One of the most important things to consider when selecting an under sink water filter is the systems filtration efficiency. 

This is determined by how much output the filter produces, as well as how many contaminants it removes. 

While it’s easy to get caught up in looking for the most efficient filter, I think that it’s better to focus on what contaminants are in your tap water and choose a filter that will target those. Then choose the highest flow rate of those models.

You also need to make sure that you choose an under sink water filter that is compatible with your type of faucet. 

Finally, think about the installation process and whether or not you will be able to complete this work on your own. 

Some filters are just easier to install than others. And choosing one that you can install on your own will save you money because you won’t have to hire a plumber.

Benefits of Having an Under Sink Water Filter

Having an under sink water filter allows you to have clean and filtered water on demand from your faucet. 

This means that you can easily remove dangerous substances and contaminants from your water without having to use a smaller filter or dealing with the hassle of constantly filling up a pitcher filter. 

Homeowners who want filtered water all the time, are ready to move away from using bottled water, and want to improve the way that their tap water smells and tastes will benefit greatly from having an under sink water filter.

Because under sink water filters are generally easy to install, they are a great option for most any homeowner. 

Additionally, they don’t take up space on the counter, which is great if you have a small kitchen and aren’t willing to sacrifice a lot of countertop space. 

Under sink water filter systems do not require nearly as much maintenance as some other water filter types. 

This means that you can install your filter and use it right away without worrying about keeping an eye on how it works or worrying about leaks or maintaining the system. 

Features to Look For

You definitely want to consider the capacity or lifetime of the under counter water filter. 

While these systems don’t require as much maintenance as other types, you will have to change the filter from time to time.

Another feature that you need to look for is what type of filtration process the water filter uses. 

Some have more advanced filters, and these will be better able to remove larger amounts of contaminants.

Finally, consider the size. 

While there are some very small and compact under sink water filters, there are also some that are significantly larger. 

These sometimes have more advanced filters in them, but they do take up more room.

Using Your New Under Sink Water Filter

The first step in being able to use your new filter is installing it. 

This process is involved, but can generally be managed if you are willing to put a little work into it. 

Some water filters come with all of the parts you need for installation, which makes this process easier, as you won’t have to purchase any additional components. 

Unless you have prior installation experience, I recommend buying a system that comes with all of the components that you need.

After you have your water filter connected then it’s a simple matter of either using your regular faucet or the included faucet that came with the water filter. 

You don’t have to do anything special to get the water that you need.

What to Watch Out For

There are some under sink filters that tend to have very poor water pressure and will release a slow flow of water. 

While this isn’t a deal breaker, I highly recommend opting for a high water flow system.

Another problem to be on the lookout for is when a water filter leaks or wastes a lot of water. 

This will increase water costs and lead to possible water damage.

If you hook up your under sink water filter on your own, then you need to make sure to check it for leaks, especially right after installation.
