Coldstream Ceramic Water Filter FTO Plus – Suitable for Stainless Steel Gravity Systems – Fits all Berkeys and ProOne Water Filter sizes

This filter is for use in with all sizes of Berkey housings, as well as the British Berkefeld, ProOne and Walter Filter systems.  Install FTO Plus filters in your Gravity system to ensure safer, healthy drinking water with a great taste. Ideal for use in your home, cottage, cabin, office, camping, cafes, off-grid homes, and in the field by international relief organizations.  Made in the UK.  NSF Certified.

NOTE:  Using this filter replaces both the Black Berkey Element and the Berkey PF-2 Fluoride Element as it also removes fluoride. 

It does not require priming or the red dye test, and filters faster. So life is easier!

Use minimum 2 filters in your upper chamber.

For faster filtration speed and longer filter lifespan, use 4 filters in your Big or Royal Berkey, 6 in your Imperial and 8 in your Crown Berkey.

Rated capacity is 1500 liters using 2 filters which is 6 months if filtering approximately 8 liters per day.  We recommend having a backup pair on hand.  When you install them, mark in your calendar 6 months ahead to replace them.
