This article was originally a glowing review of this product but has since been updated to reflect that I no longer recommend ZeroWater.
Having personally used ZeroWater for over 1 year (and changed the cartridge as instructed), I encountered the following problems:
The cartridge and therefore water eventually starts to smell like mould. My family members who also purchased this (based upon my recommendation) also had the same problem so I know I didn’t just get a faulty device.
The water starts to taste weird as a result too.
Although the water has zero TDS (total dissolved solids), it might still have other ‘non-solid’ contaminants. For instance, I noticed that it didn’t do anything to fight limescale and my brand new kettle is full of white scales.
It is for this reason that I started using AquaTru, which solved all of these problems and I’ll talk more about this later in the article.
But first thing’s first,
this Article is a REAL Review From Personal Experience.
I purchased ZeroWater (ZeroWater 7 Cup ZP-007RP 1.7 Litre Blue Water Filter Jug) from Amazon on 19 February 2019.
I used it for approximately 18 months before having to re-consider whether or not it was worth continuing. I initially had a very good experience with it so recommended it to family members to purchase and in the end 2 people in my family also purchased it.
This article reflects my direct experience using this product along with feedback from the family members who also purchased ZeroWater filter based on my original recommendation.
What is ZeroWater?
The ZeroWater filter jug is sold as the only water filter that removes more than 99% of dissolved solids from your water with a 5-stage filtration system.
The amount of solids dissolved in tap water varies throughout the United Kingdom. However, each Zero filter removes 18,000 milligrams of dissolved solids, which in theory makes the water purer.
ZeroWater’s Biggest Selling Point
The biggest selling point of the Zero Water filter jug is its many layers of filtration. This means that it is able to remove a lot more than other filter jugs like Brita.
ZeroWater’s first filtration state is a layer of oxidation-reduction alloy and activated carbon filtration that removes the taste of chlorine that comes with tap water.
The ion exchange stage removes almost all dissolved contaminants and heavy metals. Especially those that might still appear after public water system treatments. This includes traces of lead, nitrate, aluminum, zinc and lead.
There are three extra stages that remove other bacteria. These stages are to make sure that your water is fully treated so that it produces a “000” reading on your water test kit (i.e. the (TDS meter).
There are third party tests and certifications to prove that it can reduce things like chloride, fluoride, chlorine as well as other inorganic compounds. Also, the makers claim that it is the only filter to reach the FDA (Food and Drug Administration) requirement to have a TDS content of 000 to 01 ppm.
Q: What Does ZeroWater Remove?
A: Everything you want it to!
This is sold and promoted as the only water filter jug that can remove almost all dissolved solids from your water. It has an impressive 5-stage water filtration that is certified to reduce both chrome and lead.
You should consider this to be important because dissolved solids enter the water supply through old pipelines. These can be full of heavy metals, hormones, hard minerals (like calcium and magnesium, fertilizers and pesticides.
ZeroWater is equivalent to purified bottled water because it can filter TDS by 99%. TDS stands for Total Dissolved Solids and refers to the total level of contaminants in your water.
Certified to NSF/ANSI Standard 53 abd certified BPA-free by LG Chem (2016).
ZeroWater Tests and Certifications
ZeroWater is certified to reduce lead. This is to standards set by UK water service providers. According to other independent tests, ZeroWater filters are capable of reducing the level of pharmaceutical products that’s in your tap water.
- An EPA (United States Environmental Protection Agency) certified Fluoride Reduction Lab tested Zero filters to show that it reduces fluoride by 99%.
- They are NSF certified to reduce Chromium 6 by 99.7%.
- Tested for arsenic reduction. An independent EPA-certified laboratory says they are able to do this with a total reduction rate of 99%.
How Long Does A Zero Water Filter Last?
A small feature of ZeroWater is that the acidity of the water changes slightly when the filter is about to expire. This is to alert you that it is time to replace the filter.
You should replace the water filters immediately when your water test meter (included for FREE) reads above “006”.
Especially if the water has a sour taste, a fishy odor, or your water quality meter displays more than “006”. This is all necessary to continue to enjoy the positive health benefits of ZeroWater.
ZeroWater VS. Brita
Brita is cheaper but ZeroWater eliminates far more than Brita.
There is almost no comparison between the filtration capacity in the case of ZeroWater VS. Brita:
- ZeroWater eliminates 99.6% of the total dissolved solids compared to Brita, removing only 49.6%. The table below gives a clear indication of how much more Zero is able to remove when compared to Brita.
|ZeroWater 5-Stage Filter||Brita Maxtra Filter|
|TDS Removed: 99%||TDS Removed: 50%|
|Fluoride: 99%||Fluoride: 14%|
|Chloride: 99%||Chloride: 29%|
|Lead: 99%||Lead: 66%|
|Chromium: 99%||Chromium: 32%|
|Asbestos: 99%||Asbestos: 55%|
|Nitrates: 99%||Nitrates: 1%|

Is ZeroWater WORTH It?
My original answer was “yes” but is now a definitive “no”.
The bottom line is that the water starts to smell and taste bad after a while. The smell is similar to mould. I followed all the instructions and changed the filter cartridge when it was time to do so.
Family members that also bought ZeroWater (based on my recommendation) also had the same issue so I know I didn’t get a one-off faulty device.
This is such a shame because ZeroWater is very affordable and the free TDS meter (that comes with the jug) is a nice touch. Seeing the TDS meeter read 000 after replacing the filter was very reassuring but I have since learned that TDS-free does not mean contaminant-free.
Also, it does nothing for limescale so your kettle will still be full of white crystals.
I later moved on to AquaTru, which I am very happy with. It is much more expensive but a powerful machine that treats everything missed by ZeroWater and the water never tastes weird even when the cartridges need to be replaced.
AquaTru Turns CocaCola Into Clean Drinking Water
The BEST ZeroWater Alternative? AquaTru.
The system has a multi-cup dispenser that delivers filtered water at the touch of a button.
It is easy to set up and install straight out of the box.
While its filter cartridges are also very easy to remove and replace.
