Culligan ZeroWater 5.2 L Ready-Read 5-Stage Water Filter Dispenser, IAPMO Certified to Reduce Lead and PFOA/PFOS, Instant TDS Read Out

It’s not perfect but it does what it promises: total dissolved solids go from ~350 to less than 10- even zero. Minor gripes: 1: reservoir could be bigger as have to reload 3 times to fill the jug. 2: when the filter goes off it goes off quick and smells like ditchwater. Possibly would be less of a problem if fitted in fridge. 3: the new filters don’t fit. I bought the jug in May 2025, in July it’s already obsolete. I am reviewing this item not the appalling behaviour of the company. But if you want an alternative to reverse osmosis or distilled water and don’t have high volume demands this was a perfect solution.

Absolutely brilliant! We are based in West wales and myself and my family have been living of bottled water for 5 years because the water smells strongly of chlorine or ammonia. So as instructed in this amazing devices manual, I tested the tap water and had a reading of 85. After running the tao water through the filter. It reads zero every time! But them we decided to test the bottled water, we had 2 types at the time. Each reading over 300!!!!! Which is way worse then the tap water!!!! I was concerned that maybe if the filters were taking all the bad stuff out, is it taking the good stuff out too... and if so then what can I do to add some good stuff back in. Well I don't think you need to as the water seems perfect but I did a little experiment after researching water. This will blow you away haha. My daughter made up some ice cubes in the freezer using an ice cube tray. She couldn't understand why the ice cubes were so cloudy as she was trying to get clear ice cubes. So after filtering the water I then 'spoke' to the water thanking it and giving my gratitude.... we put the tray in the freezer. The results were incredible!! Clear ice cubes with tiny bursts of what I can only describe as 'light' and beautiful ripple patterns. Please try this experiment yourselves! We made an ice tray and said nothing to the water and a tray of ice cubes expressing gratitude to the water several times. I'm telling you this because with our words we managed to restructure the water. Has water got an awareness? Is it conscious? So do we need to add anything to the water? Absolutely not. Just words of gratitude tht restructured the water! Fun to experiment and definitely a learning experience!!! Great fun to do with the kids! A great water filter!!!!!!

This is the first time I have left a bad review for a product in Amazon. This one is well deserved!! Sad to say that this product is woefully bad. Not bad in the build quality sense, but bad in the sense that it is a HUGE FINANCIAL CON. For a family of 4 this product is going to cost you no less than £750 a year, EVERY YEAR, in replacement filters. They don’t mention this anywhere. It is vital that people understand this BEFORE making the purchase. When the filters expire, usually within 2 weeks, they make the water smell and taste like rotted fish and the ppm reading is double what you would get out of the tap. I am sending mine back for a refund as this is a disgraceful misrepresentation and is NOT FIT FOR PURPOSE. Separately, the customer service from ZeroWater is disgraceful, disingenuous and lays all the blame on the customer. Perhaps if they advertised their products saying “for a family of 4 this product will cost you £750 every single year in replacement filters” they would have NO CUSTOMERS. If I described one of my products to my customer like this I’d be done by Trading Standards for false advertising.

Great dispenser. Easy to set up. Works brilliantly. Only just realised the handle/pour feature instead of tap. Quite compact, and sturdy. Cartridges a bit pricey, but last ages. Very happy with it!

The filter is convenient to use. Unfortunately, the filter cartridge is defective. I have been using these filters for over 2 years and it has never happened that the filter cartridge stopped presuming water after such a short time.

This model of water jug is so handy and convenient. I have to keep topping up with water as the container doesn't hold much, exactly 1l. The water is really clear and the taste is very much or even more than mineral water, but the filter didn't lasted more than 2 weeks. The tap water in our area is 305, really bad and the filter must be changed more frequently than I hoped for. Therefore we stopped using this jug as it is cheaper to buy mineral water than using these filters. There wasn't even any discount on them on Black Friday!

I was worried about buying this as there were a lot of people saying that it leaked and that the filters only last a couple of weeks and at around £20 per filter, I didn't think I'd be able to "run" it. BUT, I have had zero (parden the pun) leaks and I started using it on the 16th April and it is the 8th May today, so around 3 weeks of use and it's STILL showing 0.000 on all 3 of my TDS meters. I wonder if the people who had leak issues were not placing the tap in tightly enough ??? I thought I was going to break it where it had to be almost forced in, but touch wood, it's worked, no leaks. It fits nicely in my fridge and the water itself tastes so good..... I don't know why I would need to, but I would definitely buy again if needed.

It works just as advertised, but in hindsight I regret the purchase as it take out all the beneficial minerals like calcium, magnesium etc.

They aren’t lying with their advertising an the water tastes great.

Sehr gut

The only company to give a TDS tester along with product. Says everything about the quality they bring. Needs to run 1-2 full loads for brand new filter cartridge before drinking for me. Needs regular topping up. Needs constant checks because at 006 you’ll need to change cartridge. Water tastes sweet when filter runs out. Change immediately to avoid weird sweet taste and feeling. I’d still give 5 stars because it’s a top tier simple design affordable water filter. Does what it says. 👍🏻👍🏻 ⭐️⭐️⭐️⭐️⭐️

I’ve been using this ZeroWater dispenser for just over a month, and honestly? Our water has never been this clean. We go through a lot of water in this house, so the filters don’t last forever, but the trade-off is knowing it’s removing 99.99% of TDS. That’s a level of clean you can taste (or, sometimes, not taste, more on that below). A lot of the complaints you’ll see online are legit, but if you do your own research, you’ll also find the reasons and fixes. For example, frequent filter changes are expected if your tap water starts high in dissolved solids. It’s not a flaw, it’s how the system works. Pros: Removes virtually all dissolved solids, water comes out incredibly pure Large dispenser size = less constant refilling Comes with a TDS meter, so you can check water quality yourself Customer support seems responsive if issues pop up Cons: ⌛ Filters don’t last long if you’re heavy water users (plan to stock extras) 🥛 Ultra-pure water can taste a little flat or “empty” without remineralizing Pro Tip: Because ZeroWater strips out everything, it’s worth adding a mineral concentrate drop back in. Without it, the water can taste (or feel) like nothing, it’s hard to describe, but it’s definitely different. With remineralization, you get the best of both worlds: insanely clean water that still tastes “alive.” Bottom Line: If you want your water as clean as it can possibly get, ZeroWater delivers. Just go in with realistic expectations about filter lifespan and consider remineralizing for taste. For me, the peace of mind is worth it.

Great water filter, has good water capacity and is solidly built. I have four of these ZeroWater filters, different types though, but they do a great job of filtering water, and use them when I travelling and where I don't have access to a decent Reverse Osmosis water filter. I use the small purtable ZeroWater filters when we travel overseas, so I don't have to worry about buying bottled water as you can't be guaranteed of the quality of the water, as many of these are just bottled local tap water.
