Berkey Gravity Replacement Filters from ProOne

Berkey Gravity Replacement Filters from ProOne

Can I use this filter for a gravity system from a different brand?

Most likely!  You may be able to upgrade your system by using ProOne® filters without needing to purchase a completely new system. 

For example, the ProOne® 9" G2.0 filter is designed to work with:
  • Travel Berkey - 1.5 Gal
  • Big Berkey - 2.25 Gal
  • Royal Berkey - 3.25 Gal
  • Imperial Berkey - 4.5 Gal
  • Crown Berkey - 6 Gal
  • Berkey Light - 2.75 Gal
  • Most other gravity system brands that use a standard 2" by 9" water filter element

Why is Propur® ProOne® G2.0 filter superior to other brands?
  • Easy to install, use and clean - no priming required and no additional add-on filters necessary to remove fluoride
  • Infused with silver to prevent bacterial growth
  • It is ideal for most water sources including lakes, rivers, streams, ponds, rain and tap water.
  • Helps reduce or remove heavy metals, fluoride, pesticides, herbicides, chloramines, bacteria, pharmaceutical drugs, VOC’s, viruses, Giardia and more without any add-on filters (click here to view published lab results)
  • It has been tested to meet NSF/ANSI 42 and 53 standards, and the only “ALL-IN-ONE” CONTAMINANTS & FLUORIDE GRAVITY WATER FILTER that qualifies as a microbiological water purifier by NSF/ANSI protocol P231.
