How To Choose A Countertop Water Filter

New Wave Enviro CounterTop Water Filter

Water contamination is getting worst these days across the country. In recent days, there are tonnes of news regarding unsatisfactory water conditions and deteriorate water quality.

To overcome this issue, we need to have an additional filtration system for our drinking water before we consume it. Whatever that wasn’t filtered, will be filtered by you. 

Picking a water filter can sometimes be a hassle. You don’t really know which water filter is the best in the market. Well, sometimes the best isn’t right for you.

Here are some guidelines for selecting the right water filter.

Identify The Contaminants in Your Water Source

The most important element of buying a water filter is to remove contaminants that exist in our source water. Do you know what are pollutants exist in your source water? One method is to look for your local Consumer Confidence Report. You should be receiving it on July 1st of every year.

Search For The Model That Removes The Contaminants 

Search for several filters which filter the contaminants that you identify earlier. Do not settle for just one system. It will be a great determining factor if the system has an NSF or WQA certifications although it isn’t required.

Besides removing the contaminants that you identify, it is always good that it will get rid of some other major contaminants such as chlorine, arsenic, mercury, and lead.

These contaminants are deadly and should be removed for you and your family’s health.

Initial and Running Investment

Is this filtration system falls within your budget? Some systems might be affordable at the initial cost but the filter replacement cost per year is twice as much as the initial cost. Never forget to check on the running cost.

Installation Process

While some gravity-driven water filter doesn’t require installation, generally this type of water filter only required minimum installation. You just need to be sure that your faucet fits the adapter of the filter that you intend to purchase.

Read the Reviews

If you purchase from Amazon, you can definitely return it within 30 days if the product doesn’t meet your expectation. It’s good to go through the reviews by existing customers so that you won’t be wasting your time on bad products.

It is certainly not a hard rule to follow the guideline above in order to own a countertop filtration system. It is just a recommendation.

Big Berkey Filter – Popular Pick Countertop Water Filter

review of Big Berkey Water Filter

Berkey is one of the top gravity-fed water filters that are available in the market. Sadly that it is not available in Iowa and California due to the banned imposed by the two states.

After a thorough understanding of the situation, we think that the banned is due to some regulatory request by the state which was unable to fulfill by Berkey due to hefty cost.

We believe that it is still a great piece of water filter which shouldn’t be missed. Let’s dive deep into the Berkey system and understand why we think that it is that great.

Great Quality Filter: The foundation of Berkey systems is made up of two separate cartridges, the Black Berkey and the Fluoride Filter.

Black Berkey and Fluoride Filter

Black Berkey: It is a microporous filter, which removes up to 99.9% of some of the contaminants that appear in the water.

It was independently tested in the EPA-approved laboratory against NSF/ANSI Standards 53 to ensure the quality of the filter is being achieved.

The Black Berkey is easily cleanable from time to time when the flow rate started to get low. This can prolong the lifespan of the cartridge.

Fluoride Filter: Although it is named a fluoride filter, it can do better than just removing fluoride.

Besides fluoride, this system is able to remove Arsenic, which is one of the dangerous contaminants available in our water source. Apart from Arsenic, it removes MBTE and some other heavy metal ions.

With the combination of Black Berkey and Fluoride Filter, Berkey is capable of filtering the list of top 20 major contaminations shown below.

Berkey Contamination List

For a more in-depth list of contamination that is filtered by Berkey, kindly refer to this list.

Besides the chemical contaminants, their filter also removes 100% of pathogenic bacteria. Generally, it is required to have a UV light sterilizer to remove the bacteria.

Variants And Sizes: There are different models of Berkey to cater to different needs. Take Berkey Go as an example, it is designed for hiking and traveling purposes with its small and compact size.

While the Crown Berkey is suitable for small offices or huge household as it container can store up to 6 gallons of water at a time.

Berkey Water Filter Models and Size

One of the best sellers is the Big Berkey, which is having an ideal size of 2.25 Gallons that is enough for a decent size family of 4.

Replacement Cost: A pair of Black Berkey can withstand up to 6000 Gallons of water as suggested by Berkey. This is mainly due to the cartridge is cleanable

The Fluoride Filter is small in size. Hence, the lifespan is just about 1000 Gallons per pair or approximately 2 years for one set of replacements.

Annual Replacement Cost: $80

Lifetime Warranty: When you register your Berkey, you will receive a Berkey Care Lifetime Warranty instead of the standard 6 months warranty. However, this only applies to Travel, Royal, Big, Imperial, and Crown Berkey.

Bottom line: It is great to see how Berkey can build such a simple filtration system while still capable of removing so many contaminants. Although the flow rate might be lower compared to the rest of the system, it is a great system that you will never regret.

+ Portable and doesn’t have any tubing or adapters.
+ Great filtration capability in removing contaminants.
+ Long Lifespan Filters.
Flow Rate is lower compared to the pressure-fed filter.
Expensive on the initial investment.

What Is A Countertop Water Filter?

From the name, you probably have guessed that this type of filter normally sits on top of the kitchen counter. In order to blend in seamlessly with your kitchen, most of the filters are well designed and have a sleek appearance.

The companies that produce such water filters tend to be more innovative. Due to the space restriction, they are forced to pack the filtration media into a single canister. Otherwise, they will need to justify a good-looking casing to enclose it.

Types Of Countertop Water Filters

Countertop water filters have slowly found their popularity in American homes due to the rising need for safe water. They are relatively cheaper compared to under sink water filters and easy installation.

Here are the five most popular types of countertop water filters you will find in the market today. 

Water Distiller

A water distiller boils up your water, takes the steam through condenser coils, and back to pure liquid in a container collector. Water distillation is one of the oldest and effective methods for removing contaminants. 

This type of countertop filter ensures that all the contaminants, including heavy metals, sediments, and chemical contaminants, are being removed. 

Water distillers are suitable for households with 2-3 members or individuals because the whole process takes time. 

Do consider where to put your water distiller as this distiller required electricity. 

Water Ionizers

Water ionizers have a slight functionality compared to other types of countertop water filtration systems. They have pre-filters to remove water contaminants like other filters, but the primary purpose is to ionize the filtered water. 

Ionizers use the electrolysis process to change the pH of water. Depending on the settings, the electrolysis plates will attract ions to make the filtered water acidic or alkaline. 

For alkaline water were produces, it has a lower ORP, which is an anti-oxidizing agent that helps to neutralize the harmful free radicals on our body. 

Water ionizers are generally more expensive than other water filters due to their advanced technology. However, it is worth every penny. 

Gravity Fed Filter

This type of countertop drinking water filter is portable and suitable for families of all sizes.

Typically, this system doesn’t depend on electricity but relies on gravity for water filtration. It generally includes an upper and a lower chamber, with filtration elements in the middle. 

Water flows from the upper tank then gets through the filters to the lower chamber (container), filtered. These water filters don’t need any power plug connection, faucet connection, or water line. 

The main drawback is the filtration process is slow. 

water filter on the counter

Reverse Osmosis

This type of filtration system works when there is a semi-permeable membrane incorporated into the system. It is called the reverse osmosis membrane. 

The RO membrane is capable of removing up to 99% contaminants in the water with a 0.0001-micron rating. Tap water is forced through the membrane leaving behind the contaminants. 

The reverse osmosis filters also remove beneficial minerals such as calcium and magnesium. However, there are many systems out in the market that will remineralize the filtered water with natural stones. 

Faucet-Mounted Filter

Of all countertop water filters mentioned above, sink-top faucet-mounted water filters are the oldest among all. They often come with one canister filter that does everything. 

Installation is made directly into your kitchen faucet and filters water immediately before it comes out through the tap. The filter cartridge is usually small-sized and fits nicely next to the sink. 

Filter longevity and capability are the downsides of this type of filter. Due to its size, a replacement is required every 3-6 months. However, there are still some excellent systems out there in the market. 

Benefits Of Countertop Water Filters

What are the benefits for using countertop water filters?

+ Minimal Installation: You will either require no installation procedure with a countertop drinking water filter or connect it to your kitchen faucet and get going. Gravity water filters, especially, have minimal to no installation difficulties, so you can carry them along with you anywhere you go. 


+ No Extra Faucet: Unlike under sink water filters, countertop filters don’t require an additional kitchen faucet on the sink. The faucet adaptor helps to switch between regular and filtered water from your tap.  

There’s no drilling of holes and a complicated installation process. 

+ Cheap Maintenance: It’s cheap and easy to maintain a countertop water filtration system. At no instance will you need to crawl under your sink to fix a problem with the pipes. All you need is to clean the filters and replace them within the required time intervals. Plus, you don’t need to dismantle half the system while changing the filter cartridges. 

+ Portability: Since there are no complicated installations on the system, these filters are incredibly portable. You can easily unscrew the faucet adaptor in under a minute and move it to a new location. 

Drawbacks Of Countertop Filtration Systems

What are the drawbacks of using a countertop drinking water filter?

– Single point filtration: The point of filtration for countertop water filters is only on the tap in which they are installed. It is primarily for drinking water, unlike whole house filters that filter all the water that’s entering your home. 

– Aesthetic Reasons: Some filters might not blend in well with the design concept of your kitchen. Unlike under sink filters, they sit on top of your kitchen sink.  

– Efficiency: Compared to multi-stage water filters, some countertop water filters lack the same contaminant removal capacity.

Who Should Use The Countertop Water Filter System?

Countertop water filters are often portable and can be easily detached from one place to another. This guide is great for people:

  • who is looking for a switch from faucet filter or water pitcher.
  • who stayed in a place where city water is their source water. 
  • who are looking for affordable options for filtering your drinking water.
  • who are renting an apartment which cannot be involved in heavy installation.

The main reason for these recommendations is due to it does not require a complicated installation procedure which involves drilling.

Generally, due to the small size and portability, it couldn’t pack a complicated filtration system in one canister filter. Hence, it won’t work well on a highly contaminated well water source. (Except for the RO water filter)

How Do You Install A Countertop Water Filtration System?

Follow the simple steps outlined below to install your new countertop drinking water filter:

  • First, you need to place your water filter in a strategic position, where you can get enough line length to connect to your faucet adaptor.
  • Locate the faucet where you are installing the filter, and remove its aerator. Define what type of thread your faucet has. If it’s an outside thread, you don’t require an adapter.
  • If it’s an inside thread, choose the right adapter and washer and screw into the faucet. Tighten using hands.

Note that each countertop drinking water filter comes with an adapter. These mostly fit into any faucet, apart from non-standard or customized adapters.

  • Attach your diverter valve to the faucet and turn the swivel collar for tightening. Ensure that the gasket in the diverter is correctly positioned between the drain and the valve. You might need to retighten the swivel collar later.
  • The last step is to turn on the water and allow water to flow through the faucet normally.

To allow water to flow through the filter, turn on the diverter handle. Turn the diverter handle off to stop the water flow, or turn off the faucet knob.

Wrap Up

Based on the 10 best countertop water filters that we recommend, which one suits your house? Or you are still looking for a greater system?

If you are a homeowner, we do suggest that you go for one of the best home reverse osmosis systems. It has more features and capability in removing contaminants in rigorous conditions.
