On the whole I do think the new Culligan water filter is an improvement on the older Zero version. The TDS meter is easier to read, the jug doesn't spill like the older version and it is easier to cl... See more

A pleasure to deal with
A pleasure to deal with. Super quick delivery, good communication and great offers. Oh, and of course, the best water filters in the UK bar none. Not the cheapest out there but definitely worth it.

Easy to order Culligan 1.7 ltr jug
Easy to order Culligan 1.7 ltr jug, arrived on time with clear instructions. Bought as my older ZeroWater jug spilt badly when filled to near the top. New lid design seems good but did seem to leak a bit when the jug full. Too early to judge, but slimmer shape is good.

Received promptly and we'll packaged
Received promptly and we'll packaged.
I find the jug with filter in very heavy and I only bought the couple's size not the larger size. I struggle to lift and pour as an older person.
I'm not sure about the taste of the water, something to get used to.
I hope the benefits outweigh the deficits.

Water is so clear and chemical free is amazing to drink.
Shocking how much crap is in our tap water.
Was reading 326 before filtering to 0!
