Water Filter vs Water Purifier - What's the difference?

The term water filter is commonly used to describe many water filtration products, including the Berkey Water Filter systems. While the term can be an accurate description, the meaning when talking about water treatment standards is different.

Let's take a look at the two standards when classifying water treatment devices...

Water Filter Requirement

CONTAMINANT

SPECIES

REMOVAL STANDARD

Pathogenic Bacteria Klebsiella terrigena

greater than

99.99% reduction

Known as (Log 4)

Water Purifier Requirements

CONTAMINANT

SPECIES

REMOVAL STANDARD

Pathogenic Bacteria Klebsiella terrigena

greater than

99.9999% reduction

Known as (Log 6)

Virus Polio and Rota

greater than

99.99% reduction

known as (Log 4)

All Berkey systems contain the Black Berkey Filters and meet the Water purifier standard. In fact, Berkey Purifiers far surpass this standard and actually remove 99.9999999% known as a log 9 reduction, when dealing with pathogenic bacteria. This distinction is what makes Berkey the only certifiable gravity flow water purification system.
