This reverse osmosis under-counter filter uses no less than 5 different filtration stages in order to ensure that the water you drink and cook with is of a superior quality. During the first filtration stage, sediments, dust, rust, sand, and other similar particles are removed. In the second stage of filtration, chlorine, water cloudiness, and unpleasant tastes and odors are eliminated. In the third stage, the CTO filter removes cloudiness, harmful chemicals, volatile organic compounds, and other contaminants. During the fourth filtration stage, the reverse osmosis membrane removes impurities and contaminants as small as 0.0001 microns that have remained in the water. Last but not least, during the final filtration stage, all remaining residual tastes and odors are eliminated. To better understand how great the performance of this water filter is, know that it can remove up to 99 percent of heavy metals, chemicals, sediment, and other contaminants that it finds in the water. Overall, it handles removing more than 1000 contaminants found in tap water, thus being one of the most effective products of this kind on the market. Other performance aspects worth taking into consideration are the fact that it delivers a daily production rate of 75 gallons of water and a maximum flow rate of 0.05 GPM. Best of all, the sediment, GAC, CTO, and inline carbon filters have a lifespan of up to 12 months, while the reverse osmosis membrane can last for up to 3 years before it needs to be replaced.


The model features a sediment filter, a GAC carbon filter, a CTO carbon filter, a reverse osmosis element, and an inline carbon filter that all work together to ensure that high-quality, clean water comes out of the tap. Due to the fact that the first three filtration elements remove the larger contaminants, they are known as pre-filters, having the job of removing these large particles in order to protect the reverse osmosis membrane. Unfortunately, the lack of a UV light shows that it’s not the most effective solution when it comes to eliminating the bacteria and germs that might lurk in your drinking water, this being a big flaw considering that other models have this capability.
