Countertop Water Filter Buying Guide

Countertop water filters are just one of many different types of home water filtration system available. This essentially means that they might not necessarily be the right type of system for your home.

In our quest to provide you with as much value as possible, we’re going to outline several usage scenarios in addition to the type of performance you can expect, which should help you come to a conclusion as to whether or not this type of water purification filter is for you.

How Does A Counter top Water Filter Work?

​Counter top ​systems are designed to sit atop your kitchen counter and takes its water supply from your sink. For this reason, there should be a reasonable amount of available space surrounding your sink so that you have a suitable permanent location for the placement of your water filter. Unlike other forms of water filter, most counter top models do not employ reverse osmosis water technology (similar to the ion exchange process used in household water softeners).

Installation and Use

As mentioned, this type of water dispenser takes its water supply directly from your kitchen sink. It does this via the use of a special adapter which is placed over the spout of your kitchen faucet, redirecting some of the water flow from the faucet itself to your counter top filtration device through the attached hose.

Due to this method of installation, you will of course need to operate your faucet whenever you wish to dispense filtered water through your new counter top dispenser. Be sure to remove your faucet aerator if required.

Each counter-top water filter will have its own spout in addition to a tap or switch, providing you with complete control over how much water is dispensed each and every time. It should be noted that water is filtered only on demand, with this type of filter unable to provide a stored quantity of water for use at a later stage. If counter space around your sink is limited, we suggest considering one of the best faucet water filters as an alternative.

Water Filtration Speed

Filtering water takes time, regardless of the type of device used. ​This type of water filter is no different with a flow rate that is acceptable for dispensing your average sized glass of water or a medium sized pot.

If you wanted to fill a large pot with filtered water, this of course would take much longer. For reference, the Enviro model we’ve tested will take approximately 90 seconds to filter a gallon of water.

​Home Usage Profiles

We previously touched upon the fact that water is filtered on demand which may or may not be suitable depending on the quantity of water you consume on a daily basis or at any one time. Below we’ve provided three typical usage scenarios so that you can see where you fit.

Low Usage

We would quantify low usage as a household of two people who drink the recommended daily intake of water. In addition, households which rarely use filtered water for cooking also fit into this usage profile. If you fit into this category, the counter top water filter system is perfect for you.

Medium Usage

We would quantify medium usage as a household or family of four people, each of whom drink a steady amount of water every day in addition to regularly using filtered water to prepare meals, food and cook with. If you fit into this category, you would be the ideal candidate for such a water purification device.

High Usage

If your household consists of four or more people who constantly utilize filtered water for drinking, making beverages and cooking with, we would place you into the high-water demand category.

In these instances, we would recommend a water filter that allows you to filter and store water for use at a later date, simply from a convenience point of view.

Counter top Water Filtration Capacity

Each type of water filter is usually provided with an independent certification award, highlighting the science around the substances and compounds that are removed from your water supply.

The two most common certifications available for home water purification devices are;

  • NSF/ANSI 42: This certification relates to the removal of chlorine, iron, magnesium and other similar compounds from water.
  • NSF/ANSI 53: This certification relates to the removal of harmful substances such as arsenic, asbestos, copper, lead, mercury as well as organic and inorganic chemical compounds and bacteria.

The latter of these two standards does a more thorough job of removing unwanted contaminants and so your choice is based upon the quality of your incoming water supply. If it is safe but you simply don’t like the taste of tap water, NSF certified to the ’42’ certification standard will be sufficient.

The Advantages and Disadvantages of Countertop Water Filters

No product is without its drawbacks. Here we will provide a summary of the benefits and downsides to purchasing a countertop water filter.

Counter top Filter Pros

  • Cost. As far as water filters go, this type of filter is definitely not the most expensive option available. In fact, above counter water filters are very cost effective, even when you take into account the cost of replacement filters.
  • Low Maintenance. Simply install and go – the only maintenance required is periodic replacement of the internal filter. A much simpler process than countertop gravity filters such as Big Berkey water filters.
  • Efficiency. Whilst they aren’t the fastest water filter available, countertop water dispensers perform the task they’re required to very well and make a good compromise depending on your needs. Many homeowners find that reverse osmosis systems become redundant – especially with the use of an activated carbon filter.

Counter top Filter Cons

  • Lack of temperature control. Probably the biggest drawback for many is that above counter filters cannot chill water. If your sink water isn’t as cold as you would like it to be, neither will your freshly filtered water from any sink water filters.
  • Lack of water storage. As an on-demand filtration device, you are unable to store filtered water through the device itself, instead requiring the use of a jug or other suitable container if you wish to go down this route. It is this drawback which attracts some consumers towards filter pitchers as an alternative.

​​Tips When Shopping For A Counter top Filter

Buying a water filter should be based upon the unique needs of your household. We recommend taking the following steps before making your final decision regarding which ​table top water filter to buy.

Test Your Water Quality

Not all tap water is the same, which is why it is a good idea to gain a better understanding of the quality of your home’s water supply. Simply purchase a water testing kit which will tell you exactly what is present within your water. With this information, you can be sure that the water filter you buy adheres to the correct specification.

​Consider Mineral Requirements

Calcium, magnesium and iron amongst other minerals are usually present in all sources of water. If you have a particular need to remove any specific mineral or metal due to personal preference, be sure to check whether the filter you buy is capable of doing so.

Some consumers also like to retain some of the healthy minerals that are naturally found in water such as zinc and potassium. If this is the case, be sure to avoid purifiers that utilize a reverse osmosis system as these devices remove almost everything.

​Our Verdict

And these are our suggestions for great counter top water systems. As you can see, there are a lot of different options – bigger and more expensive gravity countertop filters (such as the Berkey water filter) , as well as smaller, cheaper and even single use systems.

We are partial to the Lake Industries Stainless Steel Water Purifier Filter because of its overall amazing quality and functionality – leading us to name it as the best countertop water filter available. The others have their benefits as well, however, so simply read each review to find the model most suitable for your home.
