Water Filter vs. Water Purifier

Water Purifier

In order to be in this classification the following standard must be met:

Contaminant	Species	Removal Standard	Berkey Removal %
Pathogenic Bacteria	Klebsiella Terrigena	>99.9999% (Log 6)	99.9999999% (Log 9)
Virus	Polio and Rota	>99.99% (Log 4)	99.99% (Log 4)

 

All Berkey systems contain the Black Berkey Filters and meet the Water purifier standard. In fact, Berkey water purifiers far surpass this standard and actually remove 99.9999999% known as a log 9 reduction, when dealing with pathogenic bacteria.

Berkey purifiers also reduce viruses by 99.99% (log 4 reduction). This distinction is what makes Berkey the only certifiable gravity flow water purification system on the market.

Water Filter

This classification must meet the following standard:

Contaminant	Species	Removal Standard
Pathogenic Bacteria	Klebsiella Terrigena	>99% (Log 4)

 

To see how Berkey stacks up against other brands, head over to Berkey vs. The Competition. Take note that some use harsh chemicals, like iodine or chlorinating tablets, in order to reach the level of purification. We do not have to use chemicals in our unique ionic adsorption process mated with simple microfiltration. In short, these two methods create a pore structure so minute that contaminants are removed from the water because they simply cannot pass through the charged filtering media.
