The lager size 4.2 litre jug is excellent. I like the taste of London water but this cleans and sweetens slightly so fine for me. Maybe won't go into a fridge but I want the water at room temperature anyway. Also not so good for people who may have a problem lifting the weight of this size jug when full. Go for the lighter 2 litre jug. Very simple cartridge set up and does the job. Very pleased. !
