Buying Guide

What Is A Countertop Water Filter?

A filter that you can easily install close to your sink is called a countertop water filter. It has a spout for easy pouring and it is also designed in such a way that it improves the quality of the water that you consume daily. It helps to remove the contaminants from your drinking water very efficiently– almost 90% of the contaminants are removed by all the models in the market.


You can not only drink safe and pure water from the countertop filter but you can also help in saving the environment as well from the plague of plastic bottles. Surely, a water filter will keep you away from the disposable plastic water bottles resulting in less usage of plastic and a healthier environment.


These countertop filters are not very large in size. In fact, they can easily be placed near your sinks without any difficulty. Moreover, these filters are portable so you can carry them wherever you want. You can also take them with you when you go on a picnic or for any recreational activity. These filters are not permanently installed, which is why they can be easily transported.

How Can The Installation Of A Countertop Water Filter Be Done?

The process of installing a countertop water filter is not very tedious. All you need is a wrench (which can also be of plastic in some cases). The process is as follows:

  1. Place the filter so that it is not only near the faucet but also does not hinder your movement while you are working.
  2. Unscrew the aerator from the faucet head.
  3. Screw the filter onto the faucet if the thread is outside the faucet. In case the thread is inside the faucet, you need to use an adapter for the connection. Make sure you do not screw the adapter too tight as it can be damaged unintentionally.
  4. Then, connect the diverter valve with the faucet. After that, when the water is run, it should flow out from the faucet.
  5. Turn the diverter valve so that the water starts flowing from the water filter.

Why Do You Need A Countertop Water Filter? Assessing The Pros And Cons:

Advantages of countertop water filters:
Countertop filters are space-efficient so they don’t take up much space. However, this quality does not affect its capacity to hold an ample amount of water and some filters can even hold up to 5 gallons. They can also be installed easily. If you get the ones with a faucet, you just have to attach it to your kitchen faucet and it is ready to use. They are efficient as well as they can remove most of the contaminants along with detestable taste and smells like that of chlorine, pesticides or pharmaceuticals.


The maintenance of these filters is also quite easy. You simply have to change the cartridges once their maximum capacity is reached. There are different features that help you determine when to change the cartridges. You can just tick the number of gallons of water used with the counter provided in some of the models. Also, some have a colour-coded system that warns you when to change the cartridges.


Most importantly, you get water that is beneficial for your health with minerals added back to it by remineralizing water. Some countertop filters have this feature where minerals like calcium and magnesium are added back to the water with a post-filter attachment. Therefore, the water that you are getting has the contaminants removed and the minerals added. Priming the filter cartridges of countertop water filters is also pretty easy. Some of the manufacturers provide complete instructions in the form of a manual and some through videos as well.


Disadvantages of countertop water filters:
The pros of any product are accompanied by certain cons too. The same is the case with these countertop water filters. They affect the decor of your kitchen and do not look as appealing as water filter pitchers. Moreover, in terms of efficiency, there are lots of filtering solutions that filter far more contaminants than countertop water filters. Another drawback is that they are really very slow. Some faucet water filters can have a faster filtration rate than the water filter pitchers but still, they are slower.

How Does A Countertop Water Filter Work?

The working of a countertop filter is quite complicated although it may seem simple at a glance. It also varies with different products as some water filters may use extra stages for their filtration process. Most commonly, the countertop water filter works in the following way:

  • The first stage is that of mechanical filtration where the filter has 0.1 to 0.3-micron pores and the water is passed through it. At this point, contaminants such as rust, sediments, large bacteria and parasites, and other impurities are removed.
  • The second stage deals with the water-softening process. Here, ion exchange takes place that removes calcium and magnesium to make the water soft. Also, toxins and heavy metals are removed.
  • The third stage involves activated carbon filtration. This may be the most important stage of filtration where organic contaminants such as pesticides, herbicides, disinfectants, and chlorine are removed from the water.
  • The fourth stage is an optional one where alkalization takes place. Here, the use of infrared rays makes the water more alkaline by ionizing the acidic elements of water.
  • The fifth stage is also an optional one where KDF filtration is done. Elements such as iron, mercury, lead, chlorine and hydrogen sulfide are neutralized and reduced by the KDF filter.
  • The sixth stage, again an optional one, consists of a silver filter. Whatever bacteria, viruses, toxins, and heavy metals that are still left in water are removed with the help of a silver filter.
  • The last stage of remineralization, though optional, is quite effective for your health. Here, a remineralization cartridge, that releases calcium and magnesium ions, makes the water healthier for you to drink.

Do You Still Have Any Queries?

There are general queries that can be mind-boggling for some. So, to put your mind at ease and to help you get to know your countertop water filters, I have addressed a few questions that may be helpful in finding the right filter for your kitchen.

Can The Growth Of Bacteria Occur In A Faucet Water Filter?

Yes, the growth of bacteria does occur in a faucet filter as confirmed by a study conducted by Nancy Love that examined the growth of bacteria in activated carbon filters. It was published in the journal Environmental Science: Water Research & Technology. You need to maintain your filters, replace filter cartridges regularly, and flush water for 20 seconds before turning on the filter and for another 5 to 10 seconds after turning on the filter.

How Will You Determine When To Change The Filter? Taste Or Water Flow Rate Can Be Helpful?

Surely not. You just need to follow the instructions provided by the manufacturer on when to change the filters.

Is A Big Countertop Needed For A Countertop Water Filter?

Of course not! The latest countertop water filters are quite space-efficient and can be placed anywhere near your sink without becoming a hindrance in your workplace.
