The Aquametix Meets or Exceeds NSF/ANSI Standards 42 & 53 for the following:

Filtering Capacity


One of the chief benefits of the Aquametix filter is its capacity to remove the industrial version of fluoride from water. Fluoride occurs naturally in many water sources and is not harmful but the industrial version of fluoride infused into approximately 73% of American communities is an industrial pollutant which is also used an insecticide and pesticide. The FDA, CDC and Water Quality Association of America refuse to acknowledge that the industrial version of fluoride is a poison. The majority of mainstream water treatment companies in America abide by the Water Quality Association stand that the industrial version of fluoride is healthy and necessary for children and adults thus few water companies will offer filtration for fluoride.


The Under Sink 4 Stage filter system uses standard size 10″ filter cartridge allowing for higher flow rates and longer life. The inlet & outlet are 3/8″ push-fit connectors and includes a DIY installation kit which includes most parts needed for installation, including a faucet, tubing, mounting bracket & screws, and fittings.

    “I remember reading about the cattle going only to the structured water trough. I have a German ShortHaired Pointer. Gave him two identical bowls of original tap water and the other was structured water. He wouldn’t drink the tap water that he always drank. Pretty wild!!”

    I purchased a structuring unit for my parents who are in their eighties. They reported two notable events:

    My father’s asthma attacks were easier to manage.
    My mom’s dementia stabilized.

    Product is EXCELLENT. Tastes amazing, was easy-ish to install. Only issues: I live in Canada so there was a 15% duty charge upon arrival and shipping was pricey (but greenfield was kind enough to offer a discount to help with some of that), and it took about 3.5 weeks to arrive. They also forgot to include one of the parts necessary for installation (honest mistake) and it took an extra week or two to wait for that piece before receiving and actually being able to install. Since then, no issues and super happy!

    So far we are loving our under sink filter, can’t wait to get the whole house system once our house is finished! The team was also super helpful in guiding me on what to purchase.

    Loving the fact that I have access to filtered and mineralized water at home for my family. I had all my questions answered by customer service when they helped me choose the correct water filter I needed. They provided installation support via videos.
