## Questions & Answers

**Q: I need to replace my berkeley water filter, do i have to buy the both black and white filter to replace them? or i can buy just the 2 white ones?**
A: The black ones are the filters for everything except chlorine and other water purification chemicals used by municipal water authorities. The white are for the latter ( chlorine etc). If you are filtering tap water you will need both, if you are filtering well water you only need black.

**Q: Are these authentic berkey filters? the berkley company (new millennium concepts, ltd.) have claimed there are a lot of fakes out there being sold.**
A: When ordered I got the genuine filter. Now I have no clue what they are shipping and that’s Berkey’s fault 100% They have way too many authorized distributors and don’t go after offenders / counterfeiters . They totally suck as a company from an operational point. For that reason, next time I need filters I’m going straight to propurusa and ordering their filters. They fit my Berkey and are a bit cheaper. Berkey has become cost prohibitive and is poorly run.

**Q: Which sellers are authorized berkey dealers and can be validated if i call new millennium concepts?**
A: Don’t know have a answer ... re read the amazon sites for that I have no issue with the items I have purchased at all all berkey products on the box when received

**Q: Purchased 4 bb9s and 4 pf2s in april 2016.  one bb9 nut striped out after a year. now a second nut has striped out.  can you help me?**
A: Are you talking about the white ? Screw down bolts that hold the filters on ? Are you hand tightening or using a wrench ?
