Drinking Water Filter Systems for Healthy, Great-Tasting Water

You use your drinking water for everything -- from washing vegetables to filling your family's glasses at dinner. For most homes, municipalities treat drinking water with chemicals including chlorine and chloramines to rid it of contaminants. While chlorine and chloramines are successful in treating bacteria in your water, they can miss certain contaminants that are harmful to your overall health and wellbeing. That's why you should protect your family with a drinking water filter system.

Aquasana's drinking water filter systems reduce 15x more contaminants than the leading pitcher filter. Our superior NSF certified Claryum filtration technology reduces up to 99% of lead and other contaminants including VOCs, cysts, asbestos, herbicides, pesticides, chlorine, chloramines, and much more. All while retaining naturally-occuring minerals— like calcium, magnesium, and potassium— that improve the pH balance and nutrition of your water.

Choose the Best Type of Drinking Water Filter for Your Home

Choosing a drinking water filtration system is easy. First, determine whether you need an under counter filter or a countertop solution.

An under counter system is installed under your sink and includes a dedicated faucet from which to pull your filtered water. Our under counter solutions include our OptimH2O Reverse Osmosis + Claryum Filter and our 2- and 3-Stage Claryum filters.

Our countertop solutions — including the Countertop Water Filter and the Clean Water Machine— require no permanent fixtures or installation. Our popular Clean Water Machine holds a gallon of purified water and offers versatile placement anywhere within the home.

Next, determine which contaminants are the most important to filter out of your home. If you are looking to reduce the highest number of contaminants, our Reverse Osmosis + Claryum Filter may be the choice for you. It reduces 95% of fluoride and mercury, 97% of chlorine and arsenic, and 99% of lead and asbestos and more. While some RO systems are so efficient at removing solids that they remove healthy minerals at the same time, we pair our RO system with our Claryum® technology to restore a good pH balance, along with calcium, magnesium, and potassium to your drinking water.

Our other under counter filters are also great contaminant reducers. Our Claryum 3-Stage Max Flow, Claryum 3-Stage Under Counter and Claryum 2-Stage Under Counter filters are all NSF certified to reduce chlorine, chloramines, herbicides, pesticides, pharmaceuticals and more.

Additionally, both the Countertop Water Filter and Clean Water Machine use NSF certified Claryum filtration technology proven to remove up to 99% of lead and asbestos, as well as up to 96% of chlorine, chloramines and 73 other harmful contaminants.
