I finally got my Berkey!

I have wanted a Berkey for over 20 years and for whatever reason, just never did it. I'm an environmental engineer that deals with contaminated groundwater and putting treatment systems on contaminated wells, so I have always known the importance of filtering out contaminants from drinking water. I've been filling up gallon jugs of water from the local UV water kiosk for years and hauling gallons and gallons. I've done my research and always knew that Berkey was the only way I wanted to go. It took me getting a small bonus at work to finally treat myself and come to to my senses and think - what I am I doing? - just buy the Berkey! So, I finally did it and couldn't be happier. No more hauling water - I have the greatest filtered water any time I want. The Big Berkey is so sleek and nice looking and provides quite enough water for me to use in cooking, making tea and for drinking (me and the dogs). The assembly was fairly easy and was happy that the spout did not leak! The only one thing that I wish was easier for the installation is the priming of the filters. Using the little rubber gasket to hold between the faucet and the filter is a little less than perfect - water goes spurting all over if you don't line it up just right and get a really good seal. But this is definitely not a reason not to get a Berkey and follow all installation directions. So happy with my purchase and looking forward to many, many years of clean drinking water.


My husband and I are loving our Berkey. Easy to set up, use, and our water has never smelled or tasted fresher. Thank you.

great water

This one was for my son's family. I've had one for a few years. I love mine. My son's trying to find a spot for it.....

I love it.

Makes my life a dream.

Blemished Berkey???

If my Berkey filter was a blemished model I have been unable to find a blemish. It arrived in perfect condition, was easy to assemble, and I have the satisfaction that I am drinking pure, noncontaminated water. I am so happy with this purchase.
