Big Berkey portable water filter is the answer to the regular contaminated tap water that is filled with different chemicals and toxins like Prohormones, pesticides, bacteria, heavy metals, etc.

It uses gravity to force the water through the cartridge, removing pathogens and above mentioned toxic elements with close to 100% purification efficiency.

Why choose big Berkey – Benefits

It is No#1 on our Best countertop water filter list due to the following reasons:

  • This model is affordable with 99% filtering efficiency.
  • It works on four purification elements. Two Berkey black filters, and two fluoride filters.
  • An average household of 2 – 4 people uses about 2 – 4 gallons a day, and Big Berkey provides an actual 6000 thousand gallon capacity which is more than the actual requirement.
  • You have about four years with one load of these filters.
  • It would be a stressor if you had to constantly replace the filters, but since you don’t, you can get clean water regularly.
  • No electricity, tools, and plumbing services are required.
  • You don’t even need to attach it to your kitchen faucet (portable).
  • Bring it to any picnic spot, and use the pond water. It will take out 99% of the toxins in the water.
  • It is one of the cheapest water filters in the market.

Berkey purification filter elements: Berkey filters can clean out 99.99% of the toxins and they work on three different levels to filter out:

  • viruses
  • pathogenic bacteria
  • heavy metals including arsenic, lead, mercury, and chromium
  • pesticides
  • Prohormones
  • Protozoa
  • Inorganic minerals
  • Pharmaceutical drugs, etc.

These filters are made of carbon composite containing high-grade coconut shell carbon combines with 5 different types of media which allow to filter everything out (foreign substance).

Both filters will give 6000 gallons before being replaced. This capacity can be increased in areas where the quality of the water supply or groundwater is not that bad.

The technology used in Berkey Filters:

  • There are millions of pores in filters. The first path that toxins have to go through are these small countless pores.
  • Just that first defensive layer makes it extremely difficult for toxins to pass through.
  • Then adsorption and absorption technology are being used by the filters to create an ion barrier. The ionically charged barriers will filter the remaining heavy metals and minerals.
  • In simple words, the ionic barrier will pull the metals just like a magnet.

The two extra filters will help to filter out fluoride:

Nobody likes to drink water rich in fluoride, it is not good for health. The two extra white-looking filters help to makes sure you get all the fluoride out from your drinking water. Both filters last about a year.

Why Big Berkey is durable:

This model is 100% plastic-free and made of 304 stainless steel. The 304 steel has excellent corrosion resistance and heat-resistant properties. That is why this water filter is among the best countertop water filters in terms of durability.

Big Berkey water filter is precisely designed to stay intact so that it would be a primary choice for road trippers and campers. It won’t leak or break under the shocks of mountainous roads. I would recommend this model to travelers.

  • Super budget-friendly
  • Highly durable and long-lasting
  • True 99.99% toxins removal capability
  • Purification filters can last up to 4 years
  • 6000 gallons per pair of filters
  • Suitable for water supply, well water, and groundwater.
  • Comes in different sizes
  • Sturdy stainless steel container
  • Portable
  • A lot of users detect a rubbery smell from the water at first.


Health professionals will always advise you about drinking more water, but they don’t mention most water sources has either chlorine, fluoride, heavy metals, or prohormones and pathogens.

Quality of the purification filters of big Berkey filters out almost all of the toxins found in the water. This model is constructed from stainless steel which means, chances of scaling are almost zero.

I can’t emphasize enough how good Big Berkey is in a normal household, but it has proven its worth on camping sites as well. I am recommending this gravity-fed best countertop water filter system.

Buying Guide for the Best Countertop Water filter

According to WHO, contaminated water can transmit diseases such as diarrhea, cholera, dysentery, polio, and typhoid. Each year, more than 485000 people suffer diarrheal deaths.

Water filters are not just the everyday products that you order online. This appliance is related to your health. So proper research is more than important. Especially for a countertop water filter.

Before making a purchasing decision, make a list of the following things:

  • Take the PH test of your existing water
  • TDS value of your existing tap water
  • How much chlorine and fluoride do you need.
  • What contaminants you need to remove from your water
  • Contact your local health department to determine what must is, and what is not in drinkable water.

After that, read our product reviews, and this buying guide carefully to detect the best countertop water filter for your family.

Our buying guide is based on data, actual information, and several other considerations to make sure you guys purchase an affordable, durable, highly efficient, and result-oriented countertop water filter.

Let’s dive in:

  • The material used in the manufacturing of a countertop water filter

Construction material defines the longevity, durability, and purity of the water. Most countertop water filters use plastic in their construction which will likely leak BPA materials.

Bisphenol A (BPA) is directly related to high blood pressure, diabetes, and obesity. It is smart to avoid filters using plastic that leaks BPA materials.

I would recommend stainless steel which is durable, strong, and resistant to corrosion. It does not interact with water’s properties and is prone to breaking. BIG Berkey & ESOW countertop water filters using high-grade stainless steel in their construction.

Ceramic is also recommended. It is also durable and prone to heat, rusting, and scaling.

  • Evaluate your household need:

I recommend that you should evaluate the water requirements of your house. Every family has different water purification needs. Some like more alkaline water, some need more minerals while others don’t.

Check your municipal tap water. Not only heavy metals are a big problem in tap waters, but bacteria, pathogens, herbicides, strong odor, chlorine, and viruses are common in water supplies.

It is much easier to select a countertop water filter after you know which minerals you want your filter to retain, how much alkalinity do you need, and which contaminants do you want to get rid of.

Most of the units in our reviews retain beneficial minerals while removing lead, chlorine, bad taste and odor, arsenic, heavy metals, herbicides, pesticides, and other particulates.

Some models like APEX are known for their alkaline filtered water which is preferred by many households, but not everyone likes it. That is why I am emphasizing that should evaluate your home’s purification needs.

  • Lifespan and replacement of filter

Even the best countertop water filter needs filter replacement. It is necessary to check the lifespan and replacement cost of the filter.

Different models have different replacement costs and lifespans. For example, the Cleanwater4less Countertop Water Filtration System needs no filter replacement. It will last up to 10000 gallons before needing a new one.

Other models like Aquasana & APEX are budget-friendly but their filter lifespan is 6 – 10 months with low replacement cost.

Many countertop models in the market are just a pain in the ass. Their filter needs regular maintenance and quick replacement.

Always check the filter replacement cost and the lifespan. Many budget-friendly models are giving excellent filter lifespan with minimum maintenance.

Check out all the products in our best countertop water filter reviews. You will find one that suits your pocket.

  • Contaminant filtration capability:

Some filters are efficient enough to filter all kinds of contaminants including chlorine, arsenic, and lead. Others are more targeted towards specific toxins.

While choosing a water filter, check if the filter is capable enough of removing:

  • Chlorine
  • Arsenic
  • Lead
  • Heavy metals
  • Herbicides
  • Pesticides
  • Pathogens
  • Bacteria
  • Suspended solids
  • Particulate matter and more.

The main purpose of a water filter is to provide contaminant-free clean water. Don’t compromise if the filter is not good enough.

Such filters are not only limited to expensive models like Big Berkey, other budget-friendly countertop water filters are in our reviews are also capable of removing above mentioned contaminants with more than 95% efficiency.

  • Economical:

The more complex a countertop water filter is, the more expensive it will be. There are many factors upon which cost is defined such as:

  • Which type of material is being used
  • The efficiency of the filtration
  • Stages of the filtration process
  • Flow rate.
  • Filter’s lifespan
  • Can we use the countertop filter for well and pond water too, or not.
  • The durability of the product
  • Size of the product.

Make a checklist of all the above factors before making a purchasing decision. Most countertop filters are not efficient in their work, but in the end, it all depends upon your budget.

We have dug up some of the best countertop water filters that are practically flawless in their work, durable under stress, will provide more than 90% filtration efficiency with low replacement cost (most of them).

And the good news is,

Not all of them are expensive. If you can afford it, then Big Berkey & Apex counter top filters should be your choice because both of these units are durable, highly efficient in their work.

There are other budget-friendly options like ESOW & Brondell which will also provide clean and delicious water to the family of 2 – 4.

  • Compact and space-saving:

One of the main purposes of a countertop water filter is to save space and sits perfectly beside your sink.

Most countertop water filters are sleek and lightweight, but some models are bulky in their appearance.

I would recommend going for a portable, lightweight, and sleek model like Apex, Brondell, Aquasana, and Big Berkey. You can carry these units anywhere from camping to small apartments.

  • Filtered water taste and odor:

I want my water to be delicious and free from bad odor. Different people have different choices in terms of water taste, but no one wants bad odor.

Read the reviews carefully to know if the unit is releasing a bitter taste in the end or sweet delicious water. Whatever happens, never choose a unit whose filtered water smells like hell. It is my humble advice.

People also complain about the rubbery smell in the water caused by rubber washers that fit over the diverter valve. It has nothing to do with the filtration process. Replace the rubber washer with a silicon washer. You will not smell that rubber again.

How easy it is to install a countertop water filter

Don’t worry about this step. It is easier than you think to install a countertop filter. One of the drawbacks is, most water filters only attach to standard faucets with aerators. Always check if the filter can attach to the faucets or not.

You need to remove that aerator and insert the diverter valve as per the instructions printed on the manual, and your water filter is ready to go.

No need for additional tools for plumbing. It is DIY.

Warranty and support

A 30-day return and exchange warranty is common in the water filter market. It is not bad, but I would recommend for the models that are offering limited warranties with lifetime or limited support.

Models like Brondell are offering lifetime free support with a limited warranty. It is satisfying to know that aftercare is available in case of any failure or problem.

Support is also helpful when you begin the installation. They will guide better than the manual. You can explain to them your situation like the type of sinks, faucet, tubes, and hoses you are using.

Look for the deals that are providing aftercare.
