Aquasana 2-Stage Under Sink Water Filter System Review (AQ-5200.55)

Before tap water reaches your house, the local water treatment facility cleans the water to remove chemicals, bacteria, and other harmful particles. However, treated water is not always pure enough to trust, and the quality level constantly varies.

The Aquasana AQ-5200.55 2-Stage Under-Sink Water Filter System uses Claryum technology in its dual filters to eliminate 99 percent of almost 70 contaminants that are commonly found in municipal water supplies while leaving good-for-you minerals such as calcium and potassium.

For mere pennies per gallon, you get fresh, filtered water delivered through a gorgeous brushed-nickel faucet. You can use this water to drink, hydrate your pets, make baby formula and cook meals. This filtration system even has a sound indicator to let you know when it’s time to replace the long-lasting filters.

It Filters Dozens of Impurities

Compared to the 5 contaminants that pitcher-style water filters remove, Aquasana’s 2-Stage Water Filter System eliminates 68 contaminants. NSF 42 and NSF 53 are the two main certifications given by the National Sanitation Foundation to residential water filters, and this water filter possesses both. These certifications mean that the water filter reduces asbestos, chloramines, chlorine, lead, volatile organic compounds and even dangerous parasites like cryptosporidium and giardia.

In addition, the Aquasana 2-stage water filter holds an NSF 401 certification that means it removes herbicides, pesticides, medications, BPA and DEET. It also has an NSF P473 certification, which indicates the water filter meets the American National Standard’s requirements for water-treatment units. With all of these certifications under its belt, you know you are getting pure, clean water in every glass.

It Retains Healthy Minerals

How does Aquasana manage to remove so many dangerous contaminants? It uses an NSF certified and independently-tested filtration technology called Claryum. This technology implements activated carbon and catalytic carbon filters to remove chlorine, organic chemicals and pesticides.

The water goes through an ion-exchange process to filter mercury, lead, and other metals and a sub-micron mechanical filtration process to trap asbestos and waterborne diseases. While the filters work to purify the water, they simultaneously preserve the water’s mineral content, so you still get water that contains potassium, magnesium, and calcium every time you turn on the dedicated faucet with a brushed-nickel finish.

It Has Long-Lasting Filters

This under-sink water filter comes with one set of two filters that provide 500 gallons of purified water at a rate of only 10 cents per gallon, which is significantly less expensive than the price of bottled water from the grocery store. Even better, you only need to replace these filters every 6 months. When your filtration system makes a beeping sound, just open your cabinet, twist open the filter housings and take out the old filters.

Then, replace the old filters with new ones, twist the housings to close them, and you will be ready to enjoy safe, fresh water at a flow rate of 0.5 gallons per minute. It doesn’t get simpler than that.
