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 go 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.

Rebecca Thornton (Arvada, US)
Excellent water filter!

My husband and I are so pleased with this water filter. The water always comes out crystal clear and tastes so clean. No mineral or chlorine taste whatsoever! We are very happy with this purchase.

Emaline Spangler (Wichita Falls, US)
Big Berkey review

We have used the Big Berkey for a month and have been happy with our purchase. The size works well for two people. It does have a slight rubber taste from the two plugs but it is less noticeable after 30 days. Our city’s water supply comes from a lake and it has a fishy taste and smell but the Berkey removes it perfectly.

Linda Fink (Schenectady, US)

Great tasting water. Hydration is no longer a hassle. Added benefit no more 2.5 gallon plastic jugs! At 68 years old this product is a life saver.

Terri DiLello (Wallingford, US)

I purchased the Berkey as part of my emergency prepping “kit” which I hope I never have to use in that capacity. However, we did assemble it and tried it with our extremely hard well water and it was clean and refreshing. I dried the inside and allowed the filters to dry as much as possible and then put it away. Hopefully it’s not contaminated but if it filters swamp water, I don’t see what I did being a problem. If an emergency, I will gladly take my chances drinking “contaminated” water than not having any water.

Jessica Smith (Roseville, US)
So far so good

Ordered the Berkey and we have been happy with it so far. It removes food coloring, that yucky fridge water taste, and is easy for the kids to use. My only sadness is that the fluoride filters were out of stock and I’m still looking forward to ordering those.

JOHN FRIES (Sioux Falls, US)
Received but not set up yet :)

Thank you.

nanci perruna (Stony Point, US)

love the test of the water

Laura Pratt (Kalispell, US)
water filter

We haven't tried it yet, as we will be storing it for future use and didn't want to risk any contamination. It looks vey well-made and has good instructions. We bought it for emergency use.

David Wilson (Holland, US)

Glad to have it with the unknown elements in the water these days. Water supply in the KC area is the river and or runoff from fertilized fields. The Berky gives me a sense of security when I drink water. Thanks

Douglas McVey (Arlington, US)
Great tasting!

Extremely happy with our new Berkley filter system....the water tastes great and easy to use. Bought one for our daughter as a house warming gift...Don't tell anyone.
