FAQ's

What Does Deionization Do?

Deionization (DI) is the process of cleaning or polishing water. It usually goes hand in hand with reverse osmosis (RO) in a Water Fed system. First, it goes through reverse osmosis, then to an RO membrane, and lastly through deionization housing for water polishing.

To keep your pure water system effective, you need to replace your resin cartridge from time to time. Virgin resin, which is the component used to remove total dissolved solids (TDS) from the tap, can wear out over time. You may check the effectiveness of your resin by using a TDS meter on your purified H2O.

Where Can You Use a Deionization Filter?

Deionized H2O has a lot of uses, mostly for laboratory purposes. But it’s more commonly known as the ideal water for a window cleaning Water Fed system. Purified H2O has a TDS of 0, which allows it to clean glass and surfaces spot-free. Its use is the standard among professional window cleaning services, as it eliminates the need for final polishing only to remove smears.

How Often Should You Change Your Deionization Resin?

The ion exchange resin can exhaust its capacity to remove contaminants over time. This is why it’s important to regularly replace them. However, the lifespan of a deionization filter varies depending on the quality of the water involved. If the supply has a great amount of TDS in it, it’s more likely to wear out your resin. It’s best to check the TDS level of your H2O. A high level should tell you that your deionization resin needs replacement.
