Filtration

Filtering the water is the core task that water filters have to do, what if they failed to do it appropriately? Obviously, you will not go with those failed filters, no matter how much they were easy to install and how stylish they were. Aquasana already knew all of these things, that’s why they have paid great attention to their filtration capabilities.

Aquasana uses the Claryum technology for filtering out the pollutants from the water. Clary technology uses two filtration stages in the whole process.  Furthermore, these two stages are divided into 4 different portions, to ensure that you will get the best purified water.

Activated Carbon: This segment deals with organic chemicals and pesticides.

Catalytic Carbon: It only works to remove two chemicals including chloramine and chlorine. It has been noticed that it removes both of these chemicals up to 98% effectively.

Ion-Exchange: Lead and mercury will get eliminated from the water.

Sub-Micron Mechanical Filtration: Lastly, chlorine-resistant cysts and asbestos get caught at this segment.

Long story short, including chlorine, chloramine, heavy metals, organic chemical, pesticides, and all other possible pollutants gets eliminated by this water filter. But good news! Is that, along with these pollutants, Aquasana AQ 4000 does not remove beneficial minerals from water.

All the beneficial minerals, including potassium, magnesium, and calcium remains in the water so that you don’t have to drink bland taste purified water. The water coming out of this filter is cleanest and healthy at the same time.
