I have used an under sink water filter for the last few years and wanted to switch to a different model. I was not happy with the effectiveness or the filter replacement costs of the current model I was using.

I took the opportunity when I moved into a new home to really research and find a good sink filter that would provide me with clean and healthy water for drinking and cooking.

Up until this point I simply used the local water companies filtration units that they offered. When I began to look online I realized that there were a lot more options and competitive pricing.

One of the sink filtration units I heavily researched was the Aquasana under sink water filter. Aquasana has two under sink models, the AQ-4600 and the AQ-4601. The only difference between the two is that the 4601 comes with nicer faucet options.

Below are my findings for the Aquasana 4600 and 4601 under sink water filters …

Filtration Method

These filters use a multi-stage filtration system that is one of the most advanced filtration methods on the market. They use a combination of mechanical filtration, absorption and ion-exchange which is also known as carbon filtration and sub micron filtration.

Their filtration methods have been independently tested and certified by Underwriters laboratories and the California Department of Public Health and they are able to filter up to 30 gallons of clean water per hour.

Their filtration unit consists of two separate filters which filter out 52 contaminants without removing the natural trace minerals that are so important for our health.

The old filtration unit I was using took out all the trace minerals as well and inevitably I had to buy them separately and add them back in. So I like that these units do not kill the trace minerals. It filters out all sorts of nasty toxins such as:

  • 99.9% of MTBE and cysts (chlorine-resistant parasites)
  • chlorine
  • lead
  • prescription drugs
  • gasoline acidities
  • organic chemical compounds
  • disinfectants and by-products
  • bad tastes and odors
  • industrial solvents
  • herbicides and pesticides

With their great quality, awesome warranty and free shipping in North America they are well worth looking into.
