We are excited to announce the release of our Berkey Water Filter Calculator Phone/Tablet app for both Apple and Android devices. This calculator provides a quick calculation based upon your daily usage and how many filters you have installed. It answers the age old Berkey question "When should I replace my berkey filters?" and will let you know whether your filters need replacing or tell you approximately how many months you have left.

This Berkey Filter Calculator app covers the popular black berkey and PF-2 fluoride filters, in addition to the older generation 7" and 9" white ceramic filters. Also, don't forget you can also always verify black berkey filter performance by performing a red food coloring test on them. Below are some screenshots of the app.
