Berkey vs Propur infographic

Berkey or ProOne? ProOne or Berkey?

If you're thinking about buying a gravity water filter, there's a good chance you've narrowed your choices down to these two brands. They look similar and they cost about the same, but there are some differences that you'll want to know about. 


This infographic sheds a little light on some of the ways they differ. It compares the Big Berkey and the ProOne Big+ (formerly called Propur Big) since they're the most popular models and are almost the same size.

Berkey vs Propur infographic

Both of them eliminate a whole host of contaminants from drinking water. There are way too many to list in a chart like this, so I've included just a sampling for the sake of comparison.

I hope you found this infographic helpful in making your decision.

I own a Berkey myself, but ProOne wasn't around when I bought it. I wouldn't hesitate to recommend either of them. They're both good quality filters that will give you clean, safe, and great tasting water.

  1. Thanks for the comparison! I’m surprised to see the significant difference in terms of lead and aluminum. Based on the infographic, ProPur seems to completely blow Berkey out of the water for reducing those contaminants, and those are among the most important ones to remove. This alone could be the deal-breaker that would guide me towards ProPur!

  2. I recently but a Berkey and I am extremely disappointed so far. I have the travel Berkey. I had no problem priming it and it is filtering the water except that after 5 full chambers of filtered water The Taste is absolutely terrible way worse than the tap water that is going in. Not sure what to do at this point since like I said I have run at least five full of chambers of water through the filters. The water tastes like chemicals. The water coming directly out of the tap taste much better. Can anyone provide some help.

    1. Hi, Randy! There’s obviously something wrong with it. I’m assuming you double checked to make sure that it’s put together properly and nothing is leaking through. Also the red dye test is a good idea. If you just got it, it should be under warranty. I suggest contacting the manufacturer or whoever you bought it from and asking them to replace it. I trust you bought it from someone reputable.

  3. I currently have a Berkey water system but want to switch to ProPur filters. Will ProPur filters fit in my Berkey system? Have you tried ProPur filters in your Berkey system or just bought a whole new one?
