminated then the machine may not meet the required standards.

Filtration Capability

This is the most important factor because a filter will not be of much use if it cannot clean most contaminants. However, you may not always need the most powerful inlet water filter because not every household has highly unsafe tap water.

If the ice you get is cloudy then it may be due to the presence of chlorine. For such users, a basic option like the Whirlpool Ice Maker Water Filter – F2WC9I1 ICE2 may be enough. 

If you have highly contaminated water then it is best to opt for an option like the Filtrete Advanced Under Sink Quick Change Water Filtration System, Easy to Install, Reduces 0.5 Microns Sediment and Chlorine Taste & Odor, Includes 6 Month Filter (3US-PS01). Manufactured by 3M. 

Read the description to know what kind of elements a filter can handle. Go here to read about the types of contaminants found in drinking water. They are broken into classes depending on how dangerous they are. A filter that can remove class I contaminants is the best if your tap water is highly contaminated. Most cheap water filters can only remove class III contaminants.

Type of Filter

Some options above use a removable filter. These are kits that only require the filter to be replaced such as the Dupont, WFPF13003B, Filter System, 3/4 in NPT, 5 gpm. It is made to last a few months and once it is done, you can simply replace the filter. You will not have to replace the entire unit. 

On the other hand, there are options like the Woder WD-10K with JG-1/4 Ultra High Capacity Refrigerator Water Filter / Ice Maker Filter – WQA Certified – 3Y / 10K Gals – USA Made – With 1/4″ Built-in JG Fittings – For Unbraided ¼” PVC or 1/8” PEX that runs for a few months and need to be completely replaced.

Size and Installation

This factor is important because not everyone has a lot of space in their kitchens. It is best to go for a unit that is compact such as the Inline Water Filter Kit for Ice Makers. Moreover, the filter should be easy to install with the ability to connect in any position.

Others

Look for a water filter with certifications such as the NSF certified Omnipure K2533JJ Inline Water Filter with Quick-Connect. Such certifications prove that the product is reliable and can be used. Other than this, ensure it offers decent water flow – at least 0.5 GPM.

Best Inline Water Filters for Ice Makers: Conclusion
