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

It’s good but expensive and you need two lots a month in Bristol as the water is so hard which works out more expensive than having it connected straight to your water taps under the sink

Fitted the bill Perfectly
I purchased the 9.5 ltr water filter, I've been wanting one with mainly glass/metal construction. But also easy to clean and not difficult to put together, this fitted the bill perfectly.
Thank you for a very useful piece of kit

What made my experience great is that the ladies were so helpful and understanding. They evolved my problem and I returned my water jug back and got a refund straight away

I like these filters, ordering could be made simpler
I haven’t used the cartridges yet so can’t comment but they arrived in very good time as usual, and were well-packed. Generally I find the cartridges great and last a good few months for one person (all drinking and cooking water) in this area where the water isnt as polluted as the city where I used to live.
There’s been a change on the website, perhaps of product range, ¿company you buy from too? The images of the filters for my jug appeared different, without the plastic lids previously used and there was another unfamiliar filter displayed. So I was unsure whether I was ordering the correct filter. It would be a help to clarify this although it’s good not to use unnecessary plastic.

Best water filter ever
I was recommended zero water by a friend, being as though I live in a very hard water area and the amount of limescale deposited in my kettle was nasty! The water the filter produces tastes pure better than bottled water and its nice to know all the nasties are being withdrawn. More reductions on filters would be nice. Not sure how it would compare to a water distiller given the price of electric. Other than that no complaints excellent product.

A very good product
Speedy delivery of items. Very pleased with quality of water jug plus easy to fill and use. Filters do their job well. Like the meter, easy to see when it needs changing. I have always bought bottled water which is heavy now I don’t. I think this product is excellent and would highly recommend it.
