“Dissolved solids” refer to any minerals, salts, metals, cations or anions dissolved in water. This includes anything present in water other than the pure water (H20) molecule and suspended solids. So when we refer to TDS, we are measuring your water quality or how hard (or soft) your water is. Your TDS and how often you plan on using your system (daily, frequently, infrequently, etc.) are two of the most important factors in choosing a waterfed purification system.
Simply put, the lower the TDS, the lower your purification system cost can be.
If you are looking for a complete option, we have that available too! We recommend looking at the XERO DI Package. It comes with a 1/2 Cubic Foot DI Tank and the XERO pole of your choice. The Unger HydroPower Ultra Packageis another complete option for those with softer water. You can choose your Unger HydroPower system and pair it with a premium Unger water fed pole.
A DI tank will NOT be a cost-effective method of purification. You need a Multistage System.
Here's an example:
Let's say your water is 222ppm and you are using a standard DI tank. You would only expect to produce around 700 gallons of work for 23 working hours at a cost of $99 per resin refill. Now, let's compare to that if you were using a multi-stage system like the Xero Pure. You can expect to produce about 5,500 gallons or work for 184 hours before spending $59 to refill the resin. So to produce the same 5,500 gallons through a DI tank only would cost you roughly $800. See where the savings compounds over time?
