What Is A Countertop Water Filter System

This is a tap water filtration system that sits on your countertop. It is a simple solution for removing chlorine and other contaminants from tap water.

The filter is connected to the faucet where water from the main water system runs through a diverter which then takes it to the inverter and then comes out of the filter faucet.

The most common design is the sink water filter which has its own faucet.The more filter units it has, the better the water quality. However, regardless of the number of filters, it will still get the job done.

Water Filter Systems For The Home: What You Need To Know

Even though the typical city water is treated and can be used straight from the tap, having an extra layer of protection by filtering it will ensure that it is safe to drink and cook with. Home water filter systems have come a long way.

In the past, people would use sand to filter out particles as the water flowed downwards. We are living at a time when we have so many options to choose from. With such an array of choices, which might be the one for you?

Why You Need A Countertop Water Filter System?

Ease of installation: Because of their very simple design, they can easily be installed without making significant changes to your main water system.

Saves you money: These water filters for home are the most affordable in the market. This type will enable you to get purified water without putting a hole in your pocket.

Easy to maintain: Once it has been installed, the countertop water filter system requires very little maintenance. You do not need to keep changing the cartridges. Once it’s installed, you are good to go.

Saves you space: Because of their compact design, these types of water filters save you space because they take up very little surface area. You, therefore, do not need to worry about it taking up precious counter space that may be used for something else.

Filter System: Carbon vs Ceramic

Carbon Filters

They are one of the oldest ways of filtering water. The contaminants stick to the filter because they are attracted to it at a molecular level. Water filtration systems that use carbon are very effective at removing chlorine but do not remove heavy metals and cysts.

Ceramic Water Filters

This is a relatively inexpensive water filter system that removes contaminants such as bacteria by use of pores that are in the filter. Water passes through the tiny pores and anything larger than the pores does not pass. The advantage of this method is that it has a long shelf life and you do not need to replace the filter every year.

In the end, it’s your choice between ceramic and carbon filters.

Types Of Home Water Filter Systems

Reverse Osmosis (RO) Filter

A reverse osmosis filter is a water filtration system that uses pressure to force water through a semipermeable membrane thus removing solids and contaminants. This system is best for homes that are using well water as it will remove dissolved salts, lead, mercury, and cysts.

The installation will require a significant amount of investment in terms of money but this method will produce the cleanest and purest water. It however does not remove chlorine from water. So, you will need at least one carbon filter to remove chlorine from water.

Water Distiller

This is a purification method where water is heated to its boiling point until it evaporates leaving contaminants like bacteria behind. Due to the heating process, the water distiller removes almost all types of contaminants such as fluorides, dissolved salts, and heavy metals from water. This method mimics how evaporated water from surface bodies behave. The sun heats the water which then evaporates and forms clouds which then fall down on earth as rain.

This is a very high-quality method of water purification and thus takes a couple of hours to produce one gallon of water. This method will however give you a better return on investment compared to other high-quality methods because it requires no lengthy installation process. The distiller is simply plugged into an electric outlet, filled with water and purification begins.

Filter Dispenser

Using a water dispenser gives you the option of using hot or cold water. The filter dispenser receives water from the tap which is then heated to 95 degrees and then passed through two carbon filters that purify it. You do not need to purify it any further as it was previously heated.

As for cold water, it will be passed through two carbon activated filtration system and a UV light chamber to make it safe for use. A filter dispenser is a great choice for anyone who is looking at reducing their waste. This is because you will significantly reduce the amount of bottled water that your family consumes.

Water Ionizer

These can usually be directly connected to your faucet or installed under your sink. The water ionizer works in two stages.

First, contaminants such as chlorine, bacteria, and other wastes are filtered out using a carbon activated filter. Then, water is passed through a chamber where electrolysis takes place resulting in reduced and oxidized water. The reduced water passes through the faucet and is very safe to use while the oxidized water is discarded in the sink.

What To Consider When Choosing A Home Water Filter System

Ease Of Installation

Most water filter systems for home are easy to install and do not need any special technical expertise. Some methods may require a deeper level of understanding compared to others. For example, a simple carbon water filter is simpler to install than a reverse osmosis water system.


The cost of purchase and installation of a water filtration system is a key consideration. Methods such as distillation and reverse osmosis will cost more compared to simple carbon filters. Investing in a water filter system may seem expensive initially, but you will end up saving in the long run.


Different water filter systems require different levels of maintenance. When deciding which to buy, you will want to think about the cost of cartridges because they eventually wear out. Your reverse osmosis system might need several cartridge changes at different times.


Countertop filtration systems may be easy to install but may not go well with your decor. If you are very particular about how different pieces tie in together in a room, you can opt for an under the sink water filter solution.

Water Quality

If the kind of water you are using contains a lot of salts such as well water, you might want to consider reverse osmosis filtration system. If you are using tap water that has already been treated, you can opt for a simple activated carbon water filtration system.

Is A Home Water Filter Worth It?

When you look at the daily cost of buying bottled water, you might consider investing in your water filter system. Bottled water is very expensive and because they are single-use plastics, they badly pollute the environment.

We all want the best for our families and a home water filter is a worthwhile investment. Using water that has excessive salts such as fluorides and heavy metals have been shown to have negative health implications in the long term. Bacteria, cysts, and protozoa can also make our family members seriously ill.

A water filter system for home is a sure bet against contaminated drinking and cooking water.
