Water is life’s utter necessity. It makes up about 60% of the body and is involved in many critical body functions, ranging from controlling the temperature of the body to flushing out contaminants and protecting body tissues, joints, and spinal cord. In carrying out many of the chemical reactions of the body, water also plays a critical role. 

Without water, it will lack the proper form and fullness of parts of the body, such as the skin. This article will go into detail about the Best Countertop Water Filter 2021 so that you drink the best quality of your water to keep you safe.

How Does Water Filter Works?


The demand for water filtration has never been higher because of the high risk associated with impure water. As we cope with pollution, climate change, and a rapidly rising population, our natural resources are also under threat. Tap water, which is supposed to be safe for drinking, can sadly be very dangerous as pollutants affect the overall quality of water.

A countertop water filter is a cost-effective alternative to bulk-buying bottled water if you are not a fan of the taste or consistency of your home’s drinking water. It cleans out the pollutants in the water that give it an odd taste, such as chlorine and copper. 

In all drinking water throughout the world, these pollutants are present. Although they can not affect your health, when those pollutants are filtered out, most people find that water tastes far more pleasant.

The best water filter for countertops is commonly elegant in style and portable. Countertop water filters are virtually ready to go from the moment you buy them, unlike under sink water filters, which are bulkier and need a more detailed installation. This makes them a good choice for consumers who are looking for an easy means to generate filtered water immediately.

We have found the best representative for every form of countertop water filter after several rounds of selection based on product specifications and checked customer reviews.

With this unit, the main difference being that this system has a dedicated filtered water faucet connected to the filter system instead of the filtered water coming from the faucet adapter. 

This is the same sort of faucet that you would hope to get with your installation of an undersink water filtration device. This can make the dispensing of water more convenient, depending on your needs. 

This is another system around the filtration system without a case, so it is not as appealing. This machine travels well when you want to carry it with you because of the faucet attachment.


  • A sediment filter that catches dirt, dust, sand, and rust particles is the 1st stage. The 2nd stage is a filter of granular carbon that eliminates pollutants such as chlorine, organic volatile chemicals, and any other compounds causing odor. 
  • The 3rd stage includes the real Reverse Osmosis Membrane, which focuses on contaminants such as lead, arsenic, chromium, fluoride, TDS, radium and others that are most challenging to extract. 
  • A Post Activated Carbon Filter that performs a final pass on the water, eliminating any potential tastes or odors that might have made it through the first three stages in any way, is the 4th and final stage.

The Express Water Countertop Reverse Osmosis Water Filtration Device undoubtedly catches the eye at first glance. It really looks like some sort of science experiment in some respects, or maybe a method of water softening that is usually tucked away and out of reach. 

With this device, four bottles are connected to each other and attached to a metal tray, with the middle protruding from a metal faucet spout. The device is directly connected to the tap faucet on the faucet head and uses a special attachment that allows you to move easily from standard tap water from the usual faucet to the faucet of the filtration system.


  • Removes almost all contaminants. This is a seriously effective filtration device that removes from your water almost every form of contaminant. Many typical household filter systems simply use a carbon filter, but on top of that, this system uses three additional methods. A four stage reverse osmosis device is unbeatable if you’re searching for the purest water possible. 
  • Easy to install. The Reverse Osmosis Water Filtration System for Express Water Countertop uses a simple and easy four-point setup that takes only a few minutes for complete installation. In the end, what you really do is hook a tiny hose up to the head of your faucet, something anyone can do. 
  • Easy to use. It is as easy to get filtered water from this machine as flipping the switch on the faucet head of your sink. This routes the water into the reverse osmosis device instantly. Simply turn the switch back until you’re finished and you can use the tap on your sink like you usually would.


  • No casing which is not appealing. This system is going to throw things off a little if you’re someone who enjoys a tidy, unified, and minimal appearance in your kitchen or bathroom. Express Water did not find it appropriate to provide a cover for the device for some reason, so you’re forced to only put an unsightly set of plastic tanks on your counter.

Choosing the Best Countertop Water Filter 2020: Buyer’s Guide


The best countertop water filters will change your life for the best.The contaminants in your drinking water will be removed with the use of these filters.

Not only can the use of countertop water filters eliminate the toxins and harmful chemicals in your water, but your drinking water will also be alkalized, making it safer for your health and optimal for weight loss.

Countertop water filters are designed to be very lightweight so that they can fit without being bulky in the room around your sink. Moreover, these water filters are easy to bring, and if you go on vacation, in your vehicle, and even in your yacht, you can even take them. 

The explanation for this is that, in order to use them, these water filters do not need permanent installation or plumbing.

To make sure you select the right countertop water filter, here are a few steps you can take. 

Price Range

Before you begin to search for one, you should determine how much you are willing to spend in a water filtering system. You risk going down the rabbit hole if you don’t, and spending more on a model than you’re expected to. 

Water Test


Checking your water is the second thing you should do before purchasing a water filter. To test your drinking water, there are a lot of water test kits you can use, and most of them come at reasonable prices. Some models may also be able to tell whether pesticides, herbicides, and pharmaceuticals are contaminating your water, but these appear to be more costly. If you believe, however, that your water can be polluted by these chemicals, you can also test it.

Research about Contaminants 

Once you find out which pollutants are in your water, to find out which of them are more dangerous, you can do some quick online research. This can be evident in some ways, since anyone can say that lead is more dangerous than chlorine, but it can be more difficult in others. But the difference might not be so clear if you had to pick between nitrates and chloramines. Do your research, then. 

Find a Compatible Model 

You can look for a water filter that can avoid most of them, now that you know the pollutants are the most dangerous in your water, and their estimated numbers. If none of the water filters you find will eliminate all of the pollutants in your water supply, selecting the one that can remove the most dangerous ones would be the best choice.


For countertop water filters, you should make sure to look into the various sizes available. 

If you are planning on buying a water filter, it is prudent to calculate the room near your kitchen sink. Imagine the annoyance of buying a machine and realizing that it didn’t fit in your available kitchen counter comfortably. 

You should also remember size versus available space if you are thinking of buying a water filter pitcher. Many individuals want to store their pitcher in the fridge, so you might want to make sure you don’t buy a design that’s too large or too wide to fit properly.


Countertop water filters use cartridges that need to be replaced after a specified time span. Many brands require the replacement of cartridges every four months for up to one year. 

Choose the product that you can change conveniently, the filter is available for replacement and the cost is affordable.

To Wrap Things Up

There is no such thing as a universal best model, as you may see in our countertop water filter reviews. Every model is best suited for a particular task. Some filters can extract more chlorine but less fluoride than others. Others will do a better job at removing heavy metals, but will not be so effective at removing pharmaceuticals. 

You can first test your water to see which pollutants impact it if you want to find the best countertop water filter. Once the pollutants are detected, you can easily choose a model that will be effective in preventing them from reaching your drinking water.

All of the best countertop water filter 2021 in this list are worthy, and there is one here to fit your desire, depending on how much you want to spend or how much you want to filter your water.  

The filters do an excellent job of eliminating toxins from tap water, making you want to drink more water, providing a healthier drinking experience. Start investing in a countertop water filter system today.
