Capacity: The unit can soften approximately 20,000 gallons of hard water per cartridge (1st one comes with the package).

DPHB is a pretty basic water softener. It offers you several advantages. Moreover, the effect on water is of the highest standard.

Of course, the 12 to 15 GPM is undoubtedly a pretty good flow rate and it won’t slow down your household water flow. At this flow rate, you can run a washing machine, dishwasher, two faucets, and two showers. At the same time, you can also water your lawn without experiencing a single drop in water pressure.

Although its cartridge length is somewhat unusual (20-inch), the overall dimensions of the unit are very modest. And due to its super compact size, you can install it in tight spaces.

The only downside of this model is its smaller cartridge size that you may need to replace after every 20,000 gallons or based on how large your household is.
