How Crown Berkey Works

The Crown Berkey filter system is a gravity fed water system that works for indoor use, outdoor use and emergency situations. In fact, this system was created to handle large groups of people in natural disasters and other emergency situations and can be used by more than six people to provide clean water. Composed of granular activated carbon, the Black Berkey Filter removes over 200 contaminants including heavy metals, chloride, glyphosate and other materials. It prevents bacteria growth and keeps the good minerals in the water, plus exceeds NSF/ANSI 53 standards when tested by state and EPA accredited laboratories. The Crown Berkey is made of high quality stainless steel and takes a little less than one hour to filter one gallon of water, and holds six gallons. Each system purchased from Berkey Filters comes with the Berkey Care lifetime warranty.

How Zen Rejuvenate Water Filter Works

Cost

The Crown Berkey seems expensive with the initial cost at $360, but the $114.95 price tag on the Rejuvenate can be deceiving. Part of what makes the Crown Berkey stand out are the Black Berkey filters, which last up to 6,000 gallons and are easy to clean and maintain. If you were to use three gallons a day, the initial filters could last five or six years.

Let’s look at the math. The Crown Berkey price per gallon for 2,400 gallons is 15 cents per gallon when you divide the starting price ($360) by 2,400 gallons. For the Rejuvenate, you’d have to change out multiple filters multiple times to hit 2,400 gallons. The Micro Ceramic Filter has to be replaced every year (or 1,000 gallons) and the 5-Stage Mineral Filter Cartridge has to be replaced every six months (or 500 gallons.) If you want it to be affordable, you’d want to get three, annual maintenance kits so that it lasts at least 2,400 gallons. Those are $67.95 per kit, plus you’d want to get the 5-stage filter at $18.95 since it only lasts six months. To get 2,400 gallons out of the Rejuvenate, it would be $269.80 or 11 cents a gallon. Yes, this is still cheaper, but what if you wanted it to last the same lifespan as the Black Berkey filters? You’d want to get five annual maintenance kits to make it last that long. For those, plus the system, it’s $454.70 or 8 cents per gallon. In the end, it costs nearly $100 more than the Crown Berkey.

Performance

Zen Water Systems offers little information on how well any of its systems perform, including the Rejuvenate. Unlike Berkey Filters, which shares lab test results and percentages of what is filtered out of the water system, there is little to no information provided by Zen Water Systems on what is filtered. Zen notes that over 99% of chlorine, bacteria, pesticides, herbicides and hundreds of other chemicals are removed, but fluoride isn’t. Berkey removes lead, chloride, chromium, copper, chloroform, bacteria, pesticides, viruses and more. And with the Berkey Fluoride Filters used in combination with the Black Berkey filters, you can remove over 97% of Fluoride as well.

The majority of Berkey water filters, including the Crown Berkey, have an advantage with their high quality stainless steel finishes, which look more appealing and are less likely to mildew like the Rejuvenate’s plastic finish. And with the Crown Berkey, it’s easy to maintain with washable Black Berkey filters that can filter up to 6,000 gallons while the Zen Rejuvenate has multiple filters that need to be changed at different times.
