Before we discuss the top countertop filtration systems in the market, let us take a look at the systems available in the market.

Common Types Of Countertop Water Filters


Filter dispensers are portable and very effective. They are also cheaper in the long run and do not need electricity for them to function. The dispenser can be used by small and large households.

A filter dispenser is made up of an upper and the lower chamber or the container. Its filter elements are  in the middle. The upper tank is filled with water, allowing to run through the filter. Once it reaches the lower chamber, the water is purified. It normally takes a couple of hours to complete the process.

A filter dispenser is not connected to anything. It has no power plug, water line, or faucet. This equipment can be placed on an office table, kitchen counter, or inside your car if you go on a road trip.

But, you have to fill it up after a couple of days. Using a pullout faucet allows you to easily reload the tank.


A water distiller is best used when you are looking for extreme purity.

This equipment can boil water, rum the steam through its coils, before changing the steam into pure water in its container. All contaminants, including heavy metals, sediments, and most chemicals, are removed. They are condensed and removed.

But, not all water distillers are the same. Some offer medical-grade water with a refreshing and sweet taste. There are others with a slight smell after it goes through the whole distillation process. The machine you will get depends on the quality of the materials of the machine. Since heat is involved in the process, it’s best to avoid machines made of plastic.

Water distillers are normally small and can only process a couple of gallons. These machines are ideal for a household with two or three people. Since it takes hours to finish the process, you may want to consider other options if you have the tendency to be forgetful.


Water ionizers are advanced and costlier water processors. They are basically the Rolls Royce of water processors.

Ionizers use electrolysis in processing water. It gathers the positive ions in water through its negative electrodes to make cathodic water. On the other hand, negative ions are gathered to create anodic water or oxidized water.

The high alkalinity and anti-oxidating potential give cathodic water its sweet taste. But, it also increases the pH in blood. This reduces risks of some diseases, including allergies, skin irritations, and even cancer.

The effect of a water ionizer is still being discussed. But, tap water that goes through the machine smells and tastes better. The pre-filters of the machine may have something to do with this.

Water ionizers are designed for people who want water that is good for their health. These people also have money to spend.


Reverse osmosis filtration systems are among the most effective filtration systems in the market. They can handle nearly all types of water pollutants. These pollutants include chemicals, sediments, and heavy metals.

This system normally comes with pre-filtration materials in cartridges and a tank. They are also big and are normally installed in cabinets under a sink. But, recently countertop machines have started to become popular due to its simple installation and appealing design.

These systems are ideal for kitchens with suitable countertops. They are also useful for households where there is a high risk for heavy metals in water. These include houses with old pipelines and hard water areas.


Sink-top filters are the best options when it comes to space, budget, and time.

The filter is not intrusive compared to the other water processors. It can be placed right beside the faucet without obstructing the sink. The filtration process is also fast even with moderate water pressure.

One drawback is the lifespan of its filter. It can last several months, but replacing it only takes a few minutes. This is the reason it is preferred by people living in a rented home. It is also popular for people who want a fast and easy solution to remove the smell of chlorine coming out of the tap.
