Whether you're looking for a water purifier for your home or a traveler's emergency kit, a Berkey water filter can help your need. Not only can it purify water from lakes and rivers, but it also can remove fluoride and nitrates. It's perfect for outdoor enthusiasts and families with small children.

The Berkey filter is a gravity filtration system that forces the source water through filters in the upper chamber. It's easy to set up and operate.

New Millennium Concepts, Ltd., in Texas, make Berkey water filters. They are made from stainless steel and use adsorption and microfiltration to filter water. Berkey filters have millions of microscopic pores that help to filter out a wide variety of contaminants.

Berkey filters are BPA-free, which is vital because some plastic water bottles are made with BPA, an unhealthy chemical for humans.

Berkey filtration systems are easy to set up and use. They are also easy to clean. Once the filters are in place, you should fill the system to the top to allow flow. The flow rate decreases as the water level in the top chamber goes down.

It's a good idea to place the Berkey water filter close to your sink or kitchen faucet so it's easy to access to fill the water.

Berkey filtration systems are designed to remove pathogenic bacteria and parasites from water. And Berkey reduces unhealthy minerals, cysts, and nitrites, which makes the Big Berkey system ideal for outdoor enthusiasts, families with small children, and people living in areas where water is not clean. They're also ideal for off-gridders and RVers.

The Berkey water filter is designed to fit into most homes and offices and can be installed under a cabinet.

You can install the Water View Spigot to allow a clear view of the water level in the lower chamber. This spigot has a tall glass, so you can see the water level without opening the filter.

Berkey filters are easy to use, clean, and a great way to help improve water quality. They're also a great way to reduce waste from plastic water bottles. They are a great gift idea, as well.

Don’t know how we lived without our Berkey! It tastes so clean and clear and my kids are drinking so much more water now that we are using the Berkey system.

Scott M. (Cincinnati, US)
Great gravity purifier

Son uses this at college and the Water quality and taste vastly improved versus what comes directly from the tap (municipal water source). Also, own a Royal Berkey for our home (family of 5). Coincidently, Entire household consuming more water than before Berkey ownership (including son at college using the big Berkey)

F carpenter (Murfreesboro, US)
We LOVE our Berkey!!

We got our Berkey about a month ago and we use it for everything! Drinking and cooking our food with it and we love the taste and purity of this water! It was easy to set up as well!!

Burton Stoesz (Belle Plaine, US)
Water tastes funny

I was so excited to get the Berkey system, and it was easy to assemble and is easy to use. The only problem is I hate the taste of the water! I have tried putting several batches through the filter to see if that makes a difference, but it still tastes bad to me. I used to have a Zero Water filter, and the water tasted so good, but this does not taste good to me. If you have suggestions for me, I'd love to try something to make it taste better.

Robin Fiegl (Hamburg, US)
Berkey Water

The water is crystal clear. You can actually taste the difference!

JM (Captain Cook, US)
Was Berkey around in 2003?

I moved to an area where county water isn't available and the only water was through a catchment system. I knew of UV disinfection systems and their faults when the recommended PPM requirements aren't met. I think it's called shadowing. When the water passing the UV light has particles that may cast a shadow on a bacteria causing the bacteria to pass into the water system. Something like that. I never got a UV filter. I put together a drinking water system that has an enclosed 2500 gallon tank and a dedicated pump and piping to the kitchen sink. This tank is filled with county water that is trucked in. Well fast forward to today, I have a cabin in a catchment area and this Berkey is perfect!

Margaret Ferguson (Tampa, US)
A Gift for my son's family

They love their Berkey! It is saving them a lot of money as they used only bottled water to drink. They have noticed a difference in the taste of their coffee too. All in all they are very pleased.

Lori Colbert (Junction, US)
Amazing water filtration

A friend recommended this water filtration system and after we were under a boil water order for a few days I decided to purchase one. I was not disappointed! The food dye test was a complete game changer for me!!! The water is so fresh and crisp and my entire family is drinking more water because it is so good and we know it is clean! I used it for a few weeks and gave it to my youngest daughter and bought a larger one for myself….and another for my other daughter!! I try to take my own water with me whenever I can! A great investment to know your family is drinking truly clean water! Highly recommend. Don’t forget to purchase the glass view water spigot. It is a must to see when the water level needs to be refilled. Trust me, you will drink more water than you ever did before and having the glass spigot allows you to see when you need to refill so you are never out if clean water.

Barbara (Southampton, US)
My Big Berkey!❤️

This is the BEST tasting water I have ever had! So refreshing, super clean, and totally hydrating!!! So easy to set up and maintain, haven’t cleaned the filters yet though, still new…this has to be one of the best purchases I have ever made! I LOVE my Big Berkey and would recommend it to anyone caring about the quality of their drinking water!!!
