Healthy Mineral Water for You & Your Family

We don’t just sell filters, we also evaluate them! We conduct a complete laboratory analysis on every filter we sell, to make sure it’s good enough for your family’s needs.

Water is the most basic necessity of life. But there are many contaminants in it that have adverse effects on our health. It is so important to know how to get pure water for our consumption and environment.

We offer high-quality water filtration systems that meet the National Safety Standards. Our Institute is one of the few certified, EPA-approved systems in UK.

Bottled water delivery is a great way of saving money — having a constant supply means you never have to worry about running out when it’s inconvenient (late at night or when it’s raining). You don’t have to worry about where your water comes from anymore — we’ll deliver bottled water right to your doorstep, with no commitment and free shipping! Never worry about not having any on hand again.

Why Choose Us

We Are Focused On Keeping Your Water Clean

Your water should be clean and pure. Our water filtration systems give you peace of mind and confidence when it comes to the safety of your family and your health. We have now reached a point in history where more than half of the world’s population are living without access to clean water, and some public water supplies contain chemicals and minerals that can be harmful to your health.


Contaminants Elimination

A purifier that lasts a lifetime is worth the investment. The lifespan of our filters is 10 years or more! Just replace the filter cartridge every 6 months or so and keep on drinking pure, clean water without fear of contaminants.


Waterless technology that's easy on the environment

UV-C light is one of the safest ways to purify water because it doesn't use any chemicals or filters that could pollute our earth!

Our Services

Contaminants Removal

Without a doubt, the amounts of contaminants a water filter can remove is essential when deciding on its efficiency and reliability.

Flow Rate

The flow rate represents how much water runs at your tap in a certain amount of time and is measured in gallons per minute.

Filtering Technology

The type of technology used by a certain whole house filter says much about its performance.

Filter Capacity

It’s also useful to analyze how many gallons of water the filter can handle before requiring a cartridge replacement.


House filtering systems include a UV light that can kill dangerous viruses in the water or a water softener that can solve the hard water issue.

Ease of Installation

As a whole house system is installed on the main water pipe, it’s important to find the model that doesn’t require too much plumbing.
