A countertop water filter is a small device that connects to the faucet and filters your water at the point of use. It is installed in your kitchen and can be used to filter all the drinking and cooking water in the house.
Countertop water filters are great for people who want to get healthier without investing too much or giving up their favorite drink. Countertop water filters are not expensive, they just need to be replaced every few months depending on how much you use it.
Choosing a countertop water filter that will meet your needs requires a bit of homework. According to Consumer Report, the first step in determining which type of water filtration system to choose is to determine what is in the water.
Each community provides a consumer confidence report, or CCR, which lists all contaminants found in your water. Find out what’s in your tap water here.
Next, there are different types of countertop water filters, but if you simply follow these 4 guidelines below, you’ll easily pinpoint the right system. The systems available vary in terms of Price, Filtering Technology, Filter Media, and Micron Rating.
In terms of price, there are countertop water filters which have lower initial cost but require frequent replacement. The best buy, are the countertop water filters which are high quality systems and only need replacing about every 6 months or should be able to filter around 10,000 gallons.
2. Filtering technology
Most countertop water filters are often a multi-stage or double-stage filter. More is not always better, but more sounds better. The larger the surface area, the longer the contact time of the water and the more effectively the contaminants are eliminated.
More steps also make it possible to remove larger particles first and get a more efficient and durable filter.
Some countertop water filters are limited to a small number of filter media. And one of the two steps can be nothing more than a thin screen that provides low-quality contaminant reduction.
3. Filter media
Filter media include;
- Activated carbon filters
- Reverse osmosis filters
- Ion exchange
Activated Carbon filters treat chlorine residues and other odor issues as well as overall taste. Contaminants adhere or adsorb to the surface of carbon particulates as they pass through the filter.
The activated carbon filter is the best solution to eliminate radon, pesticide residues and other specific organic chemicals.
Reverse osmosis technology uses pressure to force water against a fine semi-permeable membrane that rejects most contaminants and leaves only single molecules through. The oxygen also flows through and it saves the water of the dead taste.
Ion exchange eliminates contaminants and naturally balances the necessary pH levels to prevent disease.
Once the water passes through the filtration system, it goes into an ionization chamber where positively charged ions attract harmful bacteria, algae, viruses and debris.
More specifically, these ions attack and deactivate the life support system of bacteria and algae cells, destroy any viral nucleus, and filter out colloid debris causing cloudy water. The ion-exchange process produces pure, healthy and balanced ionized water.
4. Micron rating
A high-quality system should be NSF certified or should be certified by a credible laboratory. The very best systems will have sub-micron filtration. This means that it will filter out contaminants that are greater than 1 micron in size.
This level of filtration for a countertop water filter is so effective that it is able to remove microbial organisms like cyst parasites, such as giardia and Cryptosporidium.
We have compiled all the information available on the 10 most effective countertop water filter systems on the market. These systems have been tested and certified by NSF to filter drinking water and cooking water to be wholesome, clean and odorless.
Each manufacturer’s product is offered in an affordable price range and what you will pay for a countertop water filter won’t touch even what you spend in a year on bottled water.

Countertop Water Filters Buying Guide
Whether you are an American or live in Canada or any other part of the world, a countertop water filter review appears to have little to offer regarding the things that concern you. In a broad general sense, most of the reviews fall short of being informative.
Here’s what some of the best review websites had to say about some water filter pitchers:
- they produce good tasting water
- the pitcher can be stored in the refrigerator
- the filter pitcher should be regularly replaced
However, what should be most of concern to you is the level of effectiveness these water filters have in filtering your drinking water.
The only way to do this is to read the performance data and compare individual brands, but this can be time-consuming. Besides, you also need to consider that various filtration machines are made for different purposes according to the source of your water, so you need to know what you should go for.
Not to get worried, we have done much detailed information on what you should look for whenever you want to buy a countertop water filter. Read on to find out more:
- Your Water-Source
Is it from a reservoir or well? I don’t want to put you off completely, as any type of water filtration system has to be better than none, especially as the water running through your pipes can pick up many toxic substances on the way to your tap. But these include: farm waste, sediment, pesticides, industrial chemicals and heavy metals.
Each source has unique contaminants and different appliances will be needed accordingly. Reading some of the market reviews gave us some insight into this product; a good countertop water filter should have these qualities.
- Tested under more challenging conditions to determine the impact of claims i.e. lead reduction efficiency, the system was tested at a level 10% higher (155-160) than the certification requirement of 150 parts per billion based on a 500-gallon test cycle.
- Tested under real-life conditions by adding challenged chemicals to regular chlorinated tap water.
- Replacement filters
Replacement filters are a necessity for a constant supply of fresh drinking water. How often will you have to replace yours and how much will it cost; if you consider a comparison with other water filters.
The most important thing that is available with some countertop water filter is an automatic monitor gauge which tells the user the time for replacing filters. Also important point is to consider if the countertop water filter cartridge is recyclable. These recycled cartridges are also required to undergo a quality test before they are retailed.
- Does The Appliance De-Mineralize The Water?
The health benefits of getting rid of chlorine and other chemicals from your drinking water are obvious and it’s recommended by many health professionals. But if it strips away the potassium, calcium, and magnesium which are much needed to keep your body healthy, and then you will need to think twice. This applies to reverse osmosis and distillation systems.
Nonetheless, does this go far enough? I don’t think so. Let’s look at the final quality of a good countertop water filter.
- Advanced filtration technology
An advanced filter technology cuts the taste and odor of chlorine to deliver great-tasting water.
The bad taste and odor in tap water are usually caused by chlorine and other minute particles in water. An advanced filtration cartridge helps remove them to undetectable levels. It is also quite useful in removing heavy metals like copper and lead from water.
Drinking clean water is essential for general health and it also good in improving our cognitive function and brain performance. It improves energy levels and bodily functions. Filtered water is the best beverage for your body, your skin, and your organs. Pure water is great for your complexion, helps you lose weight, and keeps you energetic and young.
The cost of a countertop water filter is much higher than the bottled but the performance is worth the extra expense. The only drawback of a countertop water filter over bottled water is the reduced pressure.
You should consider a countertop water filter to enjoy clean water every day. The elegant design of these filtering systems offers a perfect blend of reliability, affordability, and quality and is a perfect addition to your kitchen sink.
