Countertop water filter is a point-of-use (POU) water filtration system that is very effective in eliminating most contaminants found in water. They sit on the Kitchen’s countertop to provide clean healthy water for the family.

Countertop filters are designed to be portable, affordable and convenient which is why they’re one of the most common home water filters.

After evaluating tons of water filters, we determined the most efficient countertop water filter to be the Big Berkey Filter which has capacity to filter 6,000 gallons of water throughout its lifespan. AquaTru, Apex and Aquasana are also good alternatives to consider.

Criteria For Choosing A Countertop Filter


Here’s what to look for when purchasing countertop water filters:

1. Evaluate Your Home/Family Needs:

Every home and family has different water purification requirements. It’s essential to consider your individual needs and preferences to decide whether a countertop water filter is best for you or if you should look into alternative options.

You should also consider how bad your water may be locally.  Not only are there worries of heavy metals in local water supplies, but in some areas it’s concern over the presence of bacteria, herbicides, and pesticides.  The most important factor is the amount of water you use.

Countertop devices typically only hold one or two gallons at a time. Does your family need more water than this at once?

Another factor to consider is the single-faucet setup. Do you have multiple faucets you want filtered? If so, a whole house filtration system might be a better bet.

2. Consider Specs & Features:

Here are a few of the most important countertop water filter features to consider during the buying process:

Filter Type:

Some filters have a filter for all types of contaminants. Others have a more specialized use for a single contaminant, such as arsenic or fluoride.

Filter Longevity:

How long will the filter last before it needs to be changed? Depends on how many gallons of tap water are treated. Most are between 3 months and one year, although longer-lasting filters are available.

Filter Speed:

How quickly does the device remove contaminates and filter water? Many do so quickly, but some methods, especially steam distillation, can take hours.

Water Capacity:

How much clean water does the storage tank hold at a time? Some models feature large stainless steel tanks that can hold many gallons.

Connection Type:

Does the device connect via hose to your kitchen faucet? Make sure your faucet is compatible with the specific connection type.

Note that almost all of these models are easy to install with no tools, so installation type isn’t really a necessary factor to consider.

3. Consider Alternative Options

A countertop water filter is just one of many water filtration systems for home use. One of the most common alternatives is a pitcher filter. These work in much the same way as other filters, except that they are filled with water and placed in the refrigerator.

Another common option is a whole house water filter. These systems connect to your home’s main water line and remove contaminates right there, so that all of the water in your home (sinks, toilets, showers, etc) is clean, safe, and filtered.

This means you don’t need to install multiple filters (in the kitchen and elsewhere) and just leave it all the filtering to the one master unit.

What Is a Countertop Water Filter?

A countertop water filter is a simple device used to filter and purify water. Despite their overall simplicity and straightforward design, the best countertop water filters are remarkably effective at filtering out contaminants and heavy metals from drinking water. A countertop water filter is unique in that it sits on your countertop.

These filters most typically consist of a storage container which also houses the filter/purification element itself.

Some models connect directly to the faucet with a thin water line. You must pour water directly into others. Some models have a water collection tank that stores the filtered water. A spigot is used to deposit the water into drinking containers and cookware.

Types of Countertop Water Filters and How they Work

There are a variety of filters of this type.  Some of the most popular filters include the following:

  • Reverse Osmosis Systems
  • Water Distillers
  • Water Ionizers, and
  • Faucet or Sink-top Systems

Reverse Osmosis (RO) systems are very popular and for good reason as they are quite effective.  These filters use a system to force water through membranes that filter out contaminates and leave behind a healthy and pure water to consume.

RO systems between manufacturers often look identical as the concept and methodology of how RO works is so straightforward.  Essentially, you hook up your water source into the RO system that has several filters that the water must go through until it reaches a large tank that holds the filtered water that is ready for consumption.  Very often, the filter portion of the RO system is a three-stage filter that acts to remove contaminates and heavy metals.

The RO system, while not elaborate, does take up some space between the filter system and the final water tank.  As a result, you will almost always find these systems directly underneath the kitchen sink inside the cabinet.  Recently, there have been some new innovative RO systems that have been made smaller in size and attractive enough to live on the countertop area.

Installation for RO systems isn’t difficult, though it is typically done by a plumber or service technician.  It can, however, be done easily by those that like home improvement projects and are a bit handy. 

The process is mainly to place the filter stages and water tank in the under-sink area and run some new tubing to deliver water into the RO system and then out to your faucet.  The filters typically last 6 to 12 months, depending on the household and how many gallons of tap water are treated. The filters can be cartridge style and are easily done by the homeowner or maybe a service technician.

Water distillers are a whole different type of filters for treating water.  This method is also very easy to understand and an age-old method of making things safe, that is, by boiling them.  Boiling water and collecting the steam and then capturing it back into liquid form is how it works. 

The idea is that as the liquid boils into steam, the sediment, heavy metals, and other contaminants are all left behind.  Distilling can also remove fluoride as one of its strong suits.  The only exception to what distilling can’t remove are any chemicals that may be in the water that would boil at the same time and get captured with the rest of the water steam.

Installation is not an issue with water distilling systems as we’re mainly talking about a separate system that is housed on your countertop.  You fill the system’s reservoir with water and then the distiller has a process to boil the water within it, collect the steam, and finally capture back as treated liquid water.  So, it’s a self-contained system and typically not anything the consumer needs to install in their kitchen.

The distilling concept is simple and is usually well executed, depending on the system you purchase and how well it’s executed.  As always, read the reviews that we have on this site to make sure the system you’re considering is well constructed with the right materials and attention to detail.  When distilling is done right, you are left with a pure water ready for drinking that is free from fluoride.

Water ionizing systems are again a very different methodology than the others we’ve described so far.  Here, the process is called electrolysis and involves the use of positive and negative ions to turn water acidic and alkaline portions.  The idea is that the more alkaline water may have health benefits in terms of helping with higher pH in humans.

Installation of ionizing systems is a similar story as distillers.  You are buying a new water treatment system that will live next to your sink or wherever you’d like to place it.  This unit is self-contained and does all the work within itself to deliver the final water product to you.  The only installation for some units is to feed a water line directly into the system, which is not a big job.

You should know that there is debate over the health claims around drinking alkaline water.  That said, these filters have seen faithful use by many, and it’s also argued against the pleasant taste of the water produced.  Ionizing systems are at the upper end of these types of water filters and you can expect to pay a minimum of several hundred dollars for a unit and most often the units are significantly above the thousand-dollar mark.

The final filter type is also the most standard filter in most households, that being the faucet or sink-top system.  These systems have been around for a long time, can be quite economical, and are very convenient.  The systems that this type encompasses range from traditional membrane filters to ceramic filters and even new sediment types that add desirable minerals to your drinking water.

These systems have different implementations, but they have traditionally presented to the consumer a new small spigot next to their normal faucet that delivers the filtered water.  There are even some traditional systems that attach directly to the faucet itself and do the filtering right there and deliver the treated water right from the faucet.

As you can imagine, these systems can be the most convenient in terms of taking up the least amount of room in your kitchen and conserve your countertop space. These models use activated carbon and other methods to remove bacteria and other contaminates from tap water and deliver great water taste.

The installation of these systems and difficulty depend on which one you get.  The last and most traditional one we mentioned couldn’t be easier to do and you simply just screw in the filter into your faucet. 

Others may require the owner to be handy or leverage a plumber, especially if a new spigot needs to be mounted on your sink.  Other system may simply get water fed into it from a tube and then do their work.  In those cases, you simply need to provide that initial water hook up to the device.

One final thought in terms of countertop filters is that you even have pitchers that have built-in water filter technology.  These couldn’t be any easier to use and simply are pitchers that take the water you pour into them and then the water goes through its filter and then settles into the reservoir. 

Then, you simply just pour water from the pitcher and consume.  No installation, nothing that has to sit on your counter, and it couldn’t be simpler.

Countertop Water Filter Pros and Cons

You have a lot of different options when it comes to water filters, so it pays off to make sure a countertop water filter model is the one for you. Here are the main pros and cons of this type of water filtration system:

Countertop Water Filter Pros

  • Affordable – These filters can be an arm and a leg cheaper than many other filtration options, like whole house filters
  • Small Size – Countertop filters are typically very small, are not heavy, and don’t take up much space
  • Convenient – These devices are located right next to your kitchen sink for quick and easy drinking water
  • Minimal Installation – At most, a countertop water filter requires connecting a small attachment on the end of the hose to your faucet
  • Efficient – The best models efficiently remove harmful contaminants from your drinking water while simultaneously leaving healthy minerals behind

Countertop Water Filter Cons

  • Single Faucet – These filters can only connect to a single faucet at once to remove contaminates
  • Slow Filtration – Most countertop systems filter your water very slowly, so consider the flow
  • Small Capacity – Most countertop filters have a small clean water storage tank of roughly one or two gallons

Take all of these pros and cons into consideration to decide if this particular type of water filtration system is right for you.
