How it Works
An undercounter water filtration system is a great way to ensure you have clean drinking water at home. It's installed directly under your kitchen sink and can be connected to your existing plumbing.
The system uses a combination of activated carbon, ion exchange resin, and reverse osmosis to remove impurities and contaminants from the water. This process is often referred to as a three-stage filtration process.
Activated carbon is effective at removing chlorine, lead, and volatile organic compounds (VOCs) from the water, which can affect taste and odor. It's also great at removing particulate matter like sediment and rust.

Ion exchange resin is used to remove heavy metals like lead, mercury, and arsenic from the water. This is especially important for households with older plumbing that may be leaching these toxins into the water.
Reverse osmosis is the final stage of filtration and uses a semi-permeable membrane to remove dissolved solids and other impurities from the water. This process is effective at removing up to 99% of contaminants from the water.
Water Quality
Quality water is at the heart of everything you do, from drinking and cooking to making coffee and tea. An under sink system helps reduce contaminants and improve flavor for all your water needs.
The Coway Plus Innocence Filter has a removal rate of 95.1-98.8% for 15 remnant pharmaceuticals and endocrine disruptors. This is based on the WQA performance test and NSF/ANSI 401 standard.
Cleaner, clearer water can make a big difference in your daily life. You can taste and notice the difference with an under sink water filtration system.
The nanotrap filter and RO 1.0 filter system have some overlap in their purification performance, with both certified for taste and odor removal. However, the nanotrap is certified for class 1 particulate matter, while the RO 1.0 is certified for TDS and hardness.
Having cleaner, clearer ice and better tasting beverages is just one of the benefits of an under sink water filtration system.
