View On Amazon

This is the most expensive inline water filter in this review, but it’s worth owning which is why we included it. It is absolutely exceptional with its 4 stages of filtration, making it one of the best options for perfectly clean water.

Designed for installation under the sink, the Under Sink 4 Stage In-line Tap Water Filter is very easy to install. It installs perfectly to an existing faucet, so you have no need for a new or separate faucet.

Likewise, it is easy to maintain. Changing this filter only takes a few seconds and you wouldn’t need to shut off water flow. It flows fast, at a flow rate of 3 GPM and lasts 3 years. During these years the Under Sink 4 Stage In-line Water Filter will precisely purify your water eliminating all impurities and introducing beneficial minerals afterward to keep you and your family healthy.

View Features and Pros/Cons

Features We Love

  • Good flow rate – 3 GPM.
  • Filter life – 3 years or 10,000 gallons.
  • 4 stage filtration process.
  • Straightforward installation process.

Pros:

  • Easy to install.
  • Maintenance and changing of filters are both easy. You won’t need to shut off the water flow.

  • Produces perfectly clean water.

Cons

  • It doesn’t come cheap.

The 4 stages of filtration for which this inline water filter is popular are effective for removing any kind of impurity from the water.

First, the water goes through stage 1 filtration where sediments and particles such as sand, dirt, rust, silt and undissolved particles are removed. The stage 1 filtration has a precision of 1 micron.

Then, the water goes through stage 2filtration, where it is rid of chlorine, chlorinated hydrocarbons, and hydrogen sulfide. It is also at this stage that bacteria, algae, and fungi are prevented from growing within the filter media and causing any harm.

The stage 3 filter has a high-quality substrate that completely eliminates trace organic compounds like Trihalomethanes (THMs), pesticides, herbicides and residual disinfection by-products like chlorine. In addition, at this stage, Bacterial growth is also inhibited, water taste is improved and odor removed.

Lastly, the final stage – stage 4 – removes residual chlorine and adjusts the water pH level. The water produced is alkali calcium ionized. It contains natural calcium, sodium, potassium and magnesium ions that can be absorbed by the body and provides nutritional benefits.

What is an inline water filter if it cannot provide you and your household the purest water for drinking and cooking. With 4 stages of filtration, there is an almost impossible chance of drinking contaminated water when using the Under Sink 4 Stage Direct In-line Tap Water Filter BLUONICS Purifier System.

How an Inline Water Filter Works?

The best inline water filters fall into the class of physical filters that sieve out large and small particles from water. This filter work using adsorption – a process of filtration that uses carbon.

In this process of filtration, the particles stick to the carbon pores – usually referred to as activated carbon. Additionally, charcoal, coconut, and ceramic are other materials used in inline water filters.

Inline water filters are connected inline with water sources and as the water passes through them, they filter out particles which include:

  • Aluminum
  • Cadmium
  • Heavy metals
  • Hydrogen sulfide
  • Iron
  • Lead
  • Mercury
  • Glyphosate
  • Chromium 6
  • Bad taste, etc.

Besides, the best inline filters not only filter water but adds calcium, sodium, potassium and magnesium ions nutritionally beneficial to the body. Also, it regulates the pH of water which provides clean cooking or drinking water to large and small households.

Benefits of using inline water filters

Do you trust your water source enough to risk drinking water without any filtration? Assuredly, I doubt you do. Besides, even if you trust the water, the best inline water filter improves the taste of water and also keep you safe from harmful contaminants.

Multiple application

Most inline water filters have more than one applications and can be connected to ice makers, kitchen taps or refrigerators. Also, the Bluonics Under Sink inline water filter can be used as a stand-alone under sink filter.

Easy to replace

The beauty of an inline water filter is that it is very easy to replace after about 6 months depending on the type of filter. They usually have a quick-connect fitting or a push fitting that makes the replacement process very easy.

Besides, there is always an arrow on the body of the filters indicating the direction of water flow and the filter. However, we did come across a unit that had no arrow marking to indicate the direction of flow – pretty bad mistake on the manufacturers part.

Durable

Admittedly, inline water filters are known to be durable and last up to 6 months before needing any changing. However, some units like the EZ-FLO 60461N In-Line Water Filter and the Woder 10K-JG-1/4 Ultra High Capacity Inline Water filter has a filter life of 6 and 5 years respectively.

Affordable

Filter life

So, it’s now left for you to decide but in our opinion, an inline water filter with 1 years filter lifespan will serve you well.

Filter type

The best inline water filters clean water using materials such as carbon, ceramic and coconut. However, an activated carbon filter is more common than the other materials and provide fresh, clean water. Also, a ceramic inline water filter is good too likewise the coconut Inline filters.

Thus, whichever material you choose, it will definitely provide you with clean water.

Flow rate

The flow rate of the inline water filters is affected by the flow rate of your water source. Moreover, some inline water filters have a higher flow rate than the others because of their large valve opening. Check the flow rate or the valve opening of your inline water filter before you make the purchase.

However, most inline water filters have a flow rate of 3 GPM which is moderate. Love something higher? Check our last reviewed inline water filter above.

Price

Without a doubt, some inline water filters are more expensive than the others but, this doesn’t mean they perform better than the cheap inline water filters. Customer reviews and reviews such as ours, are the best way to spot a cheap but, efficient inline water filter.

Final Words
