In the first stage, water goes through a sediment filter that extracts particles like rust, sand, dust and dirt out of the water. In the second stage, it moves across a carbon filter that helps in eradicating contaminants like chlorine, harmful chemical substances and compounds which create an unpleasant smell in the water. The third stage is very important as it includes the reverse osmosis membrane process wherein the most harmful contaminants like chromium, fluoride, lead, TDS, arsenic and radium are removed.

Buying Guide: Best Countertop Water Filters

Because of the convenience they offer, countertop water filters are fast becoming the recommended choice for water filters. There are a lot of products to choose from – some are worth it while the others are not.

In this section of the article, we’ll take a look at the factors to consider when buying a countertop water filter. When you’re done reading this buying guide, you’ll be able to make the right choice that’ll suit your needs and that of your family. We also recommend looking at some faucet water filters if you plan on putting this in your kitchen.

Type Of Countertop Water Filters

There are two different types of countertop water filters.

1. Water Filter Pitchers: This refers to the jug-like water container that comes with its own filters and filters the water entering it. Some are designed to filter the water as it leaves. Water filter pitchers are compact-sized and can hold at most 25 cups of water (8 oz. standard).
2. Conventional Countertop Water Filters: This type of water filter comes in two different variants; a tank model or the tankless model. As the name implies, the tank models come with their own tanks which can hold a limited amount of water. On the other hand, the tankless models are directly connected to the water source. This is where the faucet water filter falls under.

A lot of individuals classify the faucet water filter as a countertop water filter. Well, here at Water Filter IQ, we know better which is why we didn’t include it. If you’re interested in owning a faucet water filter, here’s our review on it.

Having decided which type to buy, you should also consider the following.

Size

You should take note of the amount of space you have left on your countertop if you’re interested in getting the models with a tank. This will help you to plan accordingly and leave ample space for other things on your countertop.

Size can really be a deal breaker if you don’t take it seriously.

Capacity

Getting a tank model? What’s the capacity? How often do you use it? How many persons will be using it? These are some of the important questions you need to ask with regards to capacity.

The larger the household, the larger the size of the unit you’ll need.

Filter lifespan

At this juncture, we expect that you’ve seen a handful of units you’re interested in. Now, take a look at their filter lifespan and compare. Opt for models with higher filter lifespan.

In addition to that, getting a replacement filter shouldn’t be as difficult as finding an eagle’s egg. We recommend buying the replacement filters in bulk to ensure that you don’t run out of filters – and you’ll get to save money too.

Contaminants you want to remove

Knowing the contaminants in your water can go a long way in helping you select the perfect water filter. If your water is directly sourced from the city, a trip to the municipality office will furnish you with the list of contaminants in your water.

Most manufacturers indicate the type of contaminants their products can remove. Crosscheck with your list to see if the contaminants in your water can be removed by the countertop water filter or simply measure the drop in Total Dissolved Solids (TDS).

Installation

Although most countertop water filters don’t require installation e.g. the water filter pitcher, the ones that do should be done by either a professional or a DIY enthusiast who has experience in such installations.

This will ensure that the product isn’t damaged and will prevent the warranty from being voided.

Look out for certifications

Certifications help to build consumer confidence in products. Look out for certifications for the filter as well as the water filter in general.

Frequently Asked Questions About Best Countertop Water Filter

1) What are countertop water filters?

A countertop water filter is one that has an elongated spout which can be installed beside the kitchen sink. It is also referred to as a point-of-use filtration system as it can be set up anywhere you need to have access to clean water. These filters are made with the primary goal of removing the impurities that are found in untreated water coming from different sources so that the water can become safe and hygienic enough for consumption. It can be connected directly to a faucet. Water coming out of the faucet can be poured directly into a cup or a glass and be used for drinking purposes.   

2) What are the different types of countertop water filters?

Countertop water filters are available in different types. Some of these are listed below.

a) Carbon Filters

This is the kind of filter you need if you are particular about the taste of the water you drink. It eliminates odor and lends a pleasant taste or flavor to the water. Municipal water plants utilize chemical substances like chlorine and chloramine and water which is sourced out from these plants, invariably, contains these elements. The carbon filter has been designed to eradicate these substances from the water. Apart from volatile organic compounds, the carbon filters are good at eradicating herbicides and pesticides. They follow a process called adsorption to reduce the number of contaminants in the water. When natural compounds come closer to carbon, they get attached to it. When water goes through the filter, the contaminants stick to the exterior surface of the carbon. That results in the foul smell or odor going away from the water. 

b) Ceramic Filters

If you are concerned over the presence of bacterial content or microbiological organisms in the water, you should opt for a ceramic filter. It uses an infinite number of microscopic pores to extract bacteria and sediments from the water. The porous surface has a micron rating ranging from 0.7-0.5 microns. A bacteria’s size is around one micron and therefore, would not be able to pass through the ceramic casing. The ceramic casing is infused with silver, a material that prevents the growth of microorganisms on the exterior of the filter. Ceramic is an organic filter and can be washed and used multiple times. The durability of ceramic filters makes them very popular. 

c) Water Distillers

The process of water distillation is very similar to the traditional methods people adopted to purify water. Water evaporates from natural sources like lakes and oceans due to heat and gets condensed in the outer atmosphere. It precipitates and returns to earth in the form of dew or rain. A water distiller boils water till a point it turns into steam. It then condenses, cools it down and produces it in liquid form. This is one of the most organic methods of purifying water by a water filter. 

3) What are the things I need to do before buying a countertop water filter?

Buying a countertop water filter or any product for that matter, requires careful planning. Since you will be paying for it, you have to set aside a budget. Once you do that, you will look for products only in that price range. It will also prevent you from spending more than you intend to. Then, you need to test the water you get at your home with a water test kit. By doing this, you will get to know the kind of contaminants present in your water. For instance, if your water supply has a high amount of chlorine content in it, you must get a countertop water filter that is known to be efficient at dealing with it.

 It is important to spend some time doing research on the contaminants as it will give you a good idea about the health of your water. Once you are done with this, go through different brands and models online. You will get enough information about the product from their official website or even from the site which has put them up on sale. Once you are sure that a particular product will meet your requirements, go for it. 

Conclusion: Best Countertop Water Filters

Countertop water filters take up minimal space, are mostly portable, and do a good job of purifying the water even when they get limited water pressure. The best part is that you have the freedom to set them up in an area where you actually need fresh and hygienic water. They use a variety of filters to ensure that the water coming out of your taps is devoid of impurities and fit for consumption. There are various types and models to choose from. While most of them are beneficial in some way or the other, look around for a while and settle for the one that you feel would fulfill your needs and expectations best.
