“…The quantitation limit of an individual analytical procedure is the lowest amount of analyte in a sample which can be quantitatively determined with suitable precision and accuracy. The quantitation limit is a parameter of quantitative assays for low levels of compounds in sample matrices, and is used particularly for the determination of impurities and/or degradation products…” REFERENCE: […]
NSF certifications are not required but rather optional. In our opinion, NSF certifications are limited in their application with respect to our gravity fed purification elements. NSF Standard 42 (aesthetic effects) and Standard 53 (health effects) would specifically apply to our purification elements. NSF Standard 42 covers systems “designed to reduce specific aesthetic or non-health-related contaminants […]

Do your Black Berkey® purification elements filter out all the drugs/pharmaceuticals that are in our city-water?
We have no way of knowing exactly what potential contaminants may be in each person’s water supply. What we do know is that our Black Berkey® purification elements filter out numerous pharmaceutical drugs and endocrine-disruptors (EDCs); such as BPA, Naproxin, Octylphenol, Progesterone, THM’s and many more.
