Aquasana FAQs
1. Do I have to pay for a plumber to install the system?
Our under sink drinking water filter systems are easy to install, and a plumber is not required. If you have any questions or need assistance, please call our Customer Support line at 877-996-2875. Or, follow the link below to our replacement videos:
Claryum® 2-Stage
Claryum® 3-Stage
Claryum® 3-Stage Max Flow
We recommend changing the filter cartridges every 3 to 6 months, depending upon the specific filter gallon capacity. Regularly changing the filters prevents the growth of bacteria in the system and continues to deliver clean, healthy water. The filter capacity varies between each system:
Claryum® 2-Stage: 500 gallon capacity
Claryum® 3-Stage: 600 gallon capacity
Claryum® 3-Stage Max Flow: 800 gallon capacity
Due to the nature of the carbon blocks assembly and the contents of a used filter, the filters cannot be recycled.
Claryum® technology is a selective filtration process that uses sub-micron filtration, micron filtration, and adsorption. Together, these technologies reduce up to 99% of 77 contaminants from water while maintaining healthy minerals like calcium, magnesium, and potassium.
No, this is not purified water, it is filtered water. Purified water undergoes reverse osmosis or distillation, which strips everything out of your water - not only the contaminants, but also the healthy, natural minerals. Our systems use selective filtration designed to reduce contaminants from the water and leave in the natural healthy minerals like calcium, potassium, and magnesium.
TDS, or Total Dissolved Solids, is the amount of dissolved minerals and metals present in water. TDS meters tell you the concentration of dissolved minerals and metals but are not an accurate measurement for contamination. Aquasana products reduce and remove harmful TDS like lead, but selectively retain or replace healthy dissolved solids like calcium, magnesium, and potassium. Read more about TDS here.
BPA stands for Bisphenol-A, a contaminant found in most plastics. BPA can adversely affect your health if consumed at high levels. Aquasana drinking systems do not contain BPA, and our filtration process reduces existing BPA.
No, hard water is not always considered contaminated. Most water sources in the USA are considered hard.
Hard water can be city water or well water meaning it may or may not be pre-treated. The minerals that make water "hard" are not considered contaminants, but hard water can still contain additional contaminants that are not safe for consumption.
Soft water is water that has either been treated by a water softener or naturally contains less hard minerals. The most recognizable trait of "soft" water is how much more soap lathers, as opposed to hard water.  Soap lathers less due to the higher concentration of minerals. Water softeners reduce the negative effects of dissolved minerals in water that can clump together and produce scale buildup.
Soft water does not mean clean water. Your water can be soft and still have contaminants present in the water.
Yes, soft water is considered potable. Drinking water from a sodium-based softener increases your daily intake of sodium, which can lead to health problems in sodium-sensitive individuals. Please keep in mind that a water softener is not a water filter. A water softener does not remove contaminants present in your water.
