What experts liked

It also cleans most types of water and has an advanced 5-in-1 system that alkalizes and mineralizes water as well. Even though cheap, thus, this product will improve your quality of life.
- iExpert 99
This system has a simple setup, requires no electricity to operate and you can order replacement filters without a problem.
- Best Pickist
On the plus side, the water tastes great initially, thanks to the Maifan mineral stones used in filters. It imparts a balanced flavor to the purified water, making it taste like good quality bottled spring water.
- Diligent Chef
It removes harmful bacteria, contaminants, chemicals, and impurities, enriches the resulting water with essential minerals, and gives it bio-energy properties. The components are BPA-Free, and the system uses gravity to filter water, requiring no connections to the electricity or plumbing systems.
- Freshnss
It is one of the best countertop water filter because it can removes a variety of contaminants including chlorine, bacteria, and artificial chemicals. The filter system removes terrible odor and varies the Ph level to slightly alkaline. And unlike most other systems, the water filter will produce the necessary minerals to your water, leading to a delicious, spring water-like drink.

With Zen, there are no fake promises. You get what you see! The filter used in this system is guaranteed to transform your contaminants-laden city water supply into mineral enriched drinking water that tastes great.This is because the system works on a multi-stage filtration process which ensures the removal of harmful chemicals, sediments and other contaminants. It also achieves all 5 functions of purification, mineralization, filtration, alkalinization, and preservation.

With a 7 stage filter process, the Zen is for those who need heavy duty water filtration.Because it is so powerful, it is actually able to perform many different functions. It mineralizes, filters, preserves, alkalinizes and purifies. This makes it by far the most thorough countertop water filter.
- Mr Water Geek
The technology of this type makes the system to eliminate every impurity, chemicals, and any contaminant that render adverse effects your health when you drink water.
- KitchAndTub
The filter is made from ceramic. The filter can also eliminate chloride and increase the level of alkaline to make the water taste better and healthier for your body.

What experts didn't like

System is very slow.
- iExpert 99
Some users have tested the pH of their water after running it through the 5-stage filter and have found their water not to actually have an alkaline ph.This may depend on the acidity of the water that you start with, but realize you are not guaranteed an alkaline level.
- Best Pickist
The system also takes a very long time to filter the water. The ceramic dome filter at the top of the device is also prone to cracking. Make sure the device in a shadow and you might be quite satisfied.
- Diligent Chef
The only weaknesses this filter seems to have are the fact that it needs frequent cleaning, boiling of the Mafia stones, does not remove fluoride, and is not fit for microbiologically unsafe water.
- Freshnss
From the above zen water systems review, it is clear how functional the filter is, however, it is not the best for water that is microbiologically unsafe. That means the system has limitations and will not clean all types of water. It will not remove fluoride and some other elements in your drinking water.
- Greeny Kitchen

The product is not NSF certified one.
- Water Gadget
It has no certification.

One reviewer’s chief complaint was not being able to buy the replacement filters on Amazon, which only offers filters from Purenex.
- Alkaline Water Machine Reviews
Mineral stones worked for a while, then started to give the water a fresh dirt taste.
- Water Filter Rating
The main issue is leaking or broken spigots (they just tend to not last very long and are costly to replace).
- Best Osmosis Systems
The unit will take some time to set up. At first, read the instruction carefully and then follow them. You need to boil and wash the mineral stones and run two cycles before consuming the water

- Top Water Filter
Very slow filtration rate.

- Water Softener Critic
The 7 stages take a long time to filter. You can expect to wait for about 2-3 hours for it to filter all the water.
- Mr Water Geek
Looking at the way the filter is constructed, it is cheap based on the plastic built.
- KitchAndTub
Made from plastic, the build of this product looks quite cheap. It is easy to assemble but it can also easily fall off when moved.
- Aquarium Adviser
Takes some time to setup – The unit requires you to wash mineral stones and run two cycles before you can actually consume water filtered by the Zen model.
- Soft Water Lab
Difficult to clean.

An Overview On Water Purifiers

For many homes, a water purifier helps keep drinking water safe and can improve the taste of the water. They can come in a couple of different forms: gadgets that attach directly to a faucet or the more popular jug purifiers that incorporate a filter directly into a pitcher or other receptacle. In the latter versions, you simply pour water into the pitcher, and it trickles through a filter into a lower reservoir, cleaner and tastier.

How does it do this? In almost every case, personal water purifiers use activated carbon to filter impurities. Carbon is very effective at catching a wide array of particles through the process of adsorption, catching chlorine and other unwanted substances in its pores. You can expect carbon filters to remove particles measuring anywhere from 50 micrometers down to .5 micrometers (a micrometer, also known as a micron, being a mere one-millionth of a meter). You might find that measurement in the specs of a purifier or even in the product blurbs if it’s an especially low number.

While carbon filters are great at removing most toxic particles and organic compounds, they’re not so good at catching minerals. Mind you, many of the minerals you’ll find in water are beneficial ones that the body needs, like calcium and magnesium. Even so, some purifiers opt for a secondary filter that can catch bad minerals and leave harmless ones in the mix.

So how do you know what kind of purifier you need? Since even the most thorough jug filtration systems won’t break the bank, it can be easy to just choose the most powerful one. But purifiers with extra layers of filtering can take time to push that water through the system or need more frequent replacements — a big hassle for large families on busy mornings.

It might be best to find out what contaminants are in your water to begin with, and you can do that by getting a water testing kit. They can be obtained from most state or local health departments. The website of the Environmental Protection Agency has a handy list on its website if you’re not sure who to contact first. Those kits will tell you the kind of substances that might be making your water taste funny (like zinc and chlorine), and raise a red flag for harmful and potentially fatal chemicals like lead.

The Water Purifier Buying Guide

  • Jug purifiers are super convenient and simple to maintain, and you can even take them on a picnic. It can be easy to forget that they’re even filtering your water, unless that process takes awhile. And with more powerful, multi-stage filters, it typically will. The process of purifying a full jug of water can vary widely between brands and models — anywhere from a minute or so to ten minutes or more. That can be a pain for impatient kids on the way out the door to school, but the trade-off might be worth it if you’re extra health-conscious.
  • One sacrifice for the convenience of a jug purifier is the relatively frequent replacement of the filter. As activated carbon accumulates particles, it reaches a point where it can’t adsorb any more from the water. A filter change will get your filter cleaning again, and how often that should be done can vary. About two or three months is standard for most systems. It’s a good idea to price the filters before you buy, since frequent, pricey replacements can more than offset the savings from a cheap purifier.
  • Space is a big practical concern for purifiers. Most of them are designed to fit snugly on a refrigerator shelf, though some compact models can be small enough to slide into the fridge door. That’s great when there’s not a lot of room, but of course, you can expect to fill it up more frequently.
