You may have heard of the Berkey Water Filters for quite some time now or even maybe tasted a Berkey Filtered water from a friend or family's house. Now, I know you are wondering how Berkey Water Filters work and you may have a lot of questions. This is why we've created a complete guide to help you out from deciding what size works best for you and your household to proper care and maintenance or your Berkey.
Let's get started!
You will be in-control of what you drink which in turn gives you confidence. Knowing that your everyday drinking water runs through elements specially formulated to address 200+ typical contaminants found in tap water, you will certainly have peace of mind.
A healthier body. When you have a great-tasting water, you will be inclined to drink more of it. Enjoying a sip of your refreshing Berkey water quite often will also equate to a healthier and more nourished body.
Better-tasting water, always within reach. Because a Berkey sits right on your counter and holds gallons at a time, refreshing filtered water is always at arm's reach—for drinking, cooking, coffee, tea, and even your pets' bowls.
No installation required. A Berkey needs no plumbing, no electricity, and no special tools. Simply set it on the kitchen counter, fill the top chamber with your tap water, and let gravity do the rest—an easy upgrade for any household, and just as easy to move if you rearrange or relocate.
There are quite a lot of gravity-fed filters on the market, and all of them claim to have superior abilities in filtering your water. So why choose Berkey? It is simple. Berkey has earned its reputation as the gold standard in gravity-fed water filtration. Berkey® systems are powerful, freestanding water filter systems that sit on a counter top or stand. Simply pour treated municipal tap water into the top chamber of the system, and dispense freshly filtered water easily from the lower chamber through a handy spigot. The systems are easy to use—no electricity, tools or plumbing needed. Enjoy clean, delicious filtered water that retains the healthy minerals your body needs for less than 2 cents per gallon.
Black Berkey® Elements are the heart of every Berkey system. They are specially formulated to address 200+ typical contaminants found in tap water, thanks to a proprietary blend of filtration media compressed into a compact matrix containing millions of microscopic pores.
Many water filters on the market rely on simple activated carbon alone. The Black Berkey® Elements instead combine several media types that work together to reduce a much broader range of common tap water contaminants—including chlorine, heavy metals such as lead and mercury, trihalomethanes, volatile organic compounds, pharmaceuticals, pesticides and herbicides, petroleum products, and PFAS. Performance for these contaminant categories has been verified by independent third-party laboratories, and you can review the official Black Berkey® Elements test results for the full details.

This is the first thing that most people consider when purchasing a Berkey. To help you choose the best size for your household, you must first consider the number of people in your family and their water consumption. On an average, one person consumes half a gallon of water every day. If you have 2-3 people in your home, a Big Berkey may be ample enough to supply you daily plus enough water for your cooking.
Here are the various sizes of the Berkey Water Systems:

All Berkey System comes with 2 black Berkey elements. Having more than 2 Berkey elements will not improve the filtration quality but by adding another 2 filters in your system there would be an increase of flow rate and it will extend the lifespan of your filters. For example,
If you purchase 2 elements, it would take an hour for your water to be ready to drink.
While if you have four filters, it will cut the waiting time down to half and your filter would be able to finish filtering your water in half an hour.
In addition, two filters will filter 6000 gallons of water, four filters will filter 12,000 gallons of water.
If you consume 4 gallons a day, the 2 black filters will last you a little over 4-5 years and 4 filters will last you for at least 8 years.
For the first one, it may take a little bit of a calculation. If you have a two filter Big Berkey and your used 4 gallons of water per day. You would multiply 2 (#of filters) by 3000 = 6000 (Total Life), then divide 6000 by 4 (total use) = 1500 days the filters will last, That's a little over four years!
For the second method, all you have to do is observe. The Black Berkey filters in your unit will never stop working. The rate that the filters produce water will slow down. This is an indication that the filter needs to be cleaned. This brings us to the second method. If after cleaning your elements they do not filter any faster; it is time to replace them.
