Best Under Sink Water Filtration Systems in 2021

Unfortunately, most tap water is full of contaminants. Contaminants such as bacteria and germs, as well as things like metals. Each one of these things is incredibly toxic, and can easily lead to a wide variety of different issues and health problems, none of which you will want to deal with and experience.

Best Under Sink Water Filtration Systems

Sadly, though, this is the state-of-affairs when it comes to tap water. There are many different reasons for this, but much of it has to do with the fact that the filtration methods used by most major cities aren’t sufficient enough to remove those metals, germs, and bacteria, and as a result of this, when you drink tap water, you are drinking incredibly dirty water.

For most people, the easiest solution is to use some kind of filtration mechanism. Or, to just buy bottled water. But, as you are probably well aware, buying bottled water isn’t exactly the most cost-efficient way of dealing with the problem. Instead of going for that, you should purchase a water filtration system, because a good water filtration system serves as a way of dealing with the problem of dirty water head-on.

A lot of different water filtration systems are out there, and it’s pretty difficult to find the best water filtration system, if you are unfamiliar with the basics of how these filtration systems actually work, what they do, and the myriad of reasons why you should buy one.

Under Sink Water Filtration Systems

You can find a lot of different water filtration systems. There are water filtration systems designed to be placed on your countertop, and then there are water filtration systems that are designed to be used by being placed underneath the sink, connected directly to the piping system itself, rather than just the faucet.

Each one of these systems has its own set of distinct advantages, and in this buying guide, we’re going to be looking at both of these systems, and what they have to offer. Without understanding how these water filtration systems operate, it’s difficult to determine which one will be the best one for your needs.

Along with that, in this buying guide, we’re going to be taking an in-depth look at the specific functions that both countertop water filtration systems, as well as under sink water filtration systems, perform, and how these functions affect the overall experience with the water filtration systems.

Once we’ve looked at that, we’re then going to take a look at the individual features and attributes that under sink, and countertop water filtration systems come with, and how these features and attributes affect the water filtration system and what it can do. More importantly, though, you’ll learn what you need to look for and consider when searching for the very best countertop, or under sink, water filtration system for yourself.

Everyone has their own needs and desires when it comes to the type of water filtration system that is ideal for them. Reading this guide is going to give you all of the clarity you need, to understand what you need, and what is available, so that you can drink water that is nice and clean, using the ideal water filtration system.

Water Filtration Systems

What Is A Countertop Water Filtration System?

A countertop water filtration system is exactly what it sounds like: a water filtration system that sits right on top of your countertop. And, since it’s on your countertop, where there isn’t any exposed piping or direct connections to the water pipelines that lead to your faucet, a countertop water filtration system has only one choice, when it comes to how it is able to filter out your water, and that’s by attaching themselves directly to your faucet.

With that being said, though, there is one type of water filtration system that is, technically, a countertop water filtration system, but it doesn’t directly connect to your faucet.

This system is known as a “water filter pitcher”, and it’s a pitcher that holds water, water that comes from your faucet, and then filters it. But, it’s a bit more cumbersome and annoying than the other filtration systems, since you have to fill it up constantly.

Using a countertop water filtration system, the water is poured out of the tap, and this water is full of contaminants as it comes out of the tap. But, when you turn on the water filtration system, the water filtration system can take that water out and then, using a small pipe, the water transferred to the water filtration unit, filtered out, and it comes out through a pipe attached to that unit. You can, more often than not, turn on the water filtration system by turning a small dial, but if that dial isn’t turned, then regular water will come out of the tap.

Ultimately, a countertop water filtration system is a small water filtration system that sits right on your countertop. It connects to the faucet, usually, and then it pulls water from the faucet into the system’s unit, filters the water, and then releases it. For most people, it’s the best option, since it’s so convenient and so easy to use. If you want something that is low maintenance and easy to set up, then a countertop water filtration system is the way to go.

Best Under Sink Water Filters

What Is An Under Sink Water Filtration System?

Since a countertop water filtration system is a water filtration system that sits on your countertop, it makes sense that an under sink water filtration system is a water filtration system that sits underneath your sink.

That is exactly what this type of water filtration system is, but, more importantly, the filtration method is a little different from that of a countertop water filtration system.

Most of the time, the under sink water filtration system will be underneath your sink, and it will be attached to the main water pipe. This is the water pipe that brings water directly to your faucet, and you install this filter to that main pipe. By doing this, you allow the water to pass through that pipe, as it normally would, so that it can then come out of your faucet. Unlike the countertop water filtration system, it doesn’t come out of a separate pipe.

However, there is another type of under sink water filtration system that is used quite a bit. But, due to the advancements with these types of systems, it isn’t as popular, and isn’t recommended, unless you have the space to accommodate it.

Using a series of pipes that connect to the main water pipe, and then to the water filter, you can connect the water filtration system to another faucet, next to your main faucet. This faucet comes with the under sink water filtration system, and it serves as the faucet for filtered water.

Of course, the problem with this particular water filtration system is that it takes up a lot of space, and it’s more difficult to install. And that’s not even getting into the extra costs.

Top 10 Best Under Sink Water Filters

Ultimately, though, an under sink water filtration system is a type of water filtration system that is located underneath the sink, and this particular system filters the water directly from the pipe, either routing it to a separate faucet or the main faucet.

It’s a more efficient method for filtering your water, but you will need to replace the filters more often, and it is more expensive.

Which One Should I Choose?

If you want convenience, then a countertop water filtration system is the ideal choice. But, if you want something incredibly powerful and efficient when it comes to the water filtration process, then an under sink water filtration system is ideal.

When Searching For The Best Countertop/Under Sink Water Filtration System, What Should I Look For And Consider?

In this section of the buying guide, we’re going to dive into the things you need to look for and consider when searching for a countertop water filtration system, and an under sink water filtration system. Using this information will make the buying process much easier.

What Type Of Water Filtration System Do You Want?

If you want a countertop water filtration system, do you want to use a water filter pitcher or a more traditional countertop water filtration system?

With a water filter pitcher, you can use the water filtration system anywhere. But, the filtration process isn’t as thorough, and it isn’t as efficient.

If you’re using a more conventional countertop water filtration system, the system stays in place on the countertop, and more thoroughly filters the water. In general, it’s the better choice, unless mobility is what you want.

For an under sink water filtration system, you can either get a water filtration system that attaches to your pipes, and routes the water to your faucet, or a system that requires you to install a separate faucet.

Using one that requires a separate faucet can be useful, but it requires more maintenance and is more expensive. With a more conventional under sink water filtration system, it’s much easier to set up.

Ultimately, it depends on your preferences and what works best with your situation.

What Does The Water Filtration System Remove?

Every water filtration system has its own set of things that it removes. Some water filtration systems are significantly better at removing metals, for example, and other water filtration systems are better at removing things like germs and bacteria.

You’re going to find water filtration systems that are good at removing all kinds of things, and while there is no definite answer as to the type of things that your water filtration should be good at removing, you should look for a water filtration system that is able to remove these things: heavy metals, lead, chlorine, odors, volatile organic compounds, and bacteria. If the water filtration system you are looking at buying can’t filter out all of those things, then it probably isn’t that great of a water filtration system.

Keep in mind that some types of water filtration systems will be more effective at removing these things than others will. If you are buying a smaller countertop water filtration system, it won’t be as good at removing those things.

How Many Gallons Of Water Can The Water Filtration System Filter Before It Needs To Be Replaced?

Every water filtration system that you buy is an investment, and you will want that investment to last as long as it can.

Some water filtration systems can filter up to eight-thousand gallons of water before the filter needs to be replaced. Other water filtration systems can only filter two-thousand or three-thousand gallons of water before the filter needs to be taken out and replaced. And then, there are some water filtration systems that can only filter five-hundred gallons of water, before the filter needs to be replaced.

You’ll find a lot of variety, in this aspect, but it’s very important that you consider how much you will be using the water filter, and the amount of gallons that is appropriate for you.

If you’ll be using it a lot, then you should buy one that can filter out, at the very least, three-thousand gallons of water. If you won’t be using it that much, then two-thousand or one-thousand gallons should be ideal. And then, after that, you’re going to need to replace the filter, so that it can continue to work well.

Best Under Counter Water Filters

How Easy Is It For You To Install The Water Filtration System?

Finally, the last thing you need to consider is the process of installing the water filtration system. It does vary, depending on the type of water filtration system you are buying. But, simplicity is key, and make sure to read about the ease of the setup.

With a water filtration system that is easier to set up, it’s much easier for you to replace the filter and to repair it, if needed.

Conclusion

Countertop and under sink water filtration systems are both excellent water filtration systems that can have a great effect on your health. By following this guide, and considering the information we’ve laid out for you, you’re not going to have any problems finding the best water filtration system for yourself!
