Not only is the appliance an excellent source of safe and refreshing water, but it’s also a cost and energy-efficient option for the discerning buyer. By eliminating the need for water bottles, these filters also help to declutter your house.

Primarily, water filters function by removing contaminants such as chlorine, chromium, dust particles, and pesticides. Consequently, any bad odor or taste is also removed, but inline filters are a step ahead. They work along with ice makers to yield ice that is healthy and tastes great.

However, the market is teeming with inline water filters, each with its unique properties and advantages. Therefore, choosing the right one for your needs may be difficult. This is why we’ve compiled a list of the 11 best models out there and followed it up with a brief buyers’ guide.

So, let’s get started, shall we?

Why Did We Like It?

This excellent filter from EcoPure is one of our personal favorites and for all the right reasons. Its exceptional filtration capacity aside, the appliance scores high on a number of other points, with design being the first. Manufactured entirely in the US, it is designed to effectively remove sediments as well as chlorine, while also acting on unpleasant tastes and odors.

Furthermore, the filter is easy to install. Equipped with both ¼ compression and push-to-connect fittings for copper or plastic water lines, it proves to be a hassle-free appliance that requires little maintenance and no special technical skills. 

Last but not the least, this nifty piece of equipment comes with the promise to last 5 years of use. Dependable and versatile, it is compatible with all major brands of refrigerators such as Samsung, Whirlpool, Kenmore, Frigidaire, and GE, and offers incredible value for money.

What Could Have Been Better?

The only cause for complaint users may have with this otherwise promising appliance is that it does little to remove unpleasant tastes in the water. However, while this is certainly something EcoPure could work on, it isn’t a deal-breaker by far, and the features on offer are extremely attractive.


  • Easy to install
  • Good value for money
  • Requires little maintenance


  • Doesn’t remove unpleasant taste


The GE GXRTDR is the ideal inline water filter if a high degree of hassle-free functioning is your primary lookout. It’s also a great fit for those who like their water to not only be safe but also taste exceptionally good. Easy to install and operate, this model is well worth your time and consideration.

As far as durability is concerned, the GE GXRTDR is a winning option that delivers well. It fits most refrigerator models and is designed to extend their lifespans considerably. Also, the appliance comes with a part finder query box that allows you to determine whether it’s compatible with your fridge or not.

Another feature that impressed us the most was its capacity for filtering chlorine. You must be wondering what’s so novel about that, all water filters do it. But the GE GXRTDR is exceptionally adept at removing chlorine from the water including its smell. The result is safe drinking water that also tastes great. 

Last but not the least, the device is durable and comes with quick-connect fittings that allow for ease of installation. Therefore, attaching it to your fridge’s water lines becomes a cakewalk, and given the filter’s affordability, it only enhances its appeal.

What Could Have Been Better?

Although extremely convenient, the quick-connect fittings are sometimes prone to breakage while screwing them in as they’re made out of plastic. Barring this, the filter has no functional flaws and makes for a great budget solution to water filtration issues.


  • Impressive chlorine filtration capacity
  • Removes all odors
  • Easy to install
  • Highly compatible and easy to install
  • Good value for money

The quick-connect fittings go a long way in enabling this; they work on simple twists and turns.

In terms of filtration, this is an efficient model that removes most contaminants with ease, especially chlorine. Alongside this, it also deals with bad smells and tastes with the resultant water being refreshing and healthy.

Lastly, the device is made of premium quality materials and comes with an impressive lifeline. It filters up to 3000 gallons of water in a single cartridge and the other option is to use a single cartridge continually for 12 months before replacement. All things considered, certainly a strong recommendation from us.

What Could Have Been Better?

The only aspect that users may be concerned about is the size. Culligan’s filter is of considerable proportions and takes up space behind the fridge. The best way to avoid issues of space is to ensure that there is ample free area available for the filter before you buy it.


  • User-friendly device
  • Cartridges are easy to replace
  • High operational efficiency
  • Durable and long-lasting


  • Takes up a lot of space

There’s no need for specialized tools or technical knowledge when it comes to set up and the added push fittings streamline the process further.

What Could Have Been Better?

While there are no functional flaws with the appliance, users should take care while installing it as the direction of the water flow is not marked. In that case, one may end up attaching the filter backward which then hampers its performance and also leads to unnecessary trouble.


  • Budget-friendly option
  • Easy to operate
  • Tasty and safe drinking water
  • Push fittings for enhanced functioning


  • Direction of water flow not marked

5. AQUACREST GXRTQR Refrigerator Water Filter

It filters up to 2000 gallons in a single lifetime and also comes with a spare cartridge that does away with the additional expense of buying a new one for replacement. 

Lastly, we can’t stress its affordability enough. Equipped with a dependable mechanism, Aquacrest’s unit ensures the user gets only the best of the best without incurring a heavy expense. Needless to say, it is one of the best models in its price range and makes for an attractive bargain.

What Could Have Been Better?

Aquacrest’s appliance is close to perfect but it’s not entirely flawless. The area that we felt needed some work was the cartridge replacement process which can be cumbersome and time-consuming. However, the company has a responsible and hands-on customer care team and such issues are easily resolved.


  • Filters up to 2000 gallons
  • Budget-friendly
  • Includes a replacement filter


  • Cartridge replacement could improve

6. Watts Inline Water Filter

In addition to its compatibility with a remarkable range of refrigerators, the filter also works with ice makers, water fountains, and coolers among others. Now that’s stunning, isn’t it?

In terms of filtration, it’s equally effective. Making use of the KDF fluid treatment in its mechanism, it is capable of filtering a whopping 20,000 gallons of water before the cartridge needs to be replaced, which is 2 years. The mix of zinc and copper in the treatment eliminates the possibility of contamination from chemicals and offers clean drinking water that is also good to taste. 

Last but not the least, installation is simple and takes mere minutes. Also, for such a versatile and high-functioning device, Watts’ filter is low maintenance and, on all accounts, makes an offer that is hard to refuse.

What Could Have Been Better?

Although nearly free of technical faults, this excellent water filter requires a thorough checkup every 6 months to ensure the proper functioning of the cartridge. However, we feel this is a minor compromise to make in return for such a capable appliance that wins on all other fronts.


  • High operational efficiency
  • Versatile device
  • Works well with water supply pipes
  • Sophisticated filtration mechanism


  • Requires an informal review every 6 months

7. Lasco 37-1821 Ice Maker Inline Filter

This inline water filter from Lasco tackles contaminants in a fashion that leaves little to be desired. In doing so, it employs charcoal filtration which is highly effective in filtering minute toxic particles. Also, this greatly improves the taste and smell of the water which is then ready and refreshing to drink.

With Lasco’s filter, installation is quick and free of hassles. The connection fittings are a nifty 1/4th of an inch long while the unit itself is 2x10 inches in dimension. Furthermore, it can be fitted either horizontally or in a vertical position and fits easily behind refrigerators of a variety of makes. 

Last but not the least, users need not unnecessarily spend money or time replacing this filter. Once a year is adequate for cleaning and the device also comes with a 1-year warranty. All things considered, this budget-friendly option from a trustworthy brand is worth your consideration.

What Could Have Been Better?

This otherwise excellent filter falters in two places, however, neither is a dealbreaker in any way. One, it requires a long flush period before you can start using it for the filtration to be 100% effective. And two, although no toolkit is necessary, replacing the appliance can be a time-consuming affair.


  • Easy installation
  • Very effective filtration
  • Good value for money

Why Did We Like It?

Although the filtration capacity of this model is beyond commendable, what truly takes the cake is the simple installation and negligible maintenance. Culligan’s filter comes with connector fittings that can be screwed on and off with ease without requiring any specialized skills or tools. Furthermore, it saves you time on the setup process and makes a rather attractive bargain on that front.

In terms of filtration, it is effective in significantly reducing the levels of lead, atrazine, cryptosporidium, giardia, lindane, and other class I particles having similar properties. Also, the taste and odor of chlorine are also taken care of. On the whole, the water passed through this filter comes out clean and safe to drink and is also very refreshing. 

Lastly, its 3000-gallon capacity makes the filter well-suited not only for home use but also for campers, boats, and RV vans. Cartridges are easy to replace but can function without a hitch for 6 months or 500 gallons easily. Like we said, setting up this filter does not take time, and neither does the replacement process.

What Could Have Been Better?

We went over the appliance with a critical eye but couldn’t find a single functional flaw. The only grievance users may have is with the replacement period as for some, 6 months might be too soon and expensive. However, it is a small bargain to make for such a functional device and by no means a dealbreaker.


  • Extremely simple installation
  • Effective filtration of toxins
  • Removes odor and unpleasant taste


  • Replacement period could be longer

In addition to removing common contaminants from the water, it also does its bit to eliminate parasitic cysts such as turbidity, atrazine, and cryptosporidium. Also, the taste and smell of chlorine is greatly diminished as are sediments.

The feature that really caught our attention was the filter media. Unique in function, it is electrostatically charged and acts, in essence, as a small magnet. In turn, the most microscopic particles, ones that are often missed by other filters, are filtered along with the larger contaminants. 

Last but not the least, the filter is easy to install, and what’s more, it attaches directly to the tap. The process takes around 30 minutes and once connected, proves to be an extremely convenient household appliance to keep handy. All in all, this is a filter you can bet on without a second thought.

What Could Have Been Better?

The only grievance we had with this otherwise excellent option is the replacement period. At 6 months, it is a considerably smaller window than most other products in the market and may prove to be expensive. However, by no means and especially given the filter’s features, is it a deal-breaker!


  • Enhanced filtration techniques
  • Convenient to use
  • Durable and trustworthy

The purification process is strengthened by passing the water through four filtration media, no less! The result is cool water that is ready to drink and exceptionally invigorating.

In addition to that, water from this filter is bound to taste great. This is because while it gets rid of chlorine and fluoride, the filter ensures that the minerals already existing in the water remain present.

Last but not the least, this model is among the easiest to install. Time-efficient and hassle-free, all the accessories required for setup are included in the package and you need not spend an extra buck for them. In this way, it saves you money and becomes a cost-efficient option as well.

What Could Have Been Better?

The CuZn ILFC-200 is slightly heavier than its counterparts and thus, difficult to handle. However, while this may be a slight inconvenience for users, considering all that’s on offer, it is a small compromise to make.

  • Retains taste and health of water
  • Easy to install

What Could Have Been Better?

Inline Filter Buyers’ Guide 

It must be evident from our list that there’s no dearth of inline water filters in the market and each has something unique to offer. Be it technology or cost-efficiency, every model comes with its own advantage.

This is precisely why users may have trouble selecting the best one; all of them make excellent offers. However, there are some specific points that you must consider before making a purchase, and they’re outlined below.

Filtration Rate

While the basic function and structure of all filters are similar, it is the filtration rate that differentiates one product from the other. In order to select the right one for your requirements, it is important to gauge this attribute thoroughly, or at least an approximation of it.

In the case of inline filters, this value is measured as gallons per day. We’d go so far as to say that this is the most crucial aspect of buying water filters.


It’s important to understand the overall performance of inline water filters as it will be one of the most frequently used appliances in any household. Their work efficiency is measured by a number of things.

For instance, the claim to remove 99.9% of impurities must be verified as far as possible and it may be useful to focus on brands you know and trust. Also, remember to check whether the filter is able to eliminate odors, especially that of chlorine, from the water.


In order to function well, the filter must be compatible with the model of the refrigerator it’s attached to. This depends largely on the brand of both appliances in question. Optimum compatibility ensures easy installation and greatly reduces the chance of leakage. If a certain filter claims to have universal compatibility, it would be wise to take a deeper look into its mechanism as most often, it’s merely an advertising gimmick.

Price and Replacement Period

There is no shortage of brands that manufacture excellent inline water filters. However, filters need replacing and this is usually an expensive and time-consuming affair. This is why it pays to check out the replacement period of the model you buy.

If a filter needs to be replaced frequently, it can lead to unnecessary and bulky expenses. So, make sure to buy yourself one that lasts a while and is, therefore, cost-efficient.

Installation Procedure

The ideal water filter is easily installed. Having incurred a considerable expense, nobody wants to spend hours installing it. Most top-notch manufacturers understand this so it shouldn’t be a problem to find a model that is hassle-free to set up in 15 to 20 minutes.


With that, we have reached the end of our listicle and guide and hope to have brought you closer to the right inline water filter for your house.

But we’d like to help you out just a little more. To that end, we’ve rounded up our personal favorites which you might just end up favoring too.

The Watts Inline Filter is an excellent choice as a device that purifies to the T and also scores points for operational efficiency. Similarly, either of Culligan’s products would work well. It is an established brand and rather popular with homemakers.

Lastly, we’d recommend you take a good look at the CuZn ILFC 200 too. Functional and simple to use, it promises to deliver.

So go ahead, and take your pick from the very best.

Till next time!
