Today we’re going to be reviewing the Zero Water Filter to see how it matches up to other similar home water filter products out there right now.
There are many different reasons why you should avoid drinking tap water. Of course, the level of the problem depends on where you live in the world, but it’s generally better to filter your water than drink it right from the tap.
Home water filters offer a simple solution, you simply fill up your jug and wait for the clean filtered water to come through the system.

The Zero Water Filter is already a big seller in the USA, but it’s only recently been made available in the UK.
The purpose of this Zero Water Filter Review is for us to take a detailed look at this home filter from all angles to see where it stands in comparison to the similar products out there such as Brita.
Brita is the market leader when it comes to water filters in the UK, and so does the Zero Water Filter offer serious competition.
We’re going to take a detailed look at the Zero Water Filter from all angles to see where it stands.
So, with the introductions out of the way, let’s start taking a closer look at the Zero Water Filter.

Zero Water Filter – The Basics
As we’ve already mentioned, the Zero Water Filter has been available in the US for some time, but they have now also entered the UK market.
The filter jugs start at around £24.99 on Amazon in the UK. There are more models on sale in the US but we presume these will eventually be made available in the UK too.
We were sent a 12-cup ready-pour pitcher complete with a filter cartridge and a Total Dissolved Solids (TDS) measuring tool (which is really cool).
We’ve been using the basic UK version of Brita for most of our life, so we were keen to see whether the Zero Water offered a better option.
The first thing that strikes us about the product is that it’s not quite as pretty to look at as Brita’s latest jugs. It’s got a more industrial feel to it and it’s a bit more fiddly to refill.
However, the main thing to be focusing on with a product like this is the actual water quality it produces.
So, let’s now take a closer look at how this hi-tech system works.
How Does The Zero Water Filter Work?
The first thing to explain is the use of the TDS measuring tool. You simply place it in a glass of water to see the total amount of dissolved solids present.
In case you didn’t know, Total Dissolved Solids refers to the number of compounds such minerals, salts and organic compounds that are dissolved into water through contact with rock and other surfaces.
Some of them are good (like minerals) and some of them are not so good (like metals such as lead and mercury).
We all need some minerals from our water, but the problem is that most tap water also sometimes contains other stuff that’s not good for us, such as chlorine and lead.
The Zero Water filter is highly impressive when it comes to removing impurities. It uses a five-stage filter to remove 99.6 per cent of all dissolved solids and 99 per cent of all Fluoride to deliver a truly pure tasting glass of water.
The brilliant part is that you can see for yourself.
When you put the TDS measuring tool in a glass of Zero Water, it comes up with a 000 reading! We tested this against regular tap water (in London, UK) and our Brita Maxtra filtered water and you can see the results below.

Tap Water vs Brita vs Zero Water
As you can see for yourself, the Zero Water filter indeed produced a 000 reading on the TDS measuring tool as promised.
Tap water came in with a reading of 348 TDS, while our Brita filtered water produced a reading of 273 TDS.
The proof is simply in the numbers, the Zero Water filter basically removed all dissolved solids to produce a clean glass of filtered water.
The water tastes, great too. The only thing you’ll have to bear in mind is that it may be worth remineralizing the water with a pinch of salt of something similar, as it will not contain any minerals after being filtered.
How do you know when to replace your Zero Water filter? Simply when your TDS tool starts to show numbers above 000.
The Positives
• Effective – The Zero Water filter works incredibly well to remove most impurities from tap water. We were very impressed to see the difference between the water produced by Zero Water and our trusted Brita filter.
• Great Taste – The water really does taste great, and it’s like drinking bottled water. It tastes far better than regular tap water or our Brita filtered water in our humble opinion.
• Price – The price tag for the jug is affordable. The replacement cartridges are significantly more expensive than Brita, however. One replacement cartridge currently costs £19.99 in the UK, although they offer discounts if you’re buying more than one. We will have to see for ourselves how long one cartridge will last for.
The Negatives
• Design – We must say that the filter’s design is not quite as neat and tidy as Brita’s latest jugs. It’s also a bit disappointing that there isn’t a premium glass jug offering, as we would always purchase a glass jug over a plastic one.
• Slower – Because it filters better than other options, it’s a bit slower than a Brita filter. The bigger jug makes up for this though.
Zero Water Filter Reviews
We took a look on Amazon.com to see what real customers were saying about the Zero Water filter.
At the time of writing, it had an average rating of 4.2 out of 5 stars from more than 230 reviews.
One happy customer left a five-star review and said that they were highly impressed by the taste and quality of the water.
However, one more negative review came from someone who said that the cartridge only lasted them a fortnight, which is not ideal.
Anything Else To Consider?
As mentioned above, because Zero Water removed most impurities and dissolved solids from the water, you may have to look at a solution to remineralize it to ensure that you are hydrated properly.
Review Conclusion – Final Thoughts
That brings us to the end of our Zero Water Filter review.
We have been highly impressed by this product and the fact that you can clearly see it outperforming market leader Brita thanks to the TDS monitoring tool.
The only drawbacks are that the cartridges are expensive, the design could be better, and it’s a little bit slower than other options.
However, we are big fans of it and will continue using it.
