Lab Test Reports for Berkey Filters

The Black Berkey Elements far surpass other water filters in filtration capability, as evident by their extensive filtration specifications. These elements have a specialized process that is due to their unique structure. The element's filtration media is a combination of micro-pores, which trap harmful contaminants, and revolutionary material with adsorption and ion exchange properties that essentially attract molecules to the media, preventing them from passing into your drinking water. A pair of Black Berkey Elements comes standard with every Berkey Water Filter System purchase.

How to test your filters at home:

We recommend doing the Red Dye Test as soon as you get new filters and every 3-6 months. It's very rare, but possible that your filter could have been damaged during transport. Doing the Red Dye Test is a DIY way to check your Berkey filters are working properly. 

We do NOT recommend using a TDS meter for Berkey water. It does not show the filtering effectiveness because of the mineral composition in Berkey water.
