Northstar NST30UD

Northstar NST30UD Ultra Demand

The Northstar NST30UD Ultra Demand comes with a Look Ahead technology that makes predictions about the performance of this water softener. Suppose the filters are too dirty. The Look Ahead mechanism would indicate that you need to change the filters because the softener is not working at its optimum level.

Another reason that makes this water softener stand out is it can assess the approximate water quantity that your family needs. It records the average water use every day and accordingly suggests the amount of water required for your family. This helps to save a lot of water as you become aware of the average quantity of water you should use in one day.

In addition to assessing the water consumption and performance determinant, this water softener also allows you to regulate the softening level. This is very helpful in regions where people only get hard water. You can notch the setting to its highest level to make the water soft. But you also need to remember that using the softener at its highest capacity will mean refining a lot of impurities within a short period. You may need to change the filters of the softener in that case.

The design and compact size is another reason why you should consider buying this water softener. It looks small but is capable enough to handle gallons of water without requiring frequent filter changes. The two tanks come with a lining, keeping them firm and stable for years. It also has a diagnosis feature that lets you track the performance of the softener from time to time. You will also see a resin bed in this water softener that constantly moves to keep the filters free from accumulating iron or dirt.

The Look Ahead technology is like the brain of this water softener. This is North Star’s patented program that monitors the quality of water you use, the quantity of water you use, and then determines the time to regenerate the softener.

This is another unique feature of the Northstar NST30UD Ultra Demand. It draws brine water into the bottom of the resin tank that further enhances the regeneration process. This is the ideal method to soften water that only a handful of brands follow.

The double lining provides strength and durability to the tanks that in turn ensure that the water softener lasts for years.
