The science behind triple-filtered water

In the world of water filters, not all are created equal. Why have a single filter water filter system when you can have a triple-filter? Yes, some people use a water pitcher with a single filter. This may seem fine at first, but it gets tiresome (and costly) to frequently replace the filter. It also fails to address the more complex particles often found in drinking water.


With the goal of creating a more robust filtration system, the scientists at Coway have developed the Coway Aquamega 100 system with three filters, certified by the WQA.


Filter one

The Coway Aquamega 100 begins with a sediment filter. Its role is to remove the larger particle contaminants in drinking water. This includes sand, silt and small pieces of clay, among other things. The sediment filter is the first line of defense in purifying drinking water, as it removes the most coarse elements. Through this filter, turbidity, or the “cloudiness” in water, is already reduced.


Filter two

Once the larger particles are removed, the water flows into the second filter. This one reduces the smaller particles of contaminants, like chlorine, in drinking water.


This filter also houses the initial activated carbon filtering process. The carbon acts as a very fine net for tiny contaminants. This filter helps to reduce numerous potentially harmful impurities. For starters, the entire system eliminates lead, cysts and volatile organic compounds, all by over 99 percent.


Filter three

The third and final filter in the system creates the finishing touch for crisp, clean drinking water by eliminating any remaining odors or lingering foul tastes. A lot of this work has already been done by the previous two filters, and the post-carbon filter gives the water one final stage of cleanliness.


Together these three filters make up a water purification system that delivers safe, delicious drinking water to your home every day. The filters only need to be changed approximately twice a year. And because the Coway Aquamega 100 attaches to the kitchen faucet, you and your family can enjoy unlimited amounts of free-flowing water. (No pitcher refills needed.) It’s pure water for coffee, tea, lemonade—you name it—or just to quench your thirst.
