"I've been there, you've been there. Sink filters, under sink filters, endless pitchers. Brita, Pur, various generics. All make the water somewhat better, but do not make the water "good". ZeroWater does just that -- it makes the water "good"For ten years I've purchased ZeroWater products and I cannot accept anything else. It's one of those products -- once you start using it you realize how less than stellar everything else you've used before was in comparison. ZeroWater takes bad water and makes it taste better than bottledI live in an area with awful water and this house has awful old pipes. The tap water here tastes very similar to how a toilet tank smells - somewhat musty, somewhat off. It reads in the high 200s on the included meter. ZeroWater takes that down to 0 and removes the awful taste completely. If you put this in a bottle and told me it came from an industrial purifier I'd believe youEvery friend I've introduced to ZeroWater has been shocked by the difference coming from other brands. In my opinion Brita and Pur still leave lingering traces of nastiness even though they filter the harmful stuff out. You can make water safe without it tasting good -- ZeroWater makes it safe and good unlike other brandsThis large dispenser with two filters works wonders in solving how quickly my family goes through water -- not only does it filter faster than regular single filter dispensers, it manages to hold over three gallons. I can pour a gallon at a time up top and will have plenty of water without needing to sit and refill it constantly. It takes care of my only complaint -- the other previous ZeroWater products needed babysitting somewhat to fill to a usable level. If you have room, this is the one you wantI was concerned about filter lifespan and needing two filters until I realized each filter is effectively doing half as much work. I will gladly pay for a two pack of filters since this purifies so much faster than the others in this rangeHaving the pull lever instead of a button on the dispenser nozzle is very much appreciated as well. I had a smaller version that only had one filter and a push button that required you to stand there and hold it. This is so much easier for people who may have difficulties like arthritis or other issues. Pull the lever down, it fills. Push the lever back up, it stops. It's as easy as flipping a light switchI find myself drinking more water now that I have this dual filter tank. I keep a gallon pitcher on standby and can quickly fill this to capacity -- I really cannot give this dispenser enough praise. They really listened to their audience and fixed any complaints I would have had with previous models being slow or annoying to use due to needing to hold a buttonI'll borrow a quote from the old Packard car company, "Ask the man who owns one". I own one -- this is the one you want. Once you get used to the convenience there is no going back"

The water taste so clean! I have had the zero water 52 cup jug for a few months now and I am really impressed with it! It holds a lot of water so for a family of 6 this is ideal for us. It’s easy to refill and the filters are lasting us a little over a month. Keep in mind when your water starts to taste like lemons it’s time to change your filter. But it really does work and keeps the water at zero. The thermometer it comes with is super easy to use.down to earth reviewer
What you will read below is the result of my extensive search for water as…
What you will read below is the result of my extensive search for water as healthy and hidrating as possible. Initially, that research led me to ZeroWater.ZeroWater Filters comply with IAPMO. It means that IAPMO has verified that ZeroWater Filters substantially reduce or eliminate contaminants claimed by ZeroWater. IAPMO confirms that ZeroWater Filters ~which are used in this 'ZeroWater 52-Cup Dispenser'~ remove forever chemicals a. k. a. PFOA and PFOS, lead, chromium, mercury, chlorine, pesticides, and dissolved minerals.However, ZeroWater Filters will NOT remove e.Coli, Salmonella, Cholera, Giardia, or any pathogen. In other words, ZeroWater Filters will not make safe water which is unsafe. ZeroWater Filters are intended for water which is already potable.There are two sensible options for unsafe water or water suspected to have pathogens. OPTION 1 is to boil the water. Once water reaches room temperature, it should be run through ZeroWater Filters to remove the substances listed above making water much safer and giving it a better taste. OPTION 2 is to run the suspicious water through a highly effective filter with a sensible price. Its name is Sawyer. It is a small size filter that filters water slowly, but the little guy removes 99.99% of bacteria such as e.Coli, Salmonella, Cholera as well as 99.99% of protozoa such as Giardia. In addition, Sawyer removes 100% of microplastics. The water coming out of a Sawyer Filter should be run through ZeroWater Filters to further remove the substances listed above.My research led me to one major step worth considering: 'Better Hidration.' I read the work of scientists who unveiled the truth about widely claimed benefits of 'Alkaline Water.' They assert that such claims are "anecdotal;" and therefore, they cannot be proven by scientific means. There is only one benefit ~they point out~ that can be proven by scientific means; and that is that water with a pH of 8 1/2 to 9 hidrates cells of our organs ~and those of our pets~ more efficiently than tap water with a pH of around 7 1/2.I learned that 'Invigorating Life' offers NSF Certified Filters that bring water pH up to 9. Therefore, my final conclusion is that running water through a 'Sawyer Filter,' then through a 'ZeroWater Filter,' and finally through an 'Invigorating Life Filter' will turn already potable tap water into a truly healthy and hidrating water.Filters that I mentioned in this review are available here at Amazon.jesus saved me

I was like, "No way you get 0 PPM out of a consumer, non-pro filter". I decided to order it to test it myself.Water in Toa Baja, PR reads around 175 PPM straight out of the tap on the more accurate HM Digital TDS meter (sold by Amazon), which is good-ish in the grand scheme of nasty tap water.I followed the assembly instructions, which you should always read to be sure and not assume, and put it together. Inside the filter reservoir, it reads down to around 115 PPM, and around 109 PPM on the included TDS meter.Filtering speed is slow, but way faster than I expected for a drip filter. From empty, you will have a full drinkable glass in a minute or two depending on the water quality. The whole thing gets filled quicker than it looks. Work on the kitchen while it filters.Results? 0 PPM on the included TDS meter. 0 on the HM Digital one, too. 😳I drink it up and that's a whole 'nother different taste, smell and mouthfeel.Even bottled water has a flavor we get used to and prefer. Not this. Reminds me a bit of how Glacéau smartwater feels in the mouth.If you are used to "tasty" water, this will taste flat to you, almost like bottled distilled water. It's very "empty-feeling" in the mouth and initially unsatisfying, but your tastebuds get recalibrated quickly after several gulps.Build quality-wise, time will tell how long the plastic integrity lasts, but it only has one moving, spring-loaded part, which is the spout you insert and it remains in place by o-ring pressure.With sunlight avoidance and consciously careful handling, these plastic parts should remain leak-free and not break. I will downgrade the rating if they do. For now, I give it five stars. ⭐⭐⭐⭐⭐adam

Update 3/15/24: I wanted to add some additional information and some photos to my review. (See below for initial review). A little over a month after getting this, it did require a filter change. As some other reviewers have mentioned, there was a slight fishy smell to the water, and was leaving my dishes with the same smell. The PPM meter was only reading .5 at this point, even though it said to change the filters at .6. I also started to refill it with the water from my PuR instead of the tap, as the packaging had a chart showing that water with lower PPM minerals will help the filters last longer, and should give me 25-40 gallons per filter instead of 15-20. This takes longer to refill obviously, but it's not a big deal.It also does something funny when making ice (see photos). I'm making an educated guess and assuming because there's no minerals weighing the water down, it expands much more than harder water would, and since it has nowhere to expand but up, creates large spikes on top of the ice cubes. I was pretty entertained by this when I opened the freezer to see this.I'll be buying the filters in sets of 6 or 8 in the future, as this brings the cost from $15/ea down closer to $10 each. Still loving this water filter!Original Review:I'm the kind of person who absolutely loathes doing dishes, but living in an apartment with no dishwasher left me no choice, until I got a small countertop dishwasher I can fill with water from the top. I found, however, that using tap water, which is very hard in my area, left a ton of water spots on my dishes. After switching to using my PuR water pitcher to fill it up, I did notice less spots, but it took forever to refill and wait, over and over again, and still wasn't leaving my dishes spot free. Knowing the hard water in my area isn't good for my dishwasher, I needed to find another option.After looking at in-line, under sink water filters and deciding against going that route, I picked up this ZeroWater countertop dispenser. Not only does the water taste fresh and clean, but when using it in my dishwasher, it left my dishes COMPLETELY spotless after they dried. With no dissolved minerals in the water, it actually caused my dishwasher pods to create so much suds that the rinse cycle didn't even wash it all out. I had to switch to liquid detergent, which works great now without needing the additional softeners that the pods contain. I also no longer have to wait for the PuR pitcher to refill multiple times to fill my dishwasher with the 5 liters it requires, so it's saved me a bunch of time already.When testing the 3 water sources with the included water testing device, my tap water was at 302ppm. After filtering through the PuR filter, it was reduced to 185ppm. Finally, testing the water from the ZeroWater dispenser, it sat at 0ppm. Exactly as advertised.Over just the past few days this filter has given me great tasting water that I've used for ice, cooking, drinking and filling up my dishwasher without having to wait forever between refills.I haven't had this long enough to comment on filter life, but the filters are much larger than either the PuR or the Brita, and having 2 helps the water filter much faster. Being that it reduces much more than both of those brands, I wouldn't be surprised if they don't last as long, but it's a worthy trade off imo as long as I'm not changing them weekly like some reviewers here have complained about.For now, I would definitely recommend this water filter to friends and family!ccpt

I am currently living in a rental home and do not have an undersink water filter device so had to purchase a counter top form. This ZeroWater filter pitcher dispenser is wonderful. It doesn't take up too much counter space, is easy to use, filters extremely well, and the water tastes good. I wanted a ZeroWater filter because of its ability to filter out PFAS along with other impurities.What Customers Talk About
