Prefect addition to my countertop!

Absolutely loving my new water filter system. I noticed a difference in water quality straight away and won’t look back. The hot water feature makes my morning brew a doddle too. The fact the filters last a year is brilliant. An investment but worth the money.

Prefer the k19

After buying the k19 and being so happy with it I brought this for my caravan that I spend quite alot of time in. It's abit smaller so seemed a perfect solution.
It's glitches alot after refilling, I have to unplug to reset alot.
I'm going to ring for some advice about this
