Top Reverse Osmosis Technology

This system uses the Reverse Osmosis process where water is forced through a semi-permeable membrane, leaving unwanted pollutants and contaminants behind. A Reverse Osmosis unit will provide you with clear, clean, fresh drinking water. The process uses no chemicals or electricity. It's the most effective technology known for the improvement of drinking water.

System Without "GOLD SEAL" certified to "NSF/ANSI Standard 58" is Only Second Best


GOLD SEAL Label "Must" be On System

The Gold Seal means the system has been tested and certified by the WQA (Water Quality Association) for performance, reliability.  WQA is a not-for-profit organization.

Gold Seal Product Certification Program - Why is it important?
To help consumers choose quality water treatment products,
WQA developed its Gold Seal Certification Program — issuing the first Gold Seal in 1959.

WQA only awards the Gold Seal to those systems, components, and additives that meet or exceed industry standards for contaminant reduction, structural integrity, and material safety. Customers can easily identify WQA Certified products by looking for the Gold Seal Mark.

Gold Seal certified by the WQA  for performance and contaminant reduction to NSF/ANSI Standard 58.

What is NSF
NSF is a public health and safety company. You can visit for more information.

NSF/ANSI Standard 58: Reverse Osmosis Drinking Water Treatment Systems
This standard was developed for point-of-use (POU) reverse osmosis (RO) treatment systems.  Standard 58 includes contaminant reduction claims commonly treated using RO, including fluoride, hexavalent and trivalent chromium, total dissolved solids, nitrates, etc. that may be present in public or private drinking water

Don't Risk Your Family's Drinking Water

You do not want to compromise your drinking water.
There are many systems on the market. How do you know that the material used is safe for drinking water? How do you know whether the system is reliable? How do you know whether the filtering mechanism works as it claims? These are critical questions when dealing with your family’s drinking water. You can rest assured when your system is labelled with the GOLD SEAL certification. It is very difficult for water purification systems to be certified because the process is very expensive and the systems need to pass many strict tests by third party companies.

Buyers Beware of "to" vs. "by"
1) Many companies label their systems as "Tested and Certified to NSF/ANSI 58".  The "to" means that any outside company or individual can test products to NSF/ANSI standards.
2) This is VERY different from "Tested and Certified
by WQA to NSF/ANSI 58".  The "by" means that the test is performed by WQA organization.  Therefore, it offers you the highest and best protection. Probably, fewer than 1% of the drinking water systems in the world are "whole system" certified by WQA. When it comes to your family's drinking water, don't take any chances.

This Whole System is Tested and Certified "BY" WQA

Buyers Beware of "Components" vs. "Whole System" certified. 
Learn the difference between these
a) Components tested and certified.  This means that the system is build using all or partial certified components.  However, there is no certification on the "whole" system and no guarantee that the system work as a whole. 
b) "Whole System" tested and certified.  Whole system tested and certified is highest certification that you can get.  This is the best guarantee and protection that you can get to ensure that you are high quality reverse osmosis system.  Only "whole system" that is certified, such as our GTA - RO Platinum, will have a GOLD SEAL sticker on the system.

Life is good.

"GOLD SEAL certified"


 Alkaline (pH) + Mineral Option:  Add Minerals Back Into Water and Increase pH                                      

Most people who are looking for the best and healthiest drinking water will add natural minerals back to their reverse osmosis water.  All reverse osmosis system, regardless of brand or type, will produce water of approximately 6-6.5 pH which is a little acidic.  Our AlkalinePlus can enhance the pH of your RO water close to neutral - approximately range of 7 - 8 pH, depending on water source.  This makes the water a perfect Natural Alkali Calcium Ionized Water, providing you one of the best complement to reverse osmosis water.

Produces perfectly ph-balanced alkaline water, helps minimize the fluctuations of your body's pH level.

Turn acidic drinking water into alkali calcium ion water.

The filter contains natural calcium, magnesium, sodium, potassium ions which can be absorbed 100% by the body.

Reverse Osmosis System VS. Whole House Filter

A Whole House Systems
will likely remove less than 20% of contaminants in tap water.
Reverse osmosis systems can remove up to 99.9% of contaminants.
They are different technologies for two different usages. One of the biggest misunderstandings in the market today is consumer thinking that a whole house filter system is designed for drinking water. It is not!

Fluoride & Uranium Removal
Removes fluoride and uranium from your water. Fluoride has been found to be very dangerous to the human body.  Uranium is a very difficult contaminants to filter out, consumers shall monitor and test their water supply shall they have uranium problem.

500 Contaminants in Tap Water
A Shocking Discovery

Drinking tap water is like pouring chemicals and other contaminants into our body. It is like smoking which will not kill us immediately, but we know it is very detrimental to our health and irreversible.  Children are more vulnerable then adults since they are growing and have a smaller body mass. What are you doing to protect your family’s drinking water?

 Don't Risk Your Family's Drinking Water

The Environment Protection Agency compose a list of contaminants in drinking water that are health hazardous.  When it comes to water pollution, the tap water in Canada is not that much better than that in the US.   

Drinking Water Contaminants List: Shocking!

It is no longer the question of what is in our tap water, it is now a question of what can we do to protect our family's drinking water.

Health is Wealth, Live a Healthy Lifestyle

Our health is our wealth. The human body composes of 70% water, and needs 7 glasses of water everyday to prevent dehydration. Tap water taste very bad and there are all kinds of waste and contaminants in the water.  To drink tap water is to pour chemicals into our body

Most people do not drink 7 glasses of water per day and get dehydrated without knowing because they avoid drinking contaminated tap water and high sugar content soft drink. Children are easier to get dehydrated because parents tell them not to drinking dirty tap water.  Your family will live a more healthier lifestyle because our Reverse Osmosis water is so tasty, you will drink more water.

Life is good

Changing Filter - Wrench vs. Quick Twist Off Model
If you are a handy person, then changing filter with the wrench would be very easy.  Just shut the water and slide in the wrench to twist off.

However, if you are not so handy or do not want to use too much force, then you may wish to consider the "Quick Twist Model".  Just shut of water, and easy twist off by hand easier than changing a light bulb.

Well Water or Lake Water (optional)

It is recommended that a UV Light be added to any drinking water purification system that draws from a well or a lake.  Well and lake water is considered uncontrolled water source.  Bacteria and viruses can suddenly grow because of nearby contamination from animals remains or waste.  Protect your family's drinking water with a UV light.

This option is available for selection in the shopping cart.  Just change light for $99/year and clean the glass tube every year. The light bulb and parts are popular size and sold in most places.

Good-bye to Costly Bottled Water
Say good-bye to your bottled water for two reasons. 
1) A jug of bottled water is about 20 lbs, therefore don't break your back lifting it. 
2) Delivered bottled water is about $7.99 per jug, that is expensive. A family of four needs minimum 3 jugs per week for all cooking and drinking and that is $1294/year.  But our reverse osmosis system will only cost $0.25 / day to operate and your family gets all the pure drinking water you need. 


Our system costs you about 25 Cents/day...
            ...less than the cost for a cup of coffee...

$0.25 / Day
