We strongly advise against freezing your elements as a general rule of caution. We also advise against storing the elements (even unused) in sub-freezing climates. The concern with freezing the elements is that any cold or freezing water will expand inside in the element, thereby increasing the pore size and ruining the element. Whether the […]
When testing a water sample, we recommend using this standard testing protocol
There are various plastic materials that can be leeched into water and the most common are BPA ( Bisphenol A) and 1,1-Dichloroethane (11-DCA). The Black Berkey elements have been tested to remove both of these plastic materials. Please refer to our lab testing results by clicking here
We determine the typical lifespan of the Black Berkey® Elements by their ability to reduce heavy metals. The breakthrough of heavy minerals can occur at about 3,000 gallons. Heavy metals can leach through beyond 3,000 gallons. However, the elements can be used beyond that point because other reductions continue well beyond 3,000 gallons.
Yes, our Black Berkey® Elements do remove Chloramine. Please click here to see the attached test results.
No, in order to reduce fluoride in your water, you will still need to use post filters that work in conjunction with the filters in your system. We have two types of post filters: the Berkey PF-2™ Elements which are used in conjunction with the Black Berkey® Elements, and the Berkey PF-4™ Elements that are […]
We recommend replacing Black Berkey® Elements every 3,000 gallons (6,000 per set of 2 elements). Elements may require replacement sooner based upon the quality of influent water.
If you just purchased your Berkey® system and the filters are hardly filtering water, the problem is typically due to high water tension. This high water tension prevents the air from being purged from the micro pores of the new filtration elements. Your Black Berkey™ elements need to be primed to purge this air out […]
With respect to the micron rating, NMCL does not use or publish a micron rating for the Black Berkey® Elements for the following reasons: There is much confusion with respect to nominal and absolute micron ratings. An absolute micron rating is one that states the maximum pore size expected within an element. The nominal micron […]
