You can conveniently install this unit in your home. But you need to have free counter space. You can conveniently suspense water right into your glass with this kind of unit and enjoy the fresh taste.

All countertop units are slightly different in design based on the manufacturer. But in general, all countertop water filters work in this fashion,

  • Connect your unit with the cold-water supply or the kitchen faucet. It will divert the cold-water pipe straight into your filter. We will talk about the installation of these units in detail in just a bit.
  • After fitting the filter in place, turn the filter on, and you are good to go.
  • Water will flow through the filters inside the unit as soon as you turn the water on. And this is where filter units might differ in terms of construction. Most popular and effective countertop water filters use activated alumina or carbon filters.

These filters are designed to trap contaminants within them when water flows right through. At this stage, the filters will remove fluoride, chlorine, selenium, and arsenic.

  • Some units also come with another filter called the reverse osmosis filter. It contains a semi-permeable membrane, and it catches contaminants such as pollutants, heavy metals, parasites, and viruses. This filter prevents these contaminants from passing through.
  • In the end, your water may flow through an additional remineralization filter that can alkalize your water by adding some minerals such as magnesium and calcium. It can provide you with water with an overall pleasant taste.

But most countertop water filters work incredibly quickly to get through the process and provide you with fresh and tasty water to drink. You will not have to wait for more than a second after turning the supply on and receiving water into your glass from the dispenser.

13 Best Countertop Water Filters of 2022 | Reviews & Buying Guide


Advantages of a Countertop Water Filter

There are various advantages that these countertop water filters have to offer. These are listed down as follows:

  • Cost-saving

If you spend too much on your disposable plastic water bottles, your countertop water filter can help you save a lot each month. Plus, it will be beneficial for the environment.

You might have to bulk-buy each time you run out of water. You will only have to purchase the unit and replace the filters every couple of months with such a unit.

The filter types are going to depend on the brand and model type that you are using. Some reverse osmosis units do come with higher price tags. No matter what filter you are after, there are different types available based on your budget.

  • Environment friendly

Most people prefer to go for bottled water when it comes to drinking water. It is not a wise choice, even if most people think bottled water is a much better option than the water that comes out of most people’s faucets.

But it is hazardous for the planet too. You can always recycle empty water bottles, but plastic does not go anywhere and break down properly.

It can only disperse into tiny microplastics and pollute seas and rivers, eventually drinking them. Bottled water can have toxins such as BPA at times. BPA has been associated with numerous health problems in infants and kids.

Therefore, a countertop unit is environmentally friendly and safe to use. Most manufacturers responsibly recycle their filters and offer incentives to their customers if they return filters directly back to them. It means they will not contribute to that global widespread plastic pollution.

  • Low maintenance

Unlike most faucet or whole house filters, countertop units need virtually no set-up. You also do not have to go through a lot of maintenance. They are pretty convenient for somebody who is not very experienced in handling DIY installation.

You can get the water filter started with minimal insertions, and most of them come pre-assembled. Once you have installed your filter, your system is ready to run. Make sure to go for an elementary unit to maintain, and its filter-changing job is not a big issue. In terms of maintenance, countertop units need the least maintenance.

  • Compact size

Countertop water filters have a compact design, and they are very space-saving. It means you can fit them conveniently in the area around your sink. Most filtration systems that go under the sink are bulky. These countertop units are slim and look pretty elegant.

Most of these countertop units are pretty space-saving. You can store these units wherever you want them to. You can even place them in your kitchen and your fridge. Moreover, you can even put them in your cupboard when you are not using them.

  • Easily moveable

These countertop units have a compact size, they will not weigh much, and you can conveniently move them. Plus, you can easily install them with your faucet. The lightweight design allows you to easily take it with you on your vacation in your RV, allowing you to drink clean water even when you are away from home.

  • No permanent

Most people tend to be hesitant to install under the sink unit as it is too permanent. You can disconnect it and reinstall it somewhere else, but it will take too much effort.

On the other hand, countertop units are not permanent fixtures. If you are planning on moving house, you can conveniently take your filter with you. You can easily take the filtration system off if you have decided that you do not want to use a filtration system.

  • Clean water

Countertop units can provide you with clean water on demand. You do not have to visit your local store and purchase bottled water in bulk. You can’t go for the same quality of drinking water without leaving your home.

Based on the type of system, your countertop unit must be at minimum able to filter out chemicals such as chlorine. It will make your water taste much better.

Disadvantages of a Countertop Water Filter

Countertop units might have many advantages, but they also have some disadvantages. We are going to have a look at them briefly,

  • Slower filtration rate

Countertop units are pretty effective at what they do. But not all of them are as effective in producing the best results compared to their under-sink counterparts.

Water filter pitchers take a few moments to filter water ready for drinking. They do not use pressure to force water through these fillets, or the process would have speeded up.

Based on the quality of your household water and the efficiency of your filters, you might have to wait for about 20 minutes.

  • Not highly efficient

Countertop units might be pretty effective in filtering water out from any contaminant. But some under sink systems are pretty good at this job.

For instance, some reverse osmosis units are most frequently equipped in under-sink models. They can filter out up to 99.9 percent of contaminants. If you are looking to go for these methods, you must have a bigger budget available.

  • Always-on display

No matter how appealing your countertop unit looks, you might still not want to show it on your kitchen counter. But if you are going for a faucet filter, you have to place it at a distance in front of our sink.

You will have to go for the filters that will look good with the aesthetics of your kitchen. And you might have to go for costlier options in this regard.

  • Single point of use

Many countertop units are linked with your kitchen sink faucet. It is the only location from which you can obtain clean drinking water with the help of POU or point of use systems.

Most countertop filters come with a design that allows you to connect them with the faucet. It means you will not be able to use your filter in another location, such as your bathroom.

As you cannot connect them to your main water system, countertop units will only affect the water quality for your kitchen sink and nowhere else in the home.

  • Less convenient

Some nights are less convenient compared to other filter styles. Water filter pitchers are pretty heavy for you to carry. You have to refill them before you use them and wait for the filter to filter the water before you can take it to drink.


Considerations Before Buying a Countertop Water Filtration System

Before you purchase a countertop unit, you have to consider a few features that you must consider when looking for these units. We are listing them down for your convenience.

Know What’s in the Water – The Water Test

If you want a countertop unit that can tackle specific contaminants in your water, you have to know what type of contaminants are there.

You can contact your local water supplier and go through the quality reports available to the general public. You should also receive this annually in your email or post.

These reports will tell you about the water quality of your local area. But, your home might still be different. And you must conduct a water test of your own to assess the water quality.

Go for those water testing kits available at your home improvement stores online. These kits have strips in them, and the strips have different reactions.

Just follow the instructions in the kit for the best results. You will have to hold this strip under running water for a specific period before you start comparing those colors on the chart present in the kit.

Different kits test different contaminants in your water. So, go for the kits that provide you with the ability to test out the broadest range of different elements, including pH, bacteria, nitrates, lead, fluoride, and chlorine, apart from water hardness.

After carrying out the test, you can determine the quality of your drinking water. The test can make it easier to decide what kind of countertop unit you need for your home.


Type of Countertop Water Filters

The next feature that you must consider is to choose the right type of countertop water filter. There are different types of these countertop units. Let us have a look at each one of them,

  • Water filter pitcher

These units are the least expensive and simple in designing all the countertop units available on the market. They are similar in looks to a standard jug. However, they contain a filter that traps impurities and contaminants in the water and makes it clear to drink.

It can take from 5 to 15 minutes to filter the water. The length of the time will depend on the guilt of your household water. Poor quality water will need more processing, and the filter will take longer to remove these contaminants.

Most filters can hold up to 12 cups of filtered water at one point. You must refill the pitcher front faucet once there is no more filtered water.

You will have to wait for the filtration process to complete. Some pitchers are particularly large, and they can hold up to 4 gallons of water. The larger pitcher might be more challenging to use

You will have to change the filters in your unit according to the instructions. These filters can be clipped into place to be pretty simple to use, and you can easily change the filters.

Cleaning the pitcher is not a difficult task either. Just remove the filters and soak them in warm soapy water. Some pitchers are dishwasher friendly but check the manual to be 100 percent sure.

  • Faucet filters

These units sit on your kitchen countertop right near your sink, and you have to connect them using a flexible plastic hose to connect them with your faucet.

These nuts are pretty simple to install, and they mostly come pre-installed. You will only have to connect the unit to your faucet and make it work.

When you press those buttons on your filtration unit, water fill starts flowing right away from your faucet into the system and directly out in your glass. So, you will not have to wait longer than as in the case of water filter pitchers.

Most of these filters are pretty sleek and modern in design. They are pretty compact and rough to fit in your kitchen workshop. You have plenty of options to choose from, and you will find a model with the right design for the space.

Some of these faucet filters also come with LED lights to notify you when to change those filters. Again, keep the time frames in mind because it is hard to judge how many gallons the filter has filtered.

  • Carbon filter

An activated carbon filter or a coconut carbon filter is a kind of filter that is frequently used in faucet water filters and water filter pitchers.

They are frequently used for removing chemicals and other organic compounds such as chlorine. Chlorine can significantly affect the odor and taste of your water.

Charcoal filters or coconut shells are both organically activated sources of carbon. Being activated refers to the open pores that allow them to trap any contaminants, called absorption.

A large filter surface area is needed to remove chlorine from water. The best distribution of carbon across filter media will enable the most effective removal of impurities. These filters perform better at eradicating larger molecules.

  • Ceramic filter

Like an activated carbon filter, this filter also comes with tiny pores spread across the area. These pores can filter larger sediments such as rust, dust, sand, and larger bacteria.

Ceramic filters are made of natural ceramic media that can trap impurities as water flows through those posters. The filter on the inside is sharply angled, and it can catch any particles that might have made it.

Ceramic filters are used in the first stage of filtration. They can remove sediments that can damage filters at a later stage.

  • Ultrafiltration

It is a membrane filtering process that can use precious metals to force water through semi-permeable membranes. This process is a more detailed methodology for eradicating contaminants. This filtration technique is costlier than the standard filtering methodology.

During this process, water flows inside the membrane at a very high temperature. Any larger solids can get caught within the membrane, and water will pass through.

This filtration process can remove contaminants like proteins, plastics, silt, silica, and viruses from your water. This process is frequently confused with reverse osmosis. But, both these methods are different.

Ultrafiltration has larger posters than the membranes present in reverse osmosis. The membranes here can range from 1 nanometer to 100 nanometers. These methods are different because they both tackle different particle sizes.

  • Water distillers

It is one of the unique water treatment methods that can turn water into steam to produce water free from any contaminant. These filters can remove lead, arsenic, fluoride, viruses, and other contaminants from your water.

Commonly, you will find a water distiller within a countertop unit that is directly connected with a kitsch faucet. This method uses condensation and boiling to remove some difficult impurities, like dissolved solids and salts.

These water distillers can evaporate water and can convert it into vapor. After that, it can condense back into a liquid state. When water evaporates, contaminants like bacteria are eradicated because they cannot be turned into steam.

They remain behind in the water chamber when water turns into vapors. Water is then turned back into the same state, but it does not have any contaminants.

From here, the water is sent through a carbon filter after condensation. So, it is because some contaminants can even remain in the water during its gaseous state.

  • Reverse osmosis

These filters are commonly found in filters that go under the sink. However, some more expensive units have these filters in them.

It is a highly efficient method to filter water. It can eliminate up to 99.9 percent of all contaminants in your water. This process is similar to ultrafiltration, and water is forced into a semipermeable membrane at high pressure.

But it wastes water too, and the waste to pure water ratio is around 4:1. It means one gallon of clean water is produced for every four gallons of wastewater.

It seems like the wastage is too much here. But this process does not waste more water than any other waste-based kitchen appliance.

You will only have to decide if you want to go for a system that produces wastewater more efficiently or a less effective system that filters close to 100 percent of the water that passes through it.

  • Gravity water filters

There are gravity water filters, too. They use gravity to force water into the filter cartridge to get rid of any contaminants. The best part is that you do not need to go for any electrical installation or plumbing is required.
