Description
Biofilm drops with silver and copper ions are a simple solution to a common problem with gravity water filters: algae growth in the lower collection chamber. Because Black Berkey filters deliberately add no chlorine, a biofilm can form over time in stored, filtered water. These drops prevent that.
How it works
Silver and copper ions have been known for centuries as oligodynamic elements that inhibit the growth of bacteria, algae and fungi. By adding a few drops to your lower filter chamber, the water stays clear and free of biofilm. The added concentration is too low to give any taste or health difference in normal use.
Dosage
A few drops per litre of water (see the packaging for the exact dosage). One 60 ml bottle lasts many months to more than a year in normal use.
Compatibility
Suitable for all Berkey water filters (Go Kit, Travel, Light, Big, Royal, Imperial, Crown) and comparable gravity collection systems.
Features
60 ml biofilm drops, silver and copper ions, prevents algae growth in the lower chamber, suitable for all Berkey models, indispensable for long storage or high temperatures, odourless and tasteless at normal dosage.
