Bad filters

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full
I have been using the zero pitcher and filters for a long time now and have had pretty good luck. But now the filters that I purchased at the supermarket are bad. Bad tasting and smelling. Just one more expensive item to throw away. Oh well, I should have known it couldnt last. On to another brand.

Poor filter construction & Terrible Customer Service

Zerowater - Poor filter construction & Terrible Customer Service

Upon drinking the water from pouring into a glass I noticed strange crystallised particles in my mouth. Upon further inspection it seemed these particles had broken through the filter into the base of the pitcher.

I became increasingly ill (gastric) and needed medical attention. I immediately contacted the company explaining the situation and asking for help/support to pass onto my doctor. Their customer team (Erik) ignored several attempts at communication (email & phone).

Accordingly, I am now going through professional legal advice! I will never use this product again and advise anyone to avoid at the expense of your health.

Filters take WAY too long

stars-rating-full stars-rating-full stars-rating-full stars-rating-full stars-rating-full
Read complaints (long after purchase sadly) about the filters often taking WAY too long to pass the water through. On our 2nd filter now and same as the first. Read online about the issues with bubbles and how to help. But tapping the filter only works for a very short period of time. We may go back to our PUR filter if we can't get this to work well more consistenty.

About the sour/acidic taste of ZeroWater filtering system

Updated by user Dec 20, 2016

OK, after a year and half of continuous experience on the Zero Water filter and browsing all replies following my review so far, I think I have a deeper understanding of the "problem" of this product.

I mentioned that the TDS reading of the tap water in the city I was li...

Original review May 23, 2015
I am a chemist and a polymer expert. I know what ion exchange is. I had the same sour/acidic taste experience with ZeroWater. It seems to me a design problem of this product.

Background 1: What does a filter capture?
Many other branded filters, such as Brita, DO filter some harmful organic chemicals in water using activated carbon. They don't do anything with the salts in water (not only the sodium chloride used in cooking). General salts in water are not harmful, but they don't taste good at a high concentration. ZeroWater captures cations and anions in water using the ion exchange technique, so that the salts are filtered.

Background 2: What do you know from TDS number?
The TDS meter coming with ZeroWater tests the conductivity of water. That is, it only measures the concentration of salt/ion in water instead of all solids, and estimates the amount of total dissolved solid in water. The water with a 0 reading on the meter can still contain some organic chemicals. Anyway, it's reasonable to believe the total solid left in water is very close to zero based on the so-claimed 5 stage filtering technique including an activated carbon layer. However, a totally pure water is not good to health in fact. If you read a TDS value of 30 from a bottled spring water, it doesn't mean the water is not good. Instead, the water contains some minerals/salts needed by your body. Sometimes I added a small fraction of Brita filtered water in the ZeroWater to tune it to below 50 TDS.

Problem of ZeroWater:
After flushing the ZeroWater filter I started to enjoy the filtered water, which was much cleaner than the tap water (TDS around 700). However, after about 5 gallons of water were filtered, the filtered water turned bad and tasted extremely sour/acidic as many people had experienced. I noticed at that time that the flow rate of the filter was faster than before and some gas bubbles came out from the orifice at the bottom of the filter. The sour taste indicated there might be still a large amount of hydrogen ions available in the filter, and the filter should still have a considerable lifetime. It seemed that some structure in the filter was crushed because of the build-up of filtered substance or increased pressure inside, so the chemical holding hydrogen ions leaked out. The flow rate might be much faster due to the damage, taking out the small amount of air that would be otherwise locked inside the filter.

Hope this comment is useful to both the users and the engineering department of ZeroWater.

Current thought is your body does not need the minerals in tap water. Many sources claim this is true. I imagine this information is well outdated.

i stopped using zero water filter

I would like to know if there is an acidic taste to the water through ZeroWater filtration, why is it reading at zero. I drank more than a few sour water bottles thinking it was okay!!

going back to bottled spring water...... *** I thought I had something here.

Great Info...thanks

I get the worst heartburn after drinking water from the Zero water pitcher. Does anyone else have this problem?

Guest

Yes. After less than 2 wks, the filtered water is sour. Im very concerned about the ph level of this water if the filter is no longer doing its job at full capacity.

I have had heartburn since I started drinking zero water..I think it has caused damage to my stomach and don’t know what to do to make it go back to normal..totally lost my appetite too..these should be taken off the market they are dangerous

Guest

I have the same problem. New filter lasts 2 weeks before water turns really sour. Very unhappy, waste of money!

Guest

My tap water TDS is 18. After 3 uses of the brnad new 10 cup unit, the water tastes like lemonaid. Wrote to Zerowater to see the response.

Guest

We have had our Zero water filter for 2 weeks and the last 5 days the water has been awful . One day its acidy/lemony and the next its like I drank from the Ocean.

This thing is terrible . I am going back to my faithful Britta.

Your customer service representative didnt know when youre supposed to change your filters, I find that unbelievable Ive been using your product for quite a few years. I stopped because the water started to have like a lemonade taste almost to it the other thing I want to know is if your filter filters out PFAs that are in the water system of most municipalities today.

Filter problems

Seems to get air trapped in filter constantly, have to drop pitcher on counter to release the air pockets trapped inside. If it weren't for that problem I would continue to buy, but this happens all the time. Guess Ill go back to regular tap water.

Filter issue

After filling the Zero Water container the first time, with the second refill, the water did not filter through and stopped. I pleasantly called Customer Service to get some suggestions as there were no FAQs that dealt with this issue.

Customer Service immediately understood my filtration issue and made different suggestions to help with the two types of water containers I had purchased.

One worked and the other did not; however, I did learn what I was to do. I was told to squeeze the filter with 1 inch water in the top to get bubbles on top. If that if that did not work I was to roll the filter to loosen on it's side to loosen the filter pieces to allow water to flow freely. I got one of two filters to work but was offered a replacement filter for the one I was unsuccessful with.

A nice interaction, and I wish this information was included in the instructions/FAQs.

I was just happy to get someone on the line quickly who was able to help me. Thank you.

At the price they charge for their filter you would expect the filter not to add anything to your water ! I tried 4 different filters one after the other and all of them added carbon in the water. You could see it at the bottom of the tank. Ic you believe it look at the picture.
