What is worse, there are pages on the net that imply they are NSF Certified but in fact they are not.
Search for NSF Certification / Big Berkey Water Filters and you will find an example of what I am talking about! We're not afraid for you to look at Berkey's filter because when you read on below you'll understand why Multipure is a much better filter and any smart buyer will put his or her investment with Multipure.
Nowhere on the page does it actually say Berkey filters are NSF Certified but certainly the impression is given that they are. Personally I don't like a web site or company that tries to fool me.

Here is the proof that THE BERKEY WATER FILTER IS NOT NSF CERTIFIED:
Put " Berkey " in the "Brand Name" OR "Manufacturer" box that will come up on the followiing Official NSF Certification page, and nothing will come up!
Search for NSF Certified Drinking Water Treatment Units, Water Filters
Why does nothing come up when you type in "Berkey" on the Official NSF web page?
The reason Berkey Water Filter does not come up on the NSF site is that they are NOT NSF Certified even though some Berkey pages, without exactly saying so, lead you to believe they are.
If they SAID so they'd be sued so they carefully avoid saying it.
Now here's a page from a Berkey site that tells the truth -SORT OF:
On a certain Big Berkey water filter web site it says:
"NSF Certification is simply a list which they charge thousands of dollars to be on. It must also be updated constantly along with costs associated. Since we use their protocols and meet those standards as shown by our viewable testing results, we feel that to pay those high charges and then having to increase our prices is simply a waste of money. We want to keep our prices as low as we possibly can so that more people can afford the products."
So they admit it is not NSF Certified but claim "NSF Certification is simply a list which they charge thousands of dollars to be on. It must also be updated constantly along with costs associated."
Let's break down that statement:
Yes there are costs to have your filter analyzed by an independent world renowned non-profit lab and then have a data sheet issued showing exactly how much if any of each contaminant is reduced!
To say "NSF Certification is simply a list" is ridiculous! It is a true Certification by a truly independent world-renowned and trusted NON-PROFIT lab which certifies whether or not a filter reduces contaminants or not! Through scientific testing and analyzation, only then are they able to add it to the list of "NSF Certified water filters" - or NOT.
Not only are Multipure filters tested and analyzed for contaminants reduced, they are also tested and analyzed for Quality and Reliability of manufacturing and kept to a standard of truth in promotional materials; all of which is part of what the NSF is all about.
Also - and this may be why Berkey doesn't use the NSF labs? - the NSF REQUIRES that a company not use MISLEADING claims to make it sound better than it is or claim it reduces x or y contaminant when it does not!
So given the above info, do you TRUST them when they say their filters are lab tested to NSF Standards?
Please go to the above NSF web site link and type in " Multipure " under Manufacturer and you will find our listings that show over 80 contaminants that our filters reduce, including the latest NSF Standard 401 - Emerging Compounds/Incidental Contaminants - which is NSF Certified For:
Atenolol Reduction
Bisphenol A Reduction
Carbamazepine Reduction
DEET Reduction
Estrone Reduction
Ibuprofen Reduction
Linuron Reduction
Meprobamate Reduction
Metolachlor Reduction
Naproxen Reduction
Nonylphenol Reduction
Phenytoin Reduction
TCEP Reduction
TCPP Reduction
Trimethoprim Reduction
So when you buy a Multipure filter instead of a Berkey water filter you are buying a filter:
- guaranteed to reduce the contaminants it says it does,
- has a 90 day money back guarantee
- has a LIFETIME warranty on the housing so you only ever have to buy ONE...
