What is the maximum height you need to work at?
Enter the approximate height of the highest point you need to clean.
How many hours per week do you use the system?
Intensive use with hard water consumes a lot of resin — above a certain volume, nanofiltration or reverse osmosis can be more economical.
Do you know the water hardness in your area?
Hard water uses more resin. If you do not know the hardness, select your country and province and we will estimate it for you.
Estimated data based on the provincial capital. It may vary depending on your municipality.
Do you need to transport the equipment frequently?
Some systems include a trolley to make transport easier.
What is your approximate budget?
Including equipment + pole + all accessories needed to start working.
What performance can you expect from a HydroPower DI with your water?
Enter your actual ppm or select your area to get an estimated guide to litres, working hours and surface area.
Calculator range: 1–2,000 ppm.
The area value is an approximate reference, not a measurement taken at your property.

At this ppm level, a HydroPower DI system may be uneconomical for regular use. We recommend considering a reverse osmosis system such as the Unger RO S.
Unger reference: incoming water TDS 275 ppm, output <10 ppm; laboratory values and approximate coverage. Values between reference points are calculator estimates, not an official Unger table.
