California, Iowa and Wisconsin regulations prohibit the making of any health claims, such as the removal of pathogenic bacteria, on residential filtration systems using post carbon filters.

Fairey Industrial Ceramics Limited (trading as Berkefeld Water Filters) is registered with the EPA under Establishment Number 69096-GBR-1.

Even though Berkefeld products are registered with the EPA and NCF certified, these 3 states prohibit the making of any health claims, such as the removal of pathogenic bacteria, on residential filtration systems using post carbon filters. Sorry, we have to follow government rules.
