So why do YOU call it a softener (even in quotes)? It's not: it's a scale
inhibitor plus sediment filter.

Since it seems to contain some sort of ion exchange resin to "inhibit"
the scale, I presumed it did so by the process of softening.

I am wondering, having read the other replies, whether this is half a
softener, in as much as it seems to contain a cartridge of resin but
lacks the recharge mechanism?

Does anyone know exactly what this is and how it works?

I did note that screwfix did not go as far as calling it a softener
and that's why I used the quotes to signify that I was not sure. That
it appeared on the same page as some other magical scale inhibitors
made me ask whether this too was just another of the same.
