Bi-Flux splits the flow into two paths through the cartridge, which speeds up a pour that is otherwise the most irritating thing about a gravity jug. The range includes a bacteriostatic silver variant and a magnesium-active version, and the naming across them is confusing enough that ordering by product code rather than description is worth the effort.

What it removes — and what it does not

Listed because it is the more useful half. Every cartridge on the market reduces chlorine taste; what separates them is what they leave behind.
The manufacturer states the reduction. No independent verification is offered. Common on European jugs, which are generally not NSF-certified at all because NSF is a North American scheme.
