Berkey Water Filter Buyer’s Guide

If you’re interested in buying one of these water filters, you probably have a number of questions before you make your final purchasing decision.

It’s important to know the answers to questions such as “how long do Berkey filters last?” as well as knowing about any potential Berkey water filter problems which could arise.

Here we look at the most common Berkey water purifier complaints as well as the benefits of choosing one of these water filtration systems.

An Introduction to Berkey Filter Systems

This range of water filter systems all function in an identical way, however they have subtle differences when it comes to the way in which they’re used.

Unlike other types of filter system which require connection to the house plumbing system, these units are independent, free-standing units which are placed onto the countertop of your kitchen and filled up with tap water.

The water is gravity fed through the filter with the resulting clean water being delivered via the spigot in the device’s base.

What are the Benefits?

The benefits of these water filter systems include:

  • No complex installation process is required
  • There is no need to put a hole in your expensive countertop
  • Portability
  • Easy cleaning and maintenance
  • Very clean water that is free of contaminants
  • Delicious tasting water
  • Attractive design

Are There Any Problems?

Most buyers are very happy with their filter systems however some people find it irritating to have to top up their systems manually with water.

They also sometimes find that their water filter system takes up a lot of countertop space, especially in the case of the larger models.

A further issue for some is the running costs associated with buying multiple filters for the larger models. Berkey filters are not cheap!

As mentioned earlier, the Berkey water filters have been tested by independent laboratories but have no official certification from leading bodies like the WQA and NSF International.

How do the Filters Work?

There are two filters in the Berkey range. The black filter comes supplied with every model and has to be used. There are also optional arsenic and fluoride filters.

The black filter contains a matrix of microscopic pores which microfilter the water. It removes mercury, lead and other heavy metals. Each filter lasts for around 3000 gallons of filtration use which is an impressive lifespan representing amazing value for money.

If you use more filters, you can prolong that lifespan even more. Using 4 filters rather than just the two supplied gives up to 12,000 gallons of filtration use before a replacement is required.

The arsenic and fluoride reduction filter can also be used with a black filter. It is hard to remove arsenic and fluoride from tap water and this is why the filter is so impressive. It is rare to find this kind of functionality in a countertop unit.

When this filter is used the filtration process is slower and there is a shorter lifespan of just 1000 gallons. This type of filter uses activated alumina to target arsenic and fluoride in the water. Using adsorption, the potentially harmful particles are removed from the water.

Unlike other water filter systems, the filters are gravity-fed. This means that gravity forces the water through the filter from its top to its bottom with no artificial pressurization.

The long length filters and the water remain in contact for long periods to capture contaminants more effectively. Contact time is the key when using filtration methods such as absorption and adsorption.

What Sort of Water Can it Handle?

A Berkey water filter is ideal for use with all kinds of water. Whether you have a well or whether you have city water, you’ll find that these models produce excellent, contaminant-free, tasty water.

However, a Berkey filter is even more impressive than that since it can filter untreated water too. If you want to take it camping, for example, you can even filter lake water through it to produce safe drinking water. There is only one kind of water which cannot be filtered – salt water as it corrodes the elements of the filter.

What Kinds of Contaminants can it Remove?

Black Berkey filters remove or reduce pathogenic bacteria, cysts, parasites, viruses, trihalomethanes, pharmaceuticals, inorganic materials such as chlorine, VOCs (volatile organic compounds), heavy metals, sediment and rust. They also remove odors and unpleasant tastes.

The fluoride/arsenic filter is optional and can remove pre-oxidized arsenic III and arsenic V, fluoride, heavy metals and MTBE.

However, unlike many of its rivals, it will not remove any of the beneficial minerals found in water, so you can be confident that you’re choosing a filter system which will produce great tasting water too.

How About Maintenance?

These filter units are low maintenance with infrequent filter changes which can be accomplished quickly and easily.

The black filters last a very long time – often years – however over time they eventually clog up causing a reduced rate of water flow. The filters can be cleaned using a dish scrubber to scratch the outer layer away from the filter. Once this has been removed, the water will flow properly again.

Towards the end of the lifespan of the filter, you should test how effective it is. Since there is no warning light or other indicator to suggest when the filter has reached the end of its life, you will need to carry out some simple tests.

One way to test the effectiveness of the filter is to add some red food color to the water. This way, you can see easily if it can pass through the filter. If the red color goes through, it is time for a filter change since a fully functioning filter is capable of taking even coloring out of water. It’s recommended to try this test process once every couple of months to keep your system functioning at optimal levels.

What Steps Should I Take Before Buying a Water Filter?

Before you buy any water filtration system, there are a few things that you should bear in mind.

Firstly, you should always test your tap water. This is a key step when it comes to choosing the best water filter for you. If you’re using a Berkey filter as your primary filtration source, you’ll need to ensure you’re targeting the most appropriate contaminants. Fluoride filters will only be required if you use a city water supply since there is no fluoride added to well water.

There may be other pathogenic bacteria, contaminants and harmful chemicals in your water which affect its taste. These can be removed by most water filters, however many of their rivals also remove beneficial minerals which are actually good for your health. Therefore, a Berkey model is a good choice since it will leave the good minerals intact to help improve your well-being.

You should also estimate just how much drinking water your household is likely to require. All of the Berkey water filter models are pretty similar, however they are suitable for different sizes of household. The size of the model will also dictate the number of filters which you’ll require.

If you’re not sure which size to try, always go for a larger one than you expect. Remember that the average person will consume around 0.85 gallons of water per day. The Royal Berkey is the most popular choice, holding three gallons. Meanwhile, the Travel Berkey is the smallest, holding only 1.5 gallons.

When working out how much water you’ll need, it’s best to take half a gallon per day for each member of the household as your rule of thumb. This is only under normal circumstances, however. If you are very active or if the weather is extremely warm, you’ll need more than this amount.

If you’re also planning on using filtered water to cook with, that will also need to be borne in mind when figuring out how much water you use per day.

Not only that, but you’ll also need to think about preparing for any emergency situation such as a natural disaster. In an emergency, you’ll require at least two gallons of clean, safe drinking water every day for personal hygiene, cleaning and drinking.

There are six models in the filter range, each holding different capacities of filtered water. Each filters water at different rates too and this will vary depending on how many filters are being used.

Each model is supplied with two black Berkey filters but every model except the Travel Berkey allows you to add extra filters to speed up the flow rate of the water. If you’re keen to filter water as quickly as possible, you should choose a model with more filters.

The amount of time each model takes to filter one gallon of water relies on several factors including filter condition, the amount of filter elements in the system and how much water is in the chamber. You can keep the chamber filled with water to speed the filtration process since the amount of pressure is increased and this forces water through the filter more rapidly.

The third thing to bear in mind is the amount of space you have available in which to store your water filter system. How much countertop can you dedicate to water filtration? If you have a small kitchen, you’ll need to ensure you have adequate space for a larger model, or you’ll need to opt for a smaller version.

Also, remember that you will need to fill up the unit yourself with tap water. This means you should have sufficient countertop space close to the sink to make this as quick and convenient as possible.

If you’re in doubt about which system to buy, the Big Berkey may be the most sensible choice since it’s the middle-sized option. Suitable for most smaller families, it’s an ideal solution to getting rid of all the unwanted contaminants in your water.

Should I Buy a Berkey Water Filter?

With all of this in mind, you now have all the information you need to make an informed purchasing decision regarding the right water filter for you.

In conclude, if you’re looking for a powerful countertop water filter which requires no complex connections to your plumbing system, which is simple to use both in the home or while traveling, and yet which is capable of removing all of the harmful contaminants from the water effectively, one of the Berkey water filters that we’ve suggested here will be absolutely perfect to meet your individual needs.
