Review summary

Created with AI, based on recent reviews

Evaluating 389 reviews, reviewers had a great experience with this company. Customers frequently praise the fast delivery service, noting that orders arrive promptly and well-packaged to their homes. People are also deeply impressed by the exceptional quality of the water filtration systems, which effectively remove impurities and make tap water taste clean and refreshing. However, some people mentioned that the replacement filters had a surprisingly short lifespan and sometimes developed an unpleasant smell after just a couple of weeks of daily use. Consumers also noted that securing future replacement parts became rather complicated since the business decided to close its direct distribution operations in the region.

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

I have used the zero filter system for…

I have used the zero filter system for more than a year now and I have absolutely loved the great tasting water, I have been using pink Himalayan salt to put some of the minerals back in but overall I would highly recommend it. The reason I have given it 2 Star’s is because within two weeks the water starts smelling fishy, and it’s not a smell that you can get over it is stomach churning. I bought a Brita jug and have been filtering the water from there before putting it in the Zero to hopefully make the filters in the zero last longer, but it’s a lot of work and incredibly expensive buying both sets of filters. I feel the price of the zero is absolutely ridiculous, especially in areas like mine where there is obviously a high concentration of Rubbish. I have now bought a water 2 system with the fluoride filter add on, it is not going to get rid of all of the rubbish that the zero does but it is a fraction of the price, and it gives me peace of mind.. so buy the zero if you are Rich!!! but avoid at all costs if you are a normal hard-working person with bills to pay

Disappointed …

Extremely tight fitting lid and water chamber when fitting the filter.
The TDS meter is placed under the handle, making it very awkward to insert, read and remove. Shame the jug design has changed, but it pours well. Not user friendly.

Fishy smell after 3 weeks

After 3 week, the filer started to smell fishy. Apparently this happens when the filter stops working g and as I live in a hard water area, the filter only lasts for 3 week!! Too expensive to change so frequently. What a shame as the water quality was exceptional, before the decline.

Tap has been leaking for so long

Tap has been leaking for so long, I've emailed a whole week ago and no reply, so disappointed especially having brought the glass expensive filter, very annoyed with the customer service!!

No more bottled water for us! 7.5 litre dispenser

I had an issue with the TDS meter but customer service (help) were very good and even though the company are now not fully functioning, replaced the meter very quickly and efficiently. I am very pleased with the Zero Water device and the quality of the water. No more bottled water for us!

Usually good but this experience was poor.

I've been using these products for a while and have never had any issue with service/quality of product. I bought a new jug at the beginning of the year and shortly after there was an issue with the TDM meter. Contacted customer service and they needed a picture which I provided and said it would be rectified. I think the company then shut down their own website (not sure what exactly happened) but I was then told I couldn't be helped and they couldn't send a replacement TDS and directed to Lakeland where I had to buy a new jug even though I didn't need one - just for the TDS meter. Not a great experience.

Great gift

I bought this to gift a family member. They are impressed with how much better the water tastes and feels. Well worth the purchase.

Excellent product

Excellent product, very efficient.
However, with Culligan announcing the end of the online store, it is unclear about the ongoing reliability of supplies
