Water Filter System Giude

Average Reviews:

(More customer reviews)The standard berkey filter removes only larger particulates and the black berkey elements are made of activated charcoal.

Berkey has published no evidence tthat their filter can remove viruses which are usually several orders of magnitude smaller than bacteria and parasites/cysts.

Berkey also has not published comprehensive test results such as are commonly provided for RO filters. I would guess the reason they have not published such information is that their filter, unlike RO units, is ineffective against most dissolved contaminants or even very small particulates such as viruses. The lack of any such published data of their filter's efficacy is why they cannot be sold in California.

Berkey is essentially selling a filter that they do not provide comprehensive specs for and claim that a TDS meter will not quantify its efficacy. So, that leaves a typical user with no way to test the effectiveness of the Berkey filter. I certainly would not trust Berkey any more than I would a municipal water company, and probably much less since at least the water company publishes their test data.

Berkey's advertising material claims their filter is effective on a variety of contaminants, but they do not specify the test conditions (concentration of contaminants in the feed water among other things).The test data they released from reputable labs only address a handful of contaminants (the substances that are the easiest to remove such as E. coli and chlorine--using the activated charcoal/black berkey elements)

Also, how does the Berkey filter distinguish between "healthful" and "unhealthful" minerals/metals/substances? What it comes down to is the Berkey filter will remove a portion of the substances that are attracted to activated charcoal if the black berkey option is used, and a portion of the substances attracted to alumina if the fluoride/arsenic option is used. If neither option is used, all it does is remove the larger particulates. (It's funny that a "minute" unquantified amount of aluminum compound (presumably mostly aluminum oxide otherwise known as alumina) introduced by their fluoride filter is harmless, but a minute amount of fluoride and other substances is a serious health hazard.)

There is no evidence the Berkey filter with or without the optional elements is superior to any RO system. Since Berkey does not provide comparable test data, we have no way of knowing with any certainty though basic chemistry and the data from a simple TDS meter strongly suggests the Berkey filter is not effective against dissolved contaminants.

(More customer reviews)We needed a second filter for our cottage where we spend 8 weeks a year. Our other is a Berkey Light. The water tastes equally good (excellent) and the prep of the filter elements was easier. The only con was that the plugs for the holes for extra elements were incredibly difficult to insert, but I feel certain that they won't leak! I recommend.

(More customer reviews)I L O V E T H I S W A T E R F I L T E R . . . ! Gravity makes it work (no electrical cost and works during power outages), two black Berkey filters lasts a year if you purify 3 gallons a day. CHEAP!I have two PF-2 filters added to mine to filter out the fluoride added to our city tap water (and any arsenic).

I have a sense of peace and satisfaction I have never gotten from another product other than maybe my first car. (I have mostly retired my car do the cost.)

Buy one of these babies SOON because there is and is no doubt going to be a run on good water filters. You'll be glad you did. (And NO I don't sell them nor do I know anyone who does -- though I sure would like to sell them).
