Just as you need a well-balanced diet to maintain a healthy lifestyle, you also need fresh clean water to go along with it. The quality of the water you consume everyday goes a long way to determine your quality of life.

Unfortunately, some water sources contain a lot of contaminants which make them unsafe for drinking. This makes it necessary to provide an extra means of purification for your city water supply. And one of the best ways you can achieve this is through the use of a high quality water filter.

The Zen Countertop Water Filtration System is your best take if what your desire is an affordable filter system that can produce fresh clean alkaline water. Equipped with a 5 stage water filter that ensures removal of contaminants and chemicals, this unit comes as a standalone filter that doesn’t require electricity to function.

So feel free to go for any one you think will suit your family size.

Each filter that comes with the Zen Water System has a filtration capacity of 500 gallons, after which it will need replacement.

No doubt, this is one product that can give you the best value for your money!

Special Features

Advanced Filtration technology

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.

Natural Filtration

The Zen Water System provides excellent purification of water supplies in urban areas. This product is mainly developed to remove chlorine, VOCs rust and sediments, which are major impurities in city and municipal supplies through the use of natural water-filtration materials.

This makes the system an ideal solution for producing clean mineralized water in your home all through the year.

Easy Installation

Installing many whole house water filter systems usually present a challenge for many homeowners. However, this is not the case with the Zen Water System. Even if you don’t have any DIY skill set, your first time with this system will make you feel like a pro because it’s going to be easy like ABC.

There are no electric lines to fix up or any of those difficult things required to be done to get some conventional filters running. No need to call in the plumber.

A detailed manual with step-by-step instruction is provided to make the installation a breeze. If you are patient and careful enough to follow through, you should be done with the whole set-up within few minutes.

Cost Effective

When using the Zen Water System, you won’t need to purchase extra water. All you need to do is to fill the tank with tap water and let the filtration and mineralization process begin. This unit doesn’t require electricity to run.

You don’t have to spend money in buying heavy plastic bottles. This saves you money on water and energy bills, as well as the stress of carrying heavy bottles here and there. When you think about it, there’s no better way to enjoy fresh clean water with less hassle.
