Our Review

Pros

Cons

Overall Rating – 4.5

Is your tap water contaminated with lead, pesticides, or chemicals? 

 

The Clearly Filtered 3-stage under sink water filter system may be the right choice for you.

 

The Clearly Filtered 3-stage filtration system removes over 99% of trihalomethanes, PFOA, pesticides, volatile organic compounds, and other chemicals. 

 

That’s disgusting stuff, so we’ll just assume you’d rather not have all of that in your water supply. 

 

In this post, we review the Clearly Filtered 3-stage water filter. We talk about the features, what it filters, and the pros and cons. We’ll give you all the details to explain why this is one of the best under-sink water filters available.

Clearly Filtered 3-Stage Under-Sink Filter Features

The Clearly Filtered 3-stage under-sink water filter is simple to install and offers some of the best contaminant filtration you can find. It cleans more chemicals and contaminants than most other filtration systems, removing over 99% of PFOA, Pesticides, Chromium, and organic compounds. 

 

This great contaminant reduction comes through the use of three separate filtration stages. Each stage targets certain contaminants within the water. That allows the Clearly Filtered system to remove much more than a single or dual stage under the sink system would. It even removes more than a typical reverse osmosis filter.

The Clearly Filtered 3-stage system removes:

It removes even more. For a more complete list, see the test results

Water passes through three filters. The first filter stage is a carbon filter. It removes much of the sediment from your water, but also will remove contaminants that affect taste and odor of the water.

 

The second filter stage removes heavy metals and VOCs. This stage also reduces the amount of herbicides, pesticides, chromium, PFAS, and more.

 

The third filter stage is a fluoride and arsenic filter. This uses their proprietary Affinity Filtration Technology to purify your water. Unlike a reverse osmosis system, this system leaves the beneficial minerals in place, leaving you with tastier water.

 

The Clearly Filtered 3-stage under the sink water filter system is compact. It sits flush against the cabinet, taking up only about three inches of your under-sink space. This is very small for an under-sink unit. 

Installation is simple because it only connects to the existing cold water line. You can mount it to the cabinet, but it works fine sitting on the cabinet floor. 

 

With the Clearly Filtered 3-stage system, you won’t get the flat tasting water that sometimes comes from other under-sink filters. This is because it doesn’t remove most of the minerals from your water the way something like a reverse osmosis filter might.

 

Maintaining this system is a breeze. All you’ll need to do is switch out the filters every now and then. That just takes unscrewing the old filter and screwing on the new one, so it’s simple.

 

This filter is on the pricy side, though, both for the initial cost and the replacement filter cartridges. More than one Clearly Filtered under-sink review mentions a significant drop in water pressure, too.

In the Package

The package comes with everything you need to use your Clearly Filtered 3-stage under-sink water filter.

How to Install

You won’t find another under-sink filter that is easier to install than this filter. It’s DIY-friendly, and you should not need a plumber to install this system. 

 

Installation of this under-sink water filter system does not require any permanent changes to your home. You don’t even need to mount it to the cabinet wall, it can just lay on your cabinet floor. This will not impact how well the system functions. Those in a rental home can easily remove everything and put it back to the way it was before installation.

Here are the steps to install the filter:

That’s it. As you can see, this is not difficult at all. Clearly Filtered also has a video describing this process. 

Maintenance

Maintenance on this filter couldn’t be easier. The only regular maintenance is changing cartridges. Filter cartridges are designed to clean 2,000 gallons, which should last you about a year, depending on how much water you use.

Filter Replacement

The filters are easy to change. You don’t even need to shut water off because the system has built-in shut-offs. Unlike with other filters, you won’t even need any tools to change the cartridges. 

Here’s how you do it:

Clearly Filtered has a video showing this process.

How Does It Stack Up Against Competitors?

When you’re trying to make a good decision about which water filter is best for you, you really need to compare it to the top competitors to see how it stacks up. We’ll compare it to the Waterdrop G3 reverse osmosis system and the 3-stage under the sink Pelican PDF-1000VF.
